Copper Foil description

Copper foil has low surface oxygen characteristics and can be attached to various substrates, such as metals, insulating materials, etc., and has a wide temperature range. Mainly used in electromagnetic shielding and anti-static, the conductive copper foil is placed on the substrate surface, combined with the metal substrate, has excellent conductivity, and provides electromagnetic shielding effect.

Copper Foil Application

•   Copper clad laminate (CCL) and copper foil for printed circuit boards (PCB): CCL and PCB are the most widely used areas of copper foil. PCB has now become an indispensable main component for most electronic products to achieve circuit interconnection. Copper foil has now become a key material for PCBs that play a role in supporting and interconnecting components in electronic products. At present, most of the applications in CCL and PCB industries are electrolytic copper foil.

•   Copper foil for lithium-ion secondary batteries: According to the working principle and structural design of lithium-ion batteries, anode materials such as graphite and petroleum coke need to be coated on the conductive current collector. Because of its good electrical conductivity, soft texture, mature manufacturing technology, and relatively low price, copper foil has become the first choice for the negative electrode current collector of lithium-ion batteries.

•   Copper foil for electromagnetic shielding: Mainly used in hospitals, communications, military and other areas that require electromagnetic shielding. Due to the limitation of the width of rolled copper foil, the electromagnetic shielding copper foil is mostly electrolytic copper foil.
