摘要: By preparing a package substrate which has a plurality of lands of NSMD structure, and the output wiring and dummy wiring which were connected to each of the lands, and have been arranged mutually in the location of 180° symmetry, and printing solder by a printing method to the lands after the package assembly, the variation in the height of the solder coat between lands can be reduced, and improvement in the mountability of LGA (semiconductor device) is achieved.
