Checklist
Here's a checklist to make sure you did everything correctly:
- Did you perform all three checks in the Layout manager?
- Did you make sure your schematic is 100% correct?
- Have you printed a layout of your board at 100% scale to see if all your components align with pads on your printout?
- Did you make sure the traces are 20 mil wide?
- Did you have your teacher check your work?
- Did you make sure none of the traces touch the mounting holes?
