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. Exposure 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 (and also traces with less than 10 mils between them) will need careful judging of exposure/development/etch times.
