Process Technology:
The manufacturing process of copper foil soft joint is usually taken pressure welding or brazing welding.
Pressure welding :that is to press the copper strips or aluminum strips together firstly then use the molecular diffusion
technology to weld such strips to be an integrity by high current heating. 
Thickness of copper strip and aluminum strip: 0.05mm to 0.3mm.
Remarks: the contact surface can be tinned, nickel plated or silver plated according to the user's requirements (except for aluminum strip).
Brazing welding :that is to press the copper strips or aluminum strips together firstly, then use the silver-based solder to butt weld these strips to flat copper block.
Thickness of copper strip and aluminum strip: 0.05mm to 0.3mm.
Remarks: the contact surface can be tinned, nickel plated or silver plated according to the user's requirements (except for aluminum strip).
 
Main applications:
1) Mainly used in electrolytic aluminum plants, non-ferrous metals, graphite carbon, chemical metallurgy and other industries.
2) Suitable for all kinds of high and low voltage electrical appliances, vacuum electrical appliances, mining explosion-proof switches, automobiles, locomotives and other related products.
3) Used for connection between large transformer and rectifier cabinet, rectifier cabinet and isolating knife switch and connection between busbars.
