    摘要: A soldering is performed in such a manner that two solder portions having different melting points are put between a metallization on a substrate for joining and a part. The chip portion having a higher melting point is made thicker than a solder foil portion having a lower melting point. Initially, the part is held to the metallization by the solder chip having the higher melting point. The solder foil having the lower melting point is first melted in such a state and, after that, the solder chip having the higher melting point is melted. By such a soldering method, a reliable soldering can be performed, without causing a void on the undersurface of a part joint section, by one soldering operation, so that a presoldering operation becomes unnecessary.

    摘要: A vapor tank for processing a product by heating the same through exposure to vapor serving as a heat transfer medium. The vapor tank includes at least one partition wall separating a vapor chamber filled with vapor and a heating chamber for processing the product by heating the same for supplying a sufficient saturated vapor to the product. The partition wall is formed with openings for allowing the saturated vapor to be injected therethrough from the vapor chamber into the heating chamber where the product is enveloped by the saturated vapor. The vapor tank is provided with a recovery device for recovering the vapor flowing out of the tank through an inlet and an outlet for introducing and discharging the product into and out of the tank with a high degree of vapor recovering efficiency and with a minimum loss of energy. The vapor tank is also provided with a mechanism for externally supplying air currents to prevent the vapor from flowing out of the tank through the inlet and the outlet.
