Effect of Oxidation Rate of Tin Powder in Solder Paste on Cold Soldering

Solder paste is a mixture of tin powder particles and flux paste. The flux in the solder paste has four static properties and four dynamic properties. The four dynamic properties of the industry is often referred to as flux to remove the oxide layer, prevent re oxidation, reduce the surface tension of liquid solder
