printed circuit board exposure

[Paul Perry]

Rob, I saw somewhere that most 'blacklites' for posters etc have
only the 'near UV' & wont expose a board.

You will have to make a 'test strip' by moving a metal sheet
around so that you have exposures of 30 sec, i, 2,...64 minutes.

I'm using press&peel blue for my prototypes, BTW.

If yu DO go the sun route, the forst thing to build might be an integrating 
UV exposure meter! (not joking)
