Observe that, Because you positioned power on an internal layer, that doesn’t suggest you can’t set power in other places. You are able to however route power in your other signal layers as rails applying copper pour, or as thick traces. Look at embedded capacitance layers for high-frequency decoupling and https://6-layeruav-specificelectr50482.fare-blog.com/31355836/top-latest-five-four-layer-inner-and-outer-layers-2oz-copper-thick-pcb-circuit-board-urban-news
