Abstract
A soldering apparatus includes a solder wave shape forming means for melting solder and forming a solder wave shape, and a separating agent dusting means for dusting solder oxides with a separating agent which separates solder and solder oxides. The separating agent is any one selected from the group consisting of offal, cereal grain or flour, bean flour, seed grain or flour, soybean-cake flour, and peanut hull flour, or a combination thereof, as well as an agent and a method of separating solder and solder oxides.
