What is multi layer PCB?

Multi layer PCB is a printed circuit board with more than 2 layers, a multi layer PCBB must have at least 3 conductive layers of conductive material or copper layer. All layers of the multi layer PCB are interconnected with copper-plated holes. Multi layer PCB can be 4 layers, 6 layers, 8 layers, or even 20 layers.

Multi layer PCB layout rules

The power layer plane of the multi layer PCB should be close to the ground plane and designed under the ground plane. The wiring layer of the multi layer PCB should be adjacent to the entire metal plane. The digital signal and analog signal of the multi layer PCB should have an isolation design. The layer PCB should avoid digital signals and analog signals on the same layer. The electromagnetic compatibility of the multi layer PCB can be greatly improved through the design of the number of layers and the layout of the layers.
