How much do you know about PCB circuit board?
Electromagnetic compatibility refers to the ability of electronic equipment to work harmoniously and effectively in various electromagnetic environments.The purpose is to make the electronic equipment can not only suppress all kinds of foreign interference, so that the electronic equipment can work normally in a specific electromagnetic environment, but also can reduce the electronic equipment itself to other electronic equipment electromagnetic interference.
1. Choose a Reasonable Wire Width The impact interference caused by transient current on PCB printed circuit board lines is mainly caused by the inductance of the printed wire, so the amount of inductance of the printed wire should be reduced as far as possible.
2, USES the correct wiring strategy USES the equal linear conductor inductance can be reduced, but the mutual inductance between conductor and distributed capacitance increases, the layout of permitting, had better use well glyph structure network cabling, specific side lateral approach is printed circuit board wiring, the other side vertical wiring, then at the cross hole is connected with metallized hole.
3. In order to suppress crosspoiling between conductors of PCB circuit board, it is necessary to avoid long-distance equal wiring in wiring design, to open the distance between wires as far as possible, and not to cross signal wires, ground wires and power lines as far as possible.Crosstalk can be effectively suppressed by placing a printed line between some signal lines which are very sensitive to interference.
