Abstract

The invention relates to an electric device, which comprises frame, first circuit board, second circuit board and conductors, wherein the frame has the first wall and conductive second wall, while they are opposite; the first circuit board is fixed on the first wall, while it is between the first and second walls; the second circuit board is in the frame, with at least one electric element on the second circuit board; the first side of second circuit board contacts the first circuit board; the conductor contacts at least part of second circuit board and contacts the second wall; the inventive elements have better electromagnetic compatibility.

Description

technical field [0001] The invention relates to an electronic device, and in particular to an electronic device with anti-electromagnetic interference. Background technique [0002] Among the evaluation standards of various electronic devices, Electromagnetic Compatibility (EMC) is a key quality index. The evaluation of electromagnetic compatibility includes electromagnetic interference (Electromagnetic Interference, EMI) and anti-electromagnetic interference (Electromagnetic Susceptibility, EMS). Because the signal transmission speed of the advanced electronic device is getting faster and faster, the electromagnetic interference caused by the electronic components inside the electronic device will become more and more serious, and then affect the normal operation of other electronic components in the electronic device. [0003] Electromagnetic interference has channels such as conduction and radiation, and radiated electromagnetic interference usually must be solved by cha...
