Abstract
An electronic assembly includes a copper pillar attach substrate that has a dielectric layer and a solder resist layer overlying the dielectric layer. The solder resist layer has a plurality of solder resist openings. A plurality of parallel traces are formed on the dielectric layer. Each trace has a first end portion, a second end portion and an intermediate portion. The first and second end portions of each trace are covered by the solder resist layer and the intermediate portions are positioned in the solder resist openings. Each of the intermediate portions has at least one conductive coating layer on it and has a height measured from the dielectric layer to the top of the topmost conductive coating layer that is at least as great as the solder resist layer thickness.
