Failure Analysis: A Road Map

Although the foundation of a failure analysis is rooted in science, there is also an art to completing one, successfully. The path from “problem discovery” to “problem solution” has many bumps and twists along the way and this article will hopefully help guide you on your journey.

Making Real Boards

The board stackup is probably the most essential piece for ensuring a successful PCB design. Modern high-speed busses require controlled-impedance traces, and whether you are using a simulation tool, a simple calculator, or the back of a napkin, you need to understand your manufacturing process to correlate your impedance calculations. This ensures that your trace widths and dielectric heights match what will actually be manufactured, and eliminates last-minute design changes.

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?
