Description
portable pcb etching in a box
README
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
