The Reflow Soldering Oven with LCD Display
Description:
One of SMD soldering techniques is using a reflow soldering oven. Reflow soldering technique is used when it is impossible to solder components by hand. These may include ball grid arrays (BGA), small pitch quad flat packs. Or simply solder any SMD element to make board look professional and smooth.
Soldering oven controller is based on AVR microcontroller that uses ADC input to read NTC temperature sensor. Current temperature is displayed on graphical LCD as chart. As authors state - system works OK, maybe additional blower could be added for cooling speed controlling as without fan it is to slow.
Micro controller:
ATMega32
