We are designing a small board that requires some very small gold contacts
for wire bonding one part (bare-die). The "pads" or contacts are 10 x 15
mils. The rest of the pads and traces on the board don't need any gold, so
we would prefer not to plate the whole board, for obvious reasons.
Is it possible to gold plate just certain pads, and not others?
These pads are not near the board edge, but could be re-designed to be close
enough to run traces to the edge to hook-up current, if that would work.
Any suggestions or war stories on this situation would be helpful.
Thanks - TC
