Abstract:
1. A module arrangement including a land grid array (LGA) interposer structure, comprising an electrically insulating carrier plane, a plurality of interposers mounted on a first surface of said carrier plane, said interposers each 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 each said interposers and extending radially inwardly and downwardly from an uppermost end thereof into electrical contact with one components located on an opposite side of said electrically insulating carrier plane, said electrically-insulating carrier plane having through-extending vias formed therein, each in electrical connection with respectively each said interposer, an electrically-conductive pad extending through each said via and having portions extending in surface contact with upper and lower surfaces of said insulating carrier plane, said electrically-conductive elements comprising metallic strips extending into contact with the pad portion on the upper surface of said pad, and the components on the opposite side of said insulating carrier plane being in contact with the pad portion on the upper surface of said pad, the components on the opposite side of said insulating carrier plane being in electrically-conductive contact with the pad portion on the lower surface of said insulating carrier plane, each said interposer having a circular configuration and an inner wall surface configured to form a nest for snap-fitting engagement with a solder ball of a LGA array.
