Patent ID: 7491068

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 an electrically conductive pad, said electrically-insulating carrier plane having at least one through-extending via formed therein; said 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 an upper surface of said pad, wherein a plurality of said interposers of essentially conical or dome-shaped conic sections are arranged in paired groupings of predetermined numbers of said interposers, 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 and contacting said pad to form a common connection at the lower surface of said insulating carrier plane, wherein each of the interposers in one grouping differs in height from the interposers in the other grouping.
