Which Layer Should Be Used for Round or Irregular Cutouts

Reason for Failed Review:

Your design includes rectangular and round shapes placed in the drill drawing (DRD) layer.

These features appear to be cutouts or slots, but since they are located in the DRD layer rather than a mechanical layer, they could be overlooked during production.

PCBfast needs confirmation to ensure these shapes are processed correctly.

PCBfast Suggestions:

•  For any round, rectangular, or irregular cutouts, please place them in the GKO or GM1 mechanical layer.

•  This ensures our CAM engineers recognize and process them as milled cutouts rather than drill marks.

•  You may also add a note in the “Other Special Request” section to remind PCBfast.

Following this method ensures all slots and cutouts are correctly identified and fabricated according to your design intent.
