Abstract
A printed circuit board includes 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 an electronic component, and at least one second hole defined in the reference layer and adjacent from a second pin of the electronic component. The at least one second hole is defined in the reference layer and opposite to the at least one first hole. The second pin is in a neighboring second column of pins from the first column of pins. A diameter of the at least one first hole is greater than a diameter of the at least one second hole such that a difference in current flowing through the first pin and the second pin is reduced.
