A long time ago - like about 1980, I used a copper tape with conductive
adhesive to create plating thieves in vast expanses of photoresist that had
been sparsely populated with isolated holes and pads.  If well applied, the
tape adhesive would stand up to the plating chemistry and preplate
solutions.  I do not remember the product name but it came from 3M.  We ( I
was with Sperry Univac Defense Systems back then) used a hand cranked
clothes ringer to squeeze the tape but  Western Magnum has more advanced
ways to apply mechanical pressure to the tape. I have found a couple of
rolls of similar tape here (at GE Fanuc) but I'm not sure if it has a
conductive adhesive.  It is 3M Electrical tape and the bag says Tape No.
1181.  Good luck!

        Does anyone have a list of manufacturer's of adhesive copper tape
capable of withstanding  plating conditions?
