Abstract: PURPOSE:To improve the reliability and efficiency of soldering by providing vapor vessels for the 1st and 2nd inert liquids respectively having the b.p. in a specific range and communicating the vessels in a connecting part provided with a condenser coil. CONSTITUTION:The 1st vapor vessel 1 for the inert liquid having the b.p. which does not exceed the m.p. of cream solder 5 is provided and the 2nd vapor vessel 2 for the inert liquid having the b.p. above the m.p. of the solder 5 are disposed. The communicating part of the condenser coil 3 is further constituted at the boundary between the vessels 1 and 2. A work 7 on which electronic parts 6 are placed is carried by a belt 8 into the vessel 1 and the heated and satd. vapor 11 of the inert liquid 9 melts a flux and activates the joint material. The solder 5 is then melted by the satd. vapor 14 of the vessel 2 to joint a substrate 4 and the parts 6. The coil 3 prevents the mixing of the satd. vapors 11, 14. The reliability and efficiency of soldering are improved by the above- mentioned method.
