Abstract:
1. A ball grid array (BGA) package, comprising: a flexible substrate that has first and second surfaces, the substrate having a plurality of solder ball contacts on said first surface for an attachment to a printed circuit board (PCB) and having an opening therein that is open at said first and second surfaces; a rigid stiffener that has a planar first surface coupled to said second surface of said substrate so that said first surface of said stiffener is substantially coplanar with said second surface of said substrate and covers said opening, and wherein an area of said first surface of said stiffener is less than an area of said second surface of said substrate; and a thermal connector that has first and second surfaces, wherein said second surface of said thermal connector is coupled to said first surface of said stiffener through said opening, and wherein said first surface of said thermal connector is capable of attachment to the PCB when the BGA package is mounted to the PCB.
