Hi
I have created a PCB board using Eagle and out of curiosity, sent it to Advanced Circuits' FreeDFM (www.freedfm.com) to check for "manufacturability". However, the report from the latter isn't too positive, stating potential show-stoppers like :
1) Insufficient Annular Ring : We require a minimum of .005� annular ring for vias, a minimum of .007� for component holes.
2) Insufficient Copper Spacing : we require a minimum of .005" spacing.
Thing is, I have specified min 8mils via and 12mils pad in the restring tab and at least 8mil clearance in the clearance tab in the Eagle DRC. Wouldn't that have been taken care of?
Or is there 'gotchas' that I should take note of?
Thanks!
