Most electronics industry events focus narrowly on one technical area or a particular application or market segment. Then there’s CES. Despite its consumer emphasis, it is a tech show with a very broad scope covering a long list of applications and technologies. With its thousands of exhibits from companies large and small, this very international trade show offers a unique opportunity to learn about not only specific innovations but also the larger technical trends, which have implications for the power electronics industry… Read more»

The War On FAEs (Part 2): New Management Brings Benign Neglect

by the OT Club

In part one of this series, we recounted the heyday of the semiconductor FAEs (field applications engineers), which started in the late 60s and lasted into the 90s. During this time, companies treated their FAEs like kings, encouraging and supporting them in all their efforts to assist customers, and valuing their input on market requirements when defining new products. We also contrasted the work conditions for semiconductor FAEs during the good times with those that exist today to highlight how much the role of the FAE has changed. But how and why did the FAE role change so radically? Here in part 2 we attempt to answer that question by discussing the period when companies began to question the value of their FAEs and started cutting back on the support they were given.   Read the full story »

The subject of power integrity (PI) concerns the design, analysis and testing of components and systems for the purpose of accurate and reliable delivery of voltage and current from the voltage regulators across power distribution networks (PDNs) to complex and sensitive loads in electronic systems. The challenges of designing modern, high-speed electronic systems are making it increasingly important for engineers to understand PI.
