        Re: Sanmina Corporation (the "Company") Registration Statement on Form
S-3

Ladies and Gentlemen:

        We have examined the Registration Statement on Form S-3 to be filed with
the Securities and Exchange Commission (the "Registration Statement"), in
connection with the registration under the Securities Act of 1933, as amended,
of 1,990,354 shares of the Company's Common Stock. As your counsel, we have
examined the proceedings taken in connection with the sale and issuance of the
above-referenced securities.

        It is our opinion that the above-referenced securities, when issued and
sold in the manner referred to in the Registration Statement, will be legally
and validly issued, fully paid and nonassessable.

        We consent to the use of this opinion as an exhibit to the Registration
Statement, and further consent to the use of our name wherever appearing in the
Registration Statement, including the Prospectus constituting a part thereof,
and any amendment thereto.

                                              Very truly yours,

                                              WILSON SONSINI GOODRICH & ROSATI
                                              Professional Corporation
