File Requirements

File Upload Requirements

All uploaded files must be either EagleCAD Board Files (.brd), or a .zip, .tar, or .tar.gz file containing your gerber files.

Eagle Board Files

If you upload an EagleCAD (.brd) we will automatically convert it to gerbers using Eagle 7.5, with standard selections for which layers to show. If you would like to customize your layers, please export your board to gerbers and upload those.

Gerber Requirements

Eagle CAM Job (7.1 and lower): PCBs_ioEagle.cam
Eagle CAM Job (Eagle 7.2+): PCBs_ioEagle7.2.cam

Gerber layer files should use the following formats and any of the following extensions, case insensative (ie: boardname.gtl for top layer copper) and MUST be zipped, tarred, or tar.gz-ed before upload.
