EMI Suppression Handbook - Communiques from the Trenches

William D. Kimmel & Daryl D. Gerke

Edited by Dr. E. Thomas Chesworth, P.E. (Technical Editor, ENR)

For the past decade or so, Bill Kimmel and Daryl Gerke have been making their way in the world as independent EMC consultants. Although they do teach EMC seminars, they make the bulk of their living at a client's factory up to their elbows in a malfunctioning piece of electronics equipment. As anyone who has tried it knows, making your living this way is just a bit less rigourous than doing it by turning a spit inside a microwave oven.

For nearly as long as they've been consultants, Bill and Daryl have been recording their trials, tribulations, and war stories in ENR's "EMC Notebook." In this book we present a compilation of their communiques from the trenches. The business of retrofitting all sorts of electronic equipment to fix all sorts of EMI has given them a unique perspective on EMC. Their continued success gives us a warm fuzzy feeling that their advice is most likely useful. These stories describe a variety of EMC problems along with the fixes that resolved them. Perhaps more importantly, taken together they give an insight into a process for discovering and resolving EMI difficulties in electronic equipment.

The book concentrates on problems where, like the cavalry, an outside consultant was called in to rescue the project from failure. They are, therefore, in the main, the tough ones that stumped the usually competent in-house engineers. You will notice that certain problems recur and from that you can infer the likelihood of occurrence.

The stories are presented in the order in which they were published between 1989 and 1998, and were not rewritten to bring them up to date. Some of them include references to particular EMC specifications which may be obsolete now, so the reader should be aware that these references may have only historical significance.

Price, $25 plus shipping.

Electromagnetic Compatibility in Medical Equipment: A Guide for Designers and Installers

William D. Kimmel & Daryl D. Gerke

EMI is the most important issue in medical electronics today, with the FDA and the European Union taking proactive roles in its control. This book provides practical design and installation guidance to those concerned with the two primary issues in the design of medical electronics-regulatory considerations and the threat of litigation. The concerns with electromagnetic interference impacting patients' critical healthcare equipment cannot be overstated: you must protect yourself and others. These EMI problems can most effectively be addressed early in equipment and system design and Electromagnetic Compatibility in Medical Equipment offers you the help you need.

Electromagnetic Compatibility in Medical Equipment is vital reading for designers, installers, quality assurance professionals, and others involved with the design and operation of all classes of electronic medical devices and equipment. Equipment must be designed to prevent radiation from your device affecting others. Equipment must be designed to prevent its operation from being affected by others. Electromagnetic Compatibility in Medical Equipment shows you how to do this step by step.

From Radio Frequency Interference (RFI) to Electrostatic Discharge (ESD), passive components, microshock hazards, and cable shielding, Electromagnetic Compatibility in Medical Equipment is the first book on this subject dedicated to the specific needs of the medical device equipment industry. Extremely thorough, with hundreds of examples of concerns and solutions, this text is a breakthrough edition for medical equipment designers.

Hundreds of resource references, lists of government documents, regulations and standards, tables of scientific material properties, and tables of constants and conversion factors complement and round out the text, making it the single most authoritative treatise on the subject.

Chapters Include:

• Introduction to EMC
• EMI Standards for Medical Devices
• The Physics of Electromagnetic Interference (EMI)
• Components and Circuits
• Printed Circuit Board Design
• Grounding for EMI Control
• Power and Power Filtering
• Interconnect and Mounting
• Shielding and Shielding Materials
• Cables and Connectors
• Special EMI Problems in Medical Electronics
• System Considerations

EDN's Designer's Guide to EMC

by Daryl D. Gerke, PE, and William D. Kimmel, PE

This guide originally appeared as a supplement to EDN in 1994 and underwent a major update in 2000. It was originally printed by Cahners, but Kimmel Gerke has acquired the reprint rights and is available from us for $29.00 including S&H for domestic orders.

This is a nontraditional approach to EMI. You won't find line integrals or partial differential equations or any other involved mathematical expressions. You won't find excruciating details on EMI regulations and testing. You will find a practical nuts and bolts approach to EMI, written for the non-EMI expert. The fourteen chapters are:
