Gerber job file (.gbrjob)

Small file KiCad exports alongside Gerbers describing the stackup, thickness and layer order, so the fab reads intent not guesses.

How it looks

Real text: from the CORE3588 fab pack
{ "GeneralSpecs": { "Size": { "X": 86.55, "Y": 101.05 }, "LayerNumber": 4, "BoardThickness": 1.55, "ImpedanceControlled": true }, "DesignRules": [ { "Layers": "Outer", "TrackToTrack": 0.2, "MinLineWidth": 0.12 } ]}
Lines from core3588-job.gbrjob in our PCB Power fab pack (shortened). It is plain text that machines and people can both read.

How it works

ONE FAB PACKF.CuIn1In2B.Cumasksilkedgeone Gerber file per layer: shapes only.gbrjobplus one small job file that describes them allorder of layers, board size and thickness,which files are which, the design rules

Where it fits

Part of the fab pack with the Gerbers, drill files and IPC-D-356 netlist.
