Abstract
A land grid array (LGA) interposer structure, including an electrically insulating carrier plane, and interposer groupings of different height being mounted on a first surface of said carrier plane. Each interposer possesses a hemi-toroidal configuration in transverse cross-section and is constituted of a dielectric elastomeric material. A plurality of electrically-conductive elements are arranged about the surface of each hemi-toroidal interposer and extend radically inwardly and downwardly from an uppermost end thereof into electrical contact with at least one component located on an opposite side of the electrically insulating carrier plane.
