Soldering Properties of Sn-Zn-X Micro Solder Powders Fabricated by Melts Dispersion Technique

Article Preview

Abstract:

Melts dispersion technique is a new process to produce solder powders in oil surroundings by the formation of molten metal’s droplets. The entire viscosity of the fluid after uniform mixture of melts and oil mainly affected the shape and size of the solder powder. The size of solder powder was increased and the irregular shape was altered into the spherical shape with increasing the fluid viscosity. The effect of alloying elements, such as Mg, Al and Ti, on Sn-Zn solder for the oxidation resistance was investigated using the solder paste mixed solder powder fabricated by melts dispersion technique at optimum conditions and RMA type flux. The oxygen concentration was reduced by the addition of alloying elements, especially, by Ti adding.
