Lines or Shapes Detected in GM Layer – Slot Definition Unclear

Reason for Failed Review:

Your design includes lines or shapes in the GM layer, but the slot information is not placed in a separate outline layer. This makes it unclear for PCBfast’s engineering team to identify which features should be treated as slots or mechanical outlines, which may lead to fabrication errors.

PCBfast Suggestions:

1. Please add a remark in the “Special Requirements” section when placing your order, which will help our engineers quickly verify your design intent.

2. Alternatively, you can rename the corresponding layer to “Slot” or another clear label to make the slot data easier to identify.

Following these guidelines ensures accurate mechanical processing and prevents delays during engineering review.
