  • Patent number: 6257480
    Abstract: In a jet soldering method, a substrate is held by an actuator and pre-heated by a pre-heater. The pre-heater has a shield member or the substrate is swung to equalize temperature distribution in the substrate. The substrate is then transferred over a primary jet soldering bath while dipping a treatment surface of the substrate in a primary solder jet, so that solder stick to the treatment surface of the substrate. Then, the substrate is transferred over a secondary jet soldering bath while dipping the treatment surface in a secondary solder jet, so that the solder sticking to the substrate is shaped. The transfer conditions of the substrate are differentiated between transfers over the primary jet soldering bath and the secondary jet soldering bath.
