Description

The goal of this three-day course is to prepare electronics design and systems personnel with the necessary information to identify, design and fix EMC (and many closely related Signal Integrity) design problems.  This course addresses emissions, ESD, RFI, power, and self-compatibility.  It focuses on components, Printed Circuit Boards, power electronics, grounding, and shielding and includes over 35 practical design EMC fixes.

We consider SI a special case of EMC and while the design techniques are often the same, the levels can be vastly different. SI deals with millivolt/milliamp levels. – EMC often deals with microvolt/microamp levels. While not an in-depth class on Signal Integrity, this class covers some important basics of SI.

The class is taught by an expert in the field in a practical problem/solution format with minimal math and theory.  It is about design rather than regulations or testing, emphasizing common interference and signal problems faced by the designers of today’s high-speed digital and mixed digital/analog circuits and systems.

Course notes and the EDN guide are included.

Who Should Attend:

Electronics, mechanical and systems engineers and technicians, EMC personnel and technical managers could all benefit.  No prior EMC knowledge is needed.

What You Will Learn:

You will learn tools, tips, and techniques from a full-time practitioner (Daryl Gerke. PE), whose only business is solving and preventing EMC and related signal integrity problems. He has prevented or solved hundreds of EMI problems for clients in a wide range of industries. He has co-authored three books on EMC and over 200 technical articles.
