PCB Currents: How They Flow, How They React

PCB Currents: How They Flow, How They React

PCB Currents: How They Flow, How They React

by Douglas Brooks

In PCB Currents,renowned PCB designer Douglas Brooks teaches essentials descriptively, in plain English, with as little reliance on mathematics as possible. Building on his widely praised seminars, Brooks explains what current is, how it flows, and how it reacts. He begins by reviewing the nature of current, and then explains current flow in basic circuits, discusses sources that supply and drive current, and addresses the unique problems associated with current on PCBs. Brooks concludes by thoroughly illuminating signal integrity issues caused by current flow. He offers practical design solutions for each common type of problem, as well as for complex challenges involving very high frequency harmonics and very short wavelengths. Perfect for PCB designers at all experience levels.



  • Covers crucial electrical engineering aspects of board design that are difficult for new board designers to learn elsewhere
  • Comprehensive: from basic current definitions and electronics laws to complex signal integrity issues
  • Free Transmission Line Simulator helps engineers visualize signal behavior at the end of a transmission line
  • Written in plain English, with minimal use of complex formulas
  • By one of the field’s leading experts and most respected authors


About the Author
Douglas Brooks has a B.S./E.E. and an M.S./E.E. from Stanford University and a Ph.D. from the University of Washington. He has had forty years of experience in the electronics industry, ranging from circuit design engineer on the space program to president of his own manufacturing company. For the past twenty years he has been president of UltraCAD Design, Inc., a premier PCB Design Service Bureau in the Pacific Northwest.

Brooks has published hundreds of articles during his career. In the last twenty years, these articles have appeared in PCB Design Magazine, on Iconnect007’s websites, on Mentor Graphics’ web pages, and on UltraCAD’s web pages. In 2003, he published the book Signal Integrity Issues and Printed Circuit Board Design (Prentice Hall).

Brooks served on the faculty of San Diego State University for three years and was a visiting associate professor at the University of Washington for one year. He has given numerous seminars on Signal Integrity Issues in PCB Design over the past fifteen years all over the United States and in Moscow, Beijing and Shanghai, Taiwan, Japan, and Australia.

Brooks finally retired in 2012.
