Particular embodiments described herein provide for an electronic device can include a support structure, a radiation source on the support structure, and a radiation shield around the radiation source. The radiation shield includes a wall secured to the support structure, a vacuum bag on the wall, where the vacuum bag has an inside air pressure less than an air pressure outside the vacuum bag, and a lid. The air pressure inside the vacuum bag is less than the atmospheric pressure outside the vacuum bag. When the vacuum is created in the vacuum bag, the vacuum bag deforms and compresses to help provide a vacuum-based mechanical loading that helps to create an applied load on the one or more radiation sources by the lid.

The module includes a Printed Circuit Board (“PCB”); one or more circuits mounted to the PCB; and a faceplate that including a plurality of plates, angled relative to one another, such that the faceplate includes increased surface area relative to a substantially flat faceplate, wherein at least two plates of the plurality of plates include physical ports each having track lengths to a circuit of one or more circuits, wherein one or more of the physical ports support signals at a rate of at least 100 Gbps. Each plate of the plurality of plates can be flat. Any of the plurality of plates can include physical ports. The physical ports can be pluggable modules. Each type of the physical ports can be a same type on a given plate.

Low-profile fasteners with springs that are either integrated with the fastener or are a physically separate component can provide a more evenly distributed load to a heat transfer device, such as a vapor chamber or a heat pipe. The low-profile fasteners do not increase the height of the base of a mobile computing device as the spring and the portion of the fastener that extends past the spring fit within a recess or cavity of the heat transfer device. The spring can be a diaphragm spring, a wave spring, or another suitable spring. The use of low-profile fasteners with springs to fasten a heat transfer device to a mainboard may allow for designs with a smaller mainboard area, which can leave room for a larger thermal management solution (which can increase cooling capacity) and allow for a greater thermal design power for the system.

A high-resolution substrate having an area of at least 100 square centimeters and selected traces having a line/space dimension of 2 micrometers or less is employed to integrate multiple independently operable clusters of flip chip mounted components, thereby creating a circuit assembly. Each independently operable cluster of components preferably includes a power distribution chip, a test/monitor chip, and at least one redundant chip for each type of logic device and for each type of memory device. The components in at least one of the independently operable clusters of components may include the components provided in a commercially available chiplet assembly. An electronic system may comprise multiple substrates comprising independently operable clusters of components, plus a motherboard, a system controller, and a system input/output connector.
