ABSTRACT:
A ball grid array package provides conductive paths between terminals and a semiconductor chip through via-hole plugs formed in a circuit board, and the via-hole plugs are covered with a rigid plate before sealing the semiconductor chip in synthetic resin so as to prevent the via-hole plugs from penetration of the synthetic resin.
