UV box for PCB

     My idea was to build a UV box for PCB with dimension 29 x 18 cm.

     First step was with only 90 UV led diodes and will increase the number to 135 UV led diodes soon.

     I use 2 x 1 Kohm/0,25W in parallel for 20 mA current for each diode

     12.80 Volts  at 1,9 Amps PSU used

    

     18 mm grid squares and 80 mm to focus.

     First test with 90 pieces UV leds

    

     MDF box : 29 cm x 18 cm (internal dimension)

                     : 10 cm high

    

    135 piecers UV leds   (135 pieces x 0.020 A/piece = 2.70 A)

   

     wood works = glue and screw

      

                                                                                                             3 mm clear glass mounted

                                 

     Final Project
