File Requirements

1. PCB Gerber files

PCB Gerber files exporting should be in RS-274X format and contain the following file:

  • pcbname.GTL                 Top Layer
  • pcbname.GTS                 Top Solder Mask 
  • pcbname.GTO                Top Silkscreen
  • pcbname.GBL                 Bottom Layer
  • pcbname.GBS                Bottom Solder Mask
  • pcbname.GBO                Bottom silkscreen
  • pcbname.GML/GKO       Board Outline
  • pcbname.TXT                 Drills
  • pcbname.GL2                 Inner Layer (for 4 layer only) 
  • pcbname.GL3                 Inner Layer (for 4 layer only)

2. BOM (Bill of Materials)

Your BOM file should be in csv, xls, xlsx format, and the following must be included:

  • Parts ID: the location of the component, it is also named of "Designator / Location / Reference" in different PCB design tools.
  • Part Number: manufactured part number of the part
  • Quantity: the corresponding quantity of a component in a BOM
  • Type: solder type of the component, SMT = surfaced mounted technology, THT =  through hole technology
  • Pins/Pads: pins/pads of the component, for example the 0603 capacitor C0603X104K5RAC3316 has 2 pads, the part type is SMT.
