Interesting reference - does gold poison solder joints?

Thanks for the link - very interesting.

The photos show the intermetallic layer clearly - the question is, is it audible and how much effect?

Also, if the gold layer must be wicked away by molten tin prior to soldering, is it something a DIYer can do successfully? By just applying solder to the gold-plated part and wicking it away before completing the joint?

I believe John Broskie recommends using a fine sand paper to physically remove the gold, but that seems hard to know when you are done.
