Abstract
According to one embodiment, a printed circuit board includes a substrate and a shared pad group provided on the substrate and including a plurality of shared pads. The shared pads include a first area, a second area smaller in size than the first area, a port of which is overlap the first area and an other port of which is located to protrude from the first area to a side of another one of the shared pads, and a second side edge located on a side of another shared pad. The second pad side edge includes a first side edge defining the first area, a second side edge defining the second area and displaced on a side of another shared pad with respect to the first side edge, and a sloping side edge connecting the first side edge and the second side edge to each other.

A printed circuit board comprising:
- a substrate;
- and
- a shared pad group provided on the substrate and including a plurality of shared pads,
- the plurality of shared pads each comprising a first area, a second area smaller in size than the first area, a port of which is located to overlap the first area and an other port of which is located to protrude from the first area to a side of another one of the shared pads, a first pad side edge extending in a first direction and defining the first area and the second area, and a second pad side edge extending in a second direction intersecting the first direction and defining the first area and the second area,
- the first pad side edge including a first side edge defining the first area, a second side edge defining the second area and displaced on a side of another shared pad with respect to the first side edge, and a sloping side edge connecting the first side edge and the second side edge to each other.
A printed circuit board comprising:
- a substrate;
- and
- a pad group provided on the substrate and including a first pad, a second pad aligned with the first pad in a first direction and a third pad aligned with the first pad in a second direction that intersects the first direction,
- the first pad and the second pad being each formed into an n-polygonal shape (n is six or more) and include first side edges opposing each other with a gap therebetween and second side edges opposing each other with a gap therebetween,
- a distance between the first side edges being greater than a distance between the second side edges,
- the second side edge of the first pad being located adjacent to the second pad as compared to than the first side edge of the first pad.
