 In theory, there can be three options.


Solution one, a power layer, a ground layer and two signal layers, are arranged in this way: TOP (signal layer), L2 (earth layer), L3 (power layer), BOT (signal layer).

Scheme 2, a power layer, a ground layer and two signal layers, respectively, are arranged: TOP (power layer), L2 (signal layer), L3 (signal layer), BOT (stratum).

Scheme 3, 1 power layer, 1 ground layer and 2 signal layers, respectively, are arranged in this way: TOP (signal layer), L2 (power layer), L3 (ground layer), BOT (signal layer).
