3 oz solder mask plugging ENEPIG heavy copper board
Heavy Copper PCBs are extensively used in the Power Electronics and Power Supply systems where there is a high current requirement or a possibility of quick shooting up of fault current. The increased copper weight can turn a weak PCB board into a solid, reliable, and long-lasting wiring platform and negates the need for an added costlier and bulkier components like Heat sinks, fans, etc.
