Design Challenges in Printed Circuit Boards for EMC Compliance

The trend of using high speed signals with fast rise and fall time, mixed signal design and demand of compact electronic products has increased the criticality of printed circuit boards design. Electromagnetic Compatibility (EMC) is becoming a crucial issue in design of modern military electronics systems. Improper printed circuit board designs can cause to performance degradation, failure of products and non-compliance with EMC regulations. EMC guidelines set by various standard institutions ensure the reliability and safe operation of the products in an electromagnetic environment. This paper describes various design techniques that has been considered while designing various high density and complex printed circuit boards for Indigenously developed Radar systems, that not only reduces the electromagnetic emissions but also make the products Electromagnetic Compatibility (EMC) compliance.
