Organization and Significant Accounting Policies | 1. Organization and Significant Accounting Policies Organization The Company is a global leader in the design, engineering, and manufacture of production tools, modules and subsystems for the semiconductor capital equipment industry and industry segments with similar requirements including consumer, medical and flat panel display. The Company focuses on providing specialized engineering and manufacturing solutions for these applications. The Company enables its customers to realize lower manufacturing costs and reduced design-to-delivery cycle times while maintaining high quality standards. The Company provides its customers with complete solutions that combine its expertise in design, scan, assembly, test and component characterization. The Company’s customers value its highly flexible global manufacturing operations, its excellence in quality control and its scale and financial stability. The Company’s global footprint enables the Company to reduce manufacturing costs and design-to-delivery cycle times and maintains high quality standards for the Company’s customers. The Company believes that these characteristics allow the Company to provide global solutions for its customers’ growing product demands. The Company ships the majority of its products to U.S. registered customers with locations both in and outside the U.S. In addition to its U.S. manufacturing capabilities, the Company manufactures products in its Asian facilities to support local and U.S. based customers. The Company conducts its operating activities primarily through its wholly owned subsidiaries, Ultra Clean Technology Systems and Service, Inc., AIT LLC, Ultra Clean Technology (Shanghai) Co., Ltd., Ultra Clean Micro-Electronics Equipment (Shanghai) Co., Ltd., Ultra Clean Asia Pacific, Pte Ltd. (Singapore), Marchi and Miconex. The Company’s international sales represented 35.6% and 30.7% of total sales for the three months ended September 25, 2015 and September 26, 2014, respectively, and 33.3% and 29.5% of total sales for the nine months ended September 25, 2015 and September 26, 2014, respectively. See Note 10 to the Company’s Condensed Consolidated Financial Statements for further information about the Company’s geographic areas. Basis of Presentation Principles of Consolidation Foreign Currency Translation and Remeasurement Use of Accounting Estimates Certain Significant Risks and Uncertainties Concentration of Credit Risk Significant sales to customers Three months ended Nine months ended September 25, September 26, September 25, September 26, Lam Research Corporation 49.4 % 39.3 % 50.4 % 36.0 % Applied Materials, Inc. 26.4 20.9 27.1 22.0 ASM International * 13.9 * 17.0 Total 75.8 % 74.1 % 77.5 % 75.0 % * Total sales for the period are below 10%. Three customers’ accounts receivable balances, Applied Materials, Inc., Lam Research Corporation and ASM International, were individually greater than 10% of accounts receivable as of September 25, 2015 and December 26, 2014 and in the aggregate represented approximately 79.9% and 73.7% of accounts receivable, respectively. Fair Value of Measurements — Level 1 — Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 — Inputs that are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant inputs are observable in the market or can be derived from observable market data. Where applicable, these models project future cash flows and discount the future amounts to a present value using market-based observable inputs including interest rate curves, foreign exchange rates, and credit ratings. Level 3 — Unobservable inputs that are supported by little or no market activities. The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. Derivative Financial Instruments Inventories Inventory write downs inherently involve judgments as to assumptions about expected future demand and the impact of market conditions on those assumptions. Although the Company believes that the assumptions it used in estimating inventory write downs are reasonable, significant changes in any one of the assumptions in the future could produce a significantly different result. There can be no assurances that future events and changing market conditions will not result in significant increases in inventory write downs. Equipment and Leasehold Improvements Product Warranty — Nine months ended September 25, 2015 September 26, 2014 Beginning balance $ 109 $ 101 Change in reserve 300 97 Warranty costs incurred in the current period (225 ) (85 ) Ending balance $ 184 $ 113 Income Taxes The Company continued to maintain a full valuation allowance on its California, Oregon, and one of its Chinese subsidiaries deferred tax amounts as of September 25, 2015 totaling $3.2 million. Income tax positions must meet a more likely than not recognition threshold to be recognized. Income tax positions that previously failed to meet the more likely than not threshold are recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more likely than not threshold are derecognized in the first subsequent financial reporting period in which that threshold is no longer met. The Company recognizes potential accrued interest and penalties related to unrecognized tax benefits within the consolidated statements of income as income tax expense. The calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. Resolution of these uncertainties in a manner inconsistent with the Company’s expectations could have a material impact on its results of operations and financial position. Management believes that it has adequately provided for any adjustments that may result from these examinations; however, the outcome of tax audits cannot be predicted with certainty. The determination of the Company’s tax provision is subject to judgments and estimates. Revenue Recognition Research and Development Costs Net Income per Share Segments Business Combinations Stock-Based Compensation Expense The Company maintains stock-based compensation plans which allow for the issuance of equity-based awards to executives, directors and certain employees. These equity-based awards include stock options, restricted stock awards (“RSAs”) and restricted stock units (“RSUs”) which can be either time-based or performance-based. The Company also maintains an employee stock purchase plan that provides for the issuance of shares to all eligible employees of the Company at a discounted price. Stock-based compensation expense includes compensation costs related to estimated fair values of stock options and awards granted. The estimated fair value of the Company’s equity-based awards, net of expected forfeitures, is amortized on a straightline basis over the awards’ vesting period, typically four years for stock options, three years for RSUs and one year for RSAs, and is adjusted for subsequent changes in estimated forfeitures related to all equity-based awards and performance as it relates to performance-based RSUs. The Company applies the fair value recognition provisions based on the FASB’s guidance regarding stock-based compensation. The exercise price of each stock option equals the market price of the Company’s stock on the date of grant. Most options are scheduled to vest over four years and expire no later than ten years from the grant date. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model. The determination of the fair value of share-based payment awards on the date of grant using an option-pricing model is affected by the Company’s stock price as well as assumptions regarding certain variables. These variables include the expected term of the awards; the Company’s expected stock price volatility over the term of the awards, actual and projected employee stock option exercise behaviors, the risk-free interest rate and expected dividends. The Company estimates the expected term of share-based awards granted based on the Company’s historical option term experience. The Company estimates the volatility of its common stock based upon the Company’s historical stock price volatility over the length of the expected term of the options. The Company bases the risk-free interest rate that it uses in the option valuation model on U.S. Treasury zero-coupon issues with remaining maturities similar to the expected term of the options. The Company does not anticipate paying any cash dividends in the foreseeable future and therefore uses an expected dividend yield of zero in the option valuation model. The Company is required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. The Company uses historical data to estimate pre-vesting option forfeitures and records share-based compensation expense only for those awards that are expected to vest. The Company also considers, each quarter, whether there have been any significant changes in facts and circumstances that would affect its estimated forfeiture rate. Stock Options Stock option activity for the nine months ended September 25, 2015: Shares Weighted Weighted Aggregate Outstanding at December 26, 2014 853,551 $ 8.87 1.35 $ 1,798 Granted — — Exercised (339,303 ) $ 6.48 Canceled (197,600 ) $ 11.18 Outstanding at September 25, 2015 316,648 $ 10.01 2.31 $ 234,133 Options exercisable at September 25, 2015 316,648 $ 10.01 2.31 $ 234,133 There were no options granted by the Company during either of the nine month periods ended September 25, 2015 and September 26, 2014. As of September 25, 2015, there was no stock-based compensation expense attributable to stock options as all outstanding options were fully vested. Employee Stock Purchase Plan The Company also maintains an employee stock purchase plan (“ESPP”) that provides for the issuance of shares to all eligible employees of the Company at a discounted price. Under the ESPP, substantially all employees may purchase the Company’s common stock through payroll deductions at a price equal to 95 percent of the fair market value of the Company’s stock at the end of each applicable purchase period. Restricted Stock Units and Restricted Stock Awards The Company grants RSUs to employees and RSAs to non-employee directors as part of the Company’s long term equity compensation plan. Restricted Stock Units During the quarter ended March 27, 2015, the Company granted 456,500 RSU’s, with a weighted average fair value of $8.68 per share, and granted 90,500 performance stock units with a weighted average fair value of $8.35 per share. During the quarter ended June 26, 2015, the Company granted 134,000 RSU’s, with a weighted average fair value of $6.53 per share. The Company granted 103,500 RSU’s with a weighted average fair value of $6.71 per share during the quarter ended September 25, 2015. During the nine months ended September 25, 2015, 39,938 vested shares were withheld to satisfy withholding tax obligations, resulting in the net issuance of 337,443 shares. As of September 25, 2015, approximately $ 6.8 million of stock-based compensation cost, net of estimated forfeitures, related to RSU’s remains to be amortized over a weighted average period of 2.1 years. As of September 25, 2015, a total of 1,277,741 RSU’s remain outstanding with an aggregate fair value of $6.8 million and a weighted average remaining contractual term of 1.3 years. Restricted Stock Awards The following table summarizes the Company’s RSU and RSA activity for the nine months September 25, 2015: Shares Aggregate Unvested restricted stock units and restricted stock awards at December 26, 2014 1,078,279 $ 9,673 Granted 840,500 Vested (424,381 ) Forfeited (216,657 ) Unvested restricted stock units and restricted stock awards at September 25, 2015 1,277,741 $ 6,800 Vested and expected to vest restricted stock units and restricted stock awards at September 25, 2015 1,076,186 $ 5,686 The following table shows the Company’s stock-based compensation expense included in the condensed consolidated statements of operations (in thousands): Three months ended Nine months ended September 25, 2015 September 26, 2014 September 25, 2015 September 26, 2014 Cost of sales (1) $ 304 $ 267 $ 908 $ 862 Research and development 658 100 1,247 245 Sales and marketing 49 119 150 334 General and administrative 103 671 302 1728 1,114 1,157 2,607 3,169 Income tax benefit (310 ) (226 ) (746 ) (1,056 ) Net stock-based compensation expense $ 804 $ 931 $ 1,861 $ 2,113 (1) Stock-based compensation expenses capitalized in inventory for the three and nine month periods ended September 25, 2015 and September 26, 2014 were considered immaterial. Recent Accounting Pronouncements In September 2015, the Financial Accounting Standards Board (FASB) issued updated guidance on the accounting for purchase accounting adjustments determined during the measurement period (i.e. up to one year after the acquisition). The new guidance requires an acquirer to recognize such adjustments in the reporting period in which the adjustment amounts are determined. Previously, such adjustments were required to be recorded on a retrospective basis. The Company has elected to early adopt this guidance beginning in the third quarter 2015 on a prospective basis. The adoption of this guidance did not have a significant impact on the condensed consolidated financial statements. In July 2015, the FASB issued authoritative guidance that requires inventory to be measured at the lower of cost and net realizable value instead of at lower of cost or market. This guidance does not apply to inventory that is measured using last-in, first out (LIFO) or the retail inventory method but applies to all other inventory including those measured using first-in, first-out (FIFO) or the average cost method. The authoritative guidance will be effective for the Company in the first quarter of fiscal 2018 and should be applied prospectively. Early adoption is permitted as of the beginning of an interim or annual reporting period. The Company is currently evaluating the effect of this new guidance on the Company’s consolidated financial statements. In April 2015, the FASB issued authoritative guidance that requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability, consistent with debt discounts. The authoritative guidance is effective for the Company in the first quarter of fiscal 2017 and should be applied retrospectively. Early adoption is permitted. The adoption of this guidance is not expected to have a significant impact on the Company’s consolidated financial statements. |

Financial Instruments | 2. Financial Instruments Cash Equivalents The Company has an overnight sweep account invested in money market funds with maturities of less than 90 days from purchase and is thus classified as cash and cash equivalents on the Company’s balance sheet. These money market funds had a carrying value and fair value of $0.3 million at September 25, 2015 based on Level 1 inputs. Derivative Financial Instruments A subsidiary of the Company, Miconex, utilizes foreign currency forward contracts with a local financial institution to reduce the risk that its cash flows and earnings will be adversely affected by foreign currency exchange rate fluctuations. The Company also uses certain interest rate derivative contracts to hedge interest rate exposures on existing floating rate debt. The Company classifies its foreign currency and interest rate derivative contracts primarily within Level 2 of the fair-value hierarchy discussed in Note 1of the Company’s Condensed Consolidated Financial Statements as the valuation inputs are based on quoted prices and market observable data of similar instruments. Cash Flow Hedges In September 2015, the Company entered into an interest rate swap with East West and City National banks with a notional amount of $20.0 million pursuant to which the Company pays the counterparty a fixed rate of 0.99% and receives interest at a variable rate equal to the LIBOR rate the Company is required to pay under its term loan, or 0.2%, as of September 25, 2015. This interest rate swap effectively locks in a fixed interest rate of 3.49% on $20.0 million of the $37.5 million term loan balance outstanding as of September 25, 2015, with a decreasing notional amount based on prorated quarterly principal payments over the remaining period of the term loan. Gains or losses on the effective portion of a cash flow hedge are reflected as a component of AOCI and subsequently recorded to interest income (expense) when the hedged transactions are realized. If the hedged transactions become probable of not occurring, the corresponding amounts in AOCI would be immediately reclassified to interest and other income, net. As of September 25, 2015, the effective portion of the Company’s cash flow hedge before tax effect was $0.1 million, of which $0.1 million is expected to be reclassified from AOCI into earnings within the next 12 months. Non-Designated Derivatives Miconex derivatives are not designated as hedging instruments and consist of: a) forward contracts that Miconex uses to hedge forecasted transactions that are denominated in currencies other than the local currency of Miconex, and b) an interest rate swap with a total notional amount of $0.5 million to convert the variable interest rates on Miconex debt to fixed interest rates. The Company recognizes gains and losses on these contracts, as well any related costs in interest and other income, net. The notional principal of foreign exchange contracts outstanding was $1.3 million as of September 25, 2015 and $0 as of December 26, 2014. The Company records all derivatives in the Condensed Consolidated Balance Sheets at fair value. The Company’s accounting treatment for these derivative instruments is based on its hedge designation. The following tables show the Company’s derivative instruments at gross fair value (in thousands) as of September 25, 2015. There were no derivative instruments as of December 26, 2014.

The effect of derivative instruments not designated as hedging instruments on income for the three and nine months ended September 25, 2015 and September 26, 2014 is immaterial to the financial statements. |

Acquisitions | 4. Acquisitions Miconex On July 31, 2015, the Company acquired 100.0% of the shareholding interest of Miconex, a limited liability company incorporated under the laws of the Czech Republic and a provider of advanced precision fabrication of plastics, primarily for the semiconductor industry. This acquisition is expected to expand the Company’s capabilities with existing customers. Pursuant to the purchase agreement, the Company paid $15.0 million in cash and issued 500,000 shares of the Company’s common stock. In addition, the former owners of Miconex are entitled to up to $4.0 million of potential cash “earn-out” payments over a two-year period following closing, based on Miconex’s achievement of specified performance targets based on EBIT (earnings before interest and taxes) pursuant to the provisions of the purchase agreement. The preliminary estimated acquisition price of Miconex for purposes of the Company’s preliminary purchase price allocation was determined to be $20.1 million, which includes the cash payment of $15.0 million, the stock consideration valued at $3.8 million, and the fair value of the potential earn-out payments of approximately $1.3 million. The fair value of the common stock issued was determined based on the average of the high and low trading prices per share of the Company’s common stock on the acquisition date of approximately $7.64 per share. The fair value of the earn-out payments at the acquisition date was determined providing risk adjusted earnings projections using the Monte Carlo Simulation. These inputs are not observable in the market and thus represent a Level 3 measurement as discussed in Note 1 of the Company’s Condensed Consolidated Financial Statements. As of September 25, 2015, there were no significant changes in the fair value of the earn-out. The Company preliminarily allocated the purchase price of Miconex to the tangible and intangible assets acquired and liabilities assumed based on their estimated fair values. The excess of the purchase price over the aggregate fair value was recorded as goodwill. Goodwill associated with this acquisition is primarily attributable to future technology, market presence and knowledgeable and experienced workforce. The fair value assigned to identifiable intangible assets acquired was determined using the income approach taking into account the Company’s consideration of a number of inputs, including an independent third party analysis that was based upon estimates and assumptions provided by the Company. These estimates and assumptions were determined through established and generally accepted valuation techniques. The primary areas of the preliminary purchase price allocation yet to be finalized relate to the fair value of certain tangible assets and liabilities acquired, income and non-income based taxes and residual goodwill. During the measurement period, which can be no more than one year from the date of acquisition, we expect to continue to obtain information to assist us in determining the final fair value of the net assets acquired at the acquisition date. The preliminary purchase price for this acquisition has been allocated as follows: Fair Market Values (in thousands) Cash and cash equivalents $ 239 Accounts receivable 3,065 Inventories 6,198 Deferred tax assets 196 Prepaid expenses and other 214 Equipment and leasehold improvements 428 Goodwill 10,197 Purchased intangible assets 8,800 Total assets acquired 29,337 Bank borrowings (3,027 ) Accounts payable (3,509 ) Accrued compensation and related benefits (432 ) Other current liabilities (576 ) Deferred tax liability (1,672 ) Other liabilities (24 ) Total liabilities assumed (9,240 ) Purchase price allocated $ 20,097 Useful Life Purchased Intangible (In years) (In thousands) Customer relationships 7.5 $ 8,800 Goodwill is not amortized but is reviewed for impairment at least annually and whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. Although goodwill is not amortized for financial accounting purposes, it is amortized in its entirety for tax purposes over fifteen years. The results of operations for the Company for the three and nine month periods ended September 25, 2015 include two months of operating activity for Miconex. For the three and nine months ended September 25, 2015, net sales of approximately $5.2 million and operating income of approximately $0.4 million attributable to Miconex were included in the consolidated results of operations. For the three and nine months ended September 25, 2015, results of operations included charges of $0.2 million attributable to amortization of purchased intangible assets and $0.4 million of deal costs associated with the acquisition. Deal costs are included in general and administrative expenses in the Company’s Condensed Consolidated Statements of Operations. Marchi On February 5, 2015, the Company acquired 100.0% of the shareholding interest of Marchi, a designer and manufacturer of specialty thermocouples, heaters and temperature controllers, for approximately $29.9 million in cash and 1,437,500 shares of newly issued common stock for a total purchase price of approximately $43.7 million. In addition, the Company incurred approximately $0.2 million of costs related to the acquisition. The Company completed this acquisition primarily in order to expand its capabilities with existing customers and to bring the Company closer to the customer in the design stage of new products and next generation equipment. The Company financed the cash portion of the acquisition by borrowing a total of $29.7 million under a new Credit Agreement. See further discussion of the borrowing arrangements in Note 6 to the Company’s Condensed Consolidated Financial Statements. The Company allocated the preliminary purchase price of Marchi to the tangible assets, liabilities and identifiable intangible assets acquired, based on their estimated fair values. The excess of purchase price over the aggregate fair value was recorded as goodwill. Goodwill associated with the Marchi acquisition is primarily attributable to the future technology, market presence and knowledgeable and experienced workforce. The fair value assigned to identifiable intangible assets acquired was determined using the income approach taking into account the Company’s consideration of a number of inputs, including an independent third party analysis that was based upon estimates and assumptions provided by the Company. These estimates and assumptions were determined through established and generally accepted valuation techniques. The estimated fair value of the tangible and intangible assets acquired was allocated at Marchi’s acquisition date. The primary areas of the preliminary purchase price allocation that are not yet finalized relate to the fair values of inventory, non-income based taxes and residual goodwill. During the measurement period, which can be no more than one year from the date of acquisition, we expect to continue to obtain information to assist us in determining the final fair value of the net assets acquired at the acquisition. The preliminary purchase price for this acquisition has been allocated as follows: Fair Market Values (in thousands) Inventories $ 1,297 Equipment and leasehold improvements 767 Goodwill 18,380 Purchased intangible assets 23,370 Other non-current assets 26 Total assets acquired 43,840 Other liabilities (100 ) Total liabilities assumed (100 ) Purchase price allocated $ 43,740 Useful Life Purchased Intangible (In years) (In thousands) Customer relationships 10 $ 9,900 Trade name 6 1,170 Intellectual properties/know-how 8-12 12,300 Total purchased intangible assets $ 23,370 The results of operations for the Company for the nine month period ended September 25, 2015 include eight full months of operating activity for Marchi. For the three and nine months ended September 25, 2015, net sales of approximately $3.9 million and $10.1 million, respectively and operating income of approximately $1.7 million and $4.4 million, respectively attributable to Marchi were included in the consolidated results of operations. For the three and nine months ended September 25, 2015, results of operations included charges of $0.7 million and $1.7 million, respectively, attributable to amortization of purchased intangible assets and $0.2 million of deal costs associated with the acquisition. Deal costs are included in general and administrative expenses in the Company’s consolidated results of operations. The following unaudited pro forma consolidated results of operations assume the Marchi and Miconex acquisitions were completed as of the beginning of the year of the reporting periods presented (in thousands, except per share amounts): Three Months Ended Nine Months Ended September 25, 2015 September 26, 2014 September 25, 2015 September 26, 2014 Net sales $ 127,348 $ 126,857 $ 386,889 $ 428,703 Net income $ 1,560 $ (4,301 ) $ 6,049 $ 11,414 Basic earnings per share $ 0.05 $ (0.14 ) $ 0.19 $ 0.37 Diluted earnings per share $ 0.05 $ (0.14 ) $ 0.19 $ 0.36 The unaudited pro forma results above include adjustments related to the purchase price allocation and financing of the Marchi and Miconex acquisitions, primarily to increase amortization for the identifiable intangible assets, to increase interest expense for the additional debt incurred to complete the acquisition of Marchi, to reflect the related income tax effect of the pro forma adjustments and to adjust weighted shares issued as part of the acquisitions. The unaudited pro forma results for the three and nine months ended September 25, 2015 include acquisitions related costs of $0.6 million which are not expected to occur in future quarters. The unaudited pro forma condensed combined financial information has been prepared by management for illustrative purposes only and are not necessarily indicative of the condensed consolidated financial position or results of income in future periods or the results that actually would have been realized had UCT, Marchi and Miconex been a combined company during the specified periods. The unaudited pro forma condensed combined financial information does not reflect any operating efficiencies and/or cost savings that we may achieve with respect to the combined companies, or any liabilities that may result from integration activities. |

Goodwill and Intangible Assets Disclosure [Abstract] | |
Goodwill and Purchased Intangible Assets | 5. Goodwill and Purchased Intangible Assets The Company’s methodology for allocating the purchase price relating to acquisitions is determined through established and generally accepted valuation techniques. Goodwill is measured as the excess of the cost of the acquisition over the sum of the amounts assigned to tangible and identifiable intangible assets acquired less liabilities assumed. The Company assigns assets acquired (including goodwill) and liabilities assumed to one or more reporting units as of the date of acquisition. Typically, acquisitions relate to a single reporting unit and thus do not require the allocation of goodwill to multiple reporting units. If the products obtained in an acquisition are assigned to multiple reporting units, the goodwill is distributed to the respective reporting units as part of the purchase price allocation process. Goodwill and purchased intangible assets with indefinite useful lives are not amortized, but are reviewed for impairment at least annually and whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. The Company regularly monitors current business conditions and other factors including, but not limited to, adverse industry or economic trends and lower projections of profitability that may impact future operating results. To test goodwill for impairment, the Company first performs a qualitative assessment to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying value. If it is concluded that this is the case, the Company then performs the two-step goodwill impairment test. Otherwise, the two-step goodwill impairment test is not required. Under the two-step goodwill impairment test, the Company would in the first step compare the estimated fair value of each reporting unit to its carrying value. The Company determines the fair value of each of its reporting units based on a weighting of income and market approaches. If the carrying value of a reporting unit exceeds its fair value, the Company would then perform the second step of the impairment test in order to determine the implied fair value of the reporting unit’s goodwill. If the Company determines that the carrying value of a reporting unit’s goodwill exceeds its implied fair value, the Company would record an impairment charge equal to the difference. The evaluation of goodwill and intangible assets for impairment requires the exercise of significant judgment. In the event of future changes in business conditions, the Company will be required to reassess and update its forecasts and estimates used in future impairment analyses. If the results of these future analyses are lower than current estimates, a material impairment charge may result at that time. Details of goodwill and other intangible assets were as follows (in thousands): September 25, 2015 December 26, 2014 Goodwill Intangible Assets Total Goodwill Intangible Assets Total Carrying amount $ 84,495 $ 44,952 $ 129,447 $ 55,918 $ 16,824 $ 72,742 Purchased Intangible Assets Intangible assets are generally recorded in connection with a business acquisition. The Company evaluates the useful lives of its intangible assets each reporting period to determine whether events and circumstances require revising the remaining period of amortization. In addition, the Company reviews indefinite lived intangible assets for impairment when events or changes in circumstances indicate their carrying value may not be recoverable and tests definite lives intangible assets at least annually for impairment. Management considers such indicators as significant differences in product demand from the estimates, changes in the competitive and economic environment, technological advances, and changes in cost structure. Details of purchased intangible assets were as follows (in thousands): As of September 25, 2015 As of December 26, 2014 Gross Gross Carrying Accumulated Carrying Carrying Accumulated Carrying Useful Life Amount Amortization Value Amount Amortization Value (in years) AIT Customer relationships $ 19,000 $ (14,726 ) $ 4,274 $ 19,000 $ (13,011 ) $ 5,989 7 Tradename 1,900 (1,304 ) 596 1,900 (1,081 ) 819 6 Intellectual property/know-how 1,600 (743 ) 857 1,600 (571 ) 1,029 7 Marchi Customer relationships 9,900 (660 ) 9,240 — — — 10 Tradename 1,170 (158 ) 1,012 — — — 6 Intellectual property/know-how 12,300 (919 ) 11,381 — — — 8-12 Miconex Customer relationships 8,800 (195 ) 8,605 — — — 7.5 UCT Tradename 8,987 — 8,987 8,987 — 8,987 * Total $ 63,657 $ (18,705 ) $ 44,952 $ 31,487 $ (14,663 ) $ 16,824 * The Company concluded that the UCT tradename intangible asset life is indefinite and is therefore not amortized but is reviewed for impairment at least annually and whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. The Company amortizes its tradenames for AIT and Marchi and customer relationships intangible asset for AIT using an accelerated method over the estimated economic life of the assets, ranging from 6 to 7 years. The Company amortizes its intellectual property/know-how and customer relationships intangible assets for Marchi and Miconex on a straight-line basis with an estimated economic life of the assets ranging from 7 to 12 years. Amortization expense was approximately $1.6 million and $1.2 million for the three months ended September 25, 2015 and September 26, 2014, respectively and $4.0 million and $3.7 million for the nine months ended September 25, 2015 and September 26, 2014, respectively. Amortization expense is charged to general and administrative. As of September 25, 2015, future estimated amortization expense is expected to be as follows (in thousands): Amortization Expense 2015 (remaining in year) $ 1,648 2016 6,062 2017 5,142 2018 4,582 2019 4,210 Thereafter 14,321 Total $ 35,965 |

Borrowing Arrangements | 6. Borrowing Arrangements Prior to February 5, 2015, the Company had borrowing arrangements with Silicon Valley Bank under a Loan and Security Agreement (the “Loan Agreement”) which included a $40.0 million revolving credit facility (the “Revolver”), maturing on July 3, 2016, and a $40.0 million term loan (the “Term Loan”), maturing on July 3, 2016. The interest rate on the Revolver during the month of January 2015 was 3.75%. On February 2, 2015, the Company entered into a new credit agreement (the “Credit Agreement”) by and among the Company, certain of its subsidiaries and East West Bank and City National Bank (collectively, the “Lenders”). The new credit agreement was amended on April 3, 2015 (as amended, the “Credit Agreement”) to modify certain terms of the agreement. The Credit Agreement provides for a term loan in an aggregate principal amount of $40.0 million (the “New Term Loan”) and a revolving credit facility in an aggregate principal amount of $40.0 million (the “New Revolving Credit Facility”), a letter of credit facility in the aggregate availability amount of $20.0 million (as a sublimit of such New Revolving Credit Facility) (the “L/C Facility”) and a swingline sub-facility in the aggregate availability amount of $5.0 million (as a sublimit of the New Revolving Credit Facility) (together with the Term Loan, the Revolving Credit Facility and the L/C Facility, the “Senior Secured Credit Facility”). On February 2, 2015, the Company borrowed an aggregate of $40.0 million under the New Term Loan and approximately $6.5 million under the New Revolving Credit Facility. The borrowed funds were used to repay the outstanding balance to Silicon Valley Bank as lender under our prior Loan Agreement. The prior Loan Agreement was terminated in connection with this transaction and, as a result, the outstanding balance of the revolver of $31.3 million was classified as long-term debt as of December 26, 2014 in accordance with the terms of the new debt agreement. In addition, the Company expensed the unamortized debt issuance costs of approximately $0.7 million in the first quarter of 2015. On February 5, 2015, in order to finance the acquisition of Marchi, the Company borrowed $29.7 million under the New Revolving Credit Facility. The New Term Loan must be repaid in consecutive quarterly installments of $1.25 million for the first four installments and $2.9 million for the remaining twelve installments, with the first payment made on March 31, 2015, and with the balance of the outstanding principal amount of the New Term Loan due at the final maturity, which is February 2, 2019. The New Revolving Credit Facility is available for the four-year period beginning on February 2, 2015. The Credit Agreement includes customary representations, warranties, covenants and events of default. The Company and certain of its subsidiaries have agreed to secure all of their obligations under the Credit Agreement by granting a first priority lien in substantially all of their respective personal property assets (subject to certain exceptions and limitations). At the Company’s option, borrowings under the New Term Loan and New Revolving Credit Facility (subject to certain limitations) bear interest at either a base rate or at the London Interbank Offered Rate (“LIBOR”) (with the LIBOR being adjusted for certain Eurocurrency reserve requirements, if any, as described in the Credit Agreement), plus, in each case, an applicable margin based on the Company’s consolidated leverage ratio. All loans described above made on February 2, 2015 were initially base rate loans, carrying interest of 3.25%. The effective interest rate will be higher due to the incurrence of certain loan-related costs of $0.6 million that have been treated as a discount on the debt and amortized over the life of the loan. As of September 25, 2015, the interest rates on the outstanding New Term Loan and New Revolving Credit facility were 2.70% (2.5% fixed and 0.2% variable based on LIBOR) and 3.0% fixed, respectively. In order to manage interest rate risk on the variable component of the New Term Loan the Company entered into an interest rate swap with the Lenders in September 2015 with a total notional amount of $20.0 million pursuant to which the Company pays the counterparty a fixed rate of 0.99% and receives interest at a variable rate equal to the LIBOR rate the Company is required to pay under its New Term Loan, or 0.2%, as of September 25, 2015. This interest rate swap effectively locks in a fixed interest rate of 3.49% on $20.0 million of the $37.5 million term loan balance outstanding as of September 25, 2015, with a decreasing notional amount based on prorated quarterly principal payments over the remaining period of the term loan. The Credit Agreement requires the Company to maintain certain financial covenants including a consolidated fixed charge coverage ratio (as defined in the Credit Agreement) of at least 1.25 to 1.00 starting with the end of the first quarter of fiscal 2015 and a consolidated leverage ratio (as defined in the Credit Agreement) no greater than 3.5 to 1.00 starting with the end of the first quarter of fiscal 2015. The Credit Agreement also includes other customary affirmative and negative covenants. The Company was in compliance with all covenants for the quarter ended September 25, 2015. The Credit Agreement also contains provisions requiring the following mandatory prepayments (subject to certain exceptions and limitations): annual prepayments in an amount equal to (a) 33% of excess cash flow (as defined in the Credit Agreement) if the aggregate outstanding principal amount of the New Term Loan equals or exceeds $20.0 million and (b) 25% of excess cash flow if the aggregate outstanding principal amount of the New Term Loan equals or exceeds $10.0 million but is less than $20.0 million. The Credit Agreement also restricts us from declaring or paying any cash dividends. The fair value of the Company’s long term debt was based on Level 2 inputs, and fair value was determined using quoted prices for similar liabilities in inactive markets. The fair value of the Company’s outstanding borrowings under the Company’s revolving credit facility was based on Level 2 inputs, and fair value was determined using inputs other than quoted prices that are observable, specifically, discounted cash flows of expected payments at current borrowing rates. The Company’s carrying value approximates fair value for the Company’s long term debt and revolving credit facility. As of September 25, 2015, the outstanding amounts under the Company’s New Term Loan and New Revolving Credit Facility were $37.5 million and $36.2 million, respectively, which are gross of unamortized debt issuance costs of $0.5 million for a total of $73.2 million. In addition to the New Term Loan and New Revolving loan, the Company has $3.7 million of bank debt from the acquired company, Miconex, with interest rates ranges from 1.3% to 10.5% and due dates from 2015 to 2020. As of September 25, 2015, our total bank debt was $76.9 million. |

Income Tax Disclosure [Abstract] | |
Income Tax | 7. Income Tax The Company’s income tax provision and effective tax rate for the three and nine month periods ended September 25, 2015 were $ 0.6 million and 27.8% and $2.0 million and 28.6%, respectively compared to $0.9 million and 19.6% and $3.9 million and 33.3%, respectively for the three and nine month periods ended September 26, 2014. The change in respective rates reflects, primarily, changes in the geographic mix of worldwide earnings and financial results, as well as the impact of losses which have a full valuation allowance for the three and nine month periods ended September 25, 2015 compared to the three and nine month periods ended September 26, 2014. Our effective tax rates were lower than the statutory rates for the first nine months of 2015 and 2014 primarily due to the geographic distribution of our world-wide earnings in foreign jurisdictions with lower tax rates or tax holidays, such as the tax holiday we are currently enjoying in Singapore. Company management continuously evaluates the need for a valuation allowance and as of September 25, 2015, concluded that a full valuation allowance on its California, Oregon, and one of its Chinese subsidiaries was still appropriate. The Company earns a significant amount of its operating income outside the United States, which is deemed to be indefinitely reinvested in foreign jurisdictions. As a result, most of the Company’s cash and cash equivalents are held by foreign subsidiaries. The Company currently does not intend nor foresee a need to repatriate these funds to the U.S. The Company expects existing domestic cash and cash flows from operations to continue to be sufficient to fund its domestic operating activities and cash commitments for investing and financing activities, such as debt repayment and capital expenditures, for at least the next 12 months and thereafter for the foreseeable future. If the Company should require more capital in the U.S. than is generated by its domestic operations, for example to fund significant discretionary activities such as business acquisitions, the Company could elect to repatriate future earnings from foreign jurisdictions or raise capital in the United States through debt or equity issuances. These alternatives could result in higher effective tax rates, increased interest expense, or dilution of our earnings. The Company has borrowed funds domestically and continues to believe it has the ability to do so at reasonable interest rates. The Company does not provide for U.S. taxes on its undistributed earnings of foreign subsidiaries that it intends to invest indefinitely outside the U.S., unless such taxes are otherwise required under U.S. tax law. In 2014, the Company determined that a portion of the current year earnings of one of its China subsidiaries may be remitted in the future to one of its foreign subsidiaries outside of mainland China and, accordingly, the Company provided for the related withholding taxes in its consolidated financial statements. If the Company changes its intent to reinvest its undistributed foreign earnings indefinitely or if a greater amount of undistributed earnings are needed than the previous anticipated remaining unremitted foreign earnings, the Company could be required to accrue or pay U.S. taxes on some or all of these undistributed earnings. As of September 25, 2015, the Company had undistributed earnings of foreign subsidiaries that are indefinitely invested outside of the U.S. of approximately $64.5 million. It is not practicable to determine the income tax liability that might be incurred if these earnings were to be distributed. The following table summarizes the activity related to the Company’s unrecognized tax benefits (in thousands): Nine months ended September 25, September 26, 2015 2014 Balance as of the beginning of period $ 356 $ 165 Increase (decrease) related to current year tax positions (26 ) 180 Balance as of the end of period $ 330 $ 345 The Company’s gross liability for unrecognized tax benefits as of September 25, 2015 and December 26, 2014 was $0.3 million and $0.3 million, respectively. Increases or decreases to interest and penalties on uncertain tax positions are included in the income tax provision in the condensed consolidated statements of operations. Interest related to uncertain tax positions was immaterial for each of the three and six month periods ended September 25, 2015 and September 26, 2014. Although it is possible some of the unrecognized tax benefits could be settled within the next twelve months, the Company cannot reasonably estimate the outcome at this time. The determination of the Company’s tax provision is subject to judgments and estimates. The carrying value of the Company’s net deferred tax assets, which is made up primarily of tax deductions and net operating loss carryforwards, assumes the Company will be able to generate sufficient future income to fully realize the income tax benefit. In determining whether the realization of these deferred tax assets may be impaired, the Company makes judgments with respect to whether the Company is likely to generate sufficient future taxable income to realize these assets. In addition, the calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. Resolution of these uncertainties in a manner inconsistent with the Company’s expectations could have a material impact on the Company’s results of operations and financial position. The Company files income tax returns in the U.S. federal jurisdiction, various states and foreign jurisdictions. The Company’s 2012 through 2014 federal income tax returns are open to audit through the statute of limitations by the Internal Revenue Service. The Company’s 2010 through 2014 state income tax returns are open to audit by the California Franchise Tax Board. The Company is also subject to examination in various other jurisdictions for various periods. The Company is currently enjoying a zero rate tax holiday related to its Singapore subsidiary that will expire for tax years beginning January 2016. This tax rate is subject to achieving certain commitments agreed to with the Economic Development Board of Singapore including investment and employment thresholds. The Company’s Singapore subsidiary recorded a net profit of $1.7 million and $6.2 million for the three and nine month periods ended September 25, 2015, respectively. |

Earnings Per Share [Abstract] | |
Net Income Per Share | 8. Net Income Per Share Basic net income per share excludes dilution and is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted net income per share reflects the potential dilution that would occur if outstanding securities or other contracts to issue common stock were exercised or converted into common stock. The following is a reconciliation of the numerators and denominators used in computing basic and diluted net income per share (in thousands, except per share data): Three months ended Nine months ended September 25, September 26, September 25, September 26, 2015 2014 2015 2014 Numerator: Net income (loss) $ 1,676 $ (5,262 ) $ 5,056 $ 7,825 Denominator: Shares used in computation — basic: Weighted average common shares outstanding 31,993 29,477 31,359 29,242 Shares used in computation — diluted: Shares used in computing basic net income per share 31,993 29,477 31,359 29,242 Dilutive effect of common shares outstanding subject to repurchase 110 — 222 261 Dilutive effect of options outstanding 52 — 72 409 Weighted average shares used in computing diluted net income per share 32,155 29,477 31,653 29,912 Net income (loss) per share — basic $ 0.05 $ (0.18 ) $ 0.16 $ 0.27 Net income (loss) per share — diluted $ 0.05 $ (0.18 ) $ 0.16 $ 0.26 The Company had securities outstanding which could potentially dilute basic net income per share in the future, but the incremental shares from the assumed exercise of these securities were excluded in the computation of diluted net income per share, as their effect would have been anti-dilutive. Such outstanding securities consisted of 204,154 and 281,507 stock options for the three and nine month periods ended September 25, 2015, respectively. For the three months period ended September 26, 2014, all potentially dilutive securities outstanding were considered anti-dilutive, and therefore the calculation of basic and diluted net loss per share was the same and 268,706 stock options for the nine months period ended September 26, 2014 was excluded as their effect would have been anti-dilutive. |

Fair Value of Measurements | Fair Value of Measurements — Level 1 — Observable inputs that reflect quoted prices (unadjusted) for identical assets or liabilities in active markets. Level 2 — Inputs that are based upon quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-based valuation techniques for which all significant inputs are observable in the market or can be derived from observable market data. Where applicable, these models project future cash flows and discount the future amounts to a present value using market-based observable inputs including interest rate curves, foreign exchange rates, and credit ratings. Level 3 — Unobservable inputs that are supported by little or no market activities. The fair value hierarchy requires an entity to maximize the use of observable inputs and minimize the use of unobservable inputs when measuring fair value. |
Derivative Financial Instruments | Derivative Financial Instruments |
Inventories | Inventories Inventory write downs inherently involve judgments as to assumptions about expected future demand and the impact of market conditions on those assumptions. Although the Company believes that the assumptions it used in estimating inventory write downs are reasonable, significant changes in any one of the assumptions in the future could produce a significantly different result. There can be no assurances that future events and changing market conditions will not result in significant increases in inventory write downs. |

Income Taxes | Income Taxes The Company continued to maintain a full valuation allowance on its California, Oregon, and one of its Chinese subsidiaries deferred tax amounts as of September 25, 2015 totaling $3.2 million. Income tax positions must meet a more likely than not recognition threshold to be recognized. Income tax positions that previously failed to meet the more likely than not threshold are recognized in the first subsequent financial reporting period in which that threshold is met. Previously recognized tax positions that no longer meet the more likely than not threshold are derecognized in the first subsequent financial reporting period in which that threshold is no longer met. The Company recognizes potential accrued interest and penalties related to unrecognized tax benefits within the consolidated statements of income as income tax expense. The calculation of tax liabilities involves significant judgment in estimating the impact of uncertainties in the application of complex tax laws. Resolution of these uncertainties in a manner inconsistent with the Company’s expectations could have a material impact on its results of operations and financial position. Management believes that it has adequately provided for any adjustments that may result from these examinations; however, the outcome of tax audits cannot be predicted with certainty. The determination of the Company’s tax provision is subject to judgments and estimates. |

Stock-Based Compensation Expense | Stock-Based Compensation Expense The Company maintains stock-based compensation plans which allow for the issuance of equity-based awards to executives, directors and certain employees. These equity-based awards include stock options, restricted stock awards (“RSAs”) and restricted stock units (“RSUs”) which can be either time-based or performance-based. The Company also maintains an employee stock purchase plan that provides for the issuance of shares to all eligible employees of the Company at a discounted price. Stock-based compensation expense includes compensation costs related to estimated fair values of stock options and awards granted. The estimated fair value of the Company’s equity-based awards, net of expected forfeitures, is amortized on a straightline basis over the awards’ vesting period, typically four years for stock options, three years for RSUs and one year for RSAs, and is adjusted for subsequent changes in estimated forfeitures related to all equity-based awards and performance as it relates to performance-based RSUs. The Company applies the fair value recognition provisions based on the FASB’s guidance regarding stock-based compensation. The exercise price of each stock option equals the market price of the Company’s stock on the date of grant. Most options are scheduled to vest over four years and expire no later than ten years from the grant date. The fair value of each option grant is estimated on the date of grant using the Black-Scholes option pricing model. The determination of the fair value of share-based payment awards on the date of grant using an option-pricing model is affected by the Company’s stock price as well as assumptions regarding certain variables. These variables include the expected term of the awards; the Company’s expected stock price volatility over the term of the awards, actual and projected employee stock option exercise behaviors, the risk-free interest rate and expected dividends. The Company estimates the expected term of share-based awards granted based on the Company’s historical option term experience. The Company estimates the volatility of its common stock based upon the Company’s historical stock price volatility over the length of the expected term of the options. The Company bases the risk-free interest rate that it uses in the option valuation model on U.S. Treasury zero-coupon issues with remaining maturities similar to the expected term of the options. The Company does not anticipate paying any cash dividends in the foreseeable future and therefore uses an expected dividend yield of zero in the option valuation model. The Company is required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. The Company uses historical data to estimate pre-vesting option forfeitures and records share-based compensation expense only for those awards that are expected to vest. The Company also considers, each quarter, whether there have been any significant changes in facts and circumstances that would affect its estimated forfeiture rate. |
Stock Options | Stock Options Stock option activity for the nine months ended September 25, 2015: Shares Weighted Weighted Aggregate Outstanding at December 26, 2014 853,551 $ 8.87 1.35 $ 1,798 Granted — — Exercised (339,303 ) $ 6.48 Canceled (197,600 ) $ 11.18 Outstanding at September 25, 2015 316,648 $ 10.01 2.31 $ 234,133 Options exercisable at September 25, 2015 316,648 $ 10.01 2.31 $ 234,133 There were no options granted by the Company during either of the nine month periods ended September 25, 2015 and September 26, 2014. As of September 25, 2015, there was no stock-based compensation expense attributable to stock options as all outstanding options were fully vested. |
Employee Stock Purchase Plan | Employee Stock Purchase Plan The Company also maintains an employee stock purchase plan (“ESPP”) that provides for the issuance of shares to all eligible employees of the Company at a discounted price. Under the ESPP, substantially all employees may purchase the Company’s common stock through payroll deductions at a price equal to 95 percent of the fair market value of the Company’s stock at the end of each applicable purchase period. |
Restricted Stock Units and Restricted Stock Awards | Restricted Stock Units and Restricted Stock Awards The Company grants RSUs to employees and RSAs to non-employee directors as part of the Company’s long term equity compensation plan. Restricted Stock Units During the quarter ended March 27, 2015, the Company granted 456,500 RSU’s, with a weighted average fair value of $8.68 per share, and granted 90,500 performance stock units with a weighted average fair value of $8.35 per share. During the quarter ended June 26, 2015, the Company granted 134,000 RSU’s, with a weighted average fair value of $6.53 per share. The Company granted 103,500 RSU’s with a weighted average fair value of $6.71 per share during the quarter ended September 25, 2015. During the nine months ended September 25, 2015, 39,938 vested shares were withheld to satisfy withholding tax obligations, resulting in the net issuance of 337,443 shares. As of September 25, 2015, approximately $ 6.8 million of stock-based compensation cost, net of estimated forfeitures, related to RSU’s remains to be amortized over a weighted average period of 2.1 years. As of September 25, 2015, a total of 1,277,741 RSU’s remain outstanding with an aggregate fair value of $6.8 million and a weighted average remaining contractual term of 1.3 years.

Recent Accounting Pronouncements | Recent Accounting Pronouncements In September 2015, the Financial Accounting Standards Board (FASB) issued updated guidance on the accounting for purchase accounting adjustments determined during the measurement period (i.e. up to one year after the acquisition). The new guidance requires an acquirer to recognize such adjustments in the reporting period in which the adjustment amounts are determined. Previously, such adjustments were required to be recorded on a retrospective basis. The Company has elected to early adopt this guidance beginning in the third quarter 2015 on a prospective basis. The adoption of this guidance did not have a significant impact on the condensed consolidated financial statements. In July 2015, the FASB issued authoritative guidance that requires inventory to be measured at the lower of cost and net realizable value instead of at lower of cost or market. This guidance does not apply to inventory that is measured using last-in, first out (LIFO) or the retail inventory method but applies to all other inventory including those measured using first-in, first-out (FIFO) or the average cost method. The authoritative guidance will be effective for the Company in the first quarter of fiscal 2018 and should be applied prospectively. Early adoption is permitted as of the beginning of an interim or annual reporting period. The Company is currently evaluating the effect of this new guidance on the Company’s consolidated financial statements. In April 2015, the FASB issued authoritative guidance that requires debt issuance costs to be presented in the balance sheet as a direct deduction from the carrying amount of the related debt liability, consistent with debt discounts. The authoritative guidance is effective for the Company in the first quarter of fiscal 2017 and should be applied retrospectively. Early adoption is permitted. The adoption of this guidance is not expected to have a significant impact on the Company’s consolidated financial statements. |
