      Re:   Sanmina-SCI Corporation - Exchange of $750,000,000 of its
            Outstanding 10.375% Senior Secured Notes due January 15, 2010

Ladies and Gentlemen:

      We have acted as special counsel to the Alabama subsidiaries of
Sanmina-SCI Corporation, a Delaware corporation (the "Company"), named in
Schedule I hereto (the "Alabama Subsidiary Guarantors" and, together with the
Company and the additional subsidiary guarantors named on Schedule II hereto,
the "Registrants"), in connection with the filing by the Registrants with the
Securities and Exchange Commission (the "Commission") of a registration
statement on Form S-4 (the "Registration Statement") under the Securities Act of
1933, as amended (the "Securities Act"). The Alabama Subsidiary Guarantors and
the additional subsidiary guarantors are collectively referred to herein as the
"Subsidiary Guarantors." Pursuant to the Registration Statement, the Company is
registering under the Securities Act an aggregate of up to $750,000,000 in
principal amount of its 10.375% Senior Secured Notes due January 15, 2010 (the
"Exchange Notes") to be issued in exchange (the "Exchange Offer") for a like
principal amount of the Company's outstanding 10.375% Senior Secured Notes due
January 15, 2010 (the "Outstanding Notes") upon the terms set forth in the
Registration Statement and the letter of transmittal filed as an exhibit
thereto. The Outstanding Notes are guaranteed by each of the Subsidiary
Guarantors (each, an "Outstanding Guarantee" and collectively, the "Outstanding
Guarantees"). The Registration Statement also covers issuance of the guarantees
by each of the Subsidiary Guarantors of the Exchange Notes pursuant to the
Exchange Offer (the "Exchange Notes Guarantees" and, together with the
Outstanding

Guarantees, the "Guarantees"). The Exchange Notes and the Exchange Notes
Guarantees, to be issued pursuant to the Exchange Offer, are collectively
referred to herein as the "Securities." The Outstanding Notes and Outstanding
Guarantees were issued, and the Securities will be issued, pursuant to an
Indenture, dated as of December 23, 2002 (the "Indenture"), among the Company,
the Subsidiary Guarantors and U.S. Bank National Association (as successor to
State Street Bank and Trust Company of California, N.A.), as trustee (the
"Trustee").

      In rendering the opinions expressed below, we have examined originals or
copies of: (a) the Registration Statement, in the form filed with the
Commission; (b) the Exchange and Registration Rights Agreement, dated as of
December 23, 2002 (the "Registration Rights Agreement"), by and among the
Company, the Subsidiary Guarantors and the initial purchasers listed therein;
(c) the Indenture; (d) specimens of the certificates representing the Exchange
Notes and the Exchange Notes Guarantees, included as exhibits to the Indenture;
and (e) the other documents delivered by or on behalf of the Company, the
Subsidiary Guarantors and the Trustee as of the date hereof in connection with
the delivery of the Securities. We have also examined originals, or copies
identified to our satisfaction of such company records of the Alabama Subsidiary
Guarantors and other persons, and such other documents as we have deemed
necessary or appropriate as a basis for the opinions set forth below.

      We have assumed the following: (a) the authenticity of original documents
and the genuineness of all signatures; (b) the conformity to the originals of
all documents submitted to us as copies; (c) that the Indenture is a legal and
binding obligation of the Trustee and that the Exchange Notes will be duly
authenticated by the Trustee; and (d) the legal capacity of natural persons. As
to any facts material to the opinions expressed herein that were not
independently established or verified, we have relied upon oral or written
statements and representations of officers and other representatives of the
Company and the Subsidiary Guarantors.

      Our opinions are expressed only with respect to the laws of the State of
Alabama. We are not rendering any opinion as to compliance with any federal or
state law, rule or regulation relating to securities, or to the sale or issuance
thereof.

      On the basis of the foregoing and in reliance thereon and having regard
for legal considerations which we deem relevant, and subject to the limitations
and qualifications set forth herein, we advise you that in our opinion:

      1. Each Alabama Subsidiary Guarantor is duly formed and is validly
existing in good standing under the laws of the State of Alabama; and

      2. The Alabama Subsidiary Guarantors have duly authorized, executed and
delivered the Indenture; and

      3. The Alabama Subsidiary Guarantors have duly authorized their respective
Exchange Notes Guarantees; and

      4. Upon consummation of the Exchange Offer each Alabama Subsidiary
Guarantor will have the requisite corporate or company power to execute, deliver
and perform its obligations under the Exchange Notes Guarantees.

      We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to our firm under the caption "Legal
Matters" in the prospectus forming part of the Registration Statement and any
amendments thereto. Further, we consent to the reliance by Wilson Sonsini
Goodrich & Rosati on this letter in connection with their opinions regarding the
enforceability of the Exchange Notes Guarantees against the Alabama Subsidiary
Guarantors. This opinion letter speaks only at and as of its date and is based
solely on the facts and circumstances known to us at and as of such date.

                                                 Very truly yours,

                                                 LANIER FORD SHAVER & PAYNE P.C.
