Ever want to make a uv lightbox to expose your PCB?
I gone explain how you make a handy and professional lightbox for less money.
UV light is bad for your health, avoid long exposure to UV light
UV-A lamps are best to use for your light box.
UV-B are the most harmful to your health, do not use these lamps.
UV-C: This lamps are too weak to expose your boards.

Step 1: Materialen / Materials

Step 2: Hout Afmetingen / Wood Dimensions
The reason that I've chosen MDF is because it has a nice smooth surface and its easy with finishing.(and its cheap.)
A - 530x340x15
B - 530x340x15
C - 560x340x15
D - 340x105x15
E - 560x60x15
F - 560x120x15
G - 300x30x15
H - 530x35x4
Part 'B' has on both sides a groove of 15mm deep and 6mm high.(see photo)
the groove also depends on the guides that are going to use.
Step 3: MDF Bak / MDF Case
Once your wood is cut to shape you going to make the case, see photos for further instruction.
Step 4: Elektronica / Electronics
total 8 fluorescent lamps, 4 Transformer and 8 Starter
on the pictures you can see how I connect the lights and switch.
Step 5: Lade / Drawer
Now we make the drawer with a layer of foam and glass.
See photo's for further instruction.
Step 6: Einde / Finish
Last your gone mount the MDF box on the tray with screws on the sides,
the reason you do that with screws is that when a lamp is broken you can replace it.
