Hi Henry, If you have any images you want to share, send them to me and I'll post them. Steve ----- Original Message ----- From: "henry rekers" <[log in to unmask]> To: <[log in to unmask]> Sent: Wednesday, November 26, 2008 6:17 PM Subject: [TN] nickel erosion Any technetters out there experiencing this mysterious nickel erosion process with enig boards on their leadfree waves? Apparently there is a committee set up already. I would like to share experiences if anyone is willing to come forward. Essentially, the defect shows up as a dewet on the annular ring of the TH devices. On cross section, there is large amounts of nickel eroded away and the surface is non-wettable. No corrosion is evident, so it's NOT black pad. Anybody? __________________________________________________________________ Instant Messaging, free SMS, sharing photos and more... Try the new Yahoo!
