So, to reach 80 the target ohms impedance, is it recommended to reduce screening to a minimum (thin traces that stay away from the signal lines as far as possible to get close to the "microstrip" configuration, as suggested by JLPCB to get 80 ohms), or is it recommended to ground pour the signal layers as much as possible to get to the. I'm working on open source software defined radio based on XC7Z020. Save. From what I read, to attempt to design to match an impedance value, you need to put a copper fill (GND) on the back of the PCB, have no interruptions to that ground plane under the traces, and set your data line traces to be a specific width, and a specific width apart - and - also try and keep the traces the same length. 3.
