Welding methods:
Pressure welding soft connector
■ The pressure welding is to press the copper foil laminations together, using molecular diffusion welding, and forming by high-current heating and pressure welding.
■ Copper foil: 0.03mm to 0. 3mm thick.
■ The contact surface can be tinned or silver plated according to users’ requirements.
Brazed soft connector
■ Brazing is to press the copper foil laminate together, using silver-based brazing solder, and butt welding with the flat copper block.
■ Copper foil: 0.03mm to 0.3mm thick.
■ The contact surface can be tinned or silver plated according to user requirements.
