　　EMC refers to the ability of electronic equipment to work coordinately and effectively in various electromagnetic environments. The purpose is to make electronic equipment not only suppress various external interference, so that electronic equipment can work normally in a specific electromagnetic environment, but also reduce the electromagnetic interference of electronic equipment itself to other electronic equipment.

　　1. Select a reasonable wire width. Since the impact interference caused by transient current on the printed lines of PCB is mainly caused by the inductance of the printed wire, the inductance of the printed wire should be minimized.

　　2. The correct wiring strategy and equal routing can reduce the conductor inductance, but the mutual inductance and distributed capacitance between the conductors increase. If the layout allows, it is better to use the well shaped network wiring structure. The specific method is that one side of the printed board is wired horizontally and the other side is wired longitudinally, and then connected with the metallized hole at the cross hole.

　　3. In order to suppress the crosstalk between the wires of PCB circuit board, long distance equal routing shall be avoided as far as possible during the design of wiring, the distance between lines shall be pulled as far as possible, and the signal line shall not cross the ground wire and power line as far as possible. A grounded printed wire is set between some signal wires that are very sensitive to interference, which can effectively suppress crosstalk.
