                  Certification of Principal Executive Officer
            Pursuant to Section 302 of the Sarbanes-Oxley Act of 2002

  I, Leonard A. Rosenbaum, the principal executive officer of CVD Equipment
  Corporation, certify that:

       1. I have reviewed this quarterly report on Form 10-QSB  of  CVD
       Equipment Corporation;

       2. Based upon 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 upon 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 Exchange Act 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. Intentionally omitted.
            c. 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
            d. 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 the
       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.
