Circuit Board Design Compatible

Electromagnetic compatibility refers to the electronic device is still able to coordinate the various electromagnetic environments, the ability to work effectively. The purpose is not only to suppress the electronic equipment

Circuit board

 Made all kinds of outside interference, the electronic device can work in a specific electromagnetic environment, while reducing the electronic device itself electromagnetic interference with other electronic devices.

1, a reasonable choice of wire width due to the transient current in PCB printed circuit board on the lines of the impact of interference generated mainly by the printed wire inductance component caused by printed conductors and therefore should minimize inductance.

2, using the correct cabling strategy adopted equality traces can reduce lead inductance, mutual inductance and distributed capacitance increases but between the wires, if layout allows the best use of well-shaped mesh wiring structure, which would be the lateral side of the printed circuit board wiring, the other side of the longitudinal wires, and then connected by metallized holes in the cross hole.

3, in order to suppress crosstalk between the wires of the PCB, the wiring should be designed to avoid long-distance equal traces distance as possible between the lines, the signal line and the power line and the ground as possible without cross. Some are susceptible to interference between the signal line traces a grounded, can effectively suppress crosstalk.
