Ball grid array integrated circuit package which employs a flip chip integrated circuit and decoupling capacitors

Abstract

A ball grid array to integrated circuit interconnection. The interconnection includes a ball grid array substrate having a first surface and a second surface. The first surface comprising a plurality of substrate interconnection conductive pads. A power supply via connects a power supply conductive pad of the first surface to a first conductive area on the second surface. A ground via connects a ground conductive pad of the first surface to a second conductive area on the second surface. A decoupling capacitor connected between the first conductive area and the second conductive area. The interconnection further comprises an integrated circuit comprising a plurality of integrated circuit conductive pads. A plurality of smaller solder balls interconnect at least one of the integrated circuit conductive pads to at least one of the substrate interconnection conductive pads. A circuit board substrate is electrically interconnected by larger solder balls to the ball grid array substrate.
