An exemplary printed circuit board includes a planar base, a first signal via defined in the base, a second signal via defined in the base, a first ground via defined in the base adjacent to the first signal via, a second ground via defined in the base adjacent to the second signal via, a first through hole defined in the base between the first signal via and the first ground via, and a second through hole defined in the base between the second signal via and the second ground via. |
