PURPOSE:To prevent solder from flowing into a hole, by inserting a pin which has a greater external diameter than the internal diameter of a stud and is tapered at the top at a specific angle into the stud in contact with the stud from the other surface of a plate, and carrying out soldering. CONSTITUTION:The stud (a) is inserted into a holed printed plate (b) from one surface and soldered. At this time, the tapered pin (d) which has the greater external diameter than the internal diameter of the stud (a) and is tapered at the top at the specific angle is inserted from the other surface of the plate (b) in contact with the stud (a) by a spring (f) provided to a base (e). Thus, the part a-2 of the stud (a) is heated and pressurized by a heating chip to perform the soldering. |
