Heavy Copper PCB
Heavy Copper PCB or calls Power Supply PCB is manufactured with copper weights anywhere between 3-20oz/ft2, Copper weights above 20oz/ft2 are also possible and are referred to as extreme copper. the increased copper weight combined with a suitable substrate and thicker plating for the through holes transforms the once unreliable,weak PCB (Quick turn around PCB) into a durable and reliable wiring platform. Now various power electronics products are being designed every days for a range of applications: such as Power line monitors, High power rectifiers, planar transformers, and power convertors,etc.
