  • Patent number: 10965333
    Abstract: Exemplary embodiments are disclosed of thermal management assemblies suitable for use (e.g., configured for heat spreading, etc.) with transceivers (e.g., small form-factor pluggable (SFP) transceivers, SFP+ transceivers, quad small form-factor pluggable (QSFP) transceivers QSFP+ transceivers, XFP transceivers, etc.) and other devices (e.g., memory card readers, etc.). In exemplary embodiments, a thermal management assembly comprises at least one flexible heat spreading material (e.g., a single graphite sheet, multiple graphite sheets, etc.) including portions wrapped (e.g., in different non-parallel directions, in parallel directions, etc.) around corresponding portions of a part, which may be configured to be coupled to and/or along a side of a device housing. The at least one flexible heat spreading material may be operable for defining at least a portion of a thermally-conductive heat path around the corresponding portions of the part.

  • Publication number: 20070217877
    Abstract: method for forming an aperture includes stamping an aperture into the article using a pellet, and refining aperture shape(s) and/or aperture dimensions. Methods for forming articles having reduced residual compressive stress are also disclosed. Very generally, the methods include establishing a diamond coating on at least a portion of a substrate, and applying a stress-relief process to the diamond coating, the substrate, or combinations thereof.

  • Publication number: 20060147631
    Abstract: Disclosed is a method of making a coated substrate, especially a diamond coated substrate. In one embodiment, the method includes depositing an interlayer on a substrate to create an interlayer surface, peening the interlayer surface with a peening compound to create a peened interlayer surface, and depositing a coating on the peened interlayer surface to create a coated substrate wherein the peening compound comprises particles of the coating. Also provided is a method of drilling a nonferrous substrate such as aluminum with no more than minimum lubricants. The method includes providing a diamond coated drill produced by the foregoing method, and moving the drill against a nonferrous substrate under sufficient force such that the drill cuts and removes a portion of the substrate, wherein the moving of the drill against the substrate occurs under minimum lubrication conditions.
