1. An electrical apparatus comprising:
a printed circuit board including:
a first surface substantially parallel to a first plane and a second surface substantially parallel to a second plane perpendicular to the first plane, wherein the first surface has a first area and the second surface has a second area smaller than the first area;a plurality of conductive traces formed in a layer of the printed circuit board substantially parallel to the first plane; andone or more recess at the second surface, each of the one or more recess including an inner surface, a portion of the inner surface adapted to form a first electrical contact connected to one of the plurality of conductive traces; and a socket adapted to electrically interface with the printed circuit board, the socket including:
a plurality of conductive pins; andone or more mechanical support adapted to match the position of the one or more recess, each of the one or more mechanical support including an outer surface, a portion of the outer surface adapted to form a second electrical contact connected to an interface pin; wherein, the first electrical contact at the printed circuit board and the second electrical contact at the socket form a conduction path from one of the plurality of conductive traces on the printed circuit board to the interface pin at the socket when the printed circuit board is inserted into the socket. |
