Abstract
Tamper-respondent assemblies and fabrication methods are provided which incorporate enclosure to circuit board protection. The tamper-respondent assemblies include a circuit board, and an electronic enclosure mounted to the circuit board and facilitating enclosing at least one electronic component within a secure volume. A tamper-respondent electronic circuit structure facilitates defining the secure volume, and the tamper-respondent electronic circuit structure includes a tamper-respondent circuit. An adhesive is provided to secure, in part, the electronic enclosure to the circuit board. The adhesive contacts, at least in part, the tamper-respondent circuit so that an attempted separation of the electronic enclosure from the circuit board causes the adhesive to break the tamper-respondent circuit, facilitating detection of the separation by a monitor circuit of the tamper-respondent electronic circuit structure.
