Overview
7+ Hours of Video Instruction - PCB Signal Integrity LiveLessons is a complete, detailed course on signal integrity for printed circuit board designers. There is no other media (including in person seminars) that provides so much material in such an easy-to-learn, convenient format.
Description
Doug starts the course by introducing the basic electronic background information necessary for understanding the rest of the material. This includes his perspective on the historical evolution of signal integrity issues on PCBs. He then devotes the next six lessons on specific signal integrity topics, ranging from EMI and crosstalk to bypass capacitors, to the skin effect, their impact, and solutions to the problems they impose. Before concluding with some final thoughts, Doug adds a lesson on the relationship between trace currents and temperatures, and how to address very large current surges that might melt (fuse) a trace.
Skill Level
· All Levels
What You Will Learn
· The role of rise time in signal integrity issues.
· The root cause of the various signal integrity issues.
· The “problem” and impact of the various issues.
· PCB design solutions to those signal integrity issues.
· Problems to avoid in implementing the solutions.
Who Should Take This Course
· Literally, anyone who designs printed circuit boards. The problems and solutions discussed in these lessons can apply to ALL circuit boards.
· Although this material would not be required for people in related industries (e.g. board fabrication and board assembly), it would be beneficial for them to also understand these issues.
Course Requirements
· Although there are no prerequisites to this course, it would be beneficial for the student to have a basic understanding of electronic circuits and of how circuit boards are designed and fabricated.

Great presentation, thanks for putting in the hard work! I'm guessing calculating the values of termination resistances is a whole other lesson...

Great Work.. I have a question. Does forward/backward crosstalk not reflect at far-end? if not properly terminated at far-end. Just like the far-end was not terminated in "Basic concept" slide.

What software did you to simulate those electric and magnetic field on the trace?

Sir, can u upload more videos....

Would it be possible to star the software used for that simulation. I am trying to do something similar using keysight Genesys and EM pro with very limited time to learn the ins and outs of those softwares. Thank you.

At 1:41, its said that if there is no return path, current can't flow. In this video (at 7:00) kzfaq.info/get/bejne/r7mliL12z6e2gI0.html Rick Hartley states that the purpose of shielding around a signal wire purely to extend the faraday cage--connecting it to the chassis, not circuit ground. So how does a signal flow through if there is no return path, and the electric field has nothing to couple to?

Hey I am glad you asked this question.. both statement u pointed are valid.. "Rick Hartley states that the purpose of shielding around a signal wire purely to extend the faraday cage".. It is important to understand which field he is talking of.. here this means to contain the external field in microstrip to contain EM field in the air.. thats where u involve chasis and all.. this means return path still exist (kinda implicit, but I understand why u r confused).. without a return path there is no EM flow.. energy is contained in the fields the dielectric spaces.. so to even have flow of current there is a closed loop and this mandates a return path to close the loop
