<< Steve,
You know I love you but, how did you get into this in the first place?
Surface copper gets plated "up" to a specified thickness based on hole
plating thickness requirements. If the hole is specified at 1 mil minimum,
usually the surface thickness plating is about 1.2 mils or so thick. The
inners are as specified except for thickness degradation from
cleaning/etching, etc.

Aww crap Earl, who knows? Now I gotta backtrack and try to find out what
happened.
Get a microsection done, prove there's a problem, and then re-build
everything we've built already, in the mean time we're gonna take it in the
shorts money-wise because are finding out after the fact that there's a
problem with this fab...and of course the fab vendor will probably say; "Hey,
we'll give you new boards..." but what about all our material and labor costs
we've already put into this assembly.
Only way to prevent this I guess is to not trust anybody, and do our own
microsections before we accept the fabs in the first place. It'll keep people
honest...
