The Future of EMC Engineering: Why FR-4 is Obsolete for Tomorrow’s Technology

A discussion topic between designers, namely those who only do circuit design and have no interest in the field of EMC, and compliance engineers attempting to meet regulatory compliance requirements, is the use of FR-4 as the core material for printed circuit board construction. Fiberglass Resin (FR) is low cost and has been used in almost every electrical product for decades, with exceptions such as military and satellite applications, harsh environmental conditions, and other unique uses. The disagreement lies with the extent that we can use FR-4 in high frequency applications and should we be concerned more with electrical performance or manufacturing and assembly.

The Future of EMC Engineering: Locating RF Energy on a Printed Circuit Board

In the last issue, we examined the definition of who we are as a profession, which is an electrical engineer and nothing else; not analog, digital, digital microwave, or microwave. Everything we work with is analog. With this said how do those who are comfortable with wave propagation (RF), and only work with spectrum analyzers, identify and solve an EMC event?

The Future of EMC Engineering: Defining Who We Are

This is the first in a series of articles that, instead of focusing on technical aspects of EMC design, engineering, testing, and standards which all of us enjoy reading, I am taking a different approach as a contributing editor to examine in a controversial manner who we are and where our career may possibly take us in the future.
