Calum's demo used MICROTRAK single sided boards, in 35um copper thickness, 1.6mm thick board.  You can buy them here: http://www.megauk.com/pcb_laminates.php though I think they have a minimum order, rapid electronics also sells them.  Exposed to the UV light with an acetate stencil printed at any random shop for 6 minutes.  Developing and etch times will vary depending on temp and some other factors - but 2.5 minutes for developing is a decent place to start, and 10-20 minutes for etching.

Training

Training will include;

  • Cutting the board
  • Exposing it to UV using a transparancy
  • Stripping the exposed photoresist
  • Etching the board
  • Identifying errors
  • Tidying up afterwards


Training notes

Calum's demo used MICROTRAK single sided boards, in 35um copper thickness, 1.6mm thick board. You can buy them here: http://www.megauk.com/pcb_laminates.php though I think they have a minimum order, rapid electronics also sells them. Exposed to the UV light was for 6 minutes with an acetate sheet printed at any random shop. Developing and etch times will vary depending on temp and some other factors - but 2.5 minutes for developing is a decent place to start, and 10-20 minutes for etching. Traces less than 10mils in width will need careful judging of exposure/development/etch times.
