Patent ID: 7331796

Claim:
A land grid array (LGA) interposer structure, comprising an electrically insulating carrier pad, at least one interposer mounted on a first surface of said carrier pad, said interposer selectively having a hemi-toroidal, conical, dome-shaped conic section, generally cylindrical or hemi-spherical configuration in transverse cross-section and being constituted of a dielectric elastomeric material; a plurality of electrically-conductive elements being arranged about the surface of said at least one hemi-toroidal interposer and extending radially inwardly and downwardly from an uppermost end thereof into electrical contact with at least one component located on an opposite side of said electrically insulating carrier pad, said at least one component comprising at least one hemi-toroidal interposer mounted on said opposite side of said carrier pad and which is identical to and in an inverted relationship with said first-mentioned at least one hemi-toroidal interposer, an electrically-conductive solder pad member extending through at least one via and having portions extending in surface contact with upper and lower surfaces of said insulating carrier pad, said at least one hemi-toroidal interposer and said at least one inverted hemi-toroidal interposer being at least partially located on, respectively, the upper and lower surface of said insulating carrier pad, whereby the electrically-conductive elements are in contact with the respective surfaces on said solder pad.
