Solder heaping works best for thick traces (2mm+) where there's lots of surface area to create sufficient surface tension to create taller solder piles. Piles that can be several times thicker than the original trace thickness.
Nice video. Next time you should measure voltage drop while current flow through the track. You will then be able to see how many watt is lost in the trace. The very last experience is very nice demonstration.

This is a great topic! We see a lot of heat transfer phenomenon here. If you wanted to explore the topic further, it would be great to see this test on MCPCBs and thin FR-4 PCBs (0.4mm) to see how the "rule of thumb" changes with different substrate properties. For further experimentation, the boards could be oriented 90º to observe performance of convection, observing the heat on the back of the board, the differences between a trace with solder mask and without, and changes in rating when the PCB is in an enclosure preventing free air convection. Thanks for the video, I enjoyed it.
The title of this in English is as follows; As a result of passing a large current through the printed circuit board ... Is 1A true for a 1mm width? > > The text of this is as follows ; The current flowing through the printed circuit board is said to be 1A for a 1mm wide pattern, but I checked how it actually was. The thickness of the printed circuit board is 1.6 mm, and the thickness of the copper foil is 1 oz (35 μm). Wiring is on one side only.
