| description | PROBLEM TO BE SOLVED: To eliminate a soldering defect and to enhance the yield of a reflow soldering operation by a method wherein the position of the center of gravity of a connector body is formed so as to be put aside to the side of a part from which a lead is derived. SOLUTION: A printed-circuit board 1 is set in a printed-circuit board positioning part 9A. Then, when a connector body part 6 is dropped into a connector positioning recessed part, a lead 7 at a connector 5 is set in a state that it is brought into contact with a solder paste on a foot pattern 4 at the printed-circuit board 1. At this time, since the connector body part 6 is set to a state that the position of its center of gravity is formed so as to be put aside to a side from which the lead 7 is derived, it is set in a state that the lead 7 is pressed to the foot pattern 4. After that, a reflow soldering operation is performed. Thereby, it is possible to restrain the lead 7 from being levitated from the foot pattern 4 at the printed-circuit board 1 in the halfway part of the reflow soldering operation. A soldering defect is eliminated, and the yield of the reflow soldering operation can be enhanced. |
