Process for generating a JLC pick-and-place file

Exporting data

From EDG: export with NetlistGenerator.py set to refdes mode and LCSC parts

From KiCad: export both BoM and footprint position files (in CSV)

Post-processing data

Script

The jlcpcb_pcba_postprocess.py automates the below steps.

Note that other plugins depend on a schematic with a LCSC field, whereas currently this writes the LCSC part number in the value field.

Manual post-processing

Post-process BoM CSV:

• Replace ; with , to make it an actual CSV
• Rename these columns:
  • Designation -> JLCPCB Part #
• Add a Comment column

Post-process position CSV:

• Rename these columns:
  • Ref -> Designator
  • PosX -> Mid X
  • PosY -> Mid Y
  • Rot -> Rotation
  • Side -> Layer
• Diodes may need a 180 rotation
