I'm looking at building a UV exposure box out of an old broken scanner - do you have to expose the entire board all at once, or can you do it in a sweeping motion for a longer time?
Also, where could I buy the Bungard Original PCB's?
actually i wanted to ask you guyz about the developers you use. is Sodium Hydroxide as good as the other developers like the universal developer (Sodium Metasilicate). whats the difference between the two

I use the more expensive Universal Developer, because I have only heard good news about it.
There are many website that warn to never use the cheaper Sodium Hydroxide.
Many on-line stores advertise their delevopes with CONTAINS NO SODIUM HYDROXIDE
from another on-line store:
Also unlike more hazardous developers ours has a unique built in safety factor of 50:1, thus ensuring that overdevelopment which causes image loss, thinning of tracks, undercutting etc. is almost impossible.
It seems to me that laying the board on the table, setting the pattern on top, and then laying a piece of glass or plexiglass on top would be faster and easier than clamps... Not to mention, it would ensure that the pattern lays totally flat against the entire board, not just in the areas where it was clamped...
and a piece of glass or plexi should only cost you a couple dollars at the most, if you don't have one around already.
