Stripping silver and nickel from PCBs
+++
We need to remove the nickel plate (immersion nickel) the finish
down to the copper; what is the best chemistry to strip off the
nickel from the copper leaving the copper body and key of the copper
surface smooth and clean? We need to remove the silver plate
(immersion silver) from copper also what is the best chemistry to
strip off the silver and keep copper surface clean?
Thank you very much.
