On November 27, 2012, Keith Armstrong presented a live webinar on “Cost-effective EMC Design by Working with the Laws of Physics.”
This introduction explored how a simple nonmathematical engineering understanding of basic electromagnetic theory leads directly to EMC techniques that save time and money, improve product performance, and reduce financial risks.
Keith provided practical, real-to-life answers to relatively complex design engineering questions, such as:
• Are you spending too much time designing and fixing problems with SI, PI, and EMC?
• What are the time-to-market delays?
• How can you meet functional specifications and pass EMC emissions/immunity tests?
• How can you better decrease design and manufacturing costs?
• Are you missing out on warranty cost reductions?
Stay tuned for future webinars from Interference Technology.
