Connect-Inter Ribbon-Machine welding

1) welding ribbon for big power solar panel:

   Copper base: electrician Park copper (TR line) rolling or T2 copper tape slitting
   Copper substrate resistivity: ρ ≤ 0.0172Ωmm2 / m

   Solder Composition: 62% Sn36% Pb2% Ag; 60% Sn40% Pb; 96.5% Sn3.5% Ag (Bi optional).
   The thickness of the tin layer: 10μm-40μm, sided uniform
   Thickness deviation: ≤ 0.008
   Width deviation: the rolled products ≤ 0.1mm; slitting Commodities ≤ 0.005mm.
   Elongation: the soft state ≥ 20%; semi-soft state ≥ 15%.
   Specifications: width 1.5mm-2.5mm; thickness 0.08mm-0.25mm. (here is 1.5*0.2 mm)

   Packaging: cardboard, " I shape" wheel, box.

   Suitable for DIY solar cell and solar panel, also suitable for machine automatic welding middle without decapitation; crop for customers Length carton packaging.
