An electronic device includes a substrate, and the substrate may include one or more layers. The one or more layers may include a dielectric material and may include one or more electrical traces. The electronic device may include a layer of conductive material, and the layer of conductive material may define a void in the conductive material. The electronic device may include a fiducial mark, and the fiducial mark may include a filler material positioned in the void defined by the conductive material. The fiducial mark may be coupled to the layer of conductive material. The filler material may have a lower reflectivity in comparison to the conductive material, for instance to provide a contrast with the conductive material.
