Pad diameter on board doesn't match pad diameter in library package

Former Member

Greetings! Hoping someone can help me with a strange issue.

 

I've created a new device in Eagle 7.6, where the holes are fairly close to each other. I've adjusted the hole diameter and pad dimensions, but the size of the pad doesn't seem to be carrying over correctly to the package in my board. here's a screenshot of the pad/hole dimensions:

And in my library package, everything looks correct:

But when I place the device in my schematic and generate the board, the pad dimensions have "grown" significantly.

I read in another thread that the DRC could be overriding these values - so I opened the DRC rules I've been using (OSHPark) and tried setting the top/inner/bottom pad min to 0mil in the "Restring" options - just to see if this was what was causing the issue, but no change.

 

So anyway, I hope that someone can give me some advice as to what I might be doing wrong.

 

Thanks much!

    The Restring Pad % was definitely the problem. I reduced it from 25% to 15% and I'm no longer experiencing overlap of the pads. Of course, now this means that I've modified the DRU file from OSHPark, so now I need to find out if that means I won't be able to have the boards fabbed through them.

     

    I've reached out to their support email to see if it's OK if I adjust that value (and what the minimum would be), so when I hear back I'll be sure to post the results.

     

    Thanks again for pointing me in the right direction!
