Super Flux Korean Solder Wire 1KG 1.0mm 2% Flux 63/37 قصدير كوري 1 كيلو أصلي

Super Flux Korean Solder Wire is a 1 kilogram spool of 63/37 tin-lead solder with 2% flux and a 1.0 mm diameter. Manufactured to provide consistent melting behavior, the eutectic 63/37 alloy transitions directly from solid to liquid at a single temperature, helping to reduce cold joints and improve wetting on copper, component leads, and PCB pads. The 2% flux core aids solder flow, removes light oxides, and promotes strong, reliable joints during through-hole and general-purpose electronics assembly. This solder wire is suitable for hobbyists, technicians, repair shops, and production environments where a conventional tin-lead alloy is specified. The 1.0 mm diameter provides a balance between control and flow, making it convenient for hand-soldering of connectors, wires, components, and small mechanical parts. The 1 KG spool offers extended usage for repeated repairs and assembly tasks without frequent spool changes. For best results, use a temperature-controlled soldering iron set to the recommended range for 63/37 solder, keep iron tips clean and well-tinned, and apply heat efficiently to the joint rather than the solder itself. After soldering, remove flux residues where necessary according to the flux type and application requirements. Store the spool in a dry environment away from corrosive vapors and extreme temperatures to preserve solder quality and flux activity.
