ABSTRACT:
A face-mounting type memory module board wherein the number of through-holes is reduced by a large margin in order to improve the reliability of the board. V.sub.CC and V.sub.SS plates which have heretofore been provided inside a multi-layer wiring board are disposed on the reverse surface of a single-layer wiring board, and other wirings are disposed on its obverse surface by making use of a fine process, thereby greatly reducing the number of through-holes required.
