High Precision Rolled Copper Foil
Inquiry
Product introduction
Lamination metal foil is a high precision, ultra-thin copper product with a thickness typically ranging from 4-100 microns and a width generally less than 800mm. It is made by the principle of plastic deformation processing, repeatedly rolling and annealing high precision copper strip. Lamination copper foil has excellent ductility, bendability, and conductivity, with a copper purity higher than that of electrolytic copper foil.
The product is mainly used for the production of printed circuit boards (PCB), copper clad laminates (CCL), and flexible copper clad laminates (FCCL), flexible printed circuits (FPC), 5G/6G communication, electromagnetic shielding, and heat dissipation substrates.
