We’re sad to report late-breaking news that independent engineering consultant Steve Weir has died. No details are available at this time.
Steve was a power and signal integrity guru with a variety of patents to his name. A fixture of DesignCon and a constant presence on the SI-List signal integrity forum, Steve wrote over a dozen papers on power integrity.
He also had a crazy, irreverent sense of humor that you don’t find among most engineers. I first met Steve about 10 years ago at DesignCon. He introduced me to a few other EEs, with caveats such as, “John’s an SI engineer, but more importantly, the statute of limitations has run out on his unprosecuted felonies. And don’t let him near your wife. Or your son, for that matter.”
It was like that with Steve. He didn’t seem to have a pause button. The world needs more people like that.
He will be missed.
Successful signal integrity analysis depends on a fundamental concept: impedance. Without a thorough understanding of the impedance values that a signal encounters along the way, designers cannot maintain good signal quality from source to receiver.

I-Connect007 editors Andy Shaughnessy and Pete Starkey recently met with Polar Instruments Managing Director Martyn Gaudion at productronica. They discussed the success of "The Printed Circuit Designer’s Guide to…Secrets of High-Speed PCBs," the ongoing challenge of facilitating communication between designers and fabricators, and the influence of chemical bond-enhancement processes on insertion loss.

Insulectro and Isola recently shared a combined booth during PCB West 2017. Insulectro has distributed Isola materials for years, and the companies wanted to focus on Isola’s line-up of high-speed, low-loss material sets. Insulectro’s Chris Hunrath, VP of Technology, and Norm Berry, Director of Laminates and OEM Marketing, sat down with me to discuss the challenges facing signal integrity engineers today, and some of the Isola low-loss, low-Dk materials that can help with their signal integrity requirements. You might find Chris and Norm speaking to a group of PCB designers near you.
