Fabrication Files

1. Gerbers

   File -> Fabrication Outputs -> Gerbers (.gbr)

   Output directory: ../documentation/fabrication/gerbers

   Include Layers:

   • F.Cu
   • F.Paste
   • F.Silks
   • F.Mask
   • F.Fab
   • B.Cu
   • B.Paste
   • B.Silks
   • B.Mask
   • B.Fab
   • Edge.Cuts - (contain the board outline/cutouts.)
   • In1.Cu, In2.Cu … - (needed for 4/6 layer designs.)

   Options:

   • Select Plot reference designators, otherwise designators will not appear on silkscreen layers.
   • Select Check zone fills before plotting
   • Select Use Protel filename extensions, this is recommended as JLCPCB prefers Protel filename extensions.
   • Select Subtract soldermask from silkscreen, this ensures no silkscreen on pads.
   • Coordinate format 4.6 unit mm

2. Drill and Map Files

   Output directory: ../documentation/fabrication/gerbers

   Options:

   • Excellon drill file format
   • Check Use alternate drill mode for "Oval Holes Drill Mode".
   • Check Absolute for "Drill Origin".
   • Check Millimeters for "Drill Units".
   • Check Decimal format for "Zeros Format".
   • Gerber X2 map file format

   Zip gerber files

   zip ./documentation/fabrication/gerbers.zip ./documentation/fabrication/gerbers/*
   

3. BOM

   Generate BOM from schematic editor using blank command line to create bom xml file.

   File -> Fabrication Outputs -> Component Placement (.pos)

   Output directory: ../documentation/fabrication/

   Settings:

   • Format = CSV
   • Units = Millimeters
   • Files = Single file for board
   • Do not use drill/place file origin

   Modify pos files:

   • Ref -> Designator
   • PosX -> Mid X
   • PosY -> Mid Y
   • Rot -> Rotation
   • Side -> Layer

5. Step

   File -> Export -> Step

   Output directory: ../documentation/3dmodels/pcb.step

   • Drill/place file origin
   • Overwrite old file
   • Standard Board outline chaining tolerance
