I’m really interested in upgrading my two sided exposure box to this kind of solution, but i have a doubt. Has anyone figured out where the Electrolitic capacitor (2200uF and 30v recover) is fitted? Looks like that is the working voltage of the capacitor, of course higher is fine (just not lower). Your use of this website constitutes acknowledgement and acceptance of our Terms & Conditions.

UV flashlights is widely used in: fluorescent penetrant testing, fluorescent magnetic particle inspection, fluorescent leak detection, Criminal Investigation detection, UV curing, archaeological research, mineral test, jewelry appraisal. These LEDs have narrow ray (+-10 degrees), it helps to get sharp shadow on photoresist even if photomask is not cling to the PCB very tight. That transparent box, although cool looking, makes me think you are asking for eye cataract. Normal glass usually absorbs too much of UV radiation, although I’m not sure if this is a problem around 400nm, or only for shorter wave lengths. After some tests, it worked awsome with Positiv20 as with pre-sensitized PCB boards that i had at home.


Because the current on which these leds( uv ultrbright 7000mcd – 400nm) operate is 20mA at 12V.
LEDs mounted close to each other, so it provide well distributed light even with small deepness of box.
