KNOWLEDGE

Bond wire is the main material used in semiconductor packaging, which is the part connecting pins and silicon wafers and conveying electrical signals. It is an indispensable core material in semiconductor production. With only a quarter of a meter in diameter, the production of bonding wire requires high strength, ultra-precision and high temperature resistance.

As we all know, Copper braided wires, copper stranded wires, copper flexible connectors, bare copper wires can be widely used for transformer installation, high and low voltage switch cabinets, vacuum appliances, closed bus ducts, generators and buses, rectifier equipment, rectifier cabinets and isolating switches, automobiles, electric locomotives, industrial furnaces, mining explosion-proof appliances, generator sets, carbon brush wires and the connection between buses.

Generally, bare copper wire is made of pure copper, and tinned copper wire is coated with tin by hot tinning process on the basis of bare copper wire. The difference between the two can be clearly judged from the color.

Equipotential bonding wire of new energy vehicles is also called Copper Braided Connection Wire / Copper Braided Connector. In electrical terminology, equipotential bonding is also called protective grounding. The definition of equipotential in Lightning and Lightning Protection Engineering "equipotential connection is to connect all metal objects in and near the building, such as steel bars, water pipes, gas pipes and other metal pipes in concrete, machine foundation metal objects and other large buried metal objects, cable metal shielding layer, zero line of power system and ground wire of the building with electrical connection method (welding or reliable conductive connection) Make the whole building a good equipotential body.
