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 and extending 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, said electrically-insulating carrier plane having at least one through-extending via formed therein; extending an electrically-conductive pad through said at least one via and having portions extending in surface contact with upper and lower surfaces of said insulating carrier plane; extending metallic strips of said electrically-conductive elements into contact with an upper pad portion of the electrically-conductive pad on the upper surface of said pad, contacting the at least one component on the opposite side of said insulating carrier plane with the upper pad portion on the upper surface of said pad, and the at least one component on the opposite side of said insulating carrier plane comprising a solder ball which extends in electrically-conductive contact with a lower pad portion on the lower surface of said insulating carrier plane; configuring said at least one hemitoroidal interposer with a circular configuration, said insulating carrier plane having said through-extending via communicating with a hollow center of said interposer; and forming a plurality of slits in a sidewall of and spaced about the perimeter of said at least one interposer for dividing said at least one interposer into discrete segments, the plurality of slits configured to vent gases and pressure therethrough, the plurality of slits extending through the sidewall.
