  • Aperture/Dcode file (if not RS274X)
  • Excellon Drill file
  • Drill Tool list (if not embedded within NC Drill file)
  • Solder mask Top & Bottom (for 2-day lead times) - positive polarity
  • Silkscreen 1 or 2 sides - positive polarity

 

4-layer circuit boards require the following gerber files:

  • Top & Bottom - positive polarity
  • 2 inner layers: polarity based on design
  • Aperture/Dcode file (if not RS274X)
  • Drill Tool list (if not embedded within NC Drill file)
  • Solder mask Top & Bottom  - positive polarity
  • Silkscreen 1 or 2 sides - positive polarity
