Abstract:
1. An interposer for interconnecting an electronic device and a circuitized substrate, said interposer comprising: a housing to be positioned on a host circuitized substrate including a plurality of host conductor pads; a first circuitized substrate positioned within said housing and including a first plurality of contact pads of a first density, selected ones of said first plurality of contact pads of said first circuitized substrate for engaging respective ones of said host conductor pads of said host circuitized substrate; and a second circuitized substrate positioned on said first circuitized substrate and electrically coupled thereto forming an integral unit, said second circuitized substrate for engaging an electronic device including a plurality of contact sites thereon of a second density different than said first density of said first plurality of contact pads of said first circuitized substrate, said second circuitized substrate including a first plurality of sculpted contact members of a density similar to said second density of said contact sites of said electronic device, selected ones of said first plurality of sculpted contact members of said second circuitized substrate for engaging respective ones of said contact sites of said electronic device when said electronic device is positioned on said second circuitized substrate, said first circuitized substrate including a plurality of conductive lines therein which intercouple said selected ones of said first plurality of contact pads of said first circuitized substrate to said selected ones of said first plurality of contact members of said second circuitized substrate.
