USB PD Reflow micro table

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.

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.
