Reflow Oven Diagram
The PC provides GUI and control of the reflow process.
The PC also enables building, editing and storing of reflow profiles.
The real time reflow process is done by the Arduino board.
The reflow profile is preloaded into the Arduino memory.
The Arduino controls the oven filament by the SSR. The control is ON/Off type.
The Arduino gets temperature readings from the K-type thermocouple via the MAX6675 (Temperature to digital converter).
The Arduino will use degraded PID control loop. (At minimum P loop will be good enough).
During the reflow process the Arduino will send temperature readings to the PC for real time process display.
