Abstract

An electronic device including a circuit board, a heat generating component and an electromagnetic wave shielding module is provided. The circuit board has a ground plane. The heat generating component is disposed on the circuit board. The electromagnetic wave shielding module includes a plurality of conductive components and a heat dissipating component. The conductive components are disposed on the circuit and electrically connected to the ground plane, wherein the conductive components are arranged with intervals and surround the heat generating component. The heat dissipation component is disposed on the heat generating component and connected to the conductive components, wherein the heat dissipating component covers and contacts with the heat generating component to dissipate heat from the heat generating component and shield an electromagnetic wave generated by the heat generating component, and the electromagnetic wave is transmitted to the ground plane and drained through the conductive components.

Description

technical field [0001] The invention relates to an electronic device and its electromagnetic wave shielding module, and in particular to an electronic device and its electromagnetic wave shielding module with heat dissipation function. Background technique [0002] In recent years, the operating speed of electronic devices such as smart phones, tablet PCs, and notebook computers has been continuously improved, and the heating power of electronic components in the electronic devices has also been continuously increased. . In order to prevent the temporary or permanent failure of the electronic components due to overheating, it is necessary to install cooling fins and other heat sinks on the electronic components to reduce the temperature of the electronic components.

Problems solved by technology

However, the current electronic devices are designed towards the trend of thinner and lighter, and the internal configuration space is also reduced. For example, the area of ​​the motherboard of small-sized electronic devices (such as tablet computers) becomes smaller, so all electronic components are close to each other. Nearby, the noise is getting bigger and harder to suppress, and the motherboard often uses through holes instead of blind holes for wiring, so that the wiring cannot go through the inner layer but the surface layer, so it will also cause no traces on the surface of the motherboard. Sufficient space can be used to install electromagnetic wave shielding structures, so how to properly arrange heat sinks and electromagnetic wave shielding structures in the limited configuration space of electronic devices is an important issue in the design of current electronic devices
