The correct patent numbers to reference are 4312692 and 4314870.  Both
patents refer to the mechanical mounting of surface mount components using a
cured adhesive.

We are in the process of setting up a small assembly shop and would be
interested in the effects of the assertion of these patents.

        I tried to find these patents on the IBM Patent Server, but I found
        only non-SMT topics under these numbers.

        USP 4,812,692
        http://www.patents.ibm.com/details?patent_number=4812692:
        "Motor" (Mitsubishi)

        USP 4,814,870
        http://www.patents.ibm.com/details?patent_number=4814870:
        "Portable infrared imaging apparatus" (Comprix)

        None is from Matsushita, none is about SMT. I asked Mike C in the
        smtnet.com forum to provide more informations about these patents.
        Perhaps IPC could put the letter Mike C and Steve Gregory mentioned
        in this and/or the DesignerCouncil?
