What Trace Width Do I Need for My PCB Current, Temperature Rise, and Voltage Drop Goals?

You are not the only one to look at a PCB design and realize that you may not know whether your copper traces will be able to carry the current that you are about to pour into them. One of such essential issues of PCB design that can break or make your project is getting trace width right. Too thin and you can easily overheat, or even burn the traces. Too broad and you are both wasting real estate on the board and you are also risking a rise in manufacturing costs.
