FEATURED ARTICLES AND COLUMNS:

Let’s start with the question engineers are increasingly asking themselves: “When should I use ceramic instead of FR-4?” It’s a fair question. FR-4 has been the backbone of electronics for decades. It’s affordable, widely available, and for many applications, it works just fine. Until it doesn’t.

AI begins with advanced chips, but delivering AI at scale depends on an ecosystem of technologies that extends far beyond the semiconductor. In this interview, Andrew Bradner, senior vice president of Schneider Electric's cooling business, explains how AI is transforming data center design, why liquid cooling has become essential, and what these shifts mean for advanced packaging, power delivery, thermal management, and the broader electronics supply chain supporting next-generation AI infrastructure.
