The Heater is Controlled by 230 V 50 Hz Main Voltage so I have to switch way slower than 50 Hz for an better power control. This means that the SSR can only switch off when the Current is zero. While working with SSR Relays, you should know that they are often build with Triacs as switching Unit. To adjust the Output Power of the Heater I have used a Solid State Relay. However there are some important things you should know. The STM32 will handle the complete control of the Oven. Sheet of Alu-Dibond / Aluminium for the Frontpanelįor this Project, I have used a STM32F103C8T6 Microcontroller, which I have programmed with CUBEMX and STM32CubeIDE. You will need some screws to mount the display and the front panel Quantity Here are all the requierd components, for the reflow oven Quantity I have found a used one on Ebay Kleinanzeigen for 20€ in my neighborhood which fits perfectly :
#USED REFLOW OVEN PLUS#
Fixed Integral Wind-Up in PID Controller, Actual Temp will draw longer nowįor base the of the reflow oven you will need a cheap Pizza Oven, the more power, the better is oven is suited for an reflow oven, also an integrated ventilator is a plus point. If you like my Instructable, please vote for me in the Automation Contest Permanent storage of the settings (Stored in Flash).Modern GUI with Temperature Curve, Keypad and Parameters.The reflow oven has the followings features: So I started to build my own reflow oven and decided to make it Open Source :-) Sadly I couldn't find one which will look that professional I would like. However a Industrial grade Reflow Oven is really Expensive, so I have searched the Web and I saw a lot of People converting an old Pizza-Oven to a Reflow-Oven. In the Industry, the standart is an Oven with a predefined Temperature Curve, a so called Reflow-Oven. However many SMD components you can buy are so tiny that they are really hard to solder. In this Instructable I want to show you how you can build your own SMD Reflow Oven for under 60€.įor a few month now, I decided to getting deeper in electronics und PCB-Design.
