Hi all,
woud it be possible to make a small projector and use a UV light source? The idea is to use this to expose PCB boards, without having to go through the printing of transparancies.
Would this work?
I was concerend about the resolution, some of the really fine traces might be a problem., the other is that the lcd wont have enough UV blocking.
Could anyone she some light on the subject? 🙂

I am quite sure that LCD units will NOT block UV light at all. Perhaps that's why all the projector bulbs have to use expensive UV-blocking quartz glass inside?
There are some bulbs for medical use that can produce some pretty high output UV light, but this is quite a lot of overkill for a photosensitive board developer. A commercial projector is also quite a lot of overkill, I suppose. I would have a look at some of the DIY projector projects, perhaps there's one out there that could be adapted to work with a LED bank as the UV light source?
Maybe a DLP engine would work better than a LCD panel? 😕
-HTH
