Thick Copper PCB Assembly

Thick copper PCB products are used extensively in power electronic devices and power supply systems. A growing trend in the PCB industry, this unique type of heavy copper PCB features a finished copper weight of more than 4oz (140μm), compared to the 1oz (35μm) or 2oz (0μm) copper weight generally found in those with a standard PCB copper thickness.

NOD Electronics is a highly skilled PCB manufacturer that can develop and produce a superior thick copper PCB product of the highest quality. We offer a thick copper PCB manufacturing service that uses copper weights of up to 15oz (525μm).
