Soldering is a process that create electrical, mechanical, or thermal bonds using heat, filler materials and flux. The heat reflows the filler material and the flux cleans the oxides off the surfaces that will be joined together.
Once the heat is removed, the solder solidifies to create a bond. Although this sounds simple, there are many things to consider when choosing the right materials for your process. We use high purity tin ingot, no recycle materials, then solder joint is full, good light reflection and forming. brightness.
