Abstract:
1. An electronic assembly comprising: a die; a motherboard; a package substrate between the die and the motherboard and having a first surface adapted to receive the die on a die receiving portion thereof, and a second surface disposed opposite the first surface, wherein the die receiving portion includes an outline defining a die shadow region in a direction from the first surface to the second surface; and a socket contact region between the package substrate and the motherboard, wherein the die shadow region includes a socket central cavity substantially surrounded by the socket contact region in a first direction, and the socket central cavity borders the motherboard in a second direction perpendicular to the first direction, wherein between the package substrate and the motherboard is at least one socket cavity external to the socket contact region and outside of the die shadow region, wherein the at least one socket cavity borders the socket contact region in a first direction and borders the motherboard in a second direction perpendicular to the first direction, wherein the substrate includes a plurality of droop capacitors supported by the second surface, wherein the plurality of droop capacitors includes a first capacitor within the socket central cavity and a second capacitor positioned within a first socket cavity of the at least one socket cavity external to the socket contact region, wherein the motherboard includes a plurality of board-side capacitors corresponding to the plurality of droop capacitors.
