Analysis for soft gold plating process, removing

2013-3-14  We used to do a lot of lead frame plating with pure gold during the 1970's. The gold bath was a so called neutral bath that operated at pH 6-7 and 160 deg F. No free cyanide but the gold was added as PGC. When the sum of the concentrations of nickel, iron and copper totaled 50 ppm we would treat the bath with a stoichiometric amount of sulfide.
