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 analyser, 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.

This course comprises Day 1 (PM only), Day 2 and Day 4 of a week-long programme:

At checkout, you may choose to add either or both of Day 3 and Day 5 to your enrolment.
