PCB Layer Sequence

If your design has too many connections or uses high speed signals, add 2 more inner signal layers. Start layout and try to fit everything into these 4 layers (top and bottom + 2 inner layers).

If you need a little bit more space, mix your power plane layer(s) with not important or slow signals; however, if you need a lot of space, add two more signal layers.

After the determination of PCB layer number, the sequence of PCB layers has many options. The following order is just for your reference:  

4-layer stackup: Important Signals/ GND/ Power/ Signals

6-layer stackup: Signals/ GND/ Power or Mixed with signals/ Power or Mixed with signals/ GND/ Signals

8-layer stackup: Signal/ GND/ Signal/ Power/ Power/ Signal/ GND/ Signal

10-layer stackup: Signal/ Solid GND/ High speed signals and important buses/ Solid Power or Solid GND/ Power or Mixed with signals/ Power or Mixed with signals/ Solid Power or Solid GND/ High speed signals and important buses/ Solid GND/ Signal

12-layer stackup – two additional signal layers: Signal/ Solid GND plane/ Signal/ Signal/ Solid Power Plane/ Power or Mixed with signals/ Power or Mixed with signals/ Solid Power Plane/ Signal/ Signal/ Solid GND plane/ Signal

12-layer stackup – 4 GNDs: Signal/ Solid GND plane/ High speed signals and important buses/ Solid GND plane/ Power/ Power or Mixed with signals/ Power or Mixed with signals/ Power/ Solid GND plane/ High speed signals and important buses/ Solid GND plane/ Signal
