Patent ID: 7832094

Claim:
A method of operatively combining a plurality of component to form a land grid array (LGA) interposer structure, comprising the steps of providing an electrically insulating carrier plane, mounting a plurality of interposers 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; arranging a plurality of electrically-conductive elements about the surface of each said interposers so as to extend 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, forming through-extending vias in said electrically-insulating carrier plane, such that vias are each in electrical connection with respectively each said interposer; having an electrically-conductive pad extend through each said via and having portions of said interposers extending in surface contact with upper and lower surfaces of said insulating carrier plane, arranging said electrically-conductive elements comprising metallic strips to extend into contact with the pad portion on the upper surface of said pad, and positioning the component on the opposite side of said insulating carrier plane to produce a 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 BGA array.
