Description
I had been planning to build a reflow oven for quite some time, and I finally found the time to make it happen. This device is used to solder surface mount components onto a circuit board by following a temperature profile included with the solder paste.
The setup includes an external controller(Don't have to modify the inside of the toaster oven) that will precisely follow this reflow profile. Simply plug your power into the controller, then connect a toaster oven to the controller’s outlet. The controller uses a PID algorithm in the code to regulate the oven, turning it on and off to maintain accurate temperatures.
The user interface (TFT Touchscreen) allows you to customize the temperature and duration for each stage of the reflow process (preheat, soak, reflow, and cooldown) which gives you full control over your soldering workflow.
I highly recommend watching the two videos I linked. They contain invaluable information that helped build this project. I also added the .step files in case you need/want to change anything. Please share if you do!;)
Thanks for checking out my design! I truly appreciate any Boosts. Let me know in any way I can improve this design or if you need any help.
