Sensing and Energy Harvesting Devices
Security is a primary concern in producing laminate electronic devices, PCBs, and processing unit blades. These devices need to be able to thwart attempts by third parties attempting to gain access to their physical layout and electronic workings. These security measures protect valuable intellectual property (IP) and/or information being processed on the device.
In the past, common security measures target visual, X-ray, physical intrusion (i.e., drilling into the device), and electronic "sniffing" intrusion attempts. For visual security, a conformal coating/potting is used to cover the device which blocks visual identification of physical aspects on the board. For X-ray security, a metalized cover or coating can be used which either effectively blocks or absorbs X-ray energy. This prevents any identification of components or physical structures on the device being secured. For drilling security, a foil or mesh structure is used (see the figure below) to electrically detect intrusion through a cover surrounding the device being secured. This method requires a power source, either coming from main system power or preferably an on-board backup battery.
