Production of Lead-Free Solder Powder by Atomization Process

Phairote Sungkhaphaitoon

Abstract


This research article studied the production of lead-free solder powder by atomization process.         From literature review, it was found that the lead-free solder powders can be produced by ultrasonic atomization, centrifugal atomization, and hybrid atomization. Each process produces different metal powders. Hybrid atomization is the most suitable process to produce the lead-free solder powder because this process provides metal powder with a smaller median particle size and higher production yield as compared to              the other processes. The shapes of metal powders produced from these three processes depend on              the amount of oxygen in the process. Metal powders produced at low oxygen and under inert gas atmosphere form spherical shape with low oxygen content on the metal surface. Therefore, it is suitable to be used in electronic and electric industries.
