PROBLEM TO BE SOLVED: To supply the sufficient amount of solder, to improve jointing strength and to easily and precisely position a mounted part by installing projecting or recessed parts fitted to the recessed or projecting parts of a substrate to be jointed. ;SOLUTION: When a part terminal 3 on a mounted part 2 is arranged on a mounted board 1 through solder paste 7 applied on a land pattern on the mounted board 1, projecting and recessed parts 4 on the part terminal 3 and projecting/recessed parts 5 on the land pattern 6 corresponding to the parts are combined and are temporarily fixed at the time of positioning by a parts mounting machine. When the part terminal 3 is physically and electrically fixed on the land pattern in a reflow process, the amount of solder paste applied to the terminal where the projecting/recessed parts are made is increased by the increased amount of an effective soldering area. Thus, soldering junction strength improves and soldering reliability improves.;COPYRIGHT: (C)2000,JPO
