of a board for more than two inches of cumulative distance. The length of trace segments that are
parallel to the edge of a board should be minimized as much as possible. Traces should be at an
angle of at least 10º to a board edge. This is to reduce the effects of PCB fiber weave on board
impedance and propagation velocity on differential traces (see Figure 13).
