steve, are you doing any gold finger adhesion test? I know many of vendor do not like the test and consider it is not accurate. But it helps a lot when you check for consistancy. http://www.intertronics.co.uk/products/cint871.htm my 1.7 cents... jk -----Original Message----- From: TechNet [mailto:[log in to unmask]]On Behalf Of R Sedlak Sent: Friday, October 28, 2005 3:56 PM To: [log in to unmask] Subject: Re: [TN] Gold Plating Peeling... Steve: The usual cause of peeling plating is plating on to a dirty/oxized surface. Can it be reworked.... possibly, making sure that you get rid of the original problem which caused the problem initially. Can it be reworked in a way which is essentially guaranteed to work 99+% of the cases? Probably not. Perhaps some sort of incoming inspection/test might be worth considering?

I really wasn't that wicked, but I was confronted with a new problem this morning. We just built some assemblies and conformal coated them, but when they were being de-masked, the gold plating on the fingers started peeling up! Check out: http://www.stevezeva.homestead.com/files/Peeling_Plating.jpg http://www.stevezeva.homestead.com/files/Peeling_Plating_2.jpg I have a couple of questions: Can I repair this? If I repair this, should all fingers be stripped and repaired?
