Information

Electromagnetic compatibility refers to the ability of electronic equipment to work in a coordinated and effective manner in various electromagnetic environments. The purpose is to enable electronic equipment to suppress all kinds of external interference, so that the electronic equipment can work normally in a specific electromagnetic environment, and at the same time to reduce the electromagnetic interference of the electronic equipment itself to other electronic equipment. Let's follow the small home pcba editor to take a look at the compatible design knowledge of board circuit from China manufacturer!
1. Choose a reasonable wire width. The impact interference caused by the transient current on the printed lines of the PCB board circuit from China manufacturer is mainly caused by the inductance of the printed wires, so the inductance of the printed wires should be minimized. 


2. Using the correct wiring strategy and equal wiring can reduce the wire inductance, but the mutual inductance and distributed capacitance between the wires increase. If the layout permits, it is recommended to use a grid-shaped wiring structure, which is a horizontal wiring on one side of the printed board. , The other side is wired longitudinally, and then connected with metallized holes at the cross holes.
3. In order to suppress the crosstalk between the wires of the PCB board circuit from China manufacturer, try to avoid long-distance equal wiring when designing the wiring, and extend the distance between the wires as much as possible, the signal wire and the ground wire and the power wire Try not to cross as much as possible. Setting a grounded printed line between some signal lines that are very sensitive to interference can effectively suppress crosstalk.
The above is the small home pcba editor's description: about the compatible design knowledge of board circuit from China manufacturer.
