Patent ID: 8049325

Claim:
An integrated circuit substrate, comprising: an integrated circuit chip having a plurality of electrically conductive pads on a surface thereof; a printed circuit board mounted to said integrated circuit chip, said printed circuit board comprising: an alternating arrangement of first and second electrically conductive bond fingers elevated at first and second different heights, respectively, relative to the plurality of electrically conductive pads; and a first plurality of electrically insulating pedestals supporting respective ones of the first electrically conductive bond fingers at elevated heights relative to the second electrically conductive bond fingers; a first plurality of electrical interconnects electrically connecting first ones of the plurality of electrically conductive pads to respective ones of the first electrically conductive bond fingers; and a second plurality of electrical interconnects electrically connecting second ones of the plurality of electrically conductive pads to respective ones of the second electrically conductive bond fingers; wherein said integrated circuit chip is flip-chip mounted to said printed circuit board; and wherein the first and second plurality of electrical interconnects are solder bonds.
