Patent ID: 7259448

Claim:
A ball grid array (BGA) package, comprising: a substrate having a plurality of contact pads on a first surface electrically connected through said substrate to a plurality of solder ball pads on a second surface of said substrate; an integrated circuit (IC) die that is mounted to said first surface of said substrate; a heat spreader that has a first surface and a second surface, wherein said first surface of said heat spreader is attached to said second surface of said substrate by an adhesive between said heat spreader and said substrate; and a ring shaped stiffener being centrally open in a first surface and a second surface, wherein said first surface of said ring shaped stiffener is attached to said first surface of said substrate; wherein said second surface of said heat spreader is capable of being coupled to a printed circuit board (PCB); wherein said IC die is mounted to said first surface of said substrate in a flip chip configuration, wherein a conductive bump on an active surface of said IC die is connected to a conductive pad on said first surface of said substrate.
