PROBLEM TO BE SOLVED: To maintain wettability of an outer periphery of a jet nozzle. ! SOLUTION: A solder jet device includes: a solder storage tank for accommodating melted solder; and a jet nozzle 24 extending in a substantially vertical direction and jetting solder fed from the solder storage tank from an upper end part 24a. A plurality of recessed grooves are formed in a substantially horizontal direction in the vicinity of the upper end part in the outer periphery of the jet nozzle 24, and thereby solder flowing out from the upper end part 24a of the jet nozzle 24 can be made residual in the recessed grooves. Accordingly, wettability is maintained in the outer periphery of the jet nozzle 24 even in the state that solder is not jetted from the jet nozzle 24. ! COPYRIGHT: (C)2015,JPO&INPIT |
