TechNetters,
I have checked the archives and have not been successful in finding
sufficient info on the titled subject.  Either I have not done a diligent
enough search or the info is not there.  So, here are my questions.
1) If you were presented with varying amounts of what looks like water
stains on immersion gold pads how would you determine its composition?  No
guesses now, I can do that.  I want to know how people have actually done
it!  Also, I am not referring to "purple plague" but just slightly off color
gold.
2) Has anyone ever been able to correlate amount of staining to
solderability issues?  Or is it a non-issue?
3) Has anyone seen staining cause problems with respect to keypad electrical
continuity?

regards,
Bev Christian
