Abstract
A printed circuit board assembly having a first main printed circuit board and a connector connecting to the main board. A subsidiary board connects to the connector. The main board has a plurality of socket holes and the connector has a corresponding plurality of pins. The invention overcomes the problem of the prior art assembly, which requires a different main board to accommodate each type of connector having a different pin spacing. The main board of the invention has a combination group of four rows of holes, including a first row of holes and a third row of holes having a same first lengthwise spacing which receive the pins of one type of connector and including a second row of holes and a fourth row of holes having a same second lengthwise spacing which receive the pins of another type of connector. The first row of holes respectively having a first set of outer conductors. The first row of holes also respectively have a first set of inner conductors. Each inner conductor of the first row of holes connects to a nearest hole in the second row of holes. The third row of holes respectively have a second set of inner conductors. Each inner conductor of the third row of holes connects to a nearest hole in the fourth row of holes. The fourth row of holes respectively have a second set of outer conductors.
