You are fully responsible for your actions, and perform them at your own risk! This may result in food poisoning, especially if you use leaded solder for your PCB's. Moreover, it is not recommended that you use the same appliance to reflow PCB's as to cook food for consumption. Take all safety precautions as necessary. Safety Disclaimer: If you are a beginner in electronics or don't have the proper experience to work with mains voltage, I would suggest that you either don't mess with it, consult a professional, or keep learning until you're proficient enough! I am not liable for any mishaps that may occur due to misuse of the Reflowduino PCB's or its associated components and electrical system (including mains power, breaker panels, etc).

Pcb reflow oven how to#
Better yet, I've released all of this as completely open-source for everyone to enjoy, including EAGLE PCB files, Arduino IDE example code, sample Android app for Bluetooth control, and full tutorials on how to modify a toaster oven to start cookin’! I have tried running a cycle of the oven with a thermocouple placed in through the draw and it seems to reflect the temperature expected in the profile, but it is possible that there is an exposed element close to the back of the oven.The Reflowduino is an all-in-one Arduino-compatible controller board that I personally designed and built, and it can easily transform a toaster oven into a PCB reflow oven! It sports a versatile ATmega32u4 microprocessor with micro USB programming interface, an integrated MAX31855 K-type thermocouple interface with noise filtering, Bluetooth Low Energy (BLE 4.0) for easy communication with a mobile device, LiPo battery charging and status indication, an optional solid-state relay, and a piezo buzzer for playing your favorite theme songs. A ground plane would at least spread the heat more evenly across the board and may stop this localised burning. The only thing I can think about the design is that I haven't put a ground plane on either side of the board in this design. Given that this has failed on 2 boards from different PCB manufacturers it must be to do with either my design or the oven. The area that fails is near the back of the oven, and part way through the heating cycle there is a bad smell and when the oven is opened I have a blistered board and oozed burnt board innards. It appears that the board is getting locally too hot in the oven. The failure mode in the oven is pretty much exactly the same. I tweaked the design a little and had the PCB remade using a different board house. After the initial failure I asked the board house whether there was any issues with the batch that I had received, but their replay was that it was 5 months since receiving them and they suspected water ingress into the board causing the failure (The black board in the image - tested bare after a failed populated board). But one of my latest designs seems to fail whilst in the oven.
I have done boards up to 100x100mm previously without any problem. Hi experts, I have made a few PCBs and used a relatively cheap Chinese reflow oven to solder the surface mount components.
