Abstract: The techniques disclosed herein enable improved security as well as more scalable and reliable job execution by utilizing granular security boundaries and certificate-based authentication for all communication within cloud-based platforms. To manage a cloud-based platform, a system receives a plurality of jobs and associated certificates at a first security boundary that are to be executed at various resource units within a second security boundary. The system then authenticates each certificate before transmitting each job to its respective resource unit for execution. In addition, the system is further configured to monitor active certificates for compromise and accordingly isolate various security boundaries in the event of a security breach. By isolating portions of the cloud-based platform within security boundaries, the system can mitigate the impact of security breaches. Furthermore, certificate-based authentication addresses performance constraints to enable more efficient and scalable job execution.

Abstract: Aspects of the invention include receiving a printed circuit board (PCB) having one or more of mounting pads thereon, determining a stencil for applying a solder paste to the one or more mounting pads, the stencil having a smallest aperture for a component requiring a standoff, determining a maximum threshold size for standoff particles based on the smallest aperture, determining a first concentration of the standoff particles based on the smallest aperture, determining a minimum threshold size for standoff particles to create the standoff for the component, determining a second concentration of the standoff particles to create a three-standoff seating plane for the component, introducing the standoff particles to the solder paste, the standoff particles in the solder paste having a concentration between the first concentration and the second concentration, and a size between the maximum threshold size and the minimum threshold size.

Abstract: A tamper resistant enclosure for an electronic circuit includes an inner copper case, a tamper sensing mesh wrapped around the inner case, an outer copper case enclosing the inner case and the tamper sensing mesh, and a venting device forming a vent channel from inside the inner case to outside the outer case, the vent channel passing between overlapping layers of the tamper sensing mesh and having at least one right angle bend along its length. The venting device consists of two strips of a thin polyamide coverlay material laminated together along their length, and a length of wool yarn sandwiched between the two thin strips and extending from one end of the strips to the other end of the strips to form the vent channel. The length of yarn follows a zig-zag path between the first and second strips, the zig-zag path including at least one right angle bend.

Abstract: A circuit card having module strain relief and heat sink support is provided. The circuit card comprises a printed circuit board having a front and a back, a module mounted to the front of the printed circuit board, and a stiffening structure mounted to the back of the printed circuit card directly opposite from the module to provide rigidity to the printed circuit board. The module has a plurality of electrical leads making electrical connection with the printed circuit board and anchoring the module to the printed circuit board. The stiffening structure is coextensive with the plurality of electrical leads along the printed circuit board, and is of sufficient thickness and strength to resist flexure of an area of the printed circuit board in contact with the stiffening structure in response to shock and vibration applied to the module.
