Patent ID: 7105918

Claim:
An electronic device package, comprising: an interposer comprising: a substrate having a first side and an opposing, second side and comprising a flexible core material; at least one flexible solder pad element on the first side of the substrate, wherein the at least one flexible solder pad element comprises a discrete protrusion of the flexible core material extending in a substantially perpendicular direction outwardly from the first side of the substrate and a solder pad on a tip of the discrete protrusion; a conductive via extending from the solder pad of the at least one flexible solder pad element to the second side of the substrate; and a conductive routing layer on the second side of the substrate having at least one bond pad electrically connected to the solder pad of the at least one flexible solder pad element by the conductive via; and at least one semiconductor die mounted to and electrically connected to the interposer.
