A printed circuit board having one or more holes that are controllably drilled to extend into the printed circuit board substrate to a predetermined depth intermediate first and second faces. A mechanical locating pin is received into each of the one or more holes to mechanically align a first component for electronically interfacing with the printed circuit board substrate. A second component is installed on the second face directly opposite of the one or more holes such that the second component is in electronic communication with conductive traces or interconnects formed on the second face directly opposite of the hole.
