 At a previous company I worked at we had a bonding machine
and we used a lot of EPROM's. Often one would ge put
in upside down and blow a bonding wire. I used to take
these and pop the top off and rebond a new wire for the
blown one. They always worked after that. I'd just
epoxy the lid back on. I think I still have a few
of these in my parts box someplace.
