Abstract
A pre-drilled hole, providing a passageway between an upper and a lower surface of a printed circuit board layer, receives a passive component, for example a resistor or a capacitor. In one embodiment the component is cylindrical, with an electrically conductive contact point at each end. The hole diameter is approximately the same as the diameter of the cylindrical component. The hole is similar to a via in a printed circuit board, except that the hole is not plated through (such would cause an electrical short). Electrically conductive lines are provided to the openings of the hole on the upper and the lower surfaces of the PCB. The area of the exposed end of the cylindrical component and the termination of the conducting line is less than the area of a surface mounted component equivalent to the cylindrical component. In some embodiments the hole and inserted component are located directly below a pin pad for a surface mounted device, for example an integrated circuit, providing the equivalent of zero wire and line lengths with no net increase in printed circuit board area.
