PROBLEM TO BE SOLVED: To reduce failure in soldering by using not only one type of jet nozzle suggested by a soldering device maker but some jet nozzles fit for each printed board, related to soldering of variety of printed boards used for an electronic equipment. SOLUTION: In this soldering method, the jet nozzle fit for soldering each printed board is selected to solder, so that failure in soldering is decreased. Related to a jet soldering bath, the jet nozzle is composed of a wave making part and a base, so that the wave making part is easily exchanged with that fit for the printed board to solder. Further, because the jet nozzle is divided into the wave making part and the base, cleaning for oxides is easily done. |
