300G Solder Paste Rosin Fluxes Electrical Soldering Iron Oxide Iron Welding Tip Repair Tools Soldering Iron Tip Resurrection Cream

Material: Iron box. Net content: 100g. Size: 6.56.53.2cm. Ingredients: rosin, zinc chloride, etc. Paste: yellow. Shelf life: 12 months in a cool place. Applicable to: Chip PCB motherboard welding. Description: High-quality environmentally friendly solder paste, similar in appearance to butter paste, with high bonding strength, neutral pH value, good insulation and smooth welding surface. Suitable for welding of precision electronic chips such as mobile phone PC boards. Removal of oxide film: In essence, the substances in rosin undergo a reduction reaction to remove the oxide filmPrevent oxidation: After melting, it floats on the surface of the solder to form an isolation layer, thereby preventing welding oxidationReduce surface tension: Increase welding fluidity and help weld wet welding parts.
