Missing Fiducial Marks or Tooling Holes on Breakaway Rails

Reason for Failed Review:

According to your order note, the board is designed as a 2×2 panel with V-scoring and breakaway rails.

However, the breakaway rails do not include fiducial marks or tooling holes, and it is unclear whether PCBfast should add them or leave them out.

This information is necessary to ensure accurate alignment during SMT assembly and panel handling.

PCBfast Suggestions:

When uploading your panelized Gerber files, please clearly specify the panelization requirements in your order details. For example:

•  “2×2 panel by V-scoring, 5 panels (20 pcs total), with 5 mm breakaway rails on all 4 sides, include 1 mm fiducial marks and 3 mm tooling holes on each rail.”

•  Or “2×2 panel by V-scoring, 5 mm breakaway rails on 4 sides, no fiducial marks or tooling holes required.”

Providing these details helps PCBfast’s engineering team produce your panels exactly as intended and avoid production delays or layout misunderstandings.
