SOLDERING FLUX COMPOSITION

摘要

The present invention relates to a flux composition, especially a soldering flux composition comprising 20-60% by weight of phosphate compound containing 50-60% by concentration of phosphoric acid, 10-30% by weight of organic acid, 1-20% by weight of VIII transition element and 5-30% by weight of viscosity modifier. The composition according to the present invention can be broadly applied in our daily lives and industrial fields where welding flames can not be employed, including electricity and electronics, thin tube processing and foil welding fields.
