I recently interviewed Les Beller, a long-time PCB designer who is now a manufacturing engineer for DISH Technology. We discussed his company’s business shift towards 5G and streaming, and the stresses that puts on a design team. He also explains the greatest challenges that he’s facing with HDI and higher frequencies, and the added importance for designers to understand the manufacturing process and DFM tools.

Polar Instruments has hired some talented technologists recently, including a new president, Dorine Gurney. At DesignCon, I had the opportunity to sit down for an interview with Dorine and Ken Taylor, Polar’s outgoing president. We talked about Dorine’s objectives for the company and Ken’s plans for life after Polar.
For the February issue of Design007 Magazine, we interviewed Nolan Johnson of Sunstone Circuits, and Dan Beaulieu of DB Management—our regular columnist—on the topics of knowing your customers, the challenges in dealing with customers, and providing excellent customer satisfaction.
