Preparing the manufacturing files for submission Are all the traces routed? Will a via or pad mess up your silk? Is everything you care about inside the board outline? Are there any dead-end traces? If so, correct them and re-run the DRC. Do a last-minute once over on your design, and look for odd spots.EAGLE users can grab our handy OSHPark DRU file right away.Run the Design Rules Check (DRC) to verify your design against our fabrication specs.In other design tools, you may need to rebuild ground planes, fill zones, or other final steps to ensure your copper pours connect properly.In Eagle, run ratsnest one more time to make sure any airwires and ground planes are cleaned up.Add a time stamp, version number, the board name, and any other extra text you want.Nothing is worse than ordering a board, only to realize a critical component isn’t for sale. Make up your bill of materials and verify all your parts are in stock.Check footprints against the datasheet.Check connections against your schematic.With a few adjustments though, you can ensure your design comes through as expected. We can handle silkscreen logos up to 500 DPI but the process can be a little complicated. Preparing a bitmap or logo: As much as we love board art, some ways of generating it can be problematic.If you have any internal cutouts or slots, you’ll want to verify that your design tool generates them how we expect.
You can also use Gerbv to get one from a different layer. Most design tools have a special layer for this. We use that for both calculating the board size and cost, and send it to the fab for a milling guide. Preparing the board outline: We use a separate board outline file that tells us where your board edge should be.EAGLE users can load our design rules files, which contains all the DRC information.We don’t perform any design rule checking on our end, since your design tool will help you fix errors more efficiently than we can. You’ll want to enter the important information into your design tool’s DRC checker so it can verify things for you. The design rules, stackup, and specifications depend on your chosen fabrication service.Part of any great design is making sure that what you’ll get matches what you designed. Great! So are we!
