Hi guys: If I wanted a PCB with two different values of controlled impedance, say some 50 ohm traces and some 40 ohm traces, is this relatively easy to design and fabricate, or would I end up paying a lot more for both the design of the board and production quantities? Also, is this fairly common, a board with multiple values of controlled impedance traces? Appreciate any insight.
