Avoiding high-frequency radiation PCB assembly china design

In order to avoid electromagnetic radiation generated when high-frequency signals pass through printed wires, the following points should also be noted when wiring PCB assembly china:

1. PCBA assembly Reduce the discontinuity of printed wires, such as avoiding sudden changes in wire width, ensuring that wire corners are greater than 90 degrees, and prohibiting circular routing.

2. Clock signal leads are most prone to electromagnetic radiation interference. When routing, they should be close to the ground circuit, and the driver should be placed next to the connector.

3. The bus driver should be located next to the bus it intends to drive. For those leads that leave the printed circuit board, the driver should be tightly attached to the connector.

4. The wiring of the pcba assembly data bus should have a signal ground wire sandwiched between every two signal lines. It is best to place the ground circuit closely next to the least important address lead, as the latter often carries high-frequency currents.
