Overview of the Webinar

The IR Technical Education Institute is set to conduct an online seminar dedicated to understanding the intrinsic role of GND (Ground) in EMC (Electromagnetic Compatibility) design. This practical session aims to equip industry professionals with essential EMC design methodologies that can be implemented right from the early stages of product development.

As electronic devices continue to evolve towards higher performance and density, addressing EMC becomes a crucial requirement during product development. Many engineers have encountered terms like 'strengthening GND' or 'GND fluctuation'; however, opportunities to systematically comprehend these concepts and reflect them in design are limited. Consequently, reliance on intuition or experience often leads to the performance of EMC strategies that fail to address challenges at the design stage, resulting in increased revisions during prototype and evaluation phases.

Content of the Seminar

This seminar will help participants grasp the essential role of GND in EMC design, focusing on the concept of return current. It will also explain the underlying meanings of common phrases such as 'GND strength' and 'GND fluctuation'. Attendees will learn about simulated EMC design strategies that target power and signal lines, optimization of bypass capacitors, and design methods for damping resistors. The training will cover practical EMC design techniques related to PCB wiring, via placement, and GND pattern design. This comprehensive approach ensures participants will be ready to incorporate EMC measures from the design phase.
