I am creating my first assembly drawing and have noticed that my ECAD tool generates a footprint with a top/bottom overlay and courtyard top/bottom.
Top Overlay is the silkscreen, but what is the courtyard top used for? (I tried looking it up but I did not find a good answer).
Is the courtyard top necessary or can I delete it and keep it simple with Top/bottom Overlay and Top/Bottom Assembly Drawing layer setup.
I mainly want to create a footprint format that is professional and follows good industry standards.
This is what I have right now.
No courtyard top/bottom with Top Overlay and Assembly Top line thickness of 0.2mm. The dark blue below pads is a 3D Top generated by ECAD tool.
