Ring PCB, your PCB & PCBA Turnkey Solutions | Professional Circuit Manufacturing Expert 1.What Are Heavy Copper PCBs? Heavy copper PCBs are also known as thick copper PCBs or power PCBs. They are unique due to their significantly thicker copper layers typically ranging from 3 oz/ft up to 20 oz/ft or more. Standard PCBs typically have copper thicknesses of less than 2 oz/ft , so the enhanced current-carrying capacity of Heavy Copper PCBs makes them suitable for high
