TwinTeeth: The PCB mini-factory

TwinTeeth-The-PCB-Mini-Factory

Diyouware TwinTeeth, an open-source PCB mini-factory :

It includes the following functions:

  • UV Laser photoengraving on sensitive film or presensitized boards using an ultraviolet laser.
  • Drilling vias and holes using any mini-rotary tool like Dremel® or Proxxon®
  • Dispensing solder paste with precision on SMD PCB pads
  • Plotting circuits with a permanent pen-maker (if you prefer this method)
  • 3D printing knobs, casings, front-panels, even print circuits with conductive filament, or make circuits supports
  • Milling/Carving soft materials or etching PCB copper with a v-bit (if you prefer this etching method)
  • And much more… because it is extendable and you can use any other tool you can fix on it

  1. With the right lasers and filters, you could generate computer graphics – on film. Long exposures while moving a light source were the original methods of printing to film.

    1. I doubt you’d get anywhere with thr traditional approach – for that you’d need a small arsenal of dynamically exchangeable optics for the various apertures etc. However, I’m now starting to wonder how well an “isolation milling” type approach would work adapted to a focused UV laser and a standard UV-sensitive PCB… I mean you’re bound to get better consistency of isolation gap width than with a v-tip stylus, surely? Of course, you’d still need to chemically develop the thing… :(
