In my opinion, there probably is not a perfect test for PCBs, but there are
several that can be used to determine solderability. My preference is a
float test that uses a coupon that has PTHs reflective of the board of
concern. In most cases, I expect the solder to fill the barrel in an
expectable hole.

Lee,
Just follow up on your comment below, is there a perfect test for
solderability?
