TechNetters,  surface solderability of a batch of boards has been questioned by a customer. J-STD-003 solderability testing before the boards were shipped, and again, on spare coupons, after receipt by the customer was unremarkable, i.e., everything passed.

In that context, I am wondering what analytical tools are suitable for analyzing a surface for possible contaminants or residue, in particular those which might inhibit soldering. Some searches of the archives since 28 Feb 2012 turned up no postings relating solderability and surface analysis.

Thanks for any information or comments.
