More Information
Summary:Tamper-respondent assemblies are provided which include an enclosure with an edge surface, and a tamper-respondent sensor. The tamper-respondent sensor covers, at least in part, the edge surface and an inner surface of the enclosure. The sensor includes at least one tamper-detect circuit. The tamper-detect circuit(s) includes a conductive trace(s) in a tamper-detect pattern. The tamper-respondent sensor includes exposed regions and unexposed regions of the conductive trace(s) at the edge surface of the enclosure to facilitate an adhesive directly contacting the at least one conductive trace in the exposed regions.
