Key Issues for EMI/EMC: How to Design and Build a Compliant System

If you are a design engineer, it pays to know how and why EMI testing is conducted, as well as the typical causes of failure. This course provides ways to prevent common EMI/EMC problems regarding power supplies, cables, connectors, slots, discontinuity of ground planes, and more. The focus is on EMI and RFI issues regarding PCBs as well as relevant EMI regulations in the U.S. and the European Union. Highlights include PCB radiation basics, radiation and bypass on PCBs, PCB radiation suppression techniques, grounding designs/filtering, crosstalk/termination, power and ground planes, antenna loops, spread spectrum clocking, and differential-mode and common-mode radiation.

This course covers the following topics: how the EMI/EMC tests are conducted and how to avoid many configuration layout problems; design techniques to minimize radiation/susceptibility for both digital and analog PCBs; grounding and shielding techniques; and how to overcome radiation problems with connectors, cables, and hardware slots.

This is one of five courses that comprise a week of instruction in high-speed digital design/EMI. Participants may take it on a stand-alone basis or in any combination with the other four courses:

Course Materials

Lecture notes are distributed on the day of the course. These notes are for participants only and are not for sale. Fee includes materials for each course(s) taken.

Coordinator and Lecturer

Robert Hanson, MSEE, President, Americom Seminars, Inc., Bremerton, Washington. Mr. Hanson has over 40 years of experience in the design manufacturing and test areas. His initial education was in industrial engineering (IE) and business administration. After receiving his BSEE/MSEE, he became highly involved in all aspects of electronic testing. As a digital design engineer at The Boeing Company, Rockwell, Honeywell, and Loral, Mr. Hanson designed and provided prototype operational analysis on many high-speed designs, including PCBs for AWACS, B1-B, 747-400, missiles, and ground support test equipment. He has played a very active role in automating the line, implemented robotics, participated in producibility studies, and automatic material handling. He has held positions responsible for overseeing and working in the CAE/CAD/CAT, JIT, simulation, and automatic assembly environments. He also has performed studies and headed research projects in the computer-integrated manufacturing environment. Mr. Hanson has extensive experience in the testing disciplines (both factory and field, commercial and military) and has been the testability overseer for Boeing Commercial Airline products.
