Abstract: Disclosed are systems for applying materials to components. The system comprises a tool operable for transferring a portion of a material from a supply of the material to a component. A first portion of the tool may be configured for cutting along a side or edge of the portion of the material. A second portion of the tool may be configured for tamping, pressing, or pushing against the portion of the material to cause uncut sides or edges of the portion of the material attached to the supply of the material to be torn, severed, detached, or separated from the supply of the material.
Abstract: According to various aspects, exemplary embodiments are disclosed of frames for shielding assemblies including detachable or severable pickup members. Also disclosed are exemplary embodiments of shielding assemblies (e.g., board level shields, etc.) including the same.
Abstract: Exemplary embodiments are disclosed of EMI shields including electrically-conductive foam (broadly, electrically-conductive resiliently compressible porous material). An exemplary embodiment includes an electromagnetic interference (EMI) shield for an optical transceiver including transmitter and receiver optical sub-assemblies. The EMI shield includes a portion having openings configured for receiving the transmitter and receiver optical sub-assemblies therethrough to thereby allow the EMI shield to be fit over the transmitter and receiver optical sub-assemblies for installation along a portion of the optical transceiver. The EMI shield also includes sidewalls depending from the portion that includes the openings. Electrically-conductive resiliently compressible porous material (e.g., electrically-conductive foam, etc.) is along at least a portion of an outer perimeter defined by the sidewalls.
Abstract: A device for absorbing energy from an electronic component includes a low melting alloy layer including a first side and a second side opposing the first side, and coating layers substantially covering the first side and the second side of the low melting alloy layer. In some embodiments, the low melting alloy layer includes a polymer mixture and a plurality of low melting alloy particulates dispersed in the polymer mixture. Other example devices are also disclosed.
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.

Abstract: In exemplary embodiments, a circuit assembly may be provided on and/or supported by an electrically conductive structure, such as a board level shield, a midplate, a bracket, a precision metal part, etc. For example, a circuit assembly may be provided on and/or supported by an outer top surface of a board level shield. In an exemplary embodiment, an assembly generally includes an electrically conductive structure configured for a first functionality in the electronic device. An electrically nonconductive material is on at least part of the electrically conductive structure. First electrical component(s) are at least partly on the electrically nonconductive layer and configured to define at least a portion of a circuit assembly for electrical connection with one or more second electrical components of the electronic device. The electrically conductive structure may thus be configured for a second functionality in the electronic device.
