Copper Flexible Connector
The 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 hotpots under load.
