Title: Wave soldering device
Inventor: GOTO TETSUYA
IPC: B23K1/08
Filed: 1999-05-27
Abstract: PROBLEM TO BE SOLVED: To obtain a wave soldering device which can suppress oxidation of molten solder to a minimum. SOLUTION: In a wave soldering device, molten solder J stored in a bath is jetted out of nozzles 22 formed in a wave forming plate 21 for feeding. The lower end of the wave forming plate 21 is extended so as to reach a bath liquid surface J' of the melted solder J. The part of the wave forming plate 21, which reaches the bath liquid surface, is formed into a warped shape 21c recessed in an approximately aslant downward. With this constitution, since the molten solder J jetted out of the nozzles 22 is made to flow back into the bath while being guided by the wave forming plate 21, the falling speed of the solder can be reduced in comparison with the conventional constitution and the quantity of air caught in by the solder at flowing in can be reduced. As a result, oxidation of the melted solder can be suppressed.
