     CERTIFICATION OF CHIEF EXECUTIVE OFFICER PURSUANT TO SECTION 302(A) OF

                        THE SARBANES - OXLEY ACT OF 2002

I, Michael Cannon, certify that:

      1.    I have reviewed this quarterly report on Form 10-Q of Solectron
            Corporation;

      2.    Based on my knowledge, this report does not contain any untrue
            statement of a material fact or omit to state a material fact
            necessary to make the statements made, in light of the
            circumstances under which such statements were made, not
            misleading with respect to the period covered by this report;

      3.    Based on my knowledge, the financial statements, and other
            financial information included in this report, fairly present in
            all material respects the financial condition, results of
            operations and cash flows of the registrant as of, and for, the
            periods presented in this report;

      4.    The registrant's other certifying officer and I are responsible
            for establishing and maintaining disclosure controls and
            procedures (as defined in Securities Exchange Act of 1934 Rules
            13a-15(e) and 15d-15(e)) for the registrant and have:

            a)    Designed such disclosure controls and procedures, or caused
                  such disclosure controls and procedures to be designed
                  under our supervision, to ensure that material information
                  relating to the registrant, including its consolidated
                  subsidiaries, is made known to us by others within those
                  entities, particularly during the period in which this
                  report is being prepared;

            b)    Evaluated the effectiveness of the registrant's disclosure
                  controls and procedures and presented in this report our
                  conclusions about the effectiveness of the disclosure
                  controls and procedures, as of the end of the period
                  covered by this report based on such evaluation; and

            c)    Disclosed in this report any change in the registrant's
                  internal control over financial reporting that occurred
                  during the registrant's most recent fiscal quarter (the
                  registrant's fourth fiscal quarter in the case of an annual
                  report) that has materially affected, or is reasonably
                  likely to materially affect, the registrant's internal
                  control over financial reporting; and

      5.    The registrant's other certifying officer and I have disclosed,
            based on our most recent evaluation of internal control over
            financial reporting, to the registrant's auditors and the audit
            committee of registrant's board of directors (or persons
            performing the equivalent functions):

            a)    All significant deficiencies and material weaknesses in the
                  design or operation of internal control over financial
                  reporting which are reasonably likely to adversely affect the
                  registrant's ability to record, process, summarize and report
                  financial information; and

            b)    Any fraud, whether or not material, that involves management
                  or other employees who have a significant role in the
                  registrant's internal control over financial reporting.
