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.   
Heavy Copper PCB makes it possible to integrate high current circuits and control circuits to realize a highly dense, in a simple board structure,also the advantages include reduced layer count,low impedance power distribution,smaller footprints and potential cost savings.
