PROBLEM TO BE SOLVED: To carry out soldering for a short time, as well as suppressing the cost increase of a soldering device. SOLUTION: When soldering a battery contact piece 46 to a printed circuit board 41, soldering is carried out after heating the battery contact piece 46 with big calorific capacity by a ceramic heater 67, and heating a land 54 formed on the printed circuit board 41 by a laser light L1 irradiated from a laser device 63. By this way at the time of introduction, cost increase is suppressed by heating the battery contact piece for a short time up to the melting temperature, and also by utilizing a comparatively inexpensive laser device of low output power. Since the time required for soldering is shortened, the productivity of a printed circuit board is also increased. COPYRIGHT: (C)2007,JPO&INPIT |
