Feelife 100g Solder Paste Rosin Flux Scaling Powder Low Temperature Soldering Flux Lead-free Soldering Repair Paste for Electronic Component

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 film. Prevent oxidation: After melting, it floats on the surface of the solder to form an isolation layer, thereby preventing welding oxidation. Reduce surface tension: Increase welding fluidity and help weld wet welding parts
