EDI CON Online

Title: PC Board and Interconnect Design for Low EMI

Date: October 13, 2020

Time: 10:00am PT / 1:00pm ET

Presented by: Ken Wyatt, Principal Consultant, Wyatt Technical Services LLC

As a consultant for over 10 years, I’ve realized the root cause of many design issues revolves around the circuit board design and how the I/O and power connectors are arranged and filtered. Poor board designs and poor interconnect placement and filtering can result in radiated emissions, radiated immunity, and electrostatic discharge (ESD) compliance failures, among others. Bad designs often result in endless cycles of trial and error mitigation, compliance testing and board spins. This drags out the schedule and is very costly. In the presentation, I’ll explain how digital signals propagate in boards as electromagnetic fields. I’ll also explain how interconnect placement and poor filtering design and layout can affect the EMI performance. Once you understand this, then board stack-up, trace routing, filter design and interconnect placement should become very clear and you should be able to design a low-EMI board the first time!
