Annealed copper foil manufacturing process

Apr 29, 2020

Oct 26, 2021 2, rolled annealed copper foil. The manufacture of rolled annealed copper foil requires first heating the copper chains, and then sending them into a series of rollers to reduce them to a specified thickness of copper foil. The rotation creates grain structures in the copper foil, which look like overlapping horizontal planes
