About PV 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:
The Core Technology
1,Forming of round wires to flat wires through drawing and rolling
2,Heat tretment
3,Hot-dip tinning
4,Precise spooling
Quality Assurance
1, Technology and Equipment
1) Advanced technology and equipment from German
2) Advanced measuring technology
3) Stability and reliability of products
2, Management: ISO9001:2000
3, Certificate: SGS, TUV
Specifications
Storage Conditions and Shelf Life
Tinned copper ribbon should be stored in diry and ventilated room, where sholud be no acid,
alkali, or harmful gas and the indoor relative humidity should not exceed 60%. Place it horizotally while stacking and avoid the carton extrusion, meanwhile, the stacking quality of same product should not exceed five layers or 1 ton. The shelf life can be up to six mounths since the production date.
