During consulting assignments, I observe that engineers sometimes struggle to achieve compliance.  This not only includes regulatory but functionality.  The more senior one is at design engineering, there is the tendency to do things in a manner that is familiar

During consulting assignments, I constantly see engineers struggle to achieve EMC compliance, either emissions or immunity.  This not only includes regulatory approval and functionality but also managing an in-house system that may not have been designed to include EMC and safety approvals.  They

We need to maximize the functionality of a product using printed circuit boards while at the same time shrink the physical size along with lower cost of development and production.  We are discovering that signal integrity is becoming a greater concern

There must be a source, path and receptor for an EMC event to occur.  If a radiated or conducted problem is observed during compliance testing, how do we quickly locate the source of undesired RF energy?  Many engineers will start

Many designers who create a printed circuit board, know little about the field of EMC.  Why should they since at the physical level, why worry, EMC is an electrical issue and not mechanical or structural.  For at least two generations,
