In a recent Design007 survey, we asked the following question: "What are your biggest design challenges?" Here are just a few of the replies, edited slightly for clarity.
Scott Decker, Collins Aerospace: Getting complete information from the electrical engineers. Well-defined constraints that are correct and thought out, not winged. And good mechanical data transfer; sometimes, it just isn’t any good.
Steve Knobel, Denel Dynamics: 20 GHz+ PCB layouts. Too many components in a very restricted space. Time to market.
Roger Hughes, Blackmagic Design: Ever increasing frequency and reduction of rise times. Using “standard” multilayer design with the reduction of package/pin pitch sizes. Ensuring maximum yield and therefore minimum cost.
