In the conventional configuration, surface mounting type semiconductor devices having various outer dimensions and lead pin pitches are individually mounted, so that the outer dimensions of the printed circuit board may vary depending on the number of surface mounting type semiconductor devices to be mounted. Because of the area, it is necessary to separate each package when evaluating the solder connection part such as solder wettability. In addition, there is a problem in that the printed circuit board has to be formed for each of various external dimensions and lead pin pitches of the surface mount type semiconductor devices, which causes a cost increase.
