About This Course

This educational program provides in-depth training on circuit board layout techniques essential for achieving electromagnetic compatibility (EMC). Designed for engineers and technicians working with printed circuit boards, this course bridges the gap in formal EMC training, offering practical knowledge and active participation exercises to enhance design skills from DC to several GHz.

What You'll Gain

  • Base your electromagnetic compatibility design decisions on logical engineering principles rather than trial and error
  • Understand the four noise coupling mechanisms that cause all electrical interference problems
  • Learn how to systematically diagnose and reduce board-level electrical interference problems
  • Improve your ability to design or manufacture electronic equipment, printed circuit boards, and metal enclosures
  • Learn to select appropriate connectors, cables, and heat sinks for integrated circuit packages
  • Design filters to effectively reduce conducted emissions
  • Gain techniques for diagnosing electromagnetic interference problems directly at the board level

Key Learning Outcomes

  • Explain why wiring inductance is more important than resistance
  • Describe how current loop area is related to self-inductance
  • Explain how resonances worsen circuit board emission and immunity
  • Determine which nets should be terminated as transmission lines
  • Describe the four noise-coupling mechanisms and two ways to reduce each
  • Explain the two reasons for grounding and the difference between a grounding conductor and a signal return conductor
  • Explain why a signal should be grounded to an external metal enclosure
  • Explain when to use series blocking and shunt diverting filter techniques
  • Understand the problem with mutual inductance between the input and output loops of shunt capacitors
  • Recognize trace layouts that have excessive inductance
  • Design more effective DC power-distribution buses
  • Understand the advantages of alternative layer stack-up configurations
