Export a board for JLCPCB assembly

K is kicad-cli (see kicad-view). Gerbers come from kicad-fab-export.

What JLC accepts

From JLC's help center, read on 2026-11-05:

• BOM: columns Comment, Designator, Footprint and JLCPCB Part #.
  • Separate designators with commas, with no ranges and no repeats.
  • Put at most 200 designators in one row.
  • Use csv, xls or xlsx.
• CPL: columns Designator, Mid X, Mid Y, Layer (Top/Bottom) and Rotation.
  • Positions are in mm. Rotation is in degrees, counter-clockwise positive.
  • Put both sides in one file.
• Both files:
  • JLC places a part only if its designator appears in both files, matched exactly, including case.
  • The CPL and the Gerbers share one origin. The jobsets use KiCad's absolute origin, so if you change use_drill_place_file_origin, change the Gerber job's use_drill_origin to match.
