Each controlled impedance layer will need 1 or 2 reference planes. If you’re certain you want 8 signal layers, then you want a 14-16 layer stack up. You’re probably at the crossover point where going HDI with blind/buried laser vias, and less layers, is ...
WebNov 14, 2024 · PCB Stackup Guidelines for High-Speed Circuits. Many years ago, you could design many printed circuit boards without much thought to signal integrity because the signal speeds of the boards weren’t fast enough to warrant any concern. That is no longer the case, however, as even an average PCB design now needs signal integrity consideration.
