For only PCB production we need PCB layout data(standard Gerber, or extended Gerber, or Gerber X2, or ODB++, or IPC-2581 for artwork, and/or Excellon, or Sieb & Meyer 1000, or Sieb & Meyer 3000 for drill file) and fabrication drawing. For PCBA order except what is needed for PCB production, we also need centroid data, BOM(.xls, .xlsx, .csv, .txt), and assembly drawing.
