Designing the multilayer PCB

2017/5/18 11:53:08

1.When designing the multilayer printed circuit board, the power plane should be close to the ground plane and placed under the ground plane.
2.When designing multilayer PCBs, the wiring layer should be arranged adjacent to the entire metal plane.
3.In the design of multi-layer printed circuit board, the digital circuit and analog circuits should be separated and better to be arranged in different layers if necessary. If you want them in the same layer, you can use ditch, add ground lines, separation and other methods. Both the ground and power of analog and digital should be separated.
4.Different layout area should be assigned in the printed circuit board when the high-speed, medium and low-speed digital circuit are mixed.
5.Low-level analog circuits and digital logic circuits should be separated as much as possible.
