I was wondering if those of with experience running ENIG line could help me with some issues we are encountering. What is the reasons for discoloration of gold? We have tried rinsing in hot DI, drying immediately after coming out of the gold solution as to not allow water to dry on the surface, but we still encounter small amounts of tarnish or discoloration. This is new for us and your help would be appreciated.
