Multilayer printed circuit board having tamper detection circuitry

摘要

A multilayer printed circuit board is provided. The multilayer printed circuit board includes a first and a second substrate each having a conductive signal trace; and a third substrate positioned between the first and the second substrate. The third substrate includes at least one integrated circuit mounted thereon. Tamper detection circuitry is in electrical communication with at least one of the conductive traces and is configured for providing a security response after detection of an interruption in an electrical connection provided by the at least one conductive trace.
