Product Details

Production Processing for Copper Flexible Connector

1

Material Selection

Copper Type: High-purity electrolytic copper (≥99.9% Cu) for optimal conductivity. Form: Typically tinned or bare copper foil for flexibility.
2

Cutting & Shearing

Copper foils are cut to required lengths using precision shearing machines. Laser/CNC cutting ensures dimensional accuracy.
3

Surface Treatment (Optional)

Tinning: Electroplating with tin (Sn) to prevent oxidation. Electro-polishing: For improved surface smoothness. Cleaning: Degreasing to remove contaminants.
4

Welding

Molecular diffusion welding process is adopted. The copper foil lamination parts are pressed together and formed by high current heating and pressure welding.
5

Quality Testing

Conductivity Test: Measures resistance (Ohm's law). Flex Test: Repeated bending to check durability. Pull Test: Ensures terminal strength. Thermal Imaging: Detects hotspots under load.
