Abstract:
1. A method of operatively combining a plurality of components to form a land grid array (LGA) interposer structure, comprising the steps of providing an electrically insulating carrier plane, mounting at least one interposer 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; arranging a plurality of electrically-conductive elements about the surface of said at least one hemi-toroidal interposer so as to 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 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 via in said electrically-insulating carrier plane, forming electrical connections between said electrically-conductive elements comprising a plurality of metallic strips and said first-mentioned at least one hemi-toroidal interposer and said further at least one inverted hemi-toroidal interposer, and extending each said metallic strips unitarily from the uppermost end of said at least one hemi-toroidal interposer on the first surface of said carrier plane linearly through said via to the lowermost end of the at least one inverted hemi-toroidal interposer on the opposite side of said carrier plane.
