PROBLEM TO BE SOLVED: To provide a method for suppressing the production amount of oxides of melt solder in a flow soldering apparatus. SOLUTION: A box 14 for cutting off air is provided at the portion of a drive shaft 12 to rotate a rotary blade 13 for solder transfer by a pressure for generating a jet flow is provided in a solder tank 5 for soldering by the flow soldering apparatus. The production amount of oxides of the melt solder is suppressed by making the rotating part of the drive shaft not come into contact with the surface of the melt solder. COPYRIGHT: (C)2004,JPO |
