Lately, more and more ECUs (Electronic Control Units) have been landing on my bench.
Nothing to worry about with EMC/EMI… at least, that’s the hope :)
Even though some of these designs are decades old, from what I can see, the layout of the outer layers shows that good EMI control strategies were applied.
Designing complex projects like this one, or the DF_ESC High-Power Motor Controller (more about it later), is never trivial.
Layout choices, partitioning and placement, return and reference strategies, and layer stack-up all play a significant role.
As they say, in professional PCB design the devil is in the details.
Mess up your stack-up design, and you can find yourself locked into multiple project respins before you successfully pass EMC testing. Not to mention the time wasted debugging where EMI problems come from, along with the headache of signal integrity issues.
The challenge is always there.
That’s why we care about understanding the source of the problem, not simply applying quick fixes.
Engineering is mostly about taking the right preventive measures and making proper considerations from the start.
Of course, this becomes far easier when you have a tested process you can rely on.
To electromagnetic enlightenment,

P.S. If you want a solid project to learn from and dive into professional PCB design, in the course link below I will walk you through the full design process and the principles behind building a professional PCB from scratch. Enroll in the course here: fresuelectronics.com/pcb-design-course
