Take a look at J-STD-003, Solderability Tests for Printed Boards. This may help you create a procedure.

the pin manufacturer usually recommends the proper hole size. the hole diameter should be from .001" to .003" undersize depending on the design of the contact area on the pin.

Chris As you imply, testing board and component solderability prior to assembly is preferred. * ANSI/J-STD-002 - Solderability Tests for Component Leads, Terminations, Lugs, Terminals, and Wires * ANSI/J-STD-003 - Solderability Tests for Printed Boa

I just wonder anyone had the idea of solderability test for through hole by using a wetting balance equipment? I read the jstd002/003 however my feel is now our machine (metronelec st60) is not capable of this test?

We just measure the coupon before and after. We are always btw .002" - .003" acrylic. No auditor will say a word if you are doing this much control. Unless its NASA I suppose..... we've never had a problem with any of the avionics guys doing this tho

Re: item 3 - there are ultrasonic thickness machines (Panametrics makes one) that can measure coating dry with a small transducer head. A little pricey for ones that measure reliably in the .003" +/- .002" range.
