Beschreibung
Zusammenfassung:	A tamper respondent enclosure including (a) a circuit board; (b) an enclosure surrounding the circuit board; (c) a tamper respondent sensor having (i) a substrate with first and second sides; (ii) a first layer of conductive traces on the first side; (d) wherein the tamper respondent sensor is wrapped around the enclosure with at least one overlap region; and (e) wherein only at the at least one overlap region the tamper respondent sensor has a second layer of conductive traces on the second side. Preferably, the substrate is insulating and made of opaque PET, and the first layer is adjacent the enclosure.
