Copper Foil

Shanghai Nosinda Metal Co,Ltd is a leading Copper Foil manufacturer and supplier.

Copper foil is an extremely thin foil with thickness below than 150μm processed by electrolysis, rolling or sputtering. It is widely used in electronic circuits, lithium-ion batteries and other related fields. According to processing methods, copper foil can be divided into electrolytic copper foil(ED copper foil) and rolled copper foil(RA copper foil). Electrolytic copper foil is formed by making copper sulfate solution from copper raw materials, and then using electrolytic equipment to electrodeposit the solution under the action of direct current. Rolled copper foil is made by repeatedly rolling copper raw materials by physical means. The production cost and technical threshold of electrolytic copper foil are low, and the application scale is huge. It is mostly used in the fields of rigid copper clad laminate and lithium battery. The production cost of rolled copper foil is high, the technical threshold is high, and the application scale is small. It is mainly used for flexible copper clad laminates(FCCL).

Due to its good electrical conductivity, reliable corrosion resistance and plasticity, copper foil is often used as the conductive layer of printed circuit board (PCB). In addition, copper foil also plays an important role in the semiconductor industry. Copper foil can not only be used as a microscopic connection of semiconductor devices, but also as a conductive shielding material for various equipment in the semiconductor manufacturing process. Copper foil also plays the role of signal transmission in the field of communication. Copper foil can act as connectors, reflectors, etc. in cables, antennas, and communication equipment to facilitate equipment communication and signal transmission.
