KiCAD JLCPCB tools

Plugin to generate all files necessary for JLCPCB board fabrication and assembly

• Gerber files
• Excellon files
• BOM file
• CPL file

Furthermore it lets you search the JLCPCB parts database and assign parts directly to the footprints which result in them being put into the BOM file.

Warning 🔥

I try to keep it working with 7.99 nightly builds but there are massive API changes on the horizon and I'm not sure if I can keep up with them.

This is under a lot of developments, so consider this README out of date all the time 😏

If you find any sort of problems, please create an issue so that I can hopefully fix it!

Installation 💾

KiCAD PCM

Add my custom repo to the Plugin and Content Manager, the URL is https://raw.githubusercontent.com/Bouni/bouni-kicad-repository/main/repository.json

From there you can install the plugin via the GUI.

Git

Simply clone this repo into your scripting/plugins folder.

Windows

cd C:\users\<username>\Documents\kicad\<version>\scripting\plugins\  # <username> is your username, <version> can be 6.0, 7.0, or 7.99 depending on the version you use
git clone https://github.com/Bouni/kicad-jlcpcb-tools.git

Linux

cd /home/<username>/.local/share/kicad/<version>/scripting/plugins  # <version> can be 6.0, 7.0, or 7.99 depending on the version you use
git clone https://github.com/Bouni/kicad-jlcpcb-tools.git

Linux

cd ~/Library/Preferences/kicad/scripting/plugins
git clone https://github.com/Bouni/kicad-jlcpcb-tools.git

You may need to create the scripting/plugins folder if it does not exist.

Flatpack ⚠️

The Flatpak installation of KiCAD currently dows not ship with pip and requests installed. The later is required for the plugin to work. In order to get it working you can run the following 3 commands:

1. flatpak run --command=sh org.kicad.KiCad
2. python -m ensurepip --upgrade
3. /var/data/python/bin/pip3 install requests

See issue #94 for more info.

Usage 🥳

To access the plugin choose Tools → External Plugins → JLCPCB Tools from the PCB Editor menus

Checkout this screencast, it shows quickly how to use this plugin:

Keyboard shortcuts

Windows can be closed with ctrl-w/ctrl-q/command-w/command-w (OS dependent) and escape. Pressing enter in the keyword text box will start a search.

Toggle BOM / CPL attributes

You can easily toggle the exclude from BOM and exclude from CPL attributes of one or multiple footprints.

Select LCSC parts from the JLCPCB parts database

Select one or multiple footprints, click select part. You can select parts with equal value and footprint using the Select alike button. In the upcoming modal dialog, search for parts, select the one of your choice and click select part. The LCSC number of your selection will then be assigned to the footprints.

Generate fabrication data

Generate all necessary assembly files for your board with a simple click.

A new directory called jlcpcb is created, and in there, two separate folders are created, gerber and production_files.

In the gerber folder all necessary *.gbr and *.drl files are generated and zipped into the production_files folder, ready for upload to JLCPCB. The zipfile is named GERBER-<projectname>.zip

Also in the production_files folder, two files are generated, BOM-<projectname>.csv and CPL-<projectname>.csv.

Footprints are included into the BOM and CPL files according to their exclude from BOM and exclude from POS attributes.

Footprint rotation correction

JLCPCB seems to need corrected rotation information. @matthewlai implemented that in his JLCKicadTools and I adopted his work in this plugin as well. You can download Matthews file from GitHub as well als manage your own corrections in the Rotation manager.

Icons

This plugin makes use of a lot of icons from the excellent Material Design Icons

Development

1. Fork repo
2. Fit clone forked repo
3. Install pre-commit pip install pre-commit
4. Setup pre-commit pre-commit run
5. Create feature branch git switch -c my-awesome-feature
6. Make your changes
7. Commit your changes git commit -m "Awesome new feature"
8. Push to GitHub git push
9. Create PR

Make sure you make use of pre-commit hooks in order to format everything nicely with black In the near future I'll add ruff / pylint and possibly other pre-commit-hooks that enforce nice and clean code style.
