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?
