V-Scoring Line or Slot Placed in Silkscreen Layer – Layer Misuse Detected

Reason for Failed Review:

Your design shows V-scoring lines or slots drawn in the silkscreen (or copper/soldermask) layer.

However, V-scoring lines and mechanical slots must be placed in a separate mechanical or outline layer.

If they remain in the silkscreen or copper layer, PCBfast’s system will treat them as graphics, and they will not be processed as actual cuts or scores during fabrication.

PCBfast Suggestions:

Please move all V-scoring lines or slots to a dedicated outline layer (such as GKO or GM1).

This ensures our engineering team correctly identifies and produces them as mechanical features rather than printed markings.

Following this rule guarantees accurate scoring or slot cutting and prevents production delays.
