Abstract: The invention provides an industrially efficient, low-cost, mass-production system for the process of producing fine solder powders using an in-oil atomization method wherein solder is melted in a heated dispersion medium for fine granulation. Molten solder melted in a solder melting tank and a mixture of a particle dispersion medium and a particle coalescence-preventing agent, prepared in a dispersion medium heating tank, are fed to a fine-granulation machine, in which dispersion energy is applied to obtain a dispersion of molten solder particles. The dispersion is processed in a solidifier-by-cooling to obtain a dispersion of solid solder particles, which is processed in a solid-liquid separator to separate the solid solder particles. The solid solder particles are washed and dried to obtain fine powders. The respective devices at these steps are connected together by way of piping, so that fine solder powders can continuously be produced.
