Patent ID: 7709943

Claim:
An electronic module comprising: a first integrated circuit (IC) package layer including a first plurality of I/O pads; an interposer layer including a plurality of angularly-depending leads, wherein at least one of the leads comprises a terminal configured to route an electrical signal to at least one I/O pad of the first plurality of I/O pads; a second IC package layer including a second plurality of I/O pads; and an interface printed circuit board (PCB) including: a plurality of conductive traces configured to route electrical signals from a third plurality of I/O pads to at least some of the second plurality of I/O pads and at least some of the first plurality of I/O pads; and at least one castellation connection point on a peripheral edge of the interface PCB; wherein the angularly-depending leads have sufficient lengths and are appropriately angularly disposed with respect to the plane of the interposer layer to engage the at least one castellation connection point to form an electrical connection.
