Brooks D., Adam J. PCB Design Guide to Via and Trace Currents and Temperatures

New York: Artech House, 2021. — 293 p.Printed circuit board designers have lots of things to think about. Typically, the first is just connecting the dots. Then, how to do so on the minimum number of layers. Then, there are all the signal integrity issues to deal with. And then, finally, how do we size the few power traces there are for carrying the required current? This latter question constitutes only a very small fraction of the total job. But it can be the most mysterious, in part because there aren’t many reliable guidelines to work from. Then, many of the guidelines that exist are incomplete, contradictory, or, even worse, flat wrong. This book is intended to cover the entire topic of the relationship between PCB trace and via current/temperature relationships.
