JET TYPE AUTOMATIC SOLDERING DEVICE

摘要

PROBLEM TO BE SOLVED: To obtain the fixed level of jetted molten solder, to prevent the degradation of solderability, and to allow lead-free solder to be usable in a jet type automatic soldering device used for soldering an electronic component to a printed board. SOLUTION: A nozzle 9 to jet out molten solder in a solder tank 2 containing the molten solder is provided, and a fan 6 to jet out solder from the nozzle 9 is driven by a motor 11. The level of the jetted molten solder is measured by a solder level sensor 14, and the intensity of a jet is controlled by controlling the motor 11 by a control means 15. The control means 15 controls the motor 11 based on an input signal from the solder level sensor 14 so that the solder level is fixed.
