5G microwave Absorbing Thermal pad are composite materials that combine electromagnetic wave absorption and thermal conduction functions. They are primarily composed of polymer substrates, thermally conductive fillers, and wave-absorbing fillers (such as magnetic materials). These pads can effectively absorb electromagnetic waves in the 5G frequency bands (especially millimeter wave frequencies) while efficiently conducting heat generated by electronic components, thereby solving the dual challenges faced by 5G equipment operating at high frequencies.
