With our free defined layer buildups and many layout examples for impedance (4, 6 and 8 layers) you can approximate your desired values for impedances. All example values given are average values based on our many years of experience and serve as a basic orientation. The actual values depend on the individual PCB layout and the chosen manufacturing technology.
