Current density can be an interesting concept. Graphics based on current density can be fascinating. But from a practical standpoint, current density is irrelevant. It is a consequence of other things, not a determinant of them. What follows will explain why.

The ability to analyze and predict the current/temperature effects of isolated traces is helpful, but the actual temperature of a trace may be different because of uncertainties in the actual trace thickness or board material thermal conductivity coefficient. This article traces the effort to see what PCB board parameters have the most impact in determining trace temperatures, followed by a look at related PCB design considerations. Read on to learn more.
