PTFE Coated Fiberglass Solar Stringer Conveyor Belt
1. Product Overview
PTFE coated fiberglass solar stringer conveyor belts are precision-fabricated conveying components engineered specifically for automated photovoltaic (PV) solar cell stringer and soldering machines. Constructed from a high-density woven E-glass substrate impregnated with PTFE and integrated with an anti-static carbon-loaded zone, these belts feature precisely arrayed CNC-punched perforations. The perforation pattern enables reliable vacuum suction to hold fragile silicon wafers securely in place during high-speed indexing, while the non-stick fluoropolymer surface prevents flux and solder residues from adhering during thermal soldering cycles.
