The capacitance is determined by the amount of copper is in the trace. So length, width and the thickness. When working with low frequency signals the capacitance is not super important.
But when working with higher speed frequencies the capacitance can actually mess up the signal integrity.
## Heat generation
Heat within traces is generated by the current flowing through it. Not the wattage. A good example of the is train lines. These run on 230.000 volts on thin wires while being able to supply multiple trains. The higher the voltage the easier it is the transport a higher amount of wattage.
## Results
the power. So I grabbed an old robot with 4 stepper motors attached but I could not get them to draw more than 1.6 Amperage. So that is why the maximum in this test is 1.6 Amperage. I also had a hard time finding a way to measure the temperature of the traces because we only had a heat gun here and the laser was not the place it was actually measuring. So 0,4 mm is not measured properly.
