UV exposure and PCB wytrawiarka




Quite by accident I came across a long time ago on video in YouTube, which focuses on domestic production of PCBs. Personally, I am convinced that it is better to perform the PCB in a professional company – you know: aesthetics, double-sided layout, descriptions, solder mask, tin holes etc. But for small, home projects, not specifically require it. Do not forget that it comes to the cost of a few dozen gold and długaśny waiting time. So I decided to make myself the right tools to perform such fototransferu tiling method, ie UV platesetter and wytrawiarki PCBs.

UV exposure and PCB wytrawiarka




People tracking me on Google+ or Facebook on a regular basis could observe the progress of project development, so this entry will treat about how the project was created and its final outline.

UV exposure

  • The head of the UV LED 30W
  • OLED display 1.3 “
  • Control via the illuminated encoder RG
  • UV LED Cooling Peltier TEC1-12710
  • An independent temperature measurement of UV LEDs and heat sink
  • Active cooling heat sink fan
  • Dew point with a sensor SHT11 (air humidity, ambient temperature)
  • LED Driver LDU4860S1000 with an efficiency of 95% and PWM control
  • UV LED power adjustment range 0 ÷ 100%
  • Monitoring operating parameters using UV LEDs INA226 (voltage, current and power)
  • Step-Up Converter 36V
  • Efficient, low-profile power supply Mean Well RPS-320-12 power of 320W
  • The driver is based on ATmega328P / Arduino IDE

Wytrawiarka

  • Aquarium of working age, with a capacity of 1.6 liters
  • OLED display 1.3 “
  • Control via the illuminated RGB encoder
  • The ability to digest the two PCB 120mm / 120mm
  • The total power output of 120W (4x30W)
  • Two-channel heating system (for heating and maintaining the temperature)
  • Continuous temperature measurement solution
  • The aeration system: mixing, cooling
  • The driver is based on ATmega328P / Arduino IDE
