1) increase the intensity of the radiation electromagnetic field, as well as the spacing or shielding between components with more active electromagnetic induction.
2) try to avoid thick and cloudy bump voltage equipment, strong and weak signal equipment interwoven together.
3) during planning, the cut of the magnetic field line to the printed wire shall be cut, and the magnetic field directions of adjacent components shall be straight to each other to reduce mutual coupling.
4) the disturbing source shall be shielded and the shielding cover shall be well grounded.
