SMART FILM BUSBAR TOOL COPPERFOIL

smartfilm 

 custom cut sheet ,our busbar is different with other supplier , we use copper mesh , the film installed used regular red and black wire after some years didn't work any more, the reason is that 

copper wire will be oxidized and no electricity pass through. So we use copper mesh. The black/red wires are welded on copper wire doesn’t connect with ITO(electric conductive layer) directly in normal busbar, our copper mesh busbar put the black/red wires on copper mesh and copper mesh directly pasted in ITO layer, so the conductivity is better, and electricity will be nomarl although  the copper wire is oxidized  after a period of time（And our copper wire is silver-plated to prevent oxidation)

We use silver color copper foil ,Will not oxidize along with time , this silver color copper foil more than 3times price than copper foil

We used imported silver paste , The conductivity is 3 times higher than that of domestic silver paste 

below is some pictures for our copper foil (silver color ), we have two options to choose 

one width is 5mm, for those client use reguler busbar , black and red wired in different side , one options is 10 mm , for those clients that want black

and red wire welded in same side so , fold one side busbar into anothe side from top or from side 

less trouble during installation ( we don't suggest)
