Hi
I've always removed glued things from chips by heating it
first with a hot plate. We used to remove the epoxied covers
Ok, anyone know of a safe way of removing a glued
on heatsink? I have a
few of these 486 CPUs where the heatsink is glued down. I could just jam
a screwdriver in and snap it off, but that just doesn't seem very good
for the chip.
Better a single edge razor blade or a putty knife than a screwdriver!
Too much local load with the screwdriver blade - probably crack the
chip.

It was handy to have a wire bonder around ( Ah, the good old days ).
