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