Abstract
A printed circuit board which has a layer of electrically resistive material that can provide a pull-up/pull-down resistor for the board. The printed circuit board includes a substrate which has a conductive plane located on the top surface of the board. The conductive plane is typically dedicated to electrical power. The board also has a via that is connected to an internal signal line. The resistive material is applied to the top surface to connect the conductive plane to the via and the signal line. The resistive material can be applied with a screening process which simplifies the assembly process of the resistor. Additionally, the resistive material is relatively small and located adjacent to the via so that the resistor does not occupy valuable board space.
