Hi Mike! I have had very good success with the application of SERA on characterizing the solderability of both tin and tin/lead surface finishes. However, just because you have a "quick" test it doesn't mean you have an understanding of the solderability of a surface. The ANSIJ-STD-003 has several test methods that may be useful in addition to SERA testing. What are your expectations of the solderability test results and how do you want to use that data?

As a fabricator of QTA product, we have little time for verification, but like most of you, the end product liability is tremendous. Tests that verify first time solderability are not relevant. Thru-hole coupons are likewise not preferred as extremely little product is of that technology. The issues are multiple thermal cycles using various methods of heating. I've heard SERA tossed around, but would that be practical for testing other than virgin product?
