Compact USB PD-powered Reflow soldering table with BLE control via browser.

Similar projects worth following
Compact Bluetooth-controlled reflow table with an 80x70 mm working area. Built for hobby projects when you do not want a bulky professional machine taking over your desk.

Read all documentation carefully prior to ordering anything!

This table is meant for hobbyists who assemble PCBs from time to time. It may not be as feature-packed as professional gear, but it's compact and covers most hobby need.

Key points:

  • Very compact and easy to store when not in use.
  • Powered from a 100-140 W USB PD charger.
  • Controlled from a web browser (desktop and mobile).
  • 80x70 mm working area.
  • Components cost about \$85 with the simple MCPCB heater, plus about $30 for the MCH heater.
  • Simple heating profile management.
  • Up to 180°C with the simple MCPCB-based head.
  • Up to 250°C with the MCH-based head.

Use cases:

  • Reflow soldering with Sn42Bi58 (138°C) paste using the MCPCB-based head.
  • Pre-heating (130-150°C) for hot air work.
  • Reflow soldering with Sn63Pb37 (183°C) paste using the MCH-based head.
  • Other tinkering, like drying parts or baking paint.

NOTE. This project is not unique on the market, but its feature balance is tuned for enjoyable hobby use and learning. The goal is to be practical and to show that building modern electronics at home is entirely doable, even for beginners.


This project participates in the OSHWlab Stars 2026 contest. If you like it, please give it a thumbs up.


  • Github - Firmware and documentation. Read it, please, before ordering anything.
  • EasyEDA - Schematics / PCB / BOM (almost everything can be ordered in a couple of clicks).

Since the previous attempt, the world has changed significantly, and more technologies have become available. The approach was entirely changed, and the previous variant with the build log was archived for historical purposes.

  • Partially verified last updates

    I think, from this moment on, this project is okay to reproduce. I did not post details with video, here are some:

    • Assembled the new iteration of boards, new buck converter works.
    • Built-in milliohm-meter works.
      • After checking the results, I decided to use 2R heaters instead of 10R. Also ordered more MCH units to recheck.
    • Updated 3D-prints are ok

    Pending:

    • Changed hotplade oxidation type (matte instead of glossy).
    • Adjusted button hole configuration to exclude manual cleanup.
    • Still waiting for new thermal paste.
    • Still waiting for the new video lights and supports.

    In short, all critical things are verified. But there are "temporary logistic issues" in Israel due to "known reasons", and I'm waiting for my orders to verify a batch of small details. Can take up to 1 month, IMHO.

  • ​Cumulative changes after first publish

    Vitaly03/17/2026 at 02:40 0 comments

    In the last few months, after publishing, there was extensive polishing to improve the project and make it easier to build. Full log

    Web app

    • Significant UX improvement. Rework for Material Design 3.
    • Added profiles import/export to simplify sharing.

    Hardware

    • Migrated to EasyEDA Pro (better board management).
    • Completely removed RTD sensors support. TCR works pretty well and is simpler.
    • Support up to 48 volts (for future needs).
    • Magnetic lock reworked. No glue required anymore (simplified assembly).
    • Most of the mechanical parts (screws, nuts, etc.) are now from JLCMC. That significantly reduced expenses and allowed combined delivery.
    • Reworked the heater base to reduce the connectors' heating.
    • Reduced heater & whole-case height (more compact & a nice look).
    • Improved SMT stencil positioning method. Use calibrated pins instead of wire (reduced stencil drift from 0.05 mm to almost zero)
    • Improved algorithm of PD profile selection.
    • Reduced TCR measurement noise.
    • A lot of other firmware refactoring/bugfixes

    Pending for check

    The items below already exist, but are waiting for new PCBs/components to assemble and check the latest version.

    • New buck converter for 3.3V power, cheaper and easier to solder.
    • Connector for built-in milliohm meter, for MCH matching.
    • Use more robust thermal paste from 3D printers.
