A soldering reflow hot plate based on STM32

The STM32-Based Reflow Hot Plate Project is an open-source initiative aimed at creating a reflow soldering hot plate using the STM32 microcontroller. This project provides an affordable and customizable solution for hobbyists looking to solder surface-mount components onto printed circuit boards with precision and control.

- IMS PCB heatbed capable of reaching 210°C, with uniform thermal distribution. - PID-based temperature control with ±5°C accuracy. - Redundant sensing with PT100 RTD (ADC) and K-type thermocouple (MAX6675 via SPI). - User interface with OLED (I²C), tactile buttons, and…

Reflow Hot Plate Control Board: common questions

What microcontroller does the Reflow Hot Plate Control Board use?

The Reflow Hot Plate Control Board is built around the STM32F103CBT6, from the STM32 family.

How big is the Reflow Hot Plate Control Board?

The Reflow Hot Plate Control Board measures 80 × 80 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Reflow Hot Plate Control Board?

95 components, from 50 distinct parts. The full bill of materials is listed on this page.

Where can I download the Reflow Hot Plate Control Board design files?

From the ikajdan/reflow-hot-plate repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Reflow Hot Plate Control Board design in my own project?
