Impedance Control Files

If your PCB requires impedance controlled traces then additional files are needed to correctly manufacture your PCBs. The information required are which traces are impedance controlled and the specifications of said traces. Which traces are impedance controlled can be shown in an assembly document, provided as a separate gerber file, or as an image with the traces marked. The specifications of the traces that are necessary is the resistance of the traces, trace width, and trace space.

For example:

Traces to be controlled: Gerber File

Traces are to be 75 ohms ±15%.

Traces are 10mil and 10mil spacing

Layer is Top Copper
