Abstract:
1. An electronic interconnection structure for electrically interconnecting a first group of electrical terminals with a second group of electrical terminal at a controlled characteristic impedance, the interconnection structure comprising: a plurality of signal conductors including a first signal conductor, each signal conductor having a first end and a second end, the signal conductors being arranged in a fixed spatial relationship to each other such that an arrangement of first ends collectively form a coarser pitch terminal group, and such that the signal conductors converge from the coarser pitch terminal group to a finer pitch terminals group formed by the second ends of the signal conductors, wherein the coarser pitch terminals are exposed, and spatially arranged to provide simultaneous access to all coarser pitch terminals; a first dielectric layer having a tapered thickness; a first signal conductor disposed on a first surface of the first dielectric layer and having a tapered width; and a first conductive grounding layer disposed on a surface of the first dielectric layer opposite the first surface.
