For an internship project I need to make a polarity tester for a rotor with permanent magnets on it. I will be testing the polarity with Hall-sensors around the magnet.
Now i want to make a ring shaped PCB where I can solder the Hall-sensors onto. Does anyone know how to do this since I'm totally new to the PCB design environment.
On the internet I found a similar PCB design how it should look like. Here is the link:
You need to delete the rectangular board shape from the dimension layer and draw two circles on this layer which are the inner and outer diameter of your ring. EAGLE will then determine the outer circle is the board outline and the inner circle is a cut out.
