Turn a simple old pizza oven into a professional SMD reflow oven with a sleek touchscreen interface and modern PID temperature control  /All files are attached/

Why This Oven?

·       Achieve clean and reliable soldering without damaging components or PCBs.

·       Full control over the heating process with step-by-step temperature management.

·       Perfect for hobbyists, makers, and electronics enthusiasts.

How It Works:

·       Precise Temperature Control:

·       The heating cycle is divided into four stages: Preheat, Soak, Reflow (Peak), and Cooling.

·       A PID controller reads the temperature from a thermocouple and adjusts the heater

current to maintain the perfect temperature at each stage.

Step-by-Step Heating Process:

·       Preheat: Gradually warms the PCB to prevent thermal shock.

·       Soak: Ensures uniform heat distribution for even soldering.

·       Reflow (Peak): Melts the solder completely to secure all components.

·       Cooling: Gradually cools the board to complete the soldering safely.

Key Components:

·       Oven Heater: Provides stable heat.

·       MAX6675 Thermocouple Sensor: Monitors temperature accurately.

·       STM32 Microcontroller: Controls the heating profile and touchscreen interface.

·       Solid State Relay (SSR): Ensures precise and fast heater switching.

·       Touchscreen Display: Easy access to program settings and real-time monitoring.
