Anyone knows if there are some issues when you solder Silver finish components on Ni-Au finish pads with Sn/Pb/Ag solder paste (Indium)? (I must use components with silver finish)

Thanks

If you let the silver content of your solder connections get much above 3 percent, it could cause reliabilitility problems, similar to the problems caused when the gold content gets too high.

It will be hard to solder metal that finish by any coating. So you should remove the coating first. You need strong acid to remove coating. After you solder both then you can silder finish esay.
