PURPOSE:To prevent sticking of solder to both end edges of jigs for conveyance by conveying parts to be soldered in the tight contact state by the jigs for conveyance which are held in place between rubber belts installed above and below. CONSTITUTION:The parts 1 to be soldered are attached to the jigs 2 for conveyance and are fed between the conveyor belts installed above and below in such a manner that the conveyance faces of the rubber belts 11 and 12 face each other. The parts pass over a solder tank 9 while the parts are sandwiched in an arrow B direction by driving wheels 13 and 14. The parts are then soldered by solder 10 blown up from the tank 9. The solder 10 blown up from the tank 9 sticks to the jigs 2 at the same instant when the parts 1 are soldered but both end edges of the jigs 2 are held in place between the belts 11 and 12 so as to tight contact therewith and therefore the solder 10 does not flow into the sandwiched parts. The parts where the solder corresponding to the sandwiching width of the belts 11, 12 at both end edges of the jigs 2 are not stuck are thus made to soldered parts 1 by the jigs 2.
