Welding flux again oxidized surface, an outer solder reduce tension, improve welding performance. Flux performance will directly affect the quality of electronic products. Flux component, lead-free flux in recent decades, electronic products soldering process in flux rates, and more generally the use of rosin resin system mainly consists of rosin resin, halide-containing agents, additives and organic solvent composition flux. Such flux although good weldability, low interest rates, but high after welding residue. Wherein no active agent, a non-activated rosin (R) of pure rosin dissolved in a suitable solvent (e.g. isopropanol, ethanol, etc.) in the composition. Limited ability to eliminate oxide film flux brand, it requires weldment has a very good weldability. Typically used in some absolutely not allowed to use the presence of corrosive hazardous circuits, such as cardiac pacemakers and other implanted. Be able to promote wetting, weakly activated rosin (RMA) flux in such active agents are added lactic acid, citric acid, stearic acid and other organic acids and salt-forming organic compounds.
