Input data

Accepted data formats for PCB layout data are:


  • Gerber RS-274X (Extended Gerber with embedded apertures - developed by Gerber Systems)
  • DPF (Dynamic Process Format - developed by Ucamco NV)
  • Gerber RS-274D (Standard Gerber with a separate aperture file - developed by Gerber Systems)
  • Eagle .BRD file (CAD-data from CADsoft now Premier Farnell)

Artwork means all copper layers, soldermask and legend layers, board outline or mechanical layer, SMD paste layers,carbon layers, peel-off layers, etc.


  • Excellon (1 or 2) + appropriate tool list (ideally embedded)
  • Sieb&Meyer + appropriate tool list (ideally embedded)
  • Gerber format RS-274X or RS-274D (only true drill data, not a drill map)
  • DPF (only true drill data, not a drill map).
