Abstract: Tamper-detect assemblies and methods of fabrication are provided. A tamper-detect assembly includes a laminate carrier with embedded tamper-detect circuitry within the laminate carrier, and one or more electronic components on the laminate carrier. Further, the tamper-detect assembly includes a heat sink cover. The heat sink cover includes a heat sink and tamper-detect circuitry integrated within the heat sink cover. The heat sink cover is mounted to the laminate carrier and encloses the one or more electronic components between the laminate carrier and the heat sink cover. Together, the embedded tamper-detect circuitry of the laminate carrier and the integrated tamper-detect circuitry of the heat sink cover define, at least in part, a secure volume about the one or more electronic components.
