Patent ID: 8007286

Claim:
An interconnectable circuit board array, comprising: a plurality of interconnectable circuit boards, each circuit board comprising a distal end having a first electrically conductive pad located on a top of the circuit board; a plated through hole located on the conductive pad, the through hole passes through a conductive layer of the circuit board, an insulative layer of the circuit board and a second separate conductive layer of the circuit board, the plated through hole allowing solder to flow from the conductive layer to the second conductive layer; a second electrically conductive pad coupled to the plated through hole, the second electrically conductive pad capable of coupling with an electrical component; and a proximal end having a third electrically conductive pad attached to the top of the circuit board; wherein each of the plurality of interconnectable circuit boards includes a portion that overlaps with another interconnectable circuit board to form an overlapping joint and a portion that does not overlap with another interconnectable circuit board.
