摘要

A metallic powder which is formed by the extrusion, from multiple microscopic nozzle holes, of molten metal, which while falling and cooling changes shape from a droplet to a generally spherical shape and then solidifies, this microscopic metallic powder (around 20-90 mu m in size for example) having non-curved sections in parts of the generally curved surface and being suitable as solder.
