Abstract: A solder drawing member (402) is detachably attached on the outer side of a jet nozzle (303) that jets molten solder pumped from a solder tank (102) storing the molten solder. The solder drawing member (402) is made of a material having higher wettability to the molten solder than the surface material of the jet nozzle (303). Thus a force of separating the solder from a point to be soldered can be increased by a surface tension of the molten solder flowing on the solder drawing member (402), thereby reducing bridge phenomena and icicle phenomena.

Abstract: A first holding frame of a component holding unit is allowed to hold a plurality of components composing a first assembly and a second holding frame of the component holding unit is allowed to hold a plurality of components composing a second assembly which is to be mounted on the first assembly. The first assembly held onto the first holding frame and the second assembly held onto the second holding frame are assembled by an assembly work unit. The second holding frame is allowed to reciprocate towards the first holding frame to pass the second assembly from the second holding, frame to the first holding frame. Thereafter, the first assembly and the second assembly which are held onto the first holding frame are assembled and coupled together by the assembly work unit.
