- Generates gerber files in correct format for production
- Generates BOM file in correct format for production
- Generates Pick and Place file in correct format for assembly
- Generates IPC netlist file
Fabrication Toolkit is distributed with the official releases of KiCad 6+. Open the "Plugin and Content Manager" from the KiCad main menu and install the "Fabrication Toolkit" plugin from the selection list.
Download the latest release ZIP file. Open the "Plugin and Content Manager" from the KiCads main window and install the ZIP file via "Install from File".
Click on the Fabrication Toolkit 
button on the top tool box inside KiCad pcb editor (pcbnew).
⊛ Ensure your board is syncronized before invoking this addon [F8].
⊛ The User_1 layer in internally defined as a V-Cuts layer, please avoid using it for anything else. (since v3.0.0).
Add an 'LCSC Part #'* field with the LCSC component part number to the symbol's fields property.
| 'LCSC Part #' | 'JLCPCB Part #' |
|---|
The fields will be query in the order denoted above.
| 'JLC Part' | 'LCSC Part' | 'LCSC' | 'JLC' | 'MPN' | 'Mpn' | 'mpn' |
|---|
The fields will be query in the order denoted above.
Select 'Exclude from board' or 'Exclude from BOM' in the symbol's attributes property in order to ignore the footprint from the relevant file.
Select 'Exclude from position files' or 'Exclude from BOM' in the footprint's fabrication attributes property in order to ignore the footprint from the relevant file.
The rotation of components in KiCad Footprints does not always match the orientation in the JLC library because KiCad and JLC PCB used different variation of the same standard. Most of the rotations may be corrected by the rotations.cf definitions. To the exception cases: add an 'JLCPCB Rotation Offset' field - with positive values indicating counter-clockwise orientation offset in degrees.
If the JLC preview shows a footprint like this, enter a rotation offset of -90 to rotate pin 1 to the lower right corner.
As the rotation offset is entered in the Schematic Editor, make sure to update your PCB with the changes made to the schematic before generating a new set of production files, otherwise your changes won't be reflected.

The position of components in KiCad Footprints does not always match the orientation in the JLC library because KiCad and JLCPB used different variation of the same standard. To the exception cases: add an 'JLCPCB Position Offset' field with an comma separated x,y position offset to correct it.
Use following table to quickly find out to which coordinate enter the correction based on JLC arrows clicks - depending on footprint rotation in Kicad PCB Editor status bar:
| Kicad footprint deg | x | y |
|---|---|---|
| 0deg, Front | right arrow | up arrow |
| 0deg, Back | left arrow | down arrow |
| 180deg, Front | left arrow | down arrow |
| 180deg, Back | right arrow | up arrow |
| 90deg, Front or Back | up arrow | left arrow |
| -90deg, Front or Back | down arrow | right arrow |
For custom angles it's best to place also a temporary straight symbol to perform alignment. Single arrow press in JLC is about 0.07mm shift (8 clicks is about 0.5mm).
As the position offset is entered in the Schematic Editor, make sure to update your PCB with the changes made to the schematic before generating a new set of production files, otherwise your changes won't be reflected.

Some footprints may have their components defined on the opposite layer to there actual footprints. In these instances you can override mount side by using this field.
Values can be top, bottom, t or b.
