Patent ID: 8752284

Claim:
A method of producing a land grid array (LGA) interposer structure, comprising: mounting at least one interposer on a first surface of an electrically insulating 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; positioning a plurality of electrically-conductive elements about the surface of said at least one hemi-toroidal interposer that extend 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; mounting said at least one component comprising at least one hemi-toroidal interposer mounted on said opposite side of said carrier plane and which is identical to and in an inverted relationship with said first-mentioned at least one hemi-toroidal interposer; forming at least one through-extending conductive via in said electrically-insulating carrier plane only extending through the carrier plane, and the at least one through-extending conductive via not formed by or extending through the said first-mentioned at least one hemi-toroidal interposer and said further at least one inverted hemi-toroidal interposer; and forming electrical connections between said first-mentioned at least one hemi-toroidal interposer and said further at least one inverted hemi-toroidal interposer, wherein said electrically-conductive elements comprise metallic strips, and the electrical connections being formed using said electrically-conductive elements comprising metallic strips through the at least on through-extending conductive via.
