Hi, I have a general question about PCB manufacturer.
The fab house told me that when I use 1/2OZ copper foil (.7mil) on external layer, after plating additional copper for PTH, it goes to about 2.2mil. Is that true?
What are the minimum copper plating thickness? Does it depends on the PTH copper thickness? Thanks.
