A PCB design isn’t worth much if it can’t be manufactured, or if it gives your fabricator a migraine. But there has been an apparent disconnect between design and fabrication, to the point that the industry had to come up with a special term: design for manufacturing, or DFM. We focus on the ins and outs of DFM in this issue of The PCB Design Magazine.
Michael Ford of Mentor Graphics explains why Lean NPI practices can lead to a more manufacturable design. Ben Jordan of Altium helps close the gap between design and fabrication, and explains why all manufacturers are not created equally. Mark Thompson of Prototron Circuits discusses the reality of using good DFM practices every day. And Amit Bahl of Sierra Circuits focuses on why consulting with your fabricator is so critical, especially with complex or hybrid designs. You’ll also find our regular columns by Barry Olney and Dan Smith, along with a brand-new column by Tim Haag of Intercept Technology, “Tim’s Takeaways.” All this, plus industry news highlights and upcoming events, can be found in this month’s issue of The PCB Design Magazine.
Do you run simulation on your PCB designs? Circuit boards have grown increasingly faster and more complex, yet simulation is still not standard procedure, even with high-technology designs.

What is Signal Launch and Why Should You Care? by John Coonrod
What does your company do when a board fails? When the board is designed, fabricated and assembled by three different entities, not to mention shipped by a fourth, figuring out what went wrong can be difficult, not to mention time-consuming.
This month, we’re approaching this question from the point of view of the PCB designers and design engineers, because they tend to bear the brunt of the blame when a PCB starts smoking.
In our first feature, Gaudentiu Varzaru of the Politehnica University of Bucharest discusses all the ways for problems to creep into a PCB design, including overly automated EDA tools. Scott Decker of UTC Aerospace Systems explains why no one has the right to point fingers—there is plenty of blame to go around when a board fails. EPTAC’s Kelly Dack focuses on the use of root cause analysis, and how RCA can help technologists quickly find the cause of failure and make sure it never happens again. And consultant Tim Haag explains how tough it is to find the root cause. He shares a few horror stories about failures that were not his fault, despite what everyone else thought at first.
We also have columns from our columnists Barry Olney and John Coonrod. And we are introducing Jade Bridges of Electrolube, whose first column focuses on coatings for thermal management.

This month, our contributors David Wiens, Mark Thompson, Martyn Gaudion, Sharon Starr, and Abby Monaco peer into their crystal balls and discuss what we can expect in the coming year or so.
PCB designers get downright exorcised about their EDA tools. One point of contention has to do with automation itself: How much is too much? Some designers prefer manual control—not just for routing, but for much of the layout. Others want as much automation and horsepower as they can get. This month, our feature story by Intercept Technology’s Abby Monaco highlights the challenges EDA software companies face trying to give designers the power, and control, that they need. UTC’s Stephen V. Chavez explains why he prefers a mix of control and automation, and why mastery of each EDA tools is critical. Guest Editor Kelly Dack discusses why he prefers manual control for autorouting and more. And Barry Olney explains why artificial intelligence should be built into EDA tools from scratch, citing some of the repetitive tasks that could be addressed easily with AI.
We also have an interview with DownStream Technologies co-founder Joe Clark, and Joe Fjelstad’s review of last month’s TIE PCB design show in Romania.
We’ve heard it for decades: The days of throwing a design over the wall are ancient history. After all, designers have embraced fully optimized DFM processes. Right? Maybe not.
DFM continues to cause designers problems. Even designers seem to realize that they might not know all they need to know about fabrication.
In our feature interview, Consulting Technical Editor Happy Holden discusses the importance of predictive engineering in DFM, and why some PCB designers equate a design rules check with DFM guidelines. In our second feature, Happy discusses the history of predictive engineering, and how it should be utilized by PCB designers and manufacturers.
