Heavy copper PCB products are widely used in power electronic equipment and power supply system.
This unique type of thick copper PCB has a finished copper weight of more than 4 ounces (140 microns), compared to the standard PCB copper thickness of 1ozor 2oz.
The thicknees of Copper range: outer ≤ 15OZ, inner ≤ 12OZ.
1、How to achieve the copper thickness of the heavy copper PCB
