Abstract

A ball grid array package and low cost method for manufacture of the same is disclosed herein. The ball grid array package includes a thermal conductor which is a linearly co-extensive outer layer of an interconnection substrate and forms the outer surface of the ball grid array package. An integrated circuit chip is positioned on the underside of the package in a well region. The well region is either formed directly in the interconnection substrate or is formed by the application of a dam. The well region is then filled with an insulating encapsulant material to a predetermined level.
