My favorite method of making PCB is using photoresist ink to cover the face of the PCB. To get a smooth and even covering this centrifuge will be made.
A scrapped motor from a fan will be used. The first version will be a dirty cheap using household materials proof of concept. If it proves to be as useful as expected, then a new, improved version with a proper motor and 3d printed parts will be made.
Future plans:
- Heating ( to cure the ink)
- Exposure unit (with LEDs)
- Light table (to position the negative film)
