Thanks Steve,

I usually keep some good sections and other images too. Don't have anything
showing them with me on this computer. I'll find some and a surface shot of
the type of surface being discussed, another time.

I just can't get over what a really bad hole is shown but how really good
the surface plating is. Luck and no skill at work here. Funny thing is, I
didn't even know this board had been produced this way. Had an open
somewhere and buzzed it out and found a suspect are and sectioned it. Wala,
a blind, plated over via with no plating in the hole. I can't believe the
shop, who did very little in terms of sophistication, actually did the
sequential lamination and plated over the resin so well.

Earl
