The Shaughnessy Report: Car Talk

Reading time ( words)

My girlfriend Rita doesn’t like to drive in traffic. As an Atlanta resident, this is a problem for her, because Atlanta has some of the worst traffic jams in the U.S. (I think it’s worse than Los Angeles; I’ve never sat for three hours in the same spot in LA.) So, after her last motoring miscue, she bought a new Mazda 3—the cheapest car Mazda makes—but it’s tricked out with every anti-collision feature available.

Now, it’s almost impossible for Rita to trade paint. Hit the turn signal when another car is passing, and all kinds of alarms go off. If you drift over and touch the yellow line on either side, the car starts beeping like crazy. If the car ahead of you slows down when cruise control is engaged, the car applies the brakes automatically and keeps you a certain number of car lengths behind Mr. Slowpoke. And if the reverse video doesn’t do the trick, the car starts beeping if you’re about to back out in front of a vehicle that you can’t see.

Yes, I poked fun at Rita for having all of these countermeasures beeping and pinging, but they work great. You can even turn them off, which I would do if I had to drive her car for any length of time.

Plus, the entertainment system has a great GUI; you feel like you’re sitting in your couch at home, flipping through the channels. You barely have to take your eyes off the road (or the handy speedometer in the heads up display) to find another CD on your phone’s Bluetooth, which is the point.

All of these electronic features come at a price, though: about $5,000, in this case. But we’re willing to shell out extra cash for features that will make us feel safe, or offer us greater convenience or entertainment.

Yes, the automotive electronics segment has exploded. Early cars didn’t have much in the way of electronics. Even in 1950, electronics made up only 1% of a car’s cost. (That was probably just the Philco AM radio.) But that figure is expected to hit 35% in 2020, and 50% in 2030. The global automotive electronics market is forecast to hit $314.4 billion by 2020, and that means a whole lot of PCBs.

And that’s where we come in! This issue of The PCB Design Magazine features a cover story “Automotive Systems Design: a Support Engineer’s Perspective,” written by Monica Andrei of Continental Automotive Systems. As a design support engineer, she supports 1,700 PCB designers across dozens of countries, speaking a variety of languages. In this article, Andrei explains in detail how Continental transitioned from a traditional PCB design structure to a true systems design approach.

The newest version of Altium Designer—revision 19.0—includes functionality for designing printed electronic circuits. We wanted to get the scoop on Altium’s PEC tools, so we asked Nikolay Ponomarenko, Altium’s director of product management, to give us a tour of the new functions.

With the launch of the new Flex007 section in Design007 Magazine, we asked David Wiens, product marketing manager with Mentor, a Siemens Business, to tell us about their tools’ flex and rigid-flex design capabilities. As David explains, today’s higher-end design software tools are optimized for flex design, making workarounds a thing of the past.

When considering the long-term reliability of a PCB, you must take into account any vias on your board. While an invaluable and essential part of board design, vias introduce weaknesses and affect solderability. This article will discuss vias, the potential concerns that are introduced into your board through their implementation, and how to minimize those concerns to acceptable levels.
