Reflow Micro Table is a compact Bluetooth-controlled reflow table with an 80x70 mm working area. It is built for hobbyists who assemble PCBs from time to time and do not want a bulky professional machine taking over your desk.
It runs from a 100-140 W USB PD charger, is controlled from a web browser on desktop or mobile, and closes into a compact case for storage when the job is done.
Compared with existing compact hotplates, the 80x70 mm working area is much better than typical 50x50 mm. The other difference is the UI: profile setup and process monitoring happen in a browser over Bluetooth, which is much more practical than a minimal on-device interface.
This table is meant for hobbyists who assemble PCBs from time to time. It is not as feature-rich as professional equipment, but it covers the jobs that come up most often on a home bench:
- reflow soldering with Sn42Bi58 low-temperature paste
- bottom preheating for hot-air work
- reflow soldering with Sn63Pb37 paste using the MCH-based head
- other heating tasks such as drying parts or baking paint
The MCPCB-based head (cheap, simplified) reaches up to 180°C. The MCH-based head reaches up to 250°C. Component cost is about $85 with the MCPCB heater and about $105 with the MCH heater.
This project was built to set a higher standard in this class. It also shows beginners that the technologies behind modern electronics are accessible today. Even at home, it is now possible to build complex devices that match factory-made products, and in some cases go beyond them.
The project documentation is extensive and keeps evolving. Schematics, PCB, firmware, 3D models, and build guide are all on GitHub: https://github.com/puzrin/reflow_micro.
