Abstract: An apparatus includes a substrate and first and second electrical connectors. The apparatus also includes at least one first conductive trace positioned in, on, or over the substrate. The at least one first conductive trace forms an electrical connection between the first and second electrical connectors. The at least one first conductive trace is configured to be damaged by laser energy to break the electrical connection between the first and second electrical connectors. The apparatus further includes an indicator electrically coupled to the at least one first conductive trace. The indicator is configured to generate feedback based on whether the electrical connection between the first and second electrical connectors has been broken.
