Electronically calendered copper foil is a product made by repeatedly rolling and annealing high-precision copper strips (usually less than 150 microns in thickness) based on the principle of plastic processing (usually 4-100 microns in thickness and<800 mm in width). Its ductility, bending resistance and conductivity are better than electrolytic copper foil, and its copper purity is also higher than electrolytic copper foil. Copper foil is used to make printed circuit board (P
