We dive deep into the world of open-source hardware, the role of KiCad in advancing the field, and how KiCad is paving the way for more efficient, accessible PCB design and component management.

We are so glad to have Karen Burnham as a guest for this fourth episode of Trace Talks! We started working with her this year - she hosted a few webinars and seminars for Sierra - so we thought it would be nice to welcome her in the podcast chair! In this episode, Karen talks practical approach to solving real-world EMC challenges. From identifying root causes of interference to navigating stringent standards, this discussion is packed with valuable insights for engineers of all levels. Discover the step-by-step breakdown of the EMC troubleshooting process, the importance of understanding standards as helpful guidelines rather than roadblocks, and the emerging challenges as electronic systems evolve. This conversation covers critical EMC principles and best practices that can make your engineering projects smoother and more efficient. Plus, find out how you can further your knowledge with recommended resources and join the standards committees that shape the future of the field.

In this episode of Trace Talks, we're excited to welcome Patrick Davis from Cadence Design Systems.
