50G Solder Wire Rosin Core 0.4mm/0.6mm/0.8mm

RF4 50G Solder Wire Rosin Core For Mobile Phone Repair Soldering 0.4mm/0.6mm/0.8mm Soldering Tin Wire Product features and details: Environmental lead-free Good wettability, electrical conductivity, heat resistance and fatigue The solder joint is smooth and can effectively resist oxidation. The diffusion speed is fast even if the through-hole is small. The solder wire is evenly wound with a drum for easy sorting and preservation.   (1) In the welding process, the solder wire and the soldering iron work together. Based on the quality of the soldering iron can provide a stable continuous temperature, solder wire can be added to the cracks of electronic components as a filler, it is the main unit of solid electronic components, but also an indispensable part of every welding. (2) Environment-friendly, lead-free wettability, conductive property, heat resistance, fatigue resistance, smooth old joints, effective oxidation resistance, fast spreading speed, even if there is a small through
