Double sided PCB UV LED exposure box

Here is a very nicely built double sided PCB UV exposure box made out of wood, glass and UV LEDs. Exposure time is about 2-3 minutes, but that depends on photo lacquer thickness and age.

There are two panels with 84 UV LEDs on each, that is 168 UV LEDs in total. One panel draws 700mA from a 12V source. It is recommended that 2000mcd LEDs are used with peak wavelength of 400nm. All diodes are soldered on a veroboard which was probably a great advantage since minimum of 336 holes had to be drilled.
