Abstract
A printed circuit board includes a base formed from a plurality of woven fibers, and signal traces laid on the base. Each of the signal traces includes at least a straight line segment. The signal traces are 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.

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.
A printed circuit board, comprising:
- a base formed from a plurality of woven fibers, the fibers comprising 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 defining a rectangular area thereamong, a first angle defined by the first fiber and the diagonal of the rectangular area, and a second angle defined by the second fiber and the diagonal of the rectangular area;
- and
- a set of parallel signal traces laid on the base, each of the signal traces comprising at least a straight line segment, the straight line segments of the parallel signal traces being designed to cross the first fibers at angles larger than zero and smaller than the first angle or cross the second fibers at angles larger than zero and smaller than the second angle.
A method for producing a printed circuit board, comprising the steps of:
- providing a large base, the base defining an X-axis and a Y-axis perpendicular to the X-axis, the base formed of a set of parallel first fibers extending in the X-axis direction and a set of parallel second fibers extending in the Y-axis direction, the first fibers and the second fibers interlaced with each other;
- cutting the base into a sized base which has a size of the printed circuit board;
- and
- laying signal traces each having at least one straight line segment on the sized base in such a manner that the line segments of the signal traces mapped on the base cross the fibers of the base at angles not equal to zero degree.
