Abstract:
A wave soldering system for soldering on a work-piece by a wave molten solder, the system comprising:a solder bath for storing a molten solder therein;a wave device equipped with the solder bath for jetting the molten solder as the wave molten solder from the solder bath onto the work-piece;a transfer unit disposed above the solder bath for transferring the work-piece while bringing the work-piece into contact with the wave molten solder;a displacement detecting device for detecting a warp amount of the work-piece which is caused by heat, the warp amount being detected from displacement amounts of a plurality of points of the work-piece in a height direction perpendicular to a work-piece surface; andan adjustment device for controlling an immersion depth of the work-piece into the wave molten solder to be constant by adjusting one of a height position of the work-piece and a wave height of the wave molten solder in the height direction based on the warp amount of the work-piece.
