Patent ID: 7070419

Claim:
An electrical connector for electrically connecting to contacts of a land grid array formed on an electronic component, the connector comprising: a dielectric layer including opposing first and second surfaces; and a plurality of circumferential contact elements, pre-formed in an array in a sheet of conductive spring material, the circumferential contact elements including generally opposed elastic portions that are displaced outwardly from the sheet and extending inwardly toward a center of the circumferential contact elements, the sheet being bonded to the first surface such that the elastic portions extend outwardly above the first surface of the dielectric layer, each of the circumferential contact elements comprising a base portion of conductive material that is singulated from the base portions of adjacent ones of the circumferential contact elements, and the elastic portions of conductive material are formed integrally with the base portion, the plurality of circumferential contact elements comprising a first group of contact elements and a second group of contact elements, the first group of contact elements having an operating property based on a formation thereof in the sheet that is different than an operating property of the second group of contact elements.
