<p>PURPOSE:To enable an insertion-type component such as a fuse holder or the like large in heat capacity to be easily and surely connected to a wiring board by soldering. CONSTITUTION:Cream solder is applied onto an insertion-type component mounting electrode 11 and a chip-type component mounting electrode 13 of a wiring board 10 through printing. A terminal 15a of a fuse holder 15 is inserted into a through-hole 12 provided to the insertion-type component mounting electrode 11, and a chip capacitor 16 is placed on the chip-type component mounting electrode 13. Then, cream solder applied onto the wiring board 10 is molten by reflow soldering to feed a part of solder 14a into the through-hole. Moreover, the rear side of the wiring board 10 is brought into contact with a solder tank to supply solder into the through-hole. As mentioned above, solder is fed in two steps to a wiring board from both above and below, whereby the through- hole is filled with solder, and a fuse holder is surely connected to a wiring board by soldering.</p> |
