Hello all,
Here goes my first attempt at making gerber files for a PCB fab house. I am unsure about some very simple things. I was using the Eagle board editor and for the holes I set them at .35mm diameter but in the board view there is also a square around the hole like in the attached picture. What does the square represent?
FYI the layers selected for viewing are Pads and Holes. Which are the only layers I plan to include in the finished gerber file since this is an inductor coil PCB. Is that ok to do?
