- Process Control: Delivered ±3°C closed-loop thermal accuracy for reliable custom PCB manufacturing, implementing a full PID algorithm in hand-written A51 assembly.
- Thermal Stability: Eliminated dangerous temperature overshoot using precision PWM output modulation combined with FSM state logic governing the reflow profile stages (preheat → soak → reflow → cooldown).
- Data Validation: Streamlined tuning and telemetry analysis with a custom Python live-plotting GUI that receives serial thermocouple data and displays the thermal profile in real time.
