SOLDER JETTING NOZZLE AND SOLDERING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a solder jetting nozzle capable of accurately and correctly jetting a predetermined quantity of molten solder to a soldering portion such as a minute distance or a minute soldering portion. SOLUTION: The nozzle comprises a base portion 82 detachably attached on a nozzle attaching member 67 in a solder bath 57 and used for supplying the molten solder 5 to a solder flow passage 83 provided in its inside; a nozzle portion 85 formed integrally with one end of the base portion 82 and having a penetrating nozzle hole 86 communicating to the solder flow passage 83; and a solder reservoir concave portion 87 formed on the tip of the nozzle portion 85 so as to communicate to the nozzle hole 86 and have a predetermined depth and an inner diameter larger than the diameter of the nozzle hole. The device spot-jets the predetermined quantity of the molten solder 5 reserved in the solder reservoir concave portion 87 by a jet pressure generated in the solder bath 57 to execute soldering.
