No-Clean Solar Photovoltaic Soldering Flux WTO-518G

Description

WTO-518G is a no-clean soldering flux specifically developed for solar photovoltaic applications. Formulated with modified resin, organic activators, selected additives, and solvents, it provides moderate activity with excellent wettability and strong penetration. The formulation ensures stable processing, fast action, and reliable soldering performance for PV module manufacturing. Its no-clean design keeps surfaces clean while maintaining high electrical reliability. The flux is halogen-free, environmentally compliant, and produces minimal odor during operation.

Applications

• Solar photovoltaic manufacturing processes
• Welding of photovoltaic components
• Soldering of ribbon tapes in solar PV modules
• Dip and spray fluxing processes
• Applications requiring clean surfaces and high electrical reliability in PV assembly
