Electromagnetic Interference Suppression Design of PCB

2024/01/05

The design of printed circuit board is an important part of making electronic products. With the rapid development of electronic technology, the density of PCB is getting higher and higher, and the quality of PCB design in circuit board factory has a great influence on anti-interference ability. If the design is unreasonable, it will produce electromagnetic interference, which will affect the performance of the circuit and even fail to work normally.

1. electromagnetic interference is mainly

1. There are inductance effect, resistance effect, conductivity effect and mutual inductance effect between parallel wires. A changing current on one wire necessarily affects the other wire, causing interference.

2. Printed wires on the printed board, connecting wires outside the board and even component leads may become antennas for transmitting or receiving interference signals. This is especially not negligible in the PCB design of high-frequency circuits in circuit board factories.

3. The magnetic components in the circuit, such as the constant magnetic field generated by the speaker, electromagnet, permanent magnet meter, etc., and the sudden magnetic field generated by the transformer, relay, etc., will also have an impact on the printed board.
