Abstract:  Engineering Aspects of PCB Level EMC Design

    • Engineering Aspects of PCB Level EMC Design

      The PCB design is a complex cooperation between electrical, mechanical, thermal, SI,
      PI and EMC design. In a practical design, the EMC design engineer has to make trade-offs and understand the relative impact of different design choices. The lecture is an overview of the typical PCB design aspects and their role for the EMC performance. Among the aspects discussed are placement, stack-up, routing, decoupling, and grounding aspects. The design of the I/O ports , in order to pass the emissions and immunity tests is also discussed in greater detail.

      1. Introduction - what matters for EMI
      2. Stack-up principles and practical examples
      3. Placement - potential EMI impact
      4. Routing aspects which may impact EMI
      5. Decoupling: power engineering, SI and EMI approaches.
      6. Grounding scheme and exceptions, heatsink grounding
      7. Stitching
      8. Spread spectrum use and limits
      9. Ethernet port
      10. USB port
      11. Serial port
      12. Serial buses (PCIe, SAS/SATA, IB) and EMI impact

Dr. Sergiu Radu is currently Principal Engineer at Sun Microsystems, leading the EMC Design group in Menlo Park, California. His role at Sun includes the development and implementation of architectural frameworks for EMC Design through design guidelines and best practices, and to provide forward looking solutions, root cause analysis of significant EMC problems, design methodologies involving software simulations and better prediction techniques. Sergiu Radu received a M.S. and a Ph.D. in Electrical Engineering (Electronics) from Technical University of Iasi, Romania, and until 1996 he was an Associate Professor at the same university, involved in Electromagnetic Compatibility teaching and research. From 1996 until 1998 he was a Visiting Scholar at the University of Missouri-Rolla, as part of the Electromagnetic Compatibility Laboratory. In 1998 he joined the EMC Engineering group at Sun Microsystems. Sergiu holds seven US patents for EMI reduction techniques in electronic systems and has published more than 50 papers in research journals, symposia, and magazines. He is a reviewer for IEEE Transactions on EMC. He is also a distinguished lecturer for the IEEE EMC Society.
