Homebrew PCBs

That's an interesting idea...  

You can only focus UV light just as much as you can focus visible light, but there are cheap lasers that emit light in the UV range.  I believe the lasers used in DVD players emit light in the UV range, but don't quote me on that.

  Subject: [Homebrew_PCBs] CNC and UV leds


  Hi all.

  I recently saw a few articles on using UV leds to expose photoresist
  type boards and have to admit, I have tried various methods and am going
  to try this one. I also did a quick search in this list archives before
  starting this thread.

  I was wondering in one could concentrate the UV light from a LED via a
  lens like in the laser pointers and create a pin point uv light. Then,
  in making a CNC type machine (yes I belong to the cnc groups as well)
  use this method to simply draw the tracks onto the board directly. One
  would have to create a test run every sop often but I wouldn't mind
  seeing anyone elses posts if they have tried this.
