AI Technical Summary

Problems solved by technology

Such radiation may cause electromagnetic interference (EMI) or radio frequency interference (RFI) that can interfere with the operation of other electronic devices within a certain proximity
Without adequate shielding, EMI / RFI interference can cause degradation or complete loss of vital signals, rendering electronic equipment inefficient or inoperable

Embodiment Construction

[0024] Example embodiments will now be described more fully with reference to the accompanying drawings.

[0025] Exemplary embodiments of thermally conductive EMI absorbers comprising silicon carbide are disclosed herein. For example, an exemplary embodiment of a thermally conductive EMI absorber comprising silicon carbide, carbonyl iron powder, and alumina is disclosed. In some exemplary embodiments, the thermally conductive EMI absorber also includes manganese zinc (MnZn) ferrite and magnetic fragments.

[0026] As disclosed herein, the inventors have discovered that the combination of silicon carbide (SiC) with a thermally conductive material such as aluminum oxide (Al 2 o 3 ), ceramics, etc.) and EMI absorbing materials (e.g., carbonyl iron powder (CIP), magnetic fragments, manganese zinc (MnZn) ferrite, other EMI absorbing materials, etc.) work together to enhance thermal conductivity and EMI absorption (e.g. figure 1 , figure 2 as well as Figure 5 etc.). The res...

Abstract

According to various aspects, exemplary embodiments are disclosed of thermally-conductive EMI absorbers that generally include thermally-conductive particles, EMI absorbing particles, and silicon carbide. The silicon carbide is present in an amount sufficient to synergistically enhance thermal conductivity and / or EMI absorption. By way of example, an exemplary embodiment of a thermally-conductive EMI absorber may include silicon carbide, magnetic flakes, manganese zinc ferrite, alumina, and carbonyl iron.
