Description

Make an UV Box for PCB etching.

Goal

  • To be able to insolate presensitized copper boards.
  • Insolate double sided copper boards.
  • Use a timer (optional)
  • Display time left (optional)

Obstacle

A list of potential obstacles

Components

  • UV LED (200x): description
  • (Alim)
  • Box (wood, suitcase,...?)

LED Panel

I propose we make an LED panel for the UV box. A guy from PTL is doing the same thing (UV Box for DNA analysis), and Sasha is interested in making a white LED panel. The panels, when bought online, cost a lot due to their large size and weight (shipping costs), but it would be fairly cheap to build them ourselves. Here are some pics of the way they are made: LED Panel assembly.jpg LED Panel cutout.jpeg Screen Shot 2013-01-23 at 10.36.42 AM.png Led panel construction.jpeg
