Patent ID: 8089007

Claim:
A printed circuit board configured to mount an electronic component, the printed circuit board comprising: a reference layer; at least one first hole defined in the reference layer and adjacent from a first pin in a first column of pins of the electronic component when the electronic component is mounted on the printed circuit board; and at least one second hole defined in the reference layer and adjacent from a second pin of the electronic component when the electronic component is mounted on the printed circuit board, the at least one second hole defined in the reference layer and opposite to the at least one first hole, wherein the second pin is in a neighboring second column of pins from the first column of pins; wherein each of the at least one first hole and the at least one second hole is not allowed to have any pin of the electronic component enter therein, a diameter of the at least one first hole is greater than a diameter of the at least one second hole causing a resistance of the at least one first hole to be less than a resistance of the at least one second hole such that a difference in current flowing through the first pin and the second pin is reduced.
