The December issue of The PCB Design Magazine takes a look at an organization that's been serving PCB designers for nearly 25 years: the IPC Designers Council. Though it's managed by IPC, local Designers Council chapters are largely autonomous, and lead by often-unappreciated volunteers. We talked to a variety of movers and shakers in the DC to get a handle on where the group has been, and where it's headed.

I had the opportunity to talk with our contributor Doug Brooks recently. He has been doing some research on temperature effects on PCB traces over the last few years, and I wanted to check the status of his latest thermal efforts. He discussed his work with Dr. Johannes Adam, why temperature charts based on a trace in isolation are inaccurate, and how the industry remained so wrong about PCB temperatures for so long.

If you mention thermal management in a group of PCB designers and design engineers, Mike Jouppi’s name usually pops up. Mike is an engineer and founder of the Thermal Management LLC consulting firm. He spent years updating IPC’s charts on current-carrying capacity, which had been unchanged since the 1950s. I recently caught up with Mike and asked him to give us his views on the state of thermal management, as well as the tools and standards related to thermal design.

IPC’s fall committee meetings were held in conjunction with SMTA International, as has been the case for several years now. Patty Goldman sat in on some subcommittee meetings, including one on laminates, where she met up with Ventec COO Mark Goodwin for a discussion on thermal management from a laminate supplier’s perspective.
