A printed circuit board. The novel printed circuit board includes a substrate, a layer of conductive material disposed on the substrate, and a solder mask layer disposed on the conductive layer, the solder mask layer including cutouts shaped as reference text and/or art. The conductive layer is etched to form traces for connecting electronic components to be mounted on the board in a desired pattern to form an electrical circuit and may include pads and lands to which the components are to be soldered. The solder mask layer is made from a material that resists wetting by solder and also includes cutouts in areas where the components are to be soldered to the conductive layer. The reference text and/or art includes readable information for assembling, testing, and/or repairing the circuit board, such as component part numbers, reference designators, pin one identifiers, component outlines, and test point identifiers.
