Product Features:

●  Copper base is the oxygen free copper strips pressed by ultra-precision rolling equipments imported from Germany. It is sleek and no bur edge. The soft hardness can be adjusted by customer requirement.

●  With the particular formula technology, the alloy coat is produced by professional hot-dipping tinning equipments imported from Japan. Coat surface is bright and even, it has stable performance and strong antioxidant which helps to improve the welding yield. Its thickness can be adjusted by customer requirement.

●  The ribbon can be made according to solar module and its dimension.
