Lightbox for Expose PCB

Introduction: Lightbox for Expose PCB

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


- Two face tanner, total 8 UVA lamps (4 UVA lamps is more than enough, but if you want to illuminate printboard faster or larger 8 lamps much better )
- 15mm MDF
- digital Timer (with countdown function)
- swith on/off
- Glass ( glass from a picture frame) 40x30 cm
- + 5mm foam 56x32 cm
- Aluminum foil or mirror 30x30 cm
- Two-drawer slides
- piano hinge 40 cm
- Screws 3.5x35
- Wood Glue
- close contact glue
- plug
- electric wire
- 4 rubber legs

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.)

MDF Parts:


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

I use 2 face thanners.
total 8 fluorescent lamps, 4 Transformer and 8 Starter

on the pictures you can see how I connect the lights and switch.

LED schedule:

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.

See photo's for futher instruction.

Step 7: Eind Kosten / Final Cost

The price is an average of the most important things you need, many of these things you have lying around or you can get somewhere cheap.

- Two face tanner, total 8 UVA lamps - euro 8.00
- 15mm MDF - euro 7.50
- Digital timer (with countdown function) - euro 6.99
- Switch on / off - euro 1.00

    I appreciate this. Giving the text in both languages is helpful. I do not think the translation program got "expose your boards" right. In the Dutch text where 'boards' appears in the English translation, the original word is usually belichten, which I understand to be illuminate. It is the same in German as Dutch. But, boards are slabs of flat wood.

    I think the right word is expose (belichten) instead of illuminate (verlichten). I think a Instructable shout be in English be course this is an English site. However I speak Dutch there are many language I don't understand. So keep the site only in English please.

    David, I am not sure what English word to suggest because I was not certain of the meaning of the Dutch word "mee." Perhaps it is the same as the English word "me." Do not worry about your English. I have visited Germany and tried to communicate in German. Speaking (or writing) in another language is difficult.

    I come from the Netherlands, I think it is important that people from the Netherlands also understand my instruction.

    I just looked at this again. I think you changed the title. Now the reference to 'board' makes sense.
