What is Heavy copper PCB?

Heavy copper PCB products are widely used in power electronic equipment and power supply system.The additional copper PCB thickness enables the board to conduct a higher current, achieve good thermal distribution and implement complex switches in a limited space.

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.
