Gold Flash Mating — When It Works, When It Doesn't
Gold flash handles a few dozen to a few hundred mating cycles before the underlying nickel or copper starts to show. For a production harness that mates once and stays mated, that is fine. For a field-service connector that gets disconnected quarterly, spec the thicker gold option in the Minitek range. Tin wets well with standard SAC305 solder profiles and gives a reliable fillet on the SMD pad.
