Features: The lead-free soldering wire has high-purity, long antioxidation time and easy soldering of small parts. Light solder joints, less welding spatter, full solder joints, bright and beautiful. After soldering, a protective film is formed on the surfaces of the solder joints to slows down the oxidation of the solder joints. Excellent welding ability, good fluidity during welding, easy to weld and easy to maintain. Widely used for electronic devices, circuit boards, electronic devices and other welding parts Notice: 1.Actual color may be slightly different from the image due to different light effect 2.Please allow 1-3cm deviation due to manual measurement Description: Colour: As shown Material: Tin copper Product weight: 300g Composition: 99.3 percent tin, 0.7 percent copper Flux-content: 1.8 percent - 2.6 percent Working temperature: 380 DegreeC-420 DegreeC Flux-data: 2.0 percent Signal: Sn99.3 Cu0.7 Melting point: 227 DegreeC Package List: 1 Roll Tin Wire Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
