Introduction of heavy copper pcbs
Heavy copper pcbs are printed circuit boards with 3 or more ounces of finished copper in the inner and/or outer layers.Thick copper/customized heavy copper pcb also known as Power Supply PCB is manufactured with its copper weight between 3-20oz/ft2. Copper with weight above 20oz/ft2 are also possible and are referred to as extreme copper. The increased copper weight combined with a suitable substrate with thicker plating for the through holes transforms the once unreliable and weak PCB into a durable and reliable wiring platform.
