摘要: A circuit board is described where the fiberglass fiber pattern as been modified than what found in conventional FR4 boards. In one embodiment, sets of fibers are disposed a zig-zag or herringbone manner. use, when pair conductors onto into board, material surrounding first conductor tends to be similar second conductor. Doing so may reduce differential common mode conversion between conductors.
