Difficult to clean because of a halogen ion, the residue of high ion, a halogen element (mainly chloride) strong corrosive flux, no-clean flux and therefore not suitable for use as a raw material, the outer halogen-free surfactant, little activity A weak, but a small residual ion. The appearance of the active agent is mainly fatty acids and aromatic nonionic surfactant look flux manufacturers, wholesale, its main function is to reduce the appearance of tension between the solder and lead metal produced when the foot contacts, and enhance the appearance of wetting. Cosolvent: prevent activation agent off the solid component from the solution dissolved the trend and prevent adverse non-uniform distribution of the activator, film formers: leadfingers solder flux during Which is good, flux coated precipitate, crystallization , form a uniform film, its pyrolysis residue after successful due to the presence of quick curing agent, curing, reducing the viscosity. Common action flux flux how to use, destroy a metal oxide film of the solder surface cleaning, facilitate the creation of solder wetting and solder alloy. Solder outer cover to prevent solder or metal to oxidation. The role of flux | Shangqiu Flux | FUJIE solder provided by Zhengzhou City Fujie solder materials Limited.
