Synthesis of Lead-Free Solder Particles Using High-Speed Centrifugal Atomization

We investigated the relationships between the centrifugal force and the disc size and rotation speed during the production of ne particles. In this study, an empirical formula was developed with the goal of obtaining an average particle size of D50. Moreover, particle production was performed at a disc rotation speed of at least 100,000 rpm, which was… (More)
