The residue-is colorless and-transparent, does not affect the detection, no-washing and excellent cleaning performance. The product has good wettability, strong resistance to dryness, a relatively long shelf life at room temperature, and a wide-range of applications. Solder tin-paste is a new type of solder material that comes with-SMT. Solder paste is a complex system that is made of a paste of solder powder, flux, and other additives.
