Technetters, I am currently having problems soldering a switch to A PCB. I have asked the manufacturer what the switch terminals are made of and he has come back with the following: One lead is CuZn37 (Brass) plated with 12 microns of electrolytic gold. Whilst the other lead is the same base with 2 microns of hard bright silver argilion passivation and 2 microns gold. Can anyone tell me the implications of wave soldering this to a PCB? Neil Atkinson
