The difference between high voltage and high current PCB tracing?

2016/11/5 12:39:24

What is the difference between PCB traces for carrying high voltage in comparison to traces carrying high current? Would there be any difference in how they are drawn? I'd preferably have an answer that would explain the constraints and limitations in simple words of a basic level.

As far as I can see, high voltage design requires more space between copper tracks and high current design requires wider tracks.

High voltage need wider track spacing, occasional slots in the board, conformal coating or potting and use better quality materials. While high current you use wider tracks and thicker plating and more vias and sometimes additional buses.
