Stadem, Sorry, that was a lame attempt at humor. For information, I work for a PWB company. We produce flexible and rigid-flex PWB's. We only use IAg here, but that's the only capability we have. We send our parts out for ENIG. I don't know the history of our success with IAg, but my recent experiences leave a lot to be desired. We have problems with exposed solder, and gold run under. (Under the cover coat of a double sided flex circuit.) As well as gold flaking. It's probably good that we only have limited dealings with SMT, and no dealings with BGA's. Since I'm writing, I have to say thanks to all on TechNet. I've learned so much here that I wouldn't have known about otherwise.
