Reading time ( words)
We’re sad to report that our friend and colleague Steve Chidester succumbed to cancer today. Steve was in marketing for more than 30 years. He spent years as product marketing manager for Cadence Design Systems, and later served as VP of marketing and head of international marketing for Zuken. He returned to Cadence last year.
I first met Steve when I started covering this industry in 1999. He patiently walked me through the basics of EDA tools and pretty much gave me the lay of the land.
Steve was just a great guy. He’d always tell journalists way more than we were used to hearing from marketing people. “Yeah, we really screwed up the timing on that release, didn’t we? Why did we do that?”
We’ll miss him.

Modern electronic products are expected to offer evermore advanced functions, while the products themselves are becoming increasingly smaller. There are two key factors for the successful production of HDI PCBs: first, making the right choices at the design stage, and then carefully choosing the factory that can support the specific technical demands of the project. NCAB Group COO Chris Nutall explains.

Until the late 1980s, many PC board designers were converted technicians, mechanical designers, and artists who learned to read a schematic and mastered artwork taping. The EEs would often share their opinions, but you could listen to them or ignore them and the circuit would likely function either way. This era created some tension between designers and their EE counterparts, because they completely ignored each other’s ideas.

During 2015, I enjoyed a very productive collaboration with Dr. Johannes Adam, from Leimen, Germany. This resulted in several papers, but one in particular is relevant for this column, “Via Currents and Temperatures.” In that paper, we used a simulation tool, thermal risk management, developed by Dr. Adam, to simulate current flowing through a via and then determine the temperature of the via. Read on to find out how our results contradicted conventional wisdom.
