    Abstract: Tamper-respondent assemblies are provided which include a circuit board, an enclosure assembly mounted to the circuit board, and a pressure sensor. The circuit board includes an electronic component, and the enclosure assembly is mounted to the circuit board to enclose the electronic component within a secure volume. The enclosure assembly includes a thermally conductive enclosure with a sealed inner compartment, and a porous heat transfer element within the sealed inner compartment. The porous heat transfer element is sized and located to facilitate conducting heat from the electronic component across the sealed inner compartment of the thermally conductive enclosure. The pressure sensor senses pressure within the sealed inner compartment of the thermally conductive enclosure to facilitate identifying a pressure change indicative of a tamper event.

  • Patent number: 11614324
    Abstract: Aspects of the invention include a non-destructive bond line thickness measurement of thermal interface material on silicon packages. A non-limiting example computer-implemented method includes receiving a chip mounted on a laminate and depositing a high-density material on the chip. The computer-implemented method deposits a thermal interface material on the chip and lids the chip, and the laminate with a lid. The computer-implemented method X-rays the lid, the chip, and the laminate to produce an X-ray and measures, using a processor, from the X-ray a bond line thickness of the TIM as a distance from a bottom of the lid to a top surface of the high-density material.

  • Patent number: 11191155
    Abstract: Tamper-respondent assemblies are provided which include a circuit board, an enclosure assembly mounted to the circuit board, and a pressure sensor. The circuit board includes an electronic component, and the enclosure assembly is coupled to the circuit board to enclose the electronic component within a secure volume. The enclosure assembly includes an enclosure with a sealed inner compartment, and a structural material within the sealed inner compartment of the enclosure. The structural material within the enclosure inhibits deflection of the enclosure due to a pressure differential between pressure of the sealed inner compartment and pressure around, at least in part, the enclosure. The pressure sensor senses pressure within the sealed inner compartment of the enclosure to facilitate identifying a pressure change indicative of a tamper event.

  • Patent number: 11158562
    Abstract: An integrated circuit (IC) device package includes an IC device connected to an upper surface of the IC device carrier. Due to operation conditions or IC device package makeup, the IC device may warp. The warped IC device may include a convex upper surface. A conformable lid is connected to the IC device and includes an internal chamber and a deformable floor. The deformable floor is able to deform or bend along with the IC device. After deformation, the deformable floor may include a concave lower surface. A uniform bond line thickness of a thermal interface material that connects the IC device and the conformable lid is able to be achieved due to the deformable floor deforming or bending along with the IC device.
