Is there a SparkFun Eagle DRC file?

I’m going to be submitting my first PCB board in the coming week and was curious if there is a SparkFun DRC file for Eagle. If not, I’d be happy to take a stab at making one.

Not really. We don’t use Eagle here in the office, so I’m not comfortable creating one.

If you’d like to create one, I’d love to have it. I can post it on the PCB page.

is the primary list of DRC rules the one under “PCB Specifications” at the link below?

could any eagle users comment on whether the default eagle DRC are sufficient for submission to sparkfun?

This is what I made for Gold Phoenix PCB’s Eagle DRU file:

    Note the one thing Eagle doesn’t check- and this is a pain- is top silkscreen over the top SMD pads. This totally sucks, if text is printed over the pads you can’t put the device over it. It is repairable by scraping it off, however.

    You’ve had a problem with this? I usually just solder straight through the silkscreen. Now if the soldermask is covering a pad, that’s something else.

    Also, I’ve noticed gold phoenix will bump silkscreens to avoid vias and some pads. Not sure if they do it on our customer/batch panels, but they do a nice job with the seperate SFE designed PCB orders.
