PURPOSE:To realize saving, etc., the consumption of a solvent by placing both side parts of a carrying conveyor in a vapor tank by providing the difference of height, and supporting a printed circuit board in an inclined state in the vapor tank. CONSTITUTION:In a vapor tank 11, both side chains 22, 23 for supporting and carrying the printed circuit board P are provided by providing the difference of height. Accordingly, the board P is supported in an inclined state by supporting parts 24, 25 of both sides and carried in the vapor tank 11 In this case, the lead of each parts loaded on the board P is heated by the vaporized latent heat of a vapor phase 19, and soldered, and also the vapor phase 19 is condensed. Since the board P is inclined, a condensate flows down into a solvent tank 12 along the inclined surface, and collected. According to this method, the consumption of the solvent can be saved, and also the condensation efficiency can be improved. |
