Title: Jet local soldering machine
Inventor: SATO SHIN
IPC: H05K3/34
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To prevent an oxide film produced on the surface of melted solder from sticking to a printed wiring board by holding inside a nozzle a tubular mesh filter with its top closed and the distance between the filter and the inner wall face of the nozzle controlled to a specified value or less. SOLUTION: A tubular mesh filter 48 with its top closed is held inside a nozzle 18. The mesh filter 48 is made of, for example, a stainless steel mesh in a rectangular box shape, and the lower part of the mesh filter is protruded downward to a level lower than the nozzle 18 and widened slantingly and outward like a skirt. When a jet pump 34 located under the point of soldering of a printed wiring board is started, solder goes up a solder path 36 and jets out of the nozzle 18. At this time, any oxide film in the mesh filter 48 is caught by the top face of the mesh filter 48. Any oxide film present between the nozzle 18 and the mesh filter 48 sticks to the outer face of the mesh filter 48 and the inner face of the nozzle 18 when the surface of solder liquid goes up. For the reason, the oxide films are prevented from sticking to the printed wiring board.
