Product description:
Good quality environment-friendly soldering paste is similar to butter paste in appearance, with high bonding strength, neutral PH value, good insulation, and smooth welding surface. It is suitable for soldering of precision electronic chips such as mobile phone PC boards.
Removal of oxide film: in essence, the substance in rosin undergoes a reduction reaction to remove the oxide film
Oxidation prevention: after melting, it floats on the surface of solder to form an isolation layer, thus preventing oxidation of welding
Reduce surface tension: increase soldering fluidity, which is helpful for soldering wet weldments
