Method for eliminating electromagnetic interference by impedance match of electronic wire

Abstract

The present invention is a method for solving electromagnetic interference by using the impedance matching of electronic wires. In this method, the electronic wires are processed by the following methods: using laser or ultrasonic waves for hot melting, hot melting or gluing, and connecting data lines with data lines. ; or the data wire and the ground wire are kept equidistant, and the braided mesh or metal foil covered by the data wire directly connects it to the circuit board of the electronic product, or it is used as a ground wire, so that the inside of the wire will not be damaged during data transmission. Due to the impedance mismatch, the radiation phenomenon of the mismatched signal energy leaks to the outside of the wire, thereby forming electromagnetic interference. The several methods listed in the present invention are to solve the phenomenon of electromagnetic waves leaking from the wire, so that electronic products It can meet the range of electromagnetic standards when tested.

Description

technical field [0001] The invention relates to a method for solving electromagnetic interference by using impedance matching of electronic wires, especially a method for transmitting signal energy caused by signal reflection of wires used in electronic products (such as: USB interface, IEEE 1394) when transmitting data Leaking out of the wire leads to the problem of electromagnetic interference, and the present invention is just a variety of methods proposed to solve this problem. Background technique [0002] So far, the computer and electronics industry has become the main industry of our country. As far as the current situation is concerned, the manufacturing technology of my country's electronics industry has reached a world-class level, making my country the largest exporter of computers and electronic products, and also laying a foundation for my country's computer industry. And the technical foundation of the electronics industry. After the tec...
