Abstract

PURPOSE:To remove thoroughly the flux sticking on objects to be soldered by conveying the objects with a conveyor and subjecting the objects to flux coating, preheating, soldering, hot water washing and drying successively. CONSTITUTION:A flux is stuck in a flux coating unit 3 on objects to be soldered supplied from a feed section 2 into a conveyor 1. The excess flux is blown off by an air knife 4 and the objects are warmed in a preheating unit 5. A solder film is stuck thereon in a soldering unit 6 and thereafter the flux sticking on the objects is washed off by a hot water shower 21 from the top and air bubbled hot water from the bottom in hot water washing units 7-10. Air is ejected from above and below to blow off water drops from the objects in a rotary type air blow unit 13. The objects are then hot dried in a heating unit 14 and are cooled in a cooling fan unit 15, and thereafter the objects are taken out from a taking out section 12.
