Land grid array (lga) interposer utilizing metal-on-elastomer hemi torus and other multiple points of contact geometries

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 interposers and extending radially inwardly and downwardly from an uppermost end thereof into electrical contact with components located on an opposite side of said electrically insulating carrier plane, said components comprising interposers mounted on said opposite side of said carrier plane and being identical to and in an inverted relationship with said first-mentioned interposers said interposers comprising a linear bar mounted on said insulating carrier plane on opposite sides thereof, and a plurality of electrically-conductive strips extend from the uppermost to the lowermost ends of said interposers in mutually electrical connection through at least one electrically-conductive via formed in said insulating carrier plane.
