Halogen free no-clean flux 663A Introduction

Flux is an important material for SMT electronic welding, which is a mixture of chemical and physical activity. When heated, it can remove metal oxides from the solder and solderable surface, promoting the wetting of the metal substrate by the molten solder. Flux can prevent surface oxidation during welding, reduce surface tension of the solder, improve welding performance, and directly affect the quality of electronic products. Unibright's fluxes include water-based fluxes, halogen-free fluxes, lead-free fluxes, water-soluble fluxes, and are widely used in wave soldering fluxes, electrical component fluxes, photovoltaic fluxes, and more.
