I seriously doubt it. It is extremely thin and the gold's only real purpose in life is protect the nickel underneath from oxidizing. Once you wear that very thin gold off you will have exposed, oxidized, nickel and loss of conductivity.

Hi, i'm david, new to this forum. Came across your posting about using a delvotec bonder to TS bond to a ENIG pad. Given that the immersion gold layer is thin, does the capillary scrub through the gold layer to expose the underlying nickel? Does your

If the problem as you described as the gold plating contaminated, and the Nickel layer exposed to the solder pot. However, the purpose of the gold layer is to protect the nickel and copper layer not turn into corrosion and resist to other issue (humi

I don't know. We never had craziness like this before lead-free. You should have the yellowish-metal analyzed to be sure. Guessing: You're seeing this color on the terminations of components, not on the bulk of the SnX solder connection. If that's
