Problems solved by technology

[0005] In addition, a common problem with the operation of electronic equipment is the generation of electromagnetic radiation within the electronic circuits of the equipment
This radiation may cause electromagnetic interference (EMI) or radio frequency interference (RFI), which may interfere with the operation of other electronic equipment within a distance
Without adequate shielding, EMI / RFI interference can cause attenuation or complete loss of important signals, rendering electronic equipment inefficient or inoperable

Embodiment Construction

[0025] Example embodiments will be described in detail below with reference to the accompanying drawings.

[0026] Board-level shields effectively block radiated electromagnetic emissions. But board-level shields are not effective thermal interface materials, so thermal issues are a concern. To alleviate thermal issues, holes can be made in the BLS to allow heat to escape. Thermal interface materials (TIMs) can also be used to direct heat to the outside of the BLS. But as the inventors of the present invention realized, the aperture and TIM create an effective channel for electromagnetic interference (EMI) to escape from underneath the BLS.

[0027] Inserting the TIM into the BLS opening increases radiated electromagnetic emissions due to the TIM acting as a channel or waveguide that directs energy to the outside through the BLS opening. Replacing the TIM material with a thermally conductive microwave absorber material did not solve the problem. In the past, thermally cond...

Abstract

The invention relates to thermal interface materials including an electrically-conductive material. According to various aspects, exemplary embodiments are disclosed of thermal interface materials including an electrically-conductive material, shields including thermal interface materials, and related methods.

Description

technical field [0001] The present disclosure generally relates to thermal interface materials that include electrically conductive materials. Background technique [0002] This section provides background information related to the present disclosure which is not necessarily prior art. [0003] Electronic components (such as semiconductors, integrated circuit components, transistors, etc.) typically have a pre-designed temperature at which they operate optimally. Ideally, the pre-designed temperature is close to the temperature of the surrounding air. However, the operation of electronic components generates heat. If the heat is not removed, electronic components may operate at temperatures significantly higher than their normal or expected operating temperature. Such excessive temperatures can adversely affect the operating characteristics of electronic components and the operation of associated equipment. [0004] In order to avoid or at least reduce the adverse opera...
