| **JLC PCB Plug-in for KiCad** |
|:-----:|
[](https://github.com/sponsors/bennymeg)
## Features
1. Generates gerber files in correct format for production
2. Generates BOM file in correct format for production
3. Generates Pick and Place file in correct format for assembly
4. Generates IPC netlist file
## Installation
### Official Installation
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.
### Manual installation
Download the [latest release](https://github.com/bennymeg/JLC-Plugin-for-KiCad/releases) ZIP file. Open the "Plugin and Content Manager" from the KiCads main window and install the ZIP file via "Install from File".
## Usage
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 (unless disabled). _(since v3.0.0)_.
## Options
Options can be set in the dialog that appears when the plugin is invoked. They are saved in a file called `fabrication-toolkit-options.json` in the project directory so that they are remembered between invocations of the plugin.
☑ __Additional layers__: Comma-separated list of additional layers to include in the gerber archive.
☑ __Set User.1 as V-Cut layer__: Merge User.1 layer with the Edge-Cut layer in production.
☑ __Apply automatic translations__: Apply known translation fixes for common components.
☑ __Apply automatic fill for all zones__: Refill all zones before generation production files.
☑ __Exclude DNP components from BOM__: Exclude components the had been set a DNP from th BOM.
### ① Include Component Part Number in Production Files
Add an 'LCSC Part #'* field with the LCSC component part number to the symbol's fields property.
#### Primary Fields*:
| 'LCSC Part #' | 'JLCPCB Part #' |
| --- | --- |
_The fields will be query in the order denoted above._
#### Fallback Fields*:
| 'JLC Part' | 'LCSC Part' | 'LCSC' | 'JLC' | 'MPN' | 'Mpn' | 'mpn' |
| --- | --- | --- | --- | --- | --- | --- |
_The fields will be query in the order denoted above._
---
### ② Ignore Footprint in Production Files
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.
---
### ③ Offset Component Rotation
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.
#### Primary Fields*:
| 'JLCPCB Rotation Offset' |
| --- |
_The fields will be queried in the order denoted above._
#### Fallback Fields*:
| 'JlcRotOffset' | 'JLCRotOffset' |
| --- | --- |
_The fields will be queried in the order denoted above._
---
### ④ Offset Component Position
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 0.0635mm (= 1/400in) shift.
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.
#### Primary Fields*:
| 'JLCPCB Position Offset' |
| --- |
_The fields will be queried in the order denoted above._
#### Fallback Fields*:
| 'JlcPosOffset' | 'JLCPosOffset' |
| --- | --- |
_The fields will be queried in the order denoted above._
### ⑤ Override Component Layer
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`.
#### Primary Fields*:
| 'JLCPCB Layer Override' |
| --- |
_The fields will be queried in the order denoted above._
#### Fallback Fields*:
| 'JlcLayerOverride' | 'JLCLayerOverride' |
| --- | --- |
_The fields will be queried in the order denoted above._
