I have had some parts returned for a contamination/tarnishing on parts with gold plating. These parts are sent out for plating and we are having a difficult time identifying a root cause. The problem seems to be different from a "black pad" problem. The parts were plated approximately three months ago, and the tarnish is very evident. I would appreciate some feedback.
Thank you,
