20 PCB007 MAGAZINE I AUGUST 2025 F ew engineers have moved the levers of modern electronics more decisively than Mike Mosman. From the pre-email computer rooms of the 1980s to today's hyperscale campuses cranking out AI cycles, the retired power engineer and co-founder of CCG Facilities Integration has spent four decades proving that uptime is a design discipline, not a hope. In this conversation, Mike sounds both a clarion call and an invitation: He calls the U.S. grid "horri- bly fragile," warns that heat removal now limits sili- con more than watts, and argues that data center demand is reshaping everything from GaN (Gallium Nitride) power stages to small modular reactors. Yet he also sketches an electrifying roadmap for the engineers who will bridge power, thermals, and sustainability. Whether you lay out boards, model transformers, or source wide bandgap devices, Mike reveals where innovation and opportunity will be hottest over the next decade. Barry Matties: Mike, when did you begin building data centers? My recollection is that you were building the data centers for AOL and that half the internet was running through some of your data centers. Mike Mosman: Yeah, I did a lot of the AOL data centers in Northern Virginia, an area that han- dles 70% of the world's internet traffic. That's why everybody wants to be there. As the networking in the United States and around the world is beefed up, we now see many data centers being built wherever they can find land at a reasonable cost and where the local administration is receptive. by B a r r y M a t t i es , I - C o n n e ct 0 07 Wisdom From Data Center Power Pioneer Mike Mosman S E L S P O T L I G H T
