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.

Subject: [TN] looking for ENiG photos

Our purchasing group is trying to qualify a new low cost PCB vendor, and
I have some reservations.  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?

Thanks,

Pete
