And thanks for the tip about getting silver to drop by diluting with HCL Dave!
My apologies, when I said silver pins I meant silvery wires from chips. Also possibly coated with PGM if I'm not mistaken.
 
I wouldn’t get to excited about finding PGMs in e scrap they are not that common, Soviet manufactured material used them extensively but much rarer in the west except in old telephone exchanges newer telecom boards that look rubbish and some military applications. There may be others but as I said not commonly found.
 
Thanks for the reply nickvc, I think you are right. But I have read on here repeatedly though that there may be some on the braze of the silicone wafers and also some on the wires from the chips. Maybe it's best to address that in detail for the members hehe.
