How to determine the track width and the thickness of copper plating?

Time:2018-11-19 19:39:53 Click:

Generally speaking, if the current is 25A, layers of the board and current channels of each layer can be provided, this two factors contribute to the track width and the thickness of copper plating.


That’s to say, we should not only consider the track width and the thickness of copper, but also the size and quantity of via.


For instance,

If the thickness of copper is 1 oz, the current is 1A, then the corresponding track width should be 40mm; While the current turns to 2A, the track width should be 80mm, etc.
