Abstract:
Methods of fabricating tamper-respondent assemblies with bond protection are provided which include at least one tamper-respondent sensor having unexposed circuit lines forming, at least in part, one or more tamper-detect network(s), and the tamper-respondent sensor having at least one external bond region. The tamper-respondent assembly further includes at least one conductive trace and an adhesive. The conductive trace(s) forms, at least in part, the one or more tamper-detect network(s), and is exposed, at least in part, on the tamper-respondent sensor(s) within the external bond region(s). The adhesive contacts the conductive trace(s) within the external bond region(s) of the tamper-respondent sensor(s), and the adhesive, in part, facilitates securing the at least one tamper-respondent sensor within the tamper-respondent assembly. In enhanced embodiments, the conductive trace(s) is a chemically compromisable conductor susceptible to damage during a chemical attack on the adhesive within the external bond region(s).
