Printed Circuit Boards

When two circuits are in the vicinity of one another, a signal propagating in one circuit can induce a signal in another circuit, due to capacitive (electric field) and/or inductive (magnetic field) coupling between the circuits. This phenomenon is referred to as crosstalk.

It is very common for people doing simulations to make a measurement of a similar set up to validate the simulation. This is a reasonable precaution since modern simulation tools will give a very accurate answer to whatever question it is asked.

Discover the eye diagram, a very useful visual tool to analyze the quality of your connections in digital and high frequency applications.

There are several scenarios where integrated circuits (ICs) are mounted on printed circuit boards (PCBs) which might be charged-up and experience CDM-like events.

The International Electrotechnical Commission (IEC) has released IEC 61249-2-43:2016. This standard describes "Materials for printed...

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.

The paper discusses the importance of understanding the current distribution below a printed circuit board trace.

Interference between circuits is a common occurrence, which is increasingly problematic with our ever condensing technology operating in a wide range of operating frequencies. This interference, known as crosstalk, can be conducted or radiated, and we refer to the circuits generating and receiving this interference as either the source or receptor.

Introduction There are many different opinions about the best decoupling capacitor strategy for printed circuit...

Let’s do a comparison of EMI (electromagnetic interference) design and signal integrity. EMI focuses...
