Tabber and stringer connect crystalline cells and make them a line. Later these lines are further connected and a module is formed.
Crystalline cells and electrically conductive lead are set and soldered in tabber and stringer, where steel belts are perforated for aligning cells by suction and also fluoroplastic-coated to get a line of cells removed smoothly after soldering. Steel belts withstand more than 200 degrees of Pb-free soldering.
