There are some XRF units that can measure the different thickness of metal platting. I have not used one to verify platting thickness of a questionable PCB, but watched the feature demoed during a sales pitch. It was pretty accurate in determining the plating thickness of the gold but became less accurate as you penetrated the different platting layers. I don't think a solder test will do you any good, the pad may wet just fine but cause reliability issues in the field. What class assembly is this? Is it a high runner that may require a large recall if something were to go south? I would have so sort of testing done just to make sure everything is as it should be.
