Gerber Files Are Not Complete

Reason for Failed Review:

Your submitted Gerber files are incomplete — they are missing one or more of the following essential layers:
Board Outline / Copper Layer / Solder Mask Layer / Silkscreen Layer / NC Drill File.

However, the order details indicate that these layers are required, and there is no remark or explanation provided to clarify their absence.

PCBfast Suggestions

A. Missing Board Outline

Please add a board outline layer to your Gerber files. The board outline defines the shape and dimensions of the PCB, and without it, production cannot proceed.

B. Missing Solder Mask / Drill / Silkscreen Layers

If your design does not include any of these layers, please select “None” for the corresponding options when placing your order online. This helps our engineers understand that the absence of these layers is intentional.

C. Missing Copper Layer

If a certain copper layer is intentionally empty, please add a note specifying which layer(s) should remain blank (e.g., “no bottom copper”).
