Method of producing a land grid array interposer structure

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, and the at least one component on the opposite side of said insulating carrier plane being in contact with the upper pad portion on the upper surface of said pad, the at least one component on the opposite side of said insulating carrier plane being in electrically-conductive contact with a lower pad portion on the lower surface of said insulating carrier plane;
• configuring said at least one hemi-toroidal interposer with a circular configuration;
• forming a nest in an inner wall surface of said at least one toroidal interposer for snap-fitting engagement with a solder ball, said insulating carrier plane having a through-extending via communicating with a hollow center of said interposer;
• and
• forming at least one slit in a sidewall of said interposer to vent gases and pressure therethrough.
