A device that comprises an outer component, an inner component and a filter module. The outer component includes a first hollow cylinder, and exterior ports in sidewalls of the first hollow cylinder. The inner component is positioned coaxially within the first hollow cylinder, and includes a second cylinder, and interior ports in the second cylinder, wherein the interior fluid ports are aligned parallel to the exterior ports. The filter module includes a hollow prism positioned coaxially within the outer component and surrounding the inner component, the hollow prism comprising at least four faces configured to retain filters. The filter module also includes vanes positioned along edges connecting the at least four faces and forming seals with the first hollow cylinder. A first filter is provided on a first face, of the at least four faces, which is aligned between a pair of the interior and exterior ports.

Filter device having multiple changeable filter surfaces

Apparatuses and methods of fabrication are provided which include a coolant-cooled heat sink through which coolant passes to facilitate cooling the coolant-cooled heat sink, and an ultra-violet (UV) light assembly associated with the coolant-cooled heat sink for directing UV light towards an interior surface of the coolant-cooled heat sink across which the coolant passes. The UV light inhibits bacterial growth at the interior surface of the coolant-cooled heat sink.

A method of preparing a computer processor die includes determining a warpage shape of the computer processor die at a testing temperature. The method also includes selectively contouring a thickness of the computer processor die at a contouring temperature by physically removing material from a surface of the computer processor die such that the surface will be substantially flat at the testing temperature.

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.

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.

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.

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.
