Thick Copper PCB

Most PCBs are constructed with a 1 oz (35 um) or 2 oz (0 um) copper weight. Thick copper PCBs have a finished copper weight of more than 4 oz (140 um). The thickness of the copper allows thick copper printing circuit boards to conduct a higher current, achieve good thermal distribution and implement complex switches in a limited space. Heavy copper printed circuit boards are generally employed in a wide range of power electronic products and power supply systems.

JingHon offers a thick copper PCB manufacturing service that uses copper weights of up to 15 oz (525 um).

To ensure the PCB is fabricated correctly, it is important that customers take the increased width of traces and spacing between the traces due to the increasing copper weight into consideration.
