I am designing a board in EAGLE and where I routed my traces into the pins of openings for a header, there are all sorts of dimension errors when I run design rule check, am I missing something?
Note: The errors are only around the header openings, the rest of board is fine.
Just in case anyone else reads this in the future, the solutions was pretty common sense, I just wasn't thinking. The issue was that the holes for the header pins were too close and didn't follow the rules setup by the board house I was using.
To close to the edge of the board, right? That's the usual meaning of a "Dimension" error. If they were too close to something else, you'd probably get a "Clearance" error.
The default dimensions for Eagle are very wide - these days most boards edges are milled
so are highly accurate and you don't have to allow much clearance at the edges - edit
the design rules to a more sensible value. Ditto the minimum drill (which may be larger
than the default via hole) But that might just be my setup!
If you can get design rules that match the fab that will be making the board - fab houses
should have a list of their limits and requirements.
