Here is a thought, this is from the mechanical side.    What diameter is 
bored in the board?    Fashion a go-no go gauge that is the bore of the 
hole minus the minimum thickness plating allowed.   If it fits it is a 
no go, you can also make one with the bore minus the maximum thickness 
allowed.
Also known as a pin-gauge, we used these all the time to verify 
calibration of crimping tools that require a minimum crush factor.
