Accounting Policies [Abstract]	'
Summary of Significant Accounting Policies	'
	(1)     SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
	NATURE OF OPERATIONS
	BTU International, Inc. and its wholly owned subsidiaries (the “Company”) are primarily engaged in the design, manufacture, sale, and service of thermal processing systems, which are used as capital equipment in various manufacturing processes, primarily in the electronics and alternative energy industries.
	COMPREHENSIVE INCOME (LOSS)
	The Company follows Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 220, Comprehensive Income (“ASC 220”) as amended by Accounting Standards Update (ASU) 2011-05, Presentation of Comprehensive Income. ASC 220 requires companies to report all changes in equity during a period, resulting from net income (loss) and transactions from non-owner sources, in a financial statement in the period in which they are recognized. On January 1, 2012, the date of adoption of ASU 2011-05, we had the option to report total comprehensive income, including components of net income and components of other comprehensive income, as a single continuous statement or in two separate but consecutive statements. We elected to present comprehensive income in two separate but consecutive statements as part of the consolidated financial statements. Other than a change in presentation, the implementation of this accounting pronouncement did not have a material impact on our consolidated financial statements.
	PRINCIPLES OF CONSOLIDATION AND THE USE OF ESTIMATES
	The accompanying consolidated financial statements include the accounts of the Company. All material inter-company balances and transactions have been eliminated in consolidation. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. The primary estimates used in the consolidated financial statements include the percentage of completion revenue method, inventory valuation, allowance for doubtful accounts, valuation of deferred income taxes, stock-based compensation and warranty reserves.
	CASH AND CASH EQUIVALENTS
	The Company has classified certain highly liquid financial instruments, with original maturities of three months or less, as cash equivalents.
	ACCOUNTS RECEIVABLE
	Accounts receivable are stated at the amount management expects to collect from outstanding balances. An allowance for doubtful accounts is provided for those accounts receivable considered to be uncollectible based upon historical experience and management’s evaluation of outstanding accounts receivable at the end of the year. Uncollectible accounts are written off against the allowance when identified. Bad debt expense (recovery) was ($280,000), $1,345,000, and ($49,000) for 2013, 2012 and 2011, respectively.
	INVENTORIES
	Our inventories consist of material, labor and manufacturing overhead costs. We determine the cost of inventory based on a first-in, first-out method. We regularly review the quantity of inventories on hand and compare these quantities to the expected usage of each applicable product or product line. Our inventories are adjusted in value to the lower of cost or net realizable value and a new cost basis is established. Since the value of our inventories depends in part on our estimates of each product’s net realizable value, adjustments may be needed to reflect changes in valuation. Any adjustments we are required to make to lower the value of the inventories are recorded as a charge to cost of sales.
	Inventories consist of the following (in thousands):
		Years Ended December 31,
		2013		2012
	Raw materials and manufactured components	$	6,010	$	4,772
	Work-in-process		2,459		1,905
	Finished goods		1,362		2,870
	Total inventory	$	9,831	$	9,547
	The Company recorded inventory write-downs of $1,868,000, $5,261,000, and $2,294,000, for the years ended 2013, 2012 and 2011, respectively. The write-downs recorded are net of recoveries of sold inventory that had previously been written-down in the amounts of approximately $250,000, $60,000, and $485,000 for the years ended 2013, 2012 and 2011, respectively.
	PROPERTY, PLANT AND EQUIPMENT
	The Company provides for depreciation using the straight-line method over the assets’ useful lives. Leasehold improvements are amortized on a straight-line basis over the lesser of the estimated useful life of the asset or the lease term. The estimated useful lives for depreciation purposes are as follows:
	Buildings and improvements		8-25 years
	Machinery and equipment		2-8 years
	Software		3-10 years
	Furniture and fixtures		3-8 years
	Leasehold improvements		3 years
	Depreciation expense was approximately $1,603,000, $1,641,000, and $1,624,000 for the years ended December 31, 2013, 2012, and 2011, respectively.
	Maintenance and repairs are charged to operations as incurred. When equipment and improvements are sold or otherwise disposed of, the asset cost and accumulated depreciation are removed from the accounts, and the resulting gain or loss, if any, is included in the results of operations.
	The Company evaluates long-lived assets such as intangible assets and property, plant and equipment under FASB ASC 360-10-35-15, Impairment or Disposal of Long-Lived Assets. This statement requires that long-lived assets and certain identifiable intangibles are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset or asset group to future undiscounted net cash flows expected to be generated by the asset or asset group. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. No impairment of long-lived assets were identified during the years ended December 31, 2013, 2012 and 2011.
	OTHER ASSETS
	Other assets consist of the following (in thousands):
		2013		2012
	Deferred financing costs, net of amortization	$	73	$	23
	Intellectual property, net of amortization		—		23
	Deferred tax asset—non-current		—		143
	Long term assets		553		292
	Total	$	626	$	481
	Deferred financing costs, capitalized in 2013, are being amortized over ten years, the term of the mortgage note. Amortization on deferred financing costs was approximately $7,000, $7,000 and $7,000 in 2013, 2012 and 2011, respectively. Amortization on intellectual property was approximately $23,000, $54,000, and $169,000 in 2013, 2012 and 2011, respectively.
	INCOME TAXES
	Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been included in the consolidated financial statements or tax returns. The amounts of deferred tax assets or liabilities are based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided if, based on the weight of the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.
	We assess tax positions taken on tax returns, including recognition of potential interest and penalties, in accordance with the recognition thresholds and measurement attributes outlined in ASC 740. Interest and penalties recognized, if any, would be classified as a component of income tax expense.
	TRANSLATION OF FOREIGN CURRENCIES
	Assets and liabilities of the Company’s foreign operations are translated from their functional currency into U.S. dollars at year end exchange rates. Revenue and expense items are translated at weighted average rates of exchange prevailing during the year. Gains and losses arising from translation are accumulated as a separate component of stockholders’ equity, as the functional currency of the subsidiaries is their local currency, and the reporting currency of the Company is the U.S. dollar. Exchange gains and losses arising from transactions denominated in foreign currencies are included in income as incurred.
	PATENTS
	The Company has patents in the U.S. and certain foreign countries for some of its products and processes. No value has been assigned to these patents in the accompanying consolidated financial statements.
	REVENUE RECOGNITION
	The Company recognizes revenue in accordance with FASB ASC Topic 605, Revenue Recognition (“ASC 605”). Under these guidelines, revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred or services rendered, the price is fixed or determinable and payment is reasonably assured. Under these requirements, when the terms of sale include customer acceptance provisions, and compliance with those provisions has not been demonstrated, revenues are recognized upon acceptance.
	Applying the requirements of ASC 605 to future sales arrangements used in the Company’s equipment sales may result in the deferral of the revenue for some equipment sales. Products shipped to customers that do not meet the threshold requirements for revenue recognition as outlined above remain in the Company’s inventory on the Consolidated Balance Sheet until revenue is recognized. Any cash collected from customers for products for which revenue has been deferred is recorded as Deferred Revenue on the Consolidated Balance Sheet.
	The Company also has certain sales transactions for products, which are not completed within the normal operating cycle of the business. It is the Company’s policy to account for these transactions using the percentage of completion method for revenue recognition purposes when all of the following criteria exist: (1) The Company has received the customer’s purchase order or entered into a legally binding contract, (2) The customer is credit worthy and collection is probable or customer prepayments are required at product completion milestones or specific dates, (3) The sales value of the product to be delivered is significant in amount when compared to the Company’s other products, and (4) Product costs can be reasonably estimated, there is no major technological uncertainty and the total engineering, material procurement, product assembly and test cycle time extend over a period of six months or longer.
	Under the percentage of completion method, revenues and gross margins to date are recognized based upon the ratio of costs incurred to date compared to the latest estimate of total costs to complete the product as a percentage of the total contract revenue for the product. Revisions in costs and gross margin percentage estimates are reflected in the period in which the facts causing the revision become known. Provisions for total estimated losses on uncompleted contracts, if any, are made in the period in which such losses are determined. For the years ended December 31, 2013, 2012 and 2011, $0, $1,731,686, and $2,406,714, respectively, were recognized as revenue using the percentage of completion method.
	The Company accounts for shipping and handling costs billed to customers in accordance with FASB ASC 605-45, Shipping and Handling Fees and Costs. Amounts billed to customers for shipping and handling costs are recorded as revenues with the associated costs reported as cost of goods sold.
	RESEARCH, DEVELOPMENT AND ENGINEERING
	Research, development and engineering costs are charged to expense as incurred.
	EARNINGS PER SHARE INFORMATION
	Basic earnings per share (EPS) is computed by dividing net income (loss) available to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted EPS is computed using the weighted-average number of common and potentially dilutive securities outstanding during the period, using the treasury stock method. Potentially dilutive securities include outstanding stock options and unvested restricted stock units (RSUs). Due to their antidilutive effect, approximately 1,454,292, 1,376,041, and 1,299,358 options to purchase common stock were excluded from the calculation of diluted loss per share for the years ended December 31, 2013, 2012 and 2011, respectively. However, these potentially dilutive securities could become dilutive in future periods.
	The weighted average number of common shares used to compute basic and diluted earnings per share consists of the following classification:
		Years Ended December 31,
		2013		2012		2011
		(In thousands)
	Basic shares		9,539		9,509		9,434
	Effect of dilutive options		—		—		—
Diluted shares		9,539		9,509		9,434
RECENT ACCOUNTING PRONOUNCEMENTS
In February 2013, the FASB issued ASU No. 2013-02, Reporting of Amounts Reclassified out of Accumulated Other Comprehensive Income, that requires entities to disclose items reclassified out of accumulated other Comprehensive Income (AOCI) and into net income in their entirety, the effect of the reclassification on each affected net income line item and for AOCI reclassification items that are not reclassified in their entirety into net income, a cross reference to other required U.S. GAAP disclosures. This consolidated standard is effective for annual periods beginning after December 15, 2012 and interim periods within those years. The application of this standard did not have material impact on the Company’s consolidated financial statements.
SUBSEQUENT EVENTS
For the fiscal year ended December 31, 2013, the Company has evaluated subsequent events for potential recognition and disclosure in the financial statements through the date these financial statements were filed with the Securities and Exchange Commission.

		$	6,361		$	5,147
	Warranties
	The Company provides standard warranty coverage for parts and labor for 12 months and special extended material-only coverage on certain other products. The Company estimates and records a reserve for anticipated warranty claims based on historical warranty claims as a percentage of revenue by product line. The reserve for warranty covers the estimated costs of material, labor and travel. Actual warranty claims incurred are charged against the reserve. Factors that affect the Company’s product warranty liability include the number of installed units, the anticipated cost of warranty repairs and historical and anticipated rates of warranty claims.
	The following table reflects changes in the Company’s accrued warranty account during the fiscal years ended December 31, 2013 and 2012:
		2013			2012
		(In thousands)
	Beginning balance	$	393		$	497
	Plus: accruals related to new sales		397			538
	Less: warranty claims incurred		(411	)		(642	)
	Ending balance	$	379		$	393
	Restructuring
	Costs associated with restructuring activities are accounted for in accordance with ASC Topic 420, Exit or Disposal Cost Obligations, or ASC Topic 712, Compensation—Nonretirement Postemployment Benefits, as applicable. Pursuant to ASC Topic 712, liabilities for employee severance are recorded when payment of severance is considered probable and the amount is estimable. For restructuring costs other than employee severance accounted under ASC Topic 712, a liability is recognized in accordance with ASC Topic 420 only when incurred.
	In April 2013, the Company eliminated 12 positions. Accordingly, the Company recorded a restructuring charge of $176,000 in the three months ended June 30, 2013. The decision to eliminate 12 positions was taken due to the continued slowdown in the solar industry. The Company eliminated 31 and 17 positions and recorded restructuring charges of $424,000 and $401,000 in the years ended December 31, 2012 and December 31, 2011.
	The restructuring charges were primarily severance and benefits.

	On March 30, 2006, the Company entered into a $10 million mortgage note secured by its real property in Billerica, Massachusetts, which had an initial maturity date of December 23, 2015. On September 9, 2010, the Company signed a First Loan Modification Agreement relating to the mortgage note, which reduced the annual interest rate from 6.84% to 5.50% and the monthly payment from $76,280 to $69,000.
	On August 31, 2009, the Company entered into a pledge and assignment agreement with a bank. The bank agrees, at the Company’s request, to issue letters of credit in the bank’s name and the Company agrees to cash collateralize letters of credit via restricted cash deposits at the bank. As of December 31, 2013 and 2012, the value of the outstanding letters of credit issued by the bank for the Company and cash collateralized by the Company was $247,515 and $247,090, respectively. This restricted cash value is included in the Company’s balance sheet in other current assets.
	On September 26, 2013, the Company signed a Second Loan Modification Agreement relating to the mortgage note, which extended the maturity date from December 23, 2015 to September 26, 2023. The modification also reduced the annual interest rate from 5.50% to 4.43% through September 26, 2018, at which time the interest rate will be adjusted to a per annum fixed rate equal to the aggregate of the Federal Home Loan Board (FHLB) Five Year Classic Advance Rate plus two hundred forty basis points. The current monthly payment was reduced from $69,000 to $57,997. The mortgage note had an outstanding balance on December 31, 2013 of approximately $7.6 million. All outstanding principal and accrued and unpaid interest will be due and payable on the maturity date.

	The Company has operating leases for its Shanghai manufacturing operations that allow extensions. As of December 31, 2013, the future minimum lease commitment for this facility is approximately $86,000. The Company has an operating lease for its UK facility that expires in May 2015. As of December 31, 2013, the future minimum lease commitment for this facility is approximately $54,000 payable through May 2015. As of December 31, 2013, the future minimum lease commitment for the Singapore and Malaysia office is approximately $43,000 and $11,000, respectively.
	Rent expense was approximately $421,000 in 2013, $390,000 in 2012 and $477,000 in 2011.
	As an equipment manufacturer, the Company generates and disposes of small quantities of solid waste that are considered hazardous under Environmental Protection Agency (“EPA”) regulations. Because the Company historically used a waste disposal firm that disposed of the solid waste at a site that the EPA has designated as a Superfund site, the Company has been named by the EPA as one of the entities responsible for a portion of the expected clean-up costs. Based on the Company’s proportional responsibility, as negotiated with and agreed to by the EPA, the Company’s liability related to this matter is $225,140. This amount is included in Accrued Expense on the Consolidated Balance Sheet as of December 31, 2013. On October 2, 2009, in accordance with the agreement, the Company established a letter of credit for $225,140 to the benefit of the EPA for potential cash payments as settlements for the Company’s proportional liability.

Concentration of Credit Risk and Significant Customers	'
	(5)     CONCENTRATION OF CREDIT RISK AND SIGNIFICANT CUSTOMERS
	The Company maintains the majority of its cash and cash equivalent balances with a small number of financial institutions who invest the funds in highly liquid financial instruments with terms not to exceed 90 days.
	The Company has international subsidiaries in China, the United Kingdom, Singapore and Malaysia. These subsidiaries transact business in their functional or local currency. Therefore, the Company is exposed to foreign currency exchange risks and fluctuations in foreign currencies, along with economic and political instability in the foreign countries in which it operates, all of which could adversely impact its results of operations and financial condition. The Company’s revenues are primarily derived from customers in the electronics and alternative energy manufacturing industries who are not required to provide collateral for amounts owed to the Company. The Company’s customers are dispersed over a wide geographic area and are subject to periodic review under the Company’s credit policies. The Company does not believe that it is subject to any unusual credit risks, other than the normal level of risk due to operating its business.
	Concentration of credit risk with respect to accounts receivable is limited to certain customers to whom the Company makes substantial sales. To reduce its credit risk, the Company routinely assesses the financial strength of its customers. The Company maintains an allowance for potential credit losses, but historically has not experienced any losses in excess of the loss allowance related to individual customers or groups of customers in any particular industry or geographic area.
	One customer accounted for $8.2 million or 17.4% of total net sales in 2013. One customer accounted for $7.3 million or 12.5% of total net sales and another customer accounted for $6.5 million or 11.2% of total net sales in 2012. One customer accounted for $11.9 million or 15.6% of total net sales and another accounted for $7.9 million or 10.4% of total net sales in 2011. As of December 31, 2013, one customer accounted for more than 10% of accounts receivable comprising 14.0% of the total. As of December 31, 2012, two customers accounted for more than 10% of accounts receivable comprising 22.5% of the total.

	The deferred tax valuation allowance increased by $3,893,000 and by $2,982,000 for the years ended December 31, 2013 and 2012, respectively. In assessing the realizability of deferred tax assets, the Company considers whether it is more likely than not that some portion or all of the deferred tax assets will be realized. The ultimate realization of deferred tax assets is dependent upon the generation of future taxable income during the periods in which those temporary differences become deductible. The Company considers the scheduled reversal of deferred tax liabilities, projected future income, and tax planning strategies in making this assessment. We have recorded a full valuation allowance against the U.S and China manufacturing subsidiary net deferred tax assets since we believe that, after considering all of the available objective evidence, both positive and negative, historical and prospective, with greater weight given to historical evidence, it is not more likely than not that these assets will be realized.
	The Company has federal net operating loss carryforwards of approximately $12,699,000 that expire between 2024 and 2033, $3,354,070 of which relates to excess tax deductions from share based payments, the tax benefit of which will be recorded as an increase in additional paid-in capital when the deduction reduces current taxes payable. The Company also has state net operating loss carryforwards of approximately $4,717,000 that expire between 2014 and 2033, $1,255,000 of the tax benefit will be recorded as an increase in additional paid-in-capital when the deduction reduces current taxes payable. The Company also has foreign tax credit carryforwards of approximately $2,941,000 that expire between 2018 and 2023, $253,265 of the tax benefit will be recorded as an increase in additional paid-in capital when the deduction reduces current taxes payable.
	Undistributed earnings of the Company’s foreign subsidiaries amounted to approximately $2.7 million at December 31, 2013. The Company’s historical and continuing policy is that its undistributed foreign earnings are indefinitely reinvested and, accordingly, no related provision for U.S. federal and state income taxes has been provided on the $2.7 million of undistributed foreign earnings. The amount of taxes attributable to these undistributed earnings is immaterial.
	The Company applies the provisions of FASB Interpretation No. 48 (“FIN 48”), “Accounting for Uncertainty in Income Taxes “, (now codified as FASB ASC 740, “Income Tax “). In this regard, an uncertain tax position represents the Company’s expected treatment of a tax position taken in a filed tax return, or planned to be taken in a future tax return, that has not been reflected in measuring income tax expense for financial reporting purposes.
	A reconciliation of the beginning and ending amount of our unrecognized tax benefits is summarized as follows:
		2013			2012			2011
	Balance at beginning of period		$151			$151		$	151
	Increase (decrease) related to current year tax positions		—			—			—
	Increase (decrease) related to prior year tax positions		-37			—			—
	Balance at end of period		$114			$151		$	151
	The unrecognized tax benefits at December 31, 2013, if recognized, would reduce the Company’s effective tax rate in the period recognized. For the year ended December 31, 2013, there were no material changes to the total amount of unrecognized tax benefits. We do not expect any significant increases or decreases for uncertain tax positions during the next 12 months.
	The Company’s major tax jurisdictions include the United States and China. The Company is no longer subject to U.S. state or local and non-U.S. income tax examinations by tax authorities in its major jurisdictions for years before 2007, except to the extent of net operating loss and tax credit carryforwards from those years. The Company’s policy is to recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense. There is no interest or penalties accrued at December 31, 2013.

	The Company has management incentive and profit sharing plans for its executives and all of its employees. These plans provide for bonuses upon the attainment of certain financial targets. Under these plans, $84,000, $70,000 and $217,000 was expensed in 2013, 2012 and 2011, respectively.
	The Company has a deferred 401(k) contribution plan that is available to cover all domestic employees of the Company. Subject to non-discriminatory restrictions on highly compensated employees, participants can voluntarily contribute a percentage of their compensation up to the plan limits, and the Company, at its discretion, may match this contribution up to a stipulated percentage. The Company’s expense under the plan was approximately $234,000, $269,000 and $321,000 for the years ended December 31, 2013, 2012 and 2011, respectively.

Disclosure Of Compensation Related Costs Sharebased Payments [Abstract]	'

	(8)     STOCK OPTION AND PURCHASE PLANS
	Stock Options
	The Company accounts for share-based compensation in accordance with the provisions of SFAS No. 123R, Share-Based Payment (now codified as FASB ASC Topic 718, Compensation—Stock Compensation (“ASC 718”)). This statement establishes standards for accounting for transactions in which an entity exchanges its equity instruments for goods or services. The Company’s stock option compensation expense was approximately $574,000, $808,000 and $1,234,000 for the years ended December 31, 2013, 2012 and 2011 respectively. These amounts do not include expense related to restricted stock awards or the employee stock purchase plan.
	The fair value of each option is estimated on the date of grant using the Black-Scholes option-pricing model. This model incorporates certain assumptions for inputs including a risk-free market interest rate, expected dividend yield of the underlying common stock, expected option life and expected volatility in the market value of the underlying common stock. The Company is also required to estimate forfeitures at the time of grant and revise those estimates in subsequent periods if actual forfeitures differ from those estimates. Historical data is used to estimate pre-vesting forfeitures and record stock-based compensation expense only for those awards that are expected to vest. Accordingly, awards ultimately expected to vest were reduced for annualized estimated forfeitures of 4% for each of the years ended December 31, 2013, 2012 and 2011. We used the following assumptions for options issued during the years ended December 31, 2013, 2012 and 2011, respectively:
	Calculation of Fair Values—Assumptions Used:	Dec. 31, 2013			Dec. 31, 2012			Dec. 31, 2011
	Expected Volatility		65.6	%		66.6	%		63.7	%
	Expected Life		4.19			4.15			4.64
	Risk-Free Interest Rate		0.92	%		0.57	%		1.23	%
	Expected Dividend Yield		0			0			0
	Expected volatilities are based on the weighted average historical volatility of the Company’s common stock for the expected life of the option. The Company has significant historical data to help evaluate the expected lives of options in developing its assumption. The risk-free interest rate is based upon quoted market yields for United States Treasury debt securities with a term approximating the expected life of the options. The expected dividend yield is based upon the Company’s history of having never issued a dividend and management’s current expectation of future action surrounding dividends.
	The Company has two stock option plans for employees, the 1993 Equity Incentive Plan (“1993 Plan”), which expired in 2003 with 254,791 unissued options, and the 2003 Equity Incentive Plan (“2003 Plan”). These plans allow for the award of stock and stock options to employees, directors and consultants. Under the terms of the plans, other stock awards can also be granted at the discretion of the Company’s board of directors. The Company also has two stock option plans for non-employee directors, the 1989 Stock Plan for Directors (“1989 Plan”), which expired in 2008 and the 1998 Stock Option Plan for Non-Employee Directors (“1998 Plan”). Under each plan, the exercise price of the options is not less than the fair market value at the date of the grant. Options expire from a minimum of two years to a maximum of ten years from the date of the grant. All new grants, for both employees and directors, are now issued from the same plan, the 2003 Plan.
	In May 2003, the shareholders approved the 2003 Plan, which allows for up to 700,000 shares to be awarded (plus the addition of up to 300,000 options that could be forfeited under the expired 1993 Plan). Also in May 2003, the shareholders approved an amendment to add 70,000 shares to the 1998 Plan.
	In May 2008, the shareholders approved an amendment to add 450,000 shares to the 2003 Plan. Also in May 2008, the shareholders approved an amendment to add 50,000 shares to the 1998 Plan.
	In May 2011, the shareholders approved an amendment to add 600,000 shares to the 2003 Plan.
	Shares available for future stock option and restricted stock unit grants, pursuant to the 2003 Plan and the 1998 Plan were 701,986 at December 31, 2013.
	A summary of all stock option activity for the years ended December 31, 2013, 2012 and 2011 is as follows:

	The aggregate intrinsic value of the outstanding options represents the total pre-tax intrinsic value, based on the Company’s closing stock price of $3.01 as of December 31, 2013 which would have been received by the option holders had all option holders exercised their options as of that date. As of December 31, 2013, there was $640,968 of total unrecognized compensation cost related to non-vested options granted under all of the Company’s option plans. That cost is expected to be recognized over a weighted average period of 1.39 years. The total fair value of shares vested during the year ended December 31, 2013 was $617,667.

Disclosures about the Fair Value of Financial Instruments	'
	(9)     DISCLOSURES ABOUT THE FAIR VALUE OF FINANCIAL INSTRUMENTS
	In accordance with the requirements of FASB ASC Topic 820, Fair Value Measurements and Disclosures (“ASC 820”) , the Company groups its financial assets and liabilities measured at fair value on a recurring basis in three levels, based on the markets in which the assets and liabilities are traded and the reliability of the assumptions used to determine fair value. These levels are:
		•	Level 1—Valuation is based upon quoted market price for identical instruments traded in active markets.
		•	Level 2—Valuation is based on quoted market 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 assumptions are observable in the market.
		•	Level 3—Valuation is generated from model-based techniques that use significant assumptions not observable in the market. Valuation techniques include use of discounted cash flow models and similar techniques.
	In accordance with the requirements of ASC 820, it is the Company’s policy to maximize the use of observable inputs and minimize the use of unobservable inputs when developing fair value measurements. When available, the Company uses quoted market prices to measure fair value. If market prices are not available, the fair value measurement is based on models that use primarily market based parameters including interest rate yield curves, option volatilities and currency rates. In certain cases where market rate assumptions are not available, the Company is required to make judgments about assumptions market participants would use to estimate the fair value of a financial instrument. Changes in the underlying assumptions used, including discount rates and estimates of future cash flows, could significantly affect the results of current or future values.
	At December 31, 2013 and 2012, the Company did not have any financial assets and liabilities that required being measured at fair value in accordance with ASC 820.
	The carrying amounts of the Company’s cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximate their fair value due to the instruments’ short-term nature. Long-term debt is also reported at carrying value and approximates fair value as the interest rate on the mortgage note payable of 4.43% approximates the current market interest rate.

Summary_of_Significant_Account1

Summary of Significant Accounting Policies (Policies)	12 Months Ended
	Dec. 31, 2013
Accounting Policies [Abstract]	'
Nature of Operations	'
	NATURE OF OPERATIONS
	BTU International, Inc. and its wholly owned subsidiaries (the “Company”) are primarily engaged in the design, manufacture, sale, and service of thermal processing systems, which are used as capital equipment in various manufacturing processes, primarily in the electronics and alternative energy industries.
Comprehensive Income (Loss)	'
	COMPREHENSIVE INCOME (LOSS)
	The Company follows Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) 220, Comprehensive Income (“ASC 220”) as amended by Accounting Standards Update (ASU) 2011-05, Presentation of Comprehensive Income. ASC 220 requires companies to report all changes in equity during a period, resulting from net income (loss) and transactions from non-owner sources, in a financial statement in the period in which they are recognized. On January 1, 2012, the date of adoption of ASU 2011-05, we had the option to report total comprehensive income, including components of net income and components of other comprehensive income, as a single continuous statement or in two separate but consecutive statements. We elected to present comprehensive income in two separate but consecutive statements as part of the consolidated financial statements. Other than a change in presentation, the implementation of this accounting pronouncement did not have a material impact on our consolidated financial statements.
Principles of Consolidation and the Use of Estimates	'
	PRINCIPLES OF CONSOLIDATION AND THE USE OF ESTIMATES
	The accompanying consolidated financial statements include the accounts of the Company. All material inter-company balances and transactions have been eliminated in consolidation. The preparation of financial statements in conformity with generally accepted accounting principles requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. The primary estimates used in the consolidated financial statements include the percentage of completion revenue method, inventory valuation, allowance for doubtful accounts, valuation of deferred income taxes, stock-based compensation and warranty reserves.
Cash and Cash Equivalents	'
	CASH AND CASH EQUIVALENTS
	The Company has classified certain highly liquid financial instruments, with original maturities of three months or less, as cash equivalents.
Accounts Receivable	'
	ACCOUNTS RECEIVABLE
	Accounts receivable are stated at the amount management expects to collect from outstanding balances. An allowance for doubtful accounts is provided for those accounts receivable considered to be uncollectible based upon historical experience and management’s evaluation of outstanding accounts receivable at the end of the year. Uncollectible accounts are written off against the allowance when identified. Bad debt expense (recovery) was ($280,000), $1,345,000, and ($49,000) for 2013, 2012 and 2011, respectively.
Inventories	'
	INVENTORIES
	Our inventories consist of material, labor and manufacturing overhead costs. We determine the cost of inventory based on a first-in, first-out method. We regularly review the quantity of inventories on hand and compare these quantities to the expected usage of each applicable product or product line. Our inventories are adjusted in value to the lower of cost or net realizable value and a new cost basis is established. Since the value of our inventories depends in part on our estimates of each product’s net realizable value, adjustments may be needed to reflect changes in valuation. Any adjustments we are required to make to lower the value of the inventories are recorded as a charge to cost of sales.
	Inventories consist of the following (in thousands):
		Years Ended December 31,
		2013		2012
	Raw materials and manufactured components	$	6,010	$	4,772
	Work-in-process		2,459		1,905
	Finished goods		1,362		2,870
	Total inventory	$	9,831	$	9,547
	The Company recorded inventory write-downs of $1,868,000, $5,261,000, and $2,294,000, for the years ended 2013, 2012 and 2011, respectively. The write-downs recorded are net of recoveries of sold inventory that had previously been written-down in the amounts of approximately $250,000, $60,000, and $485,000 for the years ended 2013, 2012 and 2011, respectively.
Property Plant and Equipment	'
	PROPERTY, PLANT AND EQUIPMENT
	The Company provides for depreciation using the straight-line method over the assets’ useful lives. Leasehold improvements are amortized on a straight-line basis over the lesser of the estimated useful life of the asset or the lease term. The estimated useful lives for depreciation purposes are as follows:
	Buildings and improvements		8-25 years
	Machinery and equipment		2-8 years
	Software		3-10 years
	Furniture and fixtures		3-8 years
	Leasehold improvements		3 years
	Depreciation expense was approximately $1,603,000, $1,641,000, and $1,624,000 for the years ended December 31, 2013, 2012, and 2011, respectively.
	Maintenance and repairs are charged to operations as incurred. When equipment and improvements are sold or otherwise disposed of, the asset cost and accumulated depreciation are removed from the accounts, and the resulting gain or loss, if any, is included in the results of operations.
	The Company evaluates long-lived assets such as intangible assets and property, plant and equipment under FASB ASC 360-10-35-15, Impairment or Disposal of Long-Lived Assets. This statement requires that long-lived assets and certain identifiable intangibles are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be recoverable. Recoverability of assets to be held and used is measured by a comparison of the carrying amount of an asset or asset group to future undiscounted net cash flows expected to be generated by the asset or asset group. If such assets are considered to be impaired, the impairment to be recognized is measured by the amount by which the carrying amount of the assets exceeds the fair value of the assets. No impairment of long-lived assets were identified during the years ended December 31, 2013, 2012 and 2011.
Other Assets	'
	OTHER ASSETS
	Other assets consist of the following (in thousands):
		2013		2012
	Deferred financing costs, net of amortization	$	73	$	23
	Intellectual property, net of amortization		—		23
	Deferred tax asset—non-current		—		143
	Long term assets		553		292
	Total	$	626	$	481
	Deferred financing costs, capitalized in 2013, are being amortized over ten years, the term of the mortgage note. Amortization on deferred financing costs was approximately $7,000, $7,000 and $7,000 in 2013, 2012 and 2011, respectively. Amortization on intellectual property was approximately $23,000, $54,000, and $169,000 in 2013, 2012 and 2011, respectively.
Income Taxes	'
	INCOME TAXES
	Deferred tax assets and liabilities are recognized for the expected future tax consequences of events that have been included in the consolidated financial statements or tax returns. The amounts of deferred tax assets or liabilities are based on the difference between the financial statement and tax basis of assets and liabilities using enacted tax rates in effect for the year in which the differences are expected to reverse. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A valuation allowance is provided if, based on the weight of the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.
	We assess tax positions taken on tax returns, including recognition of potential interest and penalties, in accordance with the recognition thresholds and measurement attributes outlined in ASC 740. Interest and penalties recognized, if any, would be classified as a component of income tax expense
Translation of Foreign Currencies	'
	TRANSLATION OF FOREIGN CURRENCIES
	Assets and liabilities of the Company’s foreign operations are translated from their functional currency into U.S. dollars at year end exchange rates. Revenue and expense items are translated at weighted average rates of exchange prevailing during the year. Gains and losses arising from translation are accumulated as a separate component of stockholders’ equity, as the functional currency of the subsidiaries is their local currency, and the reporting currency of the Company is the U.S. dollar. Exchange gains and losses arising from transactions denominated in foreign currencies are included in income as incurred.
Patents	'
	PATENTS
	The Company has patents in the U.S. and certain foreign countries for some of its products and processes. No value has been assigned to these patents in the accompanying consolidated financial statements.
Revenue Recognition	'
	REVENUE RECOGNITION
	The Company recognizes revenue in accordance with FASB ASC Topic 605, Revenue Recognition (“ASC 605”). Under these guidelines, revenue is recognized when persuasive evidence of an arrangement exists, delivery has occurred or services rendered, the price is fixed or determinable and payment is reasonably assured. Under these requirements, when the terms of sale include customer acceptance provisions, and compliance with those provisions has not been demonstrated, revenues are recognized upon acceptance.
	Applying the requirements of ASC 605 to future sales arrangements used in the Company’s equipment sales may result in the deferral of the revenue for some equipment sales. Products shipped to customers that do not meet the threshold requirements for revenue recognition as outlined above remain in the Company’s inventory on the Consolidated Balance Sheet until revenue is recognized. Any cash collected from customers for products for which revenue has been deferred is recorded as Deferred Revenue on the Consolidated Balance Sheet.
	The Company also has certain sales transactions for products, which are not completed within the normal operating cycle of the business. It is the Company’s policy to account for these transactions using the percentage of completion method for revenue recognition purposes when all of the following criteria exist: (1) The Company has received the customer’s purchase order or entered into a legally binding contract, (2) The customer is credit worthy and collection is probable or customer prepayments are required at product completion milestones or specific dates, (3) The sales value of the product to be delivered is significant in amount when compared to the Company’s other products, and (4) Product costs can be reasonably estimated, there is no major technological uncertainty and the total engineering, material procurement, product assembly and test cycle time extend over a period of six months or longer.
	Under the percentage of completion method, revenues and gross margins to date are recognized based upon the ratio of costs incurred to date compared to the latest estimate of total costs to complete the product as a percentage of the total contract revenue for the product. Revisions in costs and gross margin percentage estimates are reflected in the period in which the facts causing the revision become known. Provisions for total estimated losses on uncompleted contracts, if any, are made in the period in which such losses are determined. For the years ended December 31, 2013, 2012 and 2011, $0, $1,731,686, and $2,406,714, respectively, were recognized as revenue using the percentage of completion method.
	The Company accounts for shipping and handling costs billed to customers in accordance with FASB ASC 605-45, Shipping and Handling Fees and Costs. Amounts billed to customers for shipping and handling costs are recorded as revenues with the associated costs reported as cost of goods sold.
Research Development and Engineering	'
	RESEARCH, DEVELOPMENT AND ENGINEERING
	Research, development and engineering costs are charged to expense as incurred.
Earnings Per Share Information	'
	EARNINGS PER SHARE INFORMATION
	Basic earnings per share (EPS) is computed by dividing net income (loss) available to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted EPS is computed using the weighted-average number of common and potentially dilutive securities outstanding during the period, using the treasury stock method. Potentially dilutive securities include outstanding stock options and unvested restricted stock units (RSUs). Due to their antidilutive effect, approximately 1,454,292, 1,376,041, and 1,299,358 options to purchase common stock were excluded from the calculation of diluted loss per share for the years ended December 31, 2013, 2012 and 2011, respectively. However, these potentially dilutive securities could become dilutive in future periods.
	The weighted average number of common shares used to compute basic and diluted earnings per share consists of the following classification:
		Years Ended December 31,
		2013		2012		2011
		(In thousands)
	Basic shares		9,539		9,509		9,434
	Effect of dilutive options		—		—		—
	Diluted shares		9,539		9,509		9,434
Recent Accounting Pronouncements	'
	RECENT ACCOUNTING PRONOUNCEMENTS
	In February 2013, the FASB issued ASU No. 2013-02, Reporting of Amounts Reclassified out of Accumulated Other Comprehensive Income, that requires entities to disclose items reclassified out of accumulated other Comprehensive Income (AOCI) and into net income in their entirety, the effect of the reclassification on each affected net income line item and for AOCI reclassification items that are not reclassified in their entirety into net income, a cross reference to other required U.S. GAAP disclosures. This consolidated standard is effective for annual periods beginning after December 15, 2012 and interim periods within those years. The application of this standard did not have material impact on the Company’s consolidated financial statements.
Subsequent Events	'
	SUBSEQUENT EVENTS
	For the fiscal year ended December 31, 2013, the Company has evaluated subsequent events for potential recognition and disclosure in the financial statements through the date these financial statements were filed with the Securities and Exchange Commission.
