Solder Wire 1mm Sn99.3% Cu0.7% 30g Solder Tin Flow Solder Tin Rosin Core Soldering Tin Coil for Electrical Soldering Repair

Solder wire made from alloy composed of 99.3% tin and 0.7% copper contains 2% rosin-based flux. With anti-oxidant properties this pure and safe material will not darken or deteriorate even after prolonged storage. Its welding performance is stable and it is specially designed for high-precision electronic welding. This welding wire features excellent fluidity and excellent wetting power. It heats evenly applies smoothly and adheres perfectly to small pads and pins of components. It helps you eliminate common defects such as faulty welds false welds and peeling. The welds are shiny full strong and durable with increased strength making it perfectly suitable for all kinds of fine welds and precision electronic repairs. This soldering wire has a melting point of approximately 227 °C suitable for a standard working temperature of 380 ± 20 °C. It is less corrosive and therefore safer. Its low melting point fast melting speed and high efficiency effectively reduce the thermal shock caused by high temperature on PCB and precision chips eliminating the risk of component burn and card deformation. It is suitable for both repairs and DIY projects for beginners. The solder wire uses an improved low-residue formula allowing soldering without spattering or pungent odour for clean and worry-free work. Residue after welding is minimal making further cleaning unnecessary and significantly improving work efficiency. Combined with high insulation resistance it provides stable conductivity effectively avoiding the risk of short circuit and electrical leakage and ensuring stable and long-lasting operation of the equipment. This solder wire has a standard diameter of 1.0 mm and can be used for precision micro-soldering repairing home appliances and small industrial soldering. Each spool weighs 20g net for a total weight of 30g. The spool is wound well which prevents knots and breaks. Easy to store and use convenient for daily use.
