Hello,

We have a problem with one of our circuit board vendors who applied solder
mask to the gold fingers on a lot of 100 boards. Naturally, the 100 boards
were built up and the problem wasn't discovered until test. Does anyone
know of a way to remove it without losing the gold on the fingers?
Solvent or ??

Thanks.

If you mean that green varnish type solder resist, you could try Nitromors
paint stripper otherwise a possibly more difficult to track down solution is
Oxley Developments Resin Dissolver. A company I worked for years ago used
this stuff to dissolve thermosetting bonding mats used to stick ultrasonic
transducers to the bottom of cleaning tanks - you don't want to soak PCBs in
it though, it'll dissolve them as well!

Hold on though - cant the PCB firm tell you what'll shift it?!
