About Tabbing Ribbon & Bus bar Ribbon

PV ribbon is composed of Copper and coating alloys, and divided into Tabbing Ribbon and Bus bar ribbon.

1. Tabbing Ribbon

Tabbing Ribbon commonly connects the positive and negative sides of the cells in series.

2. Bus bar Ribbon

Bus bar Ribbon concentrates the cell stringing into junction box and channels electrical current.

About Coating Alloy:

The coating type is determined by the customer’s design and demand. It is divided into leaded and dead-free coating. At moment the leaded coating type is widely used, but in the future it will be developed to lead-free coating type.

Main coating alloy types and melting temperatures as follows:

Specification of Busbar Ribbon

Technology Process

1,Forming of round wires to flat wires through drawing and rolling

2,Heat tretment

3,Hot-dip tinning

4,Precise spooling

Copper base is the oxygen free copper strips perssed 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 tin alloy coat is produced by professional hot-dipping tinning equipments imported from Japan. Coat suface is bright and even, it has atable performance and strong antioxidant which helps to imporve the welding yield. Its thickness can be adjusted by customer requirement. 

The ribbon can be made to order according to solar module and it's dimension

1,Raw material: we use high-quality materials which ensure the fine conductivity.

2,Molding: We use high precision equipments which ensure the thickness and width of the material.

3,Heat treatment: We use advanced heat treatment equipment with independent innovation to ensure the physical properties of the material.

4,Surface treatment: We use whole sets of the cleaning equipment to ensure the smooth finish of the material surface.

5,Tin-plating: The automatic tin-plating system ensures the stability of the products quality.

6,Packing: our different kinds of packing methods can meet different requirements of customers.
