PCB Knowledge:

If there are more layers of the circuit board and more types of special signal layers, layers and power layers are arranged and combined, it is more difficult to determine which combination is the best, but the general principles are as follows.

The signal layer should be adjacent to an internal electric layer (internal power layer), using the large copper film of the inner electric layer to shield the signal layer.

The inner power layer and ground layer should be tightly coupled; the thickness of the medium between the internal power layer and ground layer should be taken as a small value. The capacitance between the power layer and ground layer is increasing. It can increase the resonant frequency.

The high-speed signal transmission layer in the circuit should be the middle layer of the signal and between the two internal electrical layers. The copper film of the two inner electric layers can provide electromagnetic shielding for high speed signal transmission. It can effectively limit the radiation of the high speed signal between the two inner electric layers without interference.
