What is EMC of circuit board design?

    东莞电路板设计电磁兼容性是什么？电磁兼容性是指电子设备在各种电磁环境中仍能够协调、有效地进行工作的能力。目的是使电子设备既能抑制各种外来的干扰，使电子设备在特定的电磁环境中能够正常工作，同时又能减少电子设备本身对其它电子设备的电磁干扰。

1. Select a reasonable wire width. The impact interference caused by transient current on the printed line of PCB circuit board is mainly caused by the inductance of the printed wire. Therefore, the inductance of the printed wire should be reduced as much as possible.

2. Using the correct wiring strategy and equal routing can reduce the conductor inductance, but the mutual inductance and distributed capacitance between conductors increase. If the layout allows, the well shaped mesh wiring structure is adopted. The specific method is to route horizontally on one side of the printed board and longitudinally on the other side, and then connect with metallized holes at the cross holes.

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