Abstract
Abstract A socket ( 300 , FIG. 3 ) includes a housing ( 302 ) with multiple openings ( 304 ) formed in the top surface. Each opening ( 304 ) provides access to conductive contacts ( 502 , FIG. 5 ), which provide an electrical interface between a device that is inserted into the socket and the next level of interconnect (e.g., a PC board). Embedded within the socket is a conductive structure ( 310 , FIG. 3 ). In one embodiment, the conductive structure is electrically connected to one or more ground conducting contacts ( 708 , FIG. 7 ). The conductive structure includes column walls ( 312 ), which run in parallel with columns of contacts, and row walls ( 314 ), which run in parallel with rows of contacts and which intersect the column walls. In this manner, the conductive structure forms multiple chambers ( 402 , FIG. 4 ). Each signal carrying and power conducting contact is positioned within a chamber. Accordingly, the walls of the conductive structure function as a ground plane that surrounds the signal carrying and power conducting contacts.
