Claim 18:
19. A method comprising:
providing a substrate having a first surface and a second surface opposite the first surface; and
arranging interconnects on the second surface of the substrate such that the interconnects include at least one of:
first interconnects arranged in each first region of at least eight first regions of the second surface that are bounded by first radial reference lines radiating from a radial origin at the second surface and defining an acute central first angle of each first region at the radial origin, wherein each first interconnect includes a minor axis and a major axis greater than its respective minor axis, wherein the major axis of each first interconnect in its respective first region is parallel to a second radial reference line that radiates from the radial origin and through the respective first region, wherein each of the first interconnects lies on the second radial reference line that radiates through its respective region; wherein each region includes second interconnects not lying on the second radial reference line that radiates through its respective region, and wherein a major axis of each second interconnect is parallel to the second radial reference line that radiates through its respective region; or
second interconnects arranged in each second region of the second surface bounded by third radial reference lines that radiate from the radial origin at the second surface and define an acute central second angle of each second region at the radial origin, wherein the acute central second angles of the second regions sum to 360°, wherein each interconnect of a majority of the second interconnects includes a minor axis and a major axis greater than its respective minor axis, and wherein the major axis of each interconnect of the majority is parallel to a fourth radial reference line that radiates from the radial origin and through the respective second region.
