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