Thick Copper PCB
Power electronic devices and power supply system use thick copper PCBs extensively. This unique heavy copper PCB is a growing trend in PCB manufacturing. It has a copper weight that exceeds 4oz. (140mm), as opposed to the usual 1oz. (35mm) and 2oz. (70mm).
The extra copper thickness on the PCB allows for a board that can conduct a greater current, have a good thermal distribution, and incorporate complex switches within a small space. The board can also be made smaller by using multiple weights in the same layer of circuitry. It is also possible to increase the mechanical strength of connectors.
