Next project from generalguitargadgets.com
Wanted to try UV pcb board manufacture.
Step one is to create the NEGATIVE design on an overhead film. I tried just printing from the pdf from the website but it seemd to scale to a very large picture. Copied it into MS Word and scaled it by printing and measuring the printout (there are inch scales on the pdf)..
Step 2 is to use a UV light for 3 or so minutes to 'set' the pcb tracks.
I taped the plastic on. Get it very flat onto the pcb for best results. Some people use a thin glass sheet over the top.
The clear parts on the overhead (for the type of UV pcb kit I am using) remain after you use the 'AE' resist developer. Took about 2 minutes to take the exposed plastic off the copper pcb.
Photos and more soon.
