Main materials of the PVC-dipped flexible connector: High-quality copper foil with a thickness of 0.04-0.32mm is used, commonly 0.11mm thick T2 copper foil. The upper and lower surfaces are laminated with 0.11mm thick pure nickel strips or 0.13mm thick nickel-plated copper sheets. The stacked parts are pressed together, and the ends or perforated parts are bonded using polymer diffusion welding, then formed by heating and pressing with high current. A heat shrink tube is used for protection in the middle, and for large-sized special-shaped products, the middle part uses a PVC-dipping process.

Plastic-coated flexible connectors are not recommended for tin plating, nor for overall electroplating. With overall electroplating, during the process, the plating solution can seep into the non-soldered areas of the flexible connector, namely the soft areas in the middle laminated section. This can leave chemical residues, which generate corrosion products from the inside out, reducing conductivity and shortening the product's lifespan. During salt spray testing, the residual substances inside can be observed with the naked eye, showing obvious black corrosion and oxidation.
