Abstract:
1. 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; arranging a plurality of electrically-conductive elements about the surface of said at least one hemi-toroidal interposer that extends radially inwardly and downwardly from an uppermost end thereof into electrical contact with at least one component located on a second surface, opposite to the first surface of said electrically insulating carrier plane; forming in said electrically-insulating carrier plane, at least one through-extending via providing an electrically conductive pad to extend through said at least one via and having portions in surface contact with first and second surfaces of said insulating carrier plane; forming a substantially central cavity in an inner wall surface of said at least one hemi-toroidal interposer for mating engagement with a solder ball, said through-extending via electrically communicating with the substantially central cavity of said interposer; and extending metallic strips of said electrically conductive elements into electrical contact with an upper pad portion of the electrically-conductive pad on the first surface of the electrically-insulating carrier plane; and the at least one component on the second surface of said insulating carrier plane being a solder ball attached to a lower pad portion of the electrically-conductive pad on the second surface of the electrically-insulating carrier plane and forming an electrically-conductive contact with the lower pad portion on the second surface of said electrically-insulating carrier plane.
