    摘要: A printed circuit board (PCB) includes a ball grid array (BGA). The PCB further includes a first BGA pad having a circular shape, and a first via having a circular shape, where the circular shape of the first via overlaps a portion of the circular shape of the first BGA pad and is rotated diagonally relative to a center of the first BGA pad. The PCB also includes a second BGA pad having a circular shape, and a second via having a circular shape, where the circular shape of the second via overlaps a portion of the circular shape of the second BGA pad and is rotated diagonally relative to a center of the second pad, and where a center of the second via is located at a first distance from the center of the first via and at a first angle relative to an axis that crosses a center of the first via.
