Advanced Printed Circuit Board Design for EMI and Signal Integrity



Overview

This course provides a unique blend of theory, applications, and numerous hardware demonstrations to describe effective PCB design strategies to eliminate EMC problems such as radiated emissions & immunity, and ESD, and to improve low and high frequency signal integrity of analog and digital sensors.
The real-time hardware demonstrations use a spectrum analyzer, oscilloscope and signal generators to illustrate inductance, common-impedance coupling, and ground loops in PCBs, cables, and systems. Specific examples of single-point, multi-point, “good”, and “bad” grounds will be discussed. We will also apply the course learning by discussing and examining actual SILENT client case histories as well as examples of integrated circuit application notes that give bad EMC design advice.

Learning outcomes

After attending this course, you will be able to:

  • Place decoupling capacitors to obtain best performance for a given layer stackup, based on the latest university research
  • Explain the pros and cons of different PCB stackups, and know where to route and not to route high frequency noise sources
  • Control trace inductance for signal integrity and low noise design
  • Correctly identify the possible noise paths that can disrupt PCB operation and choose appropriate solutions
  • Explain the problems that split ground planes cause and how to use them correctly
  • Choose & place connectors and assign signals for lowest crosstalk, best signal integrity, and lowest EMI
