Abstract
The present invention relates to a method to fabricate a tamper respondent assembly. The tamper respondent assembly includes an electronic component and an enclosure fully enclosing the electronic component. The method includes printing, by a 3-dimensional printer, a printed circuit board that forms a bottom part of the enclosure and includes a first set of embedded detection lines for detecting tampering events and signal lines for transferring signals between the electronic component and an external device. The electronic component is assembled on the printed circuit board, and a cover part of the enclosure is printed on the printed circuit board. The cover part includes a second set of embedded detection lines. Sensing circuitry can be provided for sensing the conductance of the first set of embedded detection lines and the second set of embedded detection lines to detect tampering events.
