Abstract
Various aspects of the present disclosure provide tamper-evident seals and methods for indicating tampering with an apparatus using the tamper-evident seals. One such tamper-evident seal includes a base layer and a pattern-release layer on a periphery area of the base layer. In such case, the pattern-release layer includes a first adhesive configured to leave a residue on the printed circuit board assembly, and the base layer has a central area that is surrounded by the periphery area and free of the first adhesive.
