So if Au isn't the thing, what's the better answer? HASL Sn is the other common option and I can smell tin whiskers as the counter argument to that. Electroless Ag?
Don't even think of suggesting regular HASL Sn/Pb - none of the PCB shops will do that here (RoHS).

You may need to remove the Au before soldering. _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
