Patent ID: 7973244

Claim:
A printed circuit board, comprising: a base formed from a plurality of woven fibers; and signal traces laid on the base, each of the signal traces comprising at least a straight line segment, the signal traces laid on the base in such a manner that the line segments of the signal traces mapped on the base cross the fibers at angles not equal to zero degrees; wherein the fibers comprise a set of parallel first fibers, and a set of parallel second fibers perpendicular to and interlaced with the set of first fibers, two adjacent first fibers and two adjacent second fibers define a rectangular area, a first angle is defined by the first fiber and the diagonal of the rectangular area, and a second angle is defined by the second fiber and the diagonal of the rectangular area, the angle defined by each line segment of each signal trace and each corresponding fiber is not smaller than half of the smaller of the first and second angles, each line segment of the signal trace mapped on the base crosses the diagonal of the rectangular area at angles not equal to zero degrees; and substantively no line segments are present on the board which are coincident with the fibers and the diagonal of the rectangular area.
