Abstract:
An interposer for making connections to electrical contact pads on a surface of a microelectronic element defining holes therein, the interposer comprising:(a) a body having a first major surface, said body having horizontal directions parallel to said first major surface, and vertical directions perpendicular to said first major surface; (b) a plurality of conductors in said body; and (c) a plurality of contacts on or above said first major surface, each said contact being permanently joined to one said conductor and extending radially outwardly from the conductor, each said contact having a periphery remote from the conductor and a central portion attached to the conductor; each said contact being adapted to deform so that the periphery of the contact will contract radially inwardly toward the central portion of the contact in response to urging said periphery of the contact against a contact pad and inserting the central portion of the contact into the hole defined by the contact pad; whereby said contacts will wipe the contact pads of the microelectronic element when the microelectronic element is juxtaposed with said first surface and forced toward said body.
