T2 calendered copper foil 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 between 4-100 microns in thickness and less than 800 mm in width). Its ductility, bending resistance and conductivity are better than those of electrolytic copper foil, and its copper purity is also higher than that of electrolytic copper foil. Copper foil is used to make printed circuit board (P
