UV exposure blah

  • 54 x UV led @ 20mA
  • 18 x 82ohm resistor

Soldering caused unwanted increase of resistance, so resistors needs to be changed to 50 ohm.

How to

  • best exposure time seems to be 12.5 min in the distance of 20 cm.
  • for homogeneous exposure change the position of PCB at least one times.
