SpletCopper weights above 20 oz/ft 2 and up to 200 oz/ft 2 are also possible and are referred to as EXTREME Copper. Our discussion will focus primarily on Heavy Copper. The construction of a heavy copper circuit endows a board with benefits such as: Increased endurance to thermal strains. Increased current carrying capacity. SpletGood PCB fabrication practice calls for a minimum plating thickness of 1 mil (25,4 microns) in a plated through-hole or via. One ounce copper is 1,4 mils (36 microns) thick. Half ounce copper is 0,7 mils (18 microns) thick. Therefore, the plating in the hole is roughly 0,75 ounce copper or midway between one ounce and one half ounce.
