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?
