Abstract
(EN)
[Problem] To obtain a solder powder having an average particle diameter of 0.05 µm or more but less than 3 µm. [Solution] A solder powder having an average particle diameter of, for example, 0.05 µm or more but less than 3 µm is obtained by using a process for solder powder production which comprises a step in which a solid or liquid metal, a nonaqueous solvent, and balls for pulverization which have a diameter of 0.05-5 mm are introduced into a vessel to obtain a mixture, a step in which the mixture is heated to 150ºC or higher and stirred, a step in which the balls for pulverization are separated from the stirred mixture to obtain a mixture of a solder powder and the nonaqueous solvent, and a step in which the solder powder/nonaqueous-solvent mixture is subjected to solid/liquid separation to obtain the solder powder.

L'invention a pour but d'obtenir une poudre de brasage ayant un diamètre moyen de particule de 0,05 µm ou plus mais de moins de 3 µm. A cet effet, selon l'invention, une poudre de brasage ayant un diamètre moyen de particule par exemple de 0,05 µm ou plus mais de moins de 3 µm est obtenue à l'aide d'un procédé de fabrication de poudre de brasage qui comprend une étape dans laquelle un métal solide ou liquide, un solvant non aqueux et des billes de pulvérisation qui ont un diamètre de 0,05-5 mm sont introduits dans un récipient pour obtenir un mélange, une étape dans laquelle le mélange est chauffé à 150°C ou à une température supérieure et agité, une étape dans laquelle les billes de pulvérisation sont séparées du mélange agité pour obtenir un mélange d'une poudre de brasage et du solvant non aqueux et une étape dans laquelle le mélange poudre de brasage/solvant non aqueux est soumis à une séparation solide/liquide pour obtenir la poudre de brasage.
