I am not sure that this is a worthwhile exercise. Even if they pass your tests, (I admit that if they fail then problem solved) our experience would say that ENIG is a difficult finish to get consistently supplied. Therefore the integrity of the supplier is vital and their approach to problems is also of concern. Best of luck.

I have been examining their sample boards, and while one oif them shows a normal ENiG grain under 800x magnification, the other is flat and dull. I believe it might be just gold plating. It's hard to tell from the cross sectons they sent (those display their own set of concerns). I'm trying to find some images to compare these, but I'm having no luck. Does anyone know of a good site where I might find some ENiG and Gold images?
