Patent ID: 7374428

Claim:
A land grid array (LGA) interposer structure, comprising an electrically insulating carrier plane, at least one interposer mounted on a first surface of said carrier plane, 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 plane, said electrically-insulating carrier plane having at least one through-extending via formed therein, an electrically-conductive pad extending through said at least one via and having portions extending in surface contact with the upper surface of said insulating carrier plane, said electrically-conductive elements comprising metallic strips extending into contact with the pad portion on the upper surface of said pad, wherein a plurality of said interposers of essentially conical or dome-shaped conic sections are arranged in groupings, each said grouping having the electrically-conductive elements of each of said interposers joining proximate said at least one via in said insulating carrier plane to form a common connection to a single input/output contact at a lower surface of said insulating carrier plane.
