PURPOSE:To prevent a solder from adhering to unnecessary parts by holding the unnecessary parts for solding by a metallic radiating jig of high heat conductivity when a connecting terminal such as a plug installed on a printed wiring board is soldered. CONSTITUTION:A plate terminal 12 is inserted into hole 16 formed on a printed wiring board and the terminal end is caulked to connect electrically to a pattern 18 formed on the side of the printed wiring board 10. When the connected part between the pattern 18 and the terminal 12 is soldered, the terminal 12 are soldered by a soldering iron 22 and a soldering stick 24 after the unnecessary parts 12 for soldering is held by a radiating jig 20 of high heat conductivity such as Aluminium. In this case, by fixing radiating jigs 32, 34 (the second) to shafts 36, 38 and transfering to the opposite direction by air cylinders 40, 42 the unnecessary parts for soldering is strongly held and radiated to prevent a molten solder from adhering. |
