PCB Gerber File Checklist

1-Layer PCB Checklist for Gerber Submission (RS-274-X Format Recommend)
  1. Drill file in Excellon Format (Plated and un-plated 2 drill files are the best)
  2. Copper Layer Gerber File
  3. Soldermask Gerber File (optional)
  4. Silkscren Gerber File (optional)
  5. Board Outline & Milling Layer Gerber File (All cutout and milling is under this single Gerber layer)
  6. Readme.txt (optional, recommended)

Please make sure:
No layers are mirrored; If the PCB need to be V-scored, the clearance to the edge PCB must be 1/4 of the PCB thickness. For example, if the board is 1.6 mm thickness, the clearance must be at least 0.4 mm. If the PCB need not V-scored, it means need to be routed (CNC), the clearance must be at least 0.25 mm. If your files are RS-274-D Gerber format, then please include the aperture file.

  4. Top Copper Layer Gerber File
  5. Bottom Copper Layer Gerber File
  6. Bottom Soldermask (optional)
  7. Bottom Silkscreen (optional)
