Current IssueLearning to Speak ‘Fab’
Our expert contributors clear up many of the miscommunication problems between PCB designers and their fab and assembly stakeholders. As you will see, a little extra planning early in the design cycle can go a long way toward maintaining open lines of communication with the fab and assembly folks.
Training New Designers
Where will we find the next generation of PCB designers and design engineers? Once we locate them, how will we train and educate them? What will PCB designers of the future need to master to deal with tomorrow’s technology?
The Designer of the Future
Our expert contributors peer into their crystal balls and offer their thoughts on the designers and design engineers of tomorrow, and what their jobs will look like.

Beyond Design: Electromagnetic Fields, Part 2
In my last column, Electromagnetic Fields: Part 1, we looked at how magnetic fields revolve around the earth and how these fields are also present in a multilayer board. In Part 2, we will look at how electromagnetic fields influence transmission lines and how they can be applied in a BEM field solver.
Maxwell’s Equations describe the relationship between electric and magnetic fields. These equations describe the field strength and current density within a closed-loop environment. They require extensive knowledge of higher-order calculus, so I will not bore you (or me) with further details. However, much insight into high-speed design can be gained by understanding the behavior of transmission lines and their associated electromagnetic fields.
Editor's Note: This column originally appeared in the April 2013 issue of The PCB Design Magazine.
