Reading time ( words)
I was first introduced to James Maxwell in 1967 as a college student. I had to decide whether I would take the Maxwell fields course or the switching and coding course. Being a chemical engineering major with a co-major in control theory, I had heard about the trials and tribulations of the infamous Maxwell fields course.
After a lot of consideration, I decided to take the switching and coding course, since it was more related to computer theory, while the fields course was more related to RF, power generation/distribution, and communications.
In those days, our transistors, tubes and ICs were still pretty slow, except for radio, radar, etc. At that time, signal integrity in board layout was not an issue. I was using RTL, DTL and slow TTL logic on breadboards of non-plated through-holes with tinned-copper wire and Teflon spaghetti tubing.
But after talking with students who had managed to successfully pass the fields course, I was awed by the mathematical rigors they had endured. I was astounded when these very same students found thermodynamics so difficult. Maxwell’s eqations are not easy.

I-Connect007 columnist John Watson is teaching an introductory class on PCB design at Palomar College this fall, but this is much more than a basic design class. But John has hit a slight snafu: He needs a few more students to sign up before Aug. 23, or the class will be cancelled. It’s an online class, so you don’t have to live in San Diego to attend. In this interview, John talks about the genesis for the class and its benefits.

We’re still not officially into summer yet, but Atlanta is bringing the heat, baby! It’s hit 97 degrees a few times this week, and I now have a fan aimed right at my face. At least it’s nice and humid too. I’m glad I don’t wear make-up. And it’s been a hot week in the circuit board community. This week, Eltek reported a fire at a board shop in Israel, and Flex committed to building a 145,000-square-foor facility in Jalisco, Mexico to serve the electric and autonomous vehicle segment.

Electrical engineer Marshall Massengill is the first to admit that he has a pretty sweet gig. Marshall serves as a mentor for the Zebracorns, a robotics team based at a STEM-oriented high school in North Carolina. And he’s not just a mentor: He’s also a graduate of North Carolina School of Science and Mathematics, and a former member of one of the earliest robotics teams organized by FIRST. We recently spoke with Marshall about his work with the FIRST robotics team, and what it’s like teaching PCB design to juniors and seniors in high school.
