Hello all, I have a question concerning the stack-up for a 2 layer board in which I need 3 oz. copper plating in the barrels. What copper foil thickness should I specify? I want to insure that I get 3 oz. copper for all lands/traces and in the barrels of all holes. I have never specified 3 oz. copper and didn't really know what is typically done for 3 oz. copper.
