Abstract

The embodiment of the present application relates to the technical field of circuit boards, and discloses a circuit board assembly and electronic equipment. In this application, a microstrip structure is set at the HDMI trace on the circuit board, that is, the HDMI trace connected to the HDMI interface, to couple the harmonics at the HDMI trace on the circuit board and limit them in the shielding cover and gradually consumption, thereby eliminating the influence of harmonics on WiFi signals when they are transmitted to the back end, and improving the stability of WiFi connections. At the same time, because this application adopts the method of setting the microstrip structure on the surface of the circuit board, it avoids The filter used to filter out harmonics is directly connected to the transmission path of the HDMI signal and affects the transmission power of the HDMI signal, which greatly reduces the impact on the power of the HDMI signal and also reduces the entire circuit. The volume of the plate.

Description

technical field [0001] The embodiments of the present application relate to the technical field of circuit boards, and in particular to a circuit board assembly and electronic equipment. Background technique [0002] At present, in the field of consumer electronics, wireless fidelity (WIreless-Fidelity, WIFI) and high-definition multimedia interface (High Definition Multimedia Interface, HDMI) have almost become indispensable requirements. The data is transmitted to the TV through the HDMI interface; however, the HDMI signal transmitted by the HDMI interface carries harmonics that can interfere with the WiFi2.4GHz signal, and the harmonics will interfere with the WiFi signal in the WiFi channel, making it difficult for the user to receive the WiFi signal. The effect is poor. In the related art, in order to solve the interference problem of the HDMI signal to the WiFi signal, a method is adopted: adding a filter circuit to the HDMI channel to filter out the harmonics in the ...
