Features

1.High Electrical Resistivity and Electrical Conductivity
Due to the addition of copper, solder wire allows the electronic components to produce relatively high electrical resistivity during the soldering process.

2.Appropriate activated rosin flux provides distinguished soldering effect, fast soldering speed, as well as extremely good fluidness.

3.High Melting Point
With high melting point, our product is ideal for the soldering of electronic equipment at high temperature. A combination of tin and copper allows this environmentally-friendly lead free solder wire to have high melting point.

4.The activated rosin flux in this product can offer superior fluxing effect.
