File Requirements

1. PCB Gerber files

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

  • 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, or xlsx format, and must include the following:

  • Part ID: the location of the component, (some PCB design softwares call this Designator, Location, or Reference)
  • Part Number: manufacturer part number of the component
  • Quantity: the corresponding quantity of a component 
  • 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.
