AETZBOX
DIY Mobile PCB Etching KIT
The Idea
Build a portable / mobile PCB etching workstation that fulfills these criteria
- waterproof
- able to etch 100x160mm double sided boards with 8mil precision
- low cost. total bill of materials should not exceed 150 CHF
- diy approach, mostly laser cut plexi and easily sourceable materials
- fits in a RAKO Box
Some guiding ideas
- use very little but always fresh chemicals
- good heat management: etching has to be done at 45-50 degrees celsius, developer has to be kept at >20 degrees as well (in my workshop, temperatures can easily drop below 16 degrees and developing is a pain).
- all material and chemicals travel in the box. liquid waste can travel in the box as well until it can properly disposed of.
- should be easy to clean. no electronics exposed to moisture.
- as few as possible switches and electrical contacts exposed to the harsh etching environment
- self illuminating

Questions
How big is the UV Leds PCB?
It measures 180 × 120 mm and has 2 copper layers, 1.6 mm thick.
What parts does the UV Leds use?
119 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the UV Leds KiCad files?
From the mirdej/etchingbox repository on GitHub, at the commit this page was made from: the board is Electronics/UV-Leds/UV-Leds.kicad_pcb and its schematic Electronics/Aetzbox-CPU/Aetzbox-CPU.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the UV Leds design in my own project?
Its repository publishes it under the GPL-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
