[QUOTE="Shonver, post: 96202, member: 34"] In assemblies required to deliver high levels of reliability, it is common practise to de-gold the joint when soldering onto gold-plated parts. The de-golding is effected by applying solder, then removing it (the gold dissolves). I remember well, before I got to know about this, how that I was puzzled by one wire that just fell off a joint after a few months; I had carefully soldered my first gold connector, but the joint had failed prematurely. I believe the effect is known as intermetallic (reaction). A consultant from the CSIR, advising us on the requirements for the design of a highly rugged product, recently warned us to keep away from gold-plated PCBs. [/QUOTE]
