* The 0,4 mm trace was the first one I tested. I started with 15 watts and it was stable at 23.8 degrees. After that I increased the wattage to 20 watts and the trace instantly exploded and burned so I could not get temperature readings there.

* The 0,6 mm trace it held up well up to 27 watts where it started getting burn marks within a 5-10 seconds. The temperature rose to 45 degrees celsius. At 29 watts the pcb burned out at 68 degrees celsius.
* When testing the 0,8 mm trace I hit a roof with how much power I could consume with the robot. I could only get up to 30 watts and I did not manage to break the trace. The maximum I found before it started discoloring was 24 watts at 54 degrees celsius. This was measured after it was left on for 2 minutes.
* I could not get to the 1mm trace because the robot could not draw more than 30 watts. So thats why these are not filled in the table.
