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.
