Measuring the Dielectric Coefficient of PCB Material (033)

If you are planning a project that requires controlled impedance traces on a PC board, then you need to know certain things about the PC board material you are using.
In this video I will be showing you how to gather some of this information like:
  * dielectric coefficient of the substrate
  * thickness of the substrate
  * thickness of the copper
It is not a hard process. It isn't even highly technical.  The average experimenter can do this with an inexpensive VNA like the nanoVNA or miniVNA tiny.
