EMI control technology of PCB 2

2. Connector selection and signal terminal definition

The connector is a key link in high-speed signal transmission, and it is also a weak link that easily generates EMI. More ground pins can be arranged in the terminal design of the connector to reduce the distance between the signal and the ground, reduce the effective signal loop area that generates radiation in the connector, and provide a low-impedance return path. If necessary, consider isolating some key signals with ground pins.
