Hi,
I have a question on Gold surfaces. It seems that one of my assemblies has a
weird film or contaminates on the pads.  The board is double sided, we ran one
side and then it sat (shortages) for a week. It almost looks like copper! We
did check incoming boards before placing parts and it seems they have the same
problem but not as bad. I guess after wash this problem got worse. Has anyone
had this problem before and if so, what was the cause?

Thanks in advance
Angie
