Re: Acetone, I guess it was used for the 'soft' plastic of
the smartcards and my feeling is that it would have little
effect on the 'hard' case used on a typical DIP.

Re: Rosin, not tried this but to get Epoxy 'potting
compound' off you can also use the debonding agent used
for releasing glass-fibre items from their production
moulds. Boat repairers would use this so you may be able
to obtain from a yacht chandlery. I believe the active
compound is methelene chloride and it's insanely volatile
so you need a well ventalated area.

It seems most PDIP mould compound materials are filled
Epoxy, with the filler being a mineral or glass,
therefore I think that one should go straight for the
Rosin or debonder and skip the Acetone.
