Abstract:
Disclosed are exemplary embodiments of thermal management and/or electromagnetic interference (EMI) mitigation materials including coated fillers (e.g., coated thermally-conductive, electrically-conductive, dielectric absorbing, and/or electromagnetic wave absorbing particles, sand particles coated with a binder, other coated functional fillers, combinations thereof, etc.). For example, a thermal management and/or EMI mitigation material may comprise a thermal interface material (TIM) including one or more coated fillers (e.g., coated thermally-conductive particles, sand particles coated with a binder, etc.), whereby the TIM is suitable for providing a thermal management solution for one or more batteries and/or battery packs (e.g., a battery pack for electric vehicle, etc.), or other device(s), etc.
Abstract:
A system for applying thermal interface materials to components includes a supply of thermal interface material and a die. The die is operable for pushing against and/or removing a portion of the thermal interface material that is between the die and a corresponding one of the components. The portion of the thermal interface material is removed from the supply and applied to the corresponding one of the components.
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:
In an exemplary embodiment, a device generally includes a housing, an external heat sink, and at least one of a thermal interface material and a thermoelectric module generally between a side of the housing and the external heat sink. At least one spring contact may be coupled to the side of the housing generally between the connector and the at least one of a thermal interface material and a thermoelectric module. The at least one spring contact and the at least one of a thermal interface material and a thermoelectric module may define at least a portion of a thermally-conductive heat path between the housing and the external heat sink. Graphite may be wrapped around the at least one spring contact and/or a thermally-conductive and electrically-conductive material may be wrapped around at least a portion of the thermal interface material.
Abstract:
According to various aspects, exemplary embodiments are provided of thermal interface material assemblies. In one exemplary embodiment, a thermal interface material assembly generally includes a thermal interface material having a first side and a second side and a dry material having a thickness of about 0.0001 inches or less. The dry material is disposed along at least a portion of the first side of the thermal interface material.
Abstract:
According to various aspects, exemplary embodiments are disclosed of mid-plates and EMI shields for electronic devices. In an exemplary embodiment, a mid-plate generally includes one or more recessed portions along a surface of the mid-plate. A heat spreader is within the one or more recessed portions. Dielectric is along an outward-facing surface of the heat spreader. The dielectric inhibits the heat spreader from directly contacting and electrically shorting one or more components. In another exemplary embodiment, a board level shield (BLS) generally includes a cover having one or more recessed portions along an inner surface of the cover. A heat spreader is within the one or more recessed portions. Dielectric is along an outward-facing surface of the heat spreader, whereby the dielectric inhibits the heat spreader from directly contacting and electrically shorting one or more components when the one or more components are under the BLS.
Abstract:
A thermal interface material assembly generally includes a substrate and one or more pillars protruding outwardly away from the substrate. A thermally-conductive heat path is at least partially defined by the substrate and the one or more thermally-conductive pillars, whereby heat may be transferable along the thermally-conductive heat path from a heat source of an electronic device.
