This Month in Design007 Magazine: What Did You Expect From Me, Anyway?
As engineers, we work in the middle of a (usually long) process chain. It’s sort of like working on an intellectual assembly line—we get requirements and data as input, perform our particular task, and then provide our output as requirements and data to the next person on down the line. It seems easy enough. So, why is it that so many of the requirements we’re supposed to meet and so much of the data we receive is downright bad?
This Month in Design007 Magazine: Mentor—Managing Small Problems for Profitability
At DesignCon, I met up with Todd Westerhoff, product marketing manager for highspeed design at Mentor, a Siemens Business, to discuss common design profitability issues and cost-aware PCB design. He explains how simple problems can “slip through the cracks” and cause delays, what you can do, and how first-order analysis can make simulation accessible to designers who wouldn’t simulate otherwise.
This Month in Design007 Magazine: Al Neves on Designing for Profitability
If your company is having trouble designing PCBs for profitability, where does the blame fall? Is it management’s fault for having inefficient processes, or is it the fault of the designers and design engineers for not keeping up to date with their training? During DesignCon, I asked Al Neves of Wild River Technology to weigh in on this question. As he explains, you and your manager might both be to blame for inefficiencies in the design process.

At PCB West, I spoke with two newly minted Certified Interconnect Designers: Kalen Brown of EaglePicher and Michael Steffen of Crystal Group. After passing the CID exam, they attended the IPC Designers Council Executive Board Meeting, where the more “seasoned” veterans were very happy to meet them.
Curtis Scott Opens the Blinds on PCB Design
I recently spoke with Curtis Scott, a young PCB design engineer with Current Products, a manufacturer of automated window coverings in Pensacola, Florida. I’m always excited to hear about OEMs in Pensacola; I lived there for 17 years, and it’s a great town, but you won’t find much industry other than tourism. I asked Curtis to share his thoughts on the industry and his job designing PCBs in that scenic city on the Gulf of Mexico.
Bryan LaPointe: A Great Time to Be Working With Technology
I recently interviewed Bryan LaPointe, a product engineer with Cadence Design Systems, and one of the younger people in the world of PCB design and EDA tools. I asked Bryan to discuss some of the challenges technologists are facing in PCB design and engineering, as well as some of the things that make this field so exciting right now.
What You Need to Know About a PCB Design Career
Never stop learning. Why? Because the industry never stops changing. Those that continuously stay in that state of learning are the ones who succeed. The old saying “Knowledge is power,” often attributed to Sir Francis Bacon, has never been truer. Fortunately, there is never a lack of things to learn. Don’t ever become apathetic about learning. Make a point of keeping a running list of ideas or subjects that you want to research, and then purposely set aside time in your week strictly to study and learn about these things anywhere you can.
Designing for Complex PCBs
The I-Connect007 editorial team sat down with Freedom CAD’s Scott Miller to talk about the industry’s demand for more increasingly complex PCBs, and the challenges this presents. They also discuss Freedom CAD’s in-house training programs, the company’s recent book authored by Scott, and why communication is such an important tool in a PCB designer’s toolbox.
AltiumLive Frankfurt 2019: Carl Schattke Keynote
“How many here can remember manually taped artworks?” No more than three hands were raised in an audience of over 230 at the AltiumLive 2019 European PCB Design Summit in Frankfurt, Germany, as IPC Advanced Certified Interconnect Designer Carl Schattke introduced his keynote, entitled “Making and Breaking the Rules.” Schattke had learned PCB layout as his father’s apprentice, hand-taping several hundred PCB designs in the 1970s.

Nick provides an update for the committees he’s involved with and discusses some of the challenges that he sees as more designers enter the world of flex.
Design For Excellence: Karen McConnell on Standards
During the IPC Summer Meetings, I spoke with Karen McConnell, senior staff CAD CAM engineer with Northrop Grumman Mission Systems. Karen is a veteran PCB designer as well as an IPC committee chair and mentor. She offered an update on some of the IPC committees she chairs, the need for more mentor programs in this industry, and why you can call something a ham sandwich if you define it correctly in the standard.
IPC-2581 Continues to Flourish
Because standards adoption in this industry tends to be akin to turning around a battleship, what is often seen as new has generally already been in production for 10 years or more. Often, there are outside influences and dependencies that cause this, so most of us tend to take a “wait-and-see” approach—let others shake out the issues. And even then, we only look at adoption if the mandate comes from higher-ups in the organization. It works the way we do it now, so why change?
Happy Holden Previews His AltiumLive Frankfurt Keynote
I recently sat down for an interview with Happy Holden, who is slated to give a keynote speech at this year’s AltiumLive event in Frankfurt, Germany. Happy gives a preview of his presentation, which is focused on smart factories and automation, and why artificial intelligence might improve PCB design and fabrication in the future.
John Michael Pierobon Discusses His Flex Design Class
If you’re new to flex design, you might want to check out an online course offered by All Flex, a flex fabricator. The course, Designing Flexible Circuits, was created by John Michael Pierobon.

Leo Lambert on Training the Next Generation of Technologists
I sat down for an interview with Leo Lambert, VP of technical director for EPTAC Corporation, during the IPC Summer Meetings in Raleigh, North Carolina. We discussed the company’s growth, including plans to have training centers across different regions of the country to help cut down on students’ travel times, and why training methods must constantly evolve to remain effective.
Design Rule Checks Cut Down Board Respins
PCB designs commonly undergo multiple respins as a result of inconspicuous signal integrity (SI), power integrity (PI), and electromagnetic interference (EMI) violations. At an average cost of nearly $28,000 per respin, ensuring that a given design meets its performance, time to market, and cost goals is imperative. To help eliminate complicated and difficult-to-diagnose layout violations, some PCB tool suites offer unique electrical design rule checks (DRC).
Pulsonix Is Bullish on Next-gen Designers
During a recent trip to the U.K., Barry Matties spoke with Bob Williams, the managing director of Pulsonix, about training the new generation of designers.

Bob explained how the company had made the tool more intuitive based on user input, and he discussed some of the more cutting-edge functionality not normally found in competitively priced tools.
Design for the Unknown
Our industry loves DFx, also known as the “Design Fors.” As PCB designers, we not only design for manufacturability (DFM) but we design for assembly, reliability, cost, test, and many more factors which we like to lump together as DFx. But now, I think it’s time we embrace a new DFx: Design for the Unknown, or DFU.
Design Rules Recipe: Solvability, Manufacturability, and Performance
One thing that we’ve noticed lately: Each designer seems to have his or her own way of using PCB design rules. There doesn’t seem to be much agreement about setting or using design rules. So, in this true experts panel, Mike Creeden of San Diego PCB joined Freedom CAD’s Scott McCurdy, Jay Carbone, and Rich Kluever to share their views on PCB design rules.
Wild River, eSilicon, and Samtec Team up for 112-Gbps Test Vehicle
During DesignCon, I sat down for an interview with Tim Horel from eSilicon, Al Neves of Wild River Technology, and Matt Burns from Samtec. They’ve recently teamed up to create a 112-Gbps test vehicle that may be the first of its kind of test fixture.
Mentor’s EDA Perspective on Managing Design Rules
I recently spoke with Dave Wiens, product manager, and Mike Santarini, EDA content director of corporate marketing, both of Mentor, a Siemens business, about design rules and constraints, and what their customers want regarding design rules. They explained how EDA companies like Mentor help designers constrain for performance while avoiding over-constraining and increasing the cost of the board and also being manufacturing-aware.
Altium’s Craig Arcuri on Design Rules: Past, Present, and Future
We recently spoke with Altium’s Craig Arcuri about his views on design and manufacturing rules. Craig has experience running both design and manufacturing companies, so he has a fairly circumspect view of constraints from both sides of the product realization process. Craig details some of the challenges with setting and managing hundreds of often divergent design and manufacturing rules, and how both design and manufacturing constraints need to evolve.
Technically Appropriate Material Choices are Key to Design Success
Materials are no longer a passive part of the design; they play an active role in the manufacturability, reliability, and speed of a PCB. I-Connect007’s Nolan Johnson and Mike Creeden, founder of San Diego PCB Design, discuss several key characteristics that designers should consider in their material selection process.
Words of Advice: Your Company’s Design Process
In a recent survey, we asked PCB designers to describe their company’s design process: Is it a rigid workflow they follow to the letter, or a process that allows for their individual techniques? Of course, the comments were illustrative. Only one respondent said, "We just wing it."
XPLM: Using PLM to Integrate ECAD and MCAD Data
During AltiumLive in Munich, I met with Robert Huxel, XPLM’s director of business development for EMEA and APAC. XPLM offers data integration for some of the big EDA tool companies, and their tools can integrate ECAD and MCAD data into PLM systems. I asked Robert to tell us about the requirements of today’s PLM tools, the changing world of ECAD and MCAD integration, and whether these two types of data are ever going to converge.
Youth in the Industry Putting Training to Work
At a job fair on campus at George Fox University, Nolan Johnson sat down with Jake Whipple, a computer engineering senior, to discuss the GFU engineering program. This is one of the few engineering programs in the U.S. that gives students experience designing PCBs before they enter the work force.

Nolan Johnson recently spoke with Alex Burt, a computer engineering student at George Fox University, at a well-attended college career fair on the GFU campus in Newberg, Oregon. In the interview, Alex discusses his PCB classwork, challenges of design, and how it has impacted his internship experience as he prepares to enter the workforce upon graduation in the spring semester of 2019.
PCB Design Is All in the Family With Nicole Pacino
I shared a flight with Nicole Pacino on the way to Altium Live in Munich, and she mentioned that her father was speaking at the show. I went down the list of speakers, and it turned out that her dad is Mike Creeden of San Diego PCB. In Germany, I asked Nicole to tell us about how she got into this industry, and what we could do to draw more young people into this career.
Nano Dimension Offers Update on Dragonfly 3D Printer a Year After Launch
The Nano Dimension Dragonfly 3D printer arrived in much fanfare a little over a year ago. The company has been selling them to customers around the world, many of whom are using them to print antennas, sensors, and PCBs. At AltiumLive in Munich, I asked Product Manager Robert Even to discuss what they’ve learned in the year since the Dragonfly debuted, and some potential uses for 3D printing technology.
Bert Simonovich on Modeling Copper Roughness
I met with one of our contributors, Bert Simonovich of Lamsim Enterprises, at DesignCon 2019. Bert’s paper on interconnect modeling was nominated as a Best Paper finalist, so I asked him to discuss his paper and some of the challenges that engineers and their customers are facing right now.
EMA: Cadence Moves Simulation Further Up in the Design Cycle
Cadence Design Systems recently integrated more of its Sigrity capabilities into the front end of its PCB design tools. During DesignCon, Chris Banton of EMA Design Automation spoke with me about how this drive for “model-less analysis” benefits the PCB designer who can now access signal and power integrity, DFM, and electrical rule checking functionality early in the design process and have fewer issues later.
Cherie Litson on ECAD/MCAD and Training the Next Generation
Cherie Litson, CID+, was one of the instructors at AltiumLive Munich. I asked her to discuss some of the topics she covered in her class, and what the future of PCB design will look like. How are we going to pass down all of this design knowledge to the next generation?
Todd Westerhoff Discusses His New Position and Much More
At DesignCon, I met with our old friend Todd Westerhoff, a veteran signal integrity engineer. Todd joined Mentor, a Siemens Business, since we last spoke. We discussed his new job responsibilities, his drive to get more designers and engineers to use SI tools, and the increasing value of cost-reduced design techniques versus overdesigning PCBs.
The Electronic Component Shortage Crisis: A Veteran Engineer’s Perspective
From where we stand now, at the beginning of 2019, we see lead times for some components in the short range of up to 16 weeks; medium-to-high is 32 weeks, and long lead times are as far out as 80 weeks. In other words, if we ordered a component today, it would arrive in over a year a half from now (maybe). This all started with the capacitors (we will see why later), but we now see other component series being sucked into this problem.
Joe Clark Discusses DownStream’s Updated Tool Lineup and IPC-2581
DownStream Technologies recently revamped their entire product line, from CAM350 through BluePrint-PCB. DownStream co-founder Joseph Clark and Guest Editor Kelly Dack discuss some of these updates, including a new GUI and capabilities such as 3D analysis, as well as news about IPC-2581.

AltiumLive Munich: Day 2 Keynotes
Having enjoyed the conference dinner and robot battles of the previous evening, a good night’s sleep, and a hearty breakfast, Altium’s family of over 220 electronics engineers and designers eagerly returned to the conference room. Many jostled to secure the best seats for the second day of the European AltiumLive design summit in Munich, keen to make the most of the “learn, connect, and get inspired” opportunity it offered.
AltiumLive Munich Draws Designers from Around Europe
I’m finally unpacked after last week’s AltiumLive PCB design summit in Munich. Much like the AltiumLive event I attended in San Diego last October, the conference drew hundreds of PCB designers. This marked the second AltiumLive PCB design summit held in Munich, and Altium seems to have it down to a science. I spoke with designers from Germany, Austria, the Netherlands, and Belgium, just to name a few countries. Many of them were involved in the automotive segment but some were in medical and industrial controls as well. It’s great to be at an event that is full of PCB designers, because designers are few and far between at most PCB industry events.
The Quest for Perfect Design Data Packages
There’s an ongoing problem in the PCB industry: fabrication shops are receiving incomplete or inadequate design data packages, leaving manufacturers scrambling to fill in the blanks. For a quick-turn prototype shop like Washington-based Prototron, with over 5,000 customers and up to 60% of orders coming from new customers each month, that can add up to a lot of wasted time and effort just in the quoting stage. Dave Ryder, Prototron president, and Mark Thompson, engineering support, delve into this continuing issue and more.
Altium Prepares for Munich Show as Growth Continues
It’s been just two months since the AltiumLive event drew several hundred designers to San Diego, California, and Altium is already gearing up for the next show in Munich, Germany (January 15–17, 2019). I recently spoke with Chris Donato, VP of global sales for Altium, about the upcoming AltiumLive show as well as the company’s growth over the past few years.
A Fractal Conversation with Jim Howard and Greg Lucas
Veteran PCB technologists Jim Howard and Greg Lucas have made an interesting discovery: Certain shapes of copper planes make a PCB run more efficiently than other shapes, a process they dubbed fractal design. It doesn’t appear to cost a penny more, and testing suggests that fractal design techniques could eliminate edge noise. Barry Matties and Andy Shaughnessy asked Jim and Greg to discuss the fractal design process, and the advantages of using this technique.
Rainer Beerhalter Discusses His AltiumLive Munich Presentation
Rainer Beerhalter is a physicist, and according to his design bureau’s website, “founder, owner, and mastermind” of B GMBH. Rainer attended the first AltiumLive in Munich in 2017, and he’s returning to this year’s event in Munich January 15–17. I asked him to tell us about the class he’ll be teaching in Munich, and why he decided to come back for the sophomore AltiumLive show.
Birds of a Feather: PCB Carolina and the RTP Designers Council
At PCB Carolina 2018, I met with show founders Tony Cosentino, Randy Faucette, and Lance Olive, who are all employees at the Better Boards service bureau in nearby Cary. I asked the trio to discuss the show’s history, its relationship to the Research Triangle Park (RTP) North Carolina Chapter of the IPC Designers Council, as well as the show’s tremendous growth over the past few years.
Dan Beeker on His AltiumLive Munich Keynote and Battle With the Status Quo
Dan Beeker, senior principal engineer with NXP Semiconductors, was one of the speakers at the first AltiumLive event in San Diego in 2017. Now, he returns to AltiumLive 2019 in Munich from January 15–17 with a keynote titled, “It’s All About the Space.” Here, he discusses his keynote, which focuses on the need for designers to understand the behavior of electromagnetic fields, and why the status quo for advanced PCB design must change from, “We are going to fail,” to, “We are going to pass.”
Susy Webb: The History and Future of the Designers Council
When we started planning this issue on the IPC Designers Council, I knew I’d have to speak with design instructor Susy Webb, a longtime DC member and currently an executive board officer. I asked Susy to discuss how she first got involved with the DC, why designers should join their local chapter, and what the future holds for this group.
Dock Brown on Succeeding at Failure Analysis
Dock Brown of DfR Solutions gave a keynote speech at SMTAI, “Requirements for Both Cleaning and Coating to Building Medical Hardware.” Barry Matties and Happy Holden sat down with Dock to discuss the current trends he sees in failure analysis, the concept of “rules versus tools,” and how predictive engineering software used early in the design cycle can help predict failures in components and microvias and drive cost down.
The Readers Speak: The Design Data Format Survey
If you’re or designer or a design engineer, the odds are good that you have a few things to say regarding design data formats. We want to hear from you! Your participation in this design data survey would be much appreciated. We know that your time is valuable, and you’re getting ready for the holidays, so we’ve kept it short and sweet.
Mentor Discusses New DFT, DFM, and Design Verification Tools
At electronica 2018, John McMillan, digital marketing program manager-Electronic Board Systems, and Mark Laing, business development manager-Valor Division of Mentor, a Siemens business, discuss new tools for PCB design verification, as well as design for manufacturing (DFM) and design for testing (DFT).
Martyn Gaudion on Signal Integrity Modelling and Stackup Tools
The accuracy of signal integrity modelling continues to improve, and stackup tools are becoming widely used, which now include material suppliers' datasheet information. During the recent electronica show in Munich, Germany, Martyn Gaudion, managing director at Polar Instruments, explained how Polar often serves as a bridge between PCB design and fabrication, and why educating his customers is so critical.
New Designers Council Column: The Digital Layout
The IPC Designers Council is launching a new column in Design007 Magazine: “The Digital Layout.” I recently asked two IPC Designers Council (DC) Executive Board members, Mike Creeden and Stephen Chavez, to discuss the content and objective of their new column, and how this all ties in with the DC.
Design Data: File Naming Conventions
Working for an EMS provider, I am often asked to make sense of customers’ PCB design data packages that must be audited for completeness and manufacturability. Quite often, EMS operations receive data to produce a PCB design and begin the auditing process, only to be called off due to customer changes. Sometimes the data is incomplete, or it is missing one or more of the data files required to fabricate the PCB at the supplier. There are also occasions where a customer has sent files that were supposed to be the updated version but were not changed at all.
Impact of Serpentine Routing on Multi-gigabit Signal Transmission
Serpentine is a technique to minimize skew or misalignment of differential pairs. The number of segments and intra-pair spacing of serpentining impacts the high-speed signal transmission. As the intra-pair gap is enlarged for serpentining, the characteristic impedance of the PCB trace in differential mode will rise. This leads to impedance discontinuity, signal reflection, and ultimately, attenuation. The signal attenuation is heavily dependent on the number of segments and intra-pair spacing of the serpentine.
At GreenSource, Lean and Green Starts on the Front End
GreenSource is the first new captive shop in American in decades, and one of the first waste-free board shops as well. The CAM engineers all work remotely, and they can launch a job without ever entering the facility. I spoke with JanNell Taylor and Andy Schilloff, who work at the CAM office in New York. We discussed what it’s like working for a company that plays by its own rules, and what they're doing to get ready for the day GreenSource goes commercial
Achieving Minimal Crosstalk in Multi-board Interconnect
In an electronic system, the signal transmission exists in a closed-loop form. The forward current propagates from transmitter to receiver through the signal trace. On the other hand, for a single PCB, the return current travels backward from receiver to transmitter through the ground plane closest to the signal trace. Meanwhile, for multi-board interconnect (e.g., connectivity through flex or ribbon cable), the return current travels back to the transmitter through the ground or return wire, preferably as close as possible to the signal wire. The path of forward current and return current forms a loop inductance.
Max Seeley’s PCB Design Career is No Fish Story
Max Seeley, senior electrical, PCB, and manufacturing engineer with 3M, was an instructor at the first AltiumLive event in 2017, and he made a return visit to this year’s event in San Diego. I asked Max why he decided to come back to AltiumLive this year and to share the story of his rather circuitous journey into PCB design, which included a turn as a custom aquarium builder. Everyone in PCB design has a different backstory.

Moving From 28 Gbps NRZ to 56 Gbps PAM-4: Is it a Free Lunch?
The usual way of signaling through PCB interconnects is a two-level pulse, an encoding of 1s and 0s or bits, named NRZ (non-return-to-zero) or PAM-2 line code type. Increasing the data rate with the NRZ code type presents some obstacles. For a 28 Gbps NRZ signal, the bit time is about 35.7 ps with the main spectral lobe below 28 GHz. For a 56 Gbps NRZ signal, the bit time is about 17. 86 ps, with the main spectral lobe below 56 GHz. One can feel the problem already: Getting PCB interconnect analysis and measurements up to 56 GHz and beyond is very challenging, to say the least.
Judy Warner: AltiumLive’s Second Year to Be Even Better Than First
Last year, Altium launched its AltiumLive event with shows in San Diego and Munich, Germany. This year, the event has expanded to include an extra day of classes.

I recent spoke with Judy Warner, director of community engagement for Altium, about what designers should expect at both shows, and how the company can build on the success of the 2017 events going into the future.
PCB Design Challenges: A Package Designer’s Perspective
The challenges faced by the PCB designers of today are significant. If we examine the breadth of designs, we find ever-increasing data rates and more high-speed signal routing that drive additional challenges meeting signal-quality requirements, including reflection signal loss and crosstalk issues. At the same time, designers are being asked to complete designs in shorter cycle times and in smaller form factors. They must come up with new and more complex routing strategies to better control impedance and crosstalk. Manual implementation is often time-consuming and prone to layout errors.
Managing the Challenges of Flex and Rigid-Flex Design
PCB designers working with flex or rigid-flex technology face many potential risks that can derail a project and cause costly design failures. As the name implies, flex and rigid-flex designs comprise a combination of rigid and flexible board technologies made up of multiple layers of flexible circuit substrates, attached internally and/or externally to one or more rigid boards. These combinations provide flexibility for the PCB designer working on dense designs that require a specific form factor. Rigid-flex allows the PCB design team to cost-efficiently apply greater functionality to a smaller volume of space, while providing the mechanical stability required by most applications.

Sensible Design: Protecting PCBs from Harsh, Challenging Environments
Think very carefully about the sort of environment your PCB is likely to encounter. It is easy to over-engineer a product so that it will survive the very worst of conditions, but worst conditions may only be fleeting or transient. Therefore, a resin solution with a lower temperature performance specification will often cope. Take temperature extremes, for example. Your application may experience occasional temperature spikes of up to 180°C, which you might feel deserves treatment with a special resin.
Paving the Way for 400Gb Ethernet and 5G

Many of your colleagues would probably answer with a pointed “No.” In our reader surveys, we ask, “What is your biggest challenge?” Every time we've posed that question, we received replies along the lines of, “Management doesn’t know what the hell they’re doing.” Some replies are too salty to print.
Space: Still the Final Frontier
If this doesn’t make you feel like a “seasoned citizen,” I don’t know what will: "Star Trek" first aired 50 years ago, on Sept. 8, 1966. No one—not even the actors—thought the show would last, and it only ran for three seasons, drawing average ratings. But Captain Kirk and company are more popular than ever on their Golden Anniversary.
The Evolution of Altium: Road to a Record-Breaking Year
Chris Donato, VP of sales for Altium Americas, sat down with Judy Warner recently to discuss what he and Altium have been doing lately, where they came from (Australia) and what the future holds for Altium. This company has evolved from flying well under the radar during the acquisition frenzy of the ‘80s, to achieving a record $100 million in sales for fiscal year 2016.
Orange Co. Designers Council Meeting Draws A Packed House
Speaker John Stine, VP of operations at Summit Interconnect’s Anaheim facility, gave a presentation on flex and rigid-flex design and fabrication. At least 75 electronics professionals listened as Stine, an expert in flex and rigid-flex technologies, discussed proper trace geometries, grounding, cover lay, adhesives, signal integrity, impedance control, book-bindings and much more in his 80-minute presentation.
Sensible Design: When Coatings Go Wrong
This month, I consider some of the more common, and often very frustrating, problems that may be encountered when coating electronic circuit boards and components. I also discuss some practical solutions. As we all know, nothing in life is straightforward.
New SI Techniques for Large System Performance Tuning
In this DesignCon paper, Donald Telian of SiGuys and Michael Steinberger and Barry Katz of SiSoft describe newly-developed techniques for equalization tuning and discontinuity reduction, offering additional design margin. Cost reductions are also achieved as new signal integrity techniques demonstrate performance parity, removing non-essential re-timers and PCBs layers.
Software Bytes: Having Fun With Impedance
About a year ago, I was assigned a new project: become an expert in impedance, more or less. I had no idea how much this research would bring out the nerd in me. Even if you don’t typically design controlled-impedance circuit boards, you probably will eventually. Read on!
Getting Signal Integrity Right by Design
As clock frequencies increase and active devices and interconnect traces shrink and are placed ever closer together, signal integrity becomes an increasing challenge. Today, SI is typically addressed late in the design process after the PCB layout has been completed by performing complex and time-consuming 3D extractions and simulations for high-speed lines. But with little attention being paid to SI during the layout process, simulation frequently identifies numerous SI problems.
Beyond Design: Mastering “Black Magic” with Howard Johnson’s Seminars
Dr. Howard Johnson, the world’s foremost authority on signal integrity, has recently released his High-Speed Digital Design (HSDD) Collection. I recently reviewed all three of the seminars in this collection, a total of 36 hours of viewing time. If you want to gain some of Dr. Johnson's enthusiasm and master the art of high-speed design, then the collection is a must-have.
Designing With Tighter Tolerances
David Ledger-Thomas is a PCB design engineer with Honeywell Aerospace. He’s spent decades designing PCBs for a variety of applications, including defense, aerospace, computers, and high-performance audio. I asked David to share some of his thoughts on designing high-tech boards with increasingly finer spaces, traces and pitch.
The State of the Electronic Design Automation Nation
We are the automation nation. We are the high-speed demons, the low-frequency artists, the mixed-signal designers that make up the electronic design automation industry. We spend most of our working lives behind software, delivered to our fingertips with the promise of making things easier, faster, better, and getting us to our deadlines ever faster.
Beyond Design: The Case for Artificial Intelligence in EDA Tools
There has been a lot of activity in the field of artificial intelligence recently, with such developments as voice recognition, unmanned autonomous vehicles and data mining to list a few. But how could AI possibly influence the PCB design process? This month, Barry Olney will take a look at the endless possibilities.
EIPC Summer Conference 2016, Day 1: Strategies to Maintain Profitability in the European PCB Industry
Resplendent in the kilt, EIPC chairman Alun Morgan welcomed a large and enthusiastic gathering of printed circuit professionals from all over Europe and as far afield as the USA, Canada and Russia, to the EIPC Summer Conference 2016 in Edinburgh, Scotland's cosmopolitan capital city.
DownStream: What a Long EDA Trip it’s Been
No doubt about it: DownStream Technologies co-founder Joe Clark is an EDA veteran, with a history that dates back to the very beginning of EDA tools through the merger madness of the late ‘90s and beyond. I sat down with Joe during IPC APEX EXPO, and asked him about some of the changes he’s seen, and the direction of DownStream as it enters its 15th year.
The Shaughnessy Report: The Designer Roundtable Roundup
Every year, I attend SMTA Atlanta, just across town. You have to love a local trade show. No airlines, no jet lag, and no hotels. It’s a small show; it would fit in a school gymnasium. But for me, the highpoint of SMTA Atlanta is the Designers Roundtable. This year the roundtable had 15 attendees, up from 12 last year. Two of the new attendees were under 35, which surprised all of us "graybeards."
Design Automation Tools, Today and in the Future
Kelly Dack has been designing PCBs for over three decades, at OEMs of all kinds. Now a PCB designer with a Washington state contract manufacturer, Kelly enjoys waxing philosophic about PCB design and design automation in general. I asked Kelly about the direction EDA tools are headed, and whether he’d like to see more control, or more automation in his PCB design tools.
Beyond Design: DDR3/4 Fly-by vs. T-topology Routing
JEDEC introduced fly-by topology in the DDR3 specification for the differential clock, address, command and control signals. The advantage of fly-by topology is that it supports higher-frequency operation, reduces the quantity and length of stubs and consequently improves signal integrity and timing on heavily loaded signals. Fly-by topology also reduces simultaneous switching noise (SSN) by deliberately causing flight-time skew.
Designers Notebook: Flexible and Rigid-Flex Circuit Design Principles, Part 6
The designer is generally under pressure to release the documentation and get the flexible circuit into production. There is, however, a great deal at risk. Setting up for medium-to-high volume manufacturing requires significant physical and monetary resources. To avoid potential heat from management, the designer must insist on prototyping the product and a thorough design review prior to release.
The Partnership: Design Engineers and PCB Designers
Randy Faucette is founder, president and director of engineering at Better Boards Inc. in Cary, North Carolina. I asked Randy to talk about some of the occasional tension between PCB designers and design engineers, and what he thinks can be done to help open the lines of communication.
SiSoft: Optimizing the State of the Art
In the 20 years since its founding, SiSoft has been at the forefront of signal integrity analysis tool development. Now, the company is leading the way with a new technology called OptimEye and tools for creating accurate IBIS-AMI models. Todd Westerhoff, VP of semiconductor relations, gives us an update on the company’s newest technologies.
Behind the Scenes: Adcom’s TLA Award-Winning Design
Adcom’s design team placed first in this year’s TLA program, taking the top spot for the category of “Computers, Blade & Servers, Memory Systems.” This board, like most PCBs today, is a complex system designed by a multi-disciplinary team of designers, striving to bring an operational product to the market on schedule.
Quiet Power: Dynamic Models for Passive Components
A year ago, my Quiet Power column described the possible large loss of capacitance in multilayer ceramic capacitors when DC bias voltage is applied. However, DC bias effect is not the only way we can lose capacitance. Temperature, aging, and the magnitude of the AC voltage across the ceramic capacitor also can change its capacitance. This column will provide all of the details.
Design Strategies for Success—and Profit
In today’s economic environment, making money on a project is getting more and more challenging. Those years when businesses like mine were practically printing money are long gone. If you are under 30 years old, you probably do not have this point of reference; it’s been one downturn after another for your entire adult life. But for us older folks, times were really good back then. So, what happened? You happened, as well as a million others like you. In other words, the market is a little cramped now and much more competitive, which dilutes our profit per project.
Beyond FR-4: High-Performance Materials for Advanced Designs, Part 1
In the past 40-plus years of PCB manufacturing, the primary material of choice has overwhelmingly been e-glass supported FR-4 resin laminates. This is due to the excellent dimensional stability and reasonably acceptable thermal performance (based on glass transition temperature [Tg] and decomposition temperature [Td]). In general, these materials exhibit impressive performance and excellent cost for a wide range of applications.
Designers Notebook: Flexible and Rigid-Flex Circuit Design Principles, Part 5
The outline profile of the flexible circuit is seldom uniform. One of the primary advantages of the flexible design is that the outline can be sculpted to fit into very oblique shapes. This month, Vern Solberg focuses on outline planning, physical reinforcement, and accommodating bends and folds in flexible and rigid-flex circuits.
Wild River: Simplifying SI so Engineers Can Focus on Design
Al Neves is founder and chief technologist of Wild River Technology, and he’s a signal integrity engineer who likes to tell it like it is. So when I bumped into Al during DesignCon, I asked him to sit down for an interview. We discussed the paper he co-wrote for DesignCon and the challenges SI engineers are facing, as well as Wild River’s efforts to take the black magic out of signal integrity.
Steinberger Talks PAM4, the Next Generation of Modulation
I recently interviewed our old friend Michael Steinberger, SiSoft’s lead architect for serial channel products. Steinberger is always a great interview; he breaks down complex signal integrity simulation technology in ways that are simple and often humorous. Steinberger sat down and discussed a paper he presented at DesignCon, and some of the challenges his customers are facing.
IPC APEX EXPO: Gary Carter on First Board Manufactured With IPC-2581B
Gary Carter, senior manager of CAD engineering for Fujitsu Network Communications, discusses the first board fabricated and assembled using IPC-2581B. This 20-layer board features 21,000 component pins and 15,000 holes, with controlled impedance on all layers. He also gave a presentation on IPC-2581B during the Design Forum.
The PDN Bandini Mountain and Other Things I Didn’t Know I Didn’t Know
Originally, Bandini Mountain referred to a mound of fertilizer built by the Bandini Fertilizer Company in California prior to the 1984 Los Angeles Olympics. When the company went bankrupt, this mound of fertilizer was left behind. Steve Weir coined this term to describe the large resonant frequency peak formed by the parallel combination of the on-die capacitance and the package lead inductance, as seen from the die looking into the PDN.
Designers Notebook: Flexible and Rigid-Flex Circuit Design Principles, Part 4
All of the design rules for the glass reinforced-portion of the board (land pattern geometry for mounting surface mount devices, solder mask and the like) are now well-established. One unique facet of fabricating the rigid-flex product is how the flexible portion of the circuit is incorporated with the rigid portion of the circuit. As a general rule for multilayer PCB design, furnish a balanced structure by building up the circuit layers in pairs (4, 6, 8 and so on).
IPC APEX EXPO: Prototron Works with Customers to Stay on Top
Prototron Circuits Operations Manager Mike Graves explains how his company's focus on customer service, including helping with PCB designs, has made Prototron "America's Board Shop." He also discusses their expansion into flex and HDI technology, and their efforts to achieve AS9100 certification.
IPC APEX EXPO: Glenn Oliver on His IPC 'Best Paper' on High-Frequency Materials
Glenn Oliver of DuPont discusses his award-winning paper, “Round Robin of High-Frequency Test Methods by IPC-D24C Task Group." Co-authors include Jonathan Weldon of DuPont, John Andresakis of Park Electrochemical, Chudy Nwachukwu of Isola, John Coonrod of Rogers Corporation, David L. Wynants of Taconic Advanced Dielectric Division, and Don DeGroot of Connected Community Networks. The paper looks at high-frequency offerings from a variety of materials providers.
Mark Thompson: It’s All About Communication
In engineering support at Prototron Circuits, Mark Thompson has seen it all. He ensures that each design is manufactured the way the designer intended, even if the CAD data is not crystal clear. During DesignCon, Barry Matties and Andy Shaughnessy talked with Thompson about why communication is paramount when designing and prototyping boards. Thompson also explained how designers can avoid making common mistakes that can set back an entire project.
DuPont, Taconic and PFC Team Up For High-Speed Flex
At DesignCon, I sat down with three flex circuit specialists: Glenn Oliver of DuPont, Tom McCarthy of Taconic, and Steve Kelly of PFC Flexible Circuits. Our discussion covered a lot of territory, most notably the findings they described in the paper they were about to present later that day at DesignCon, and the future of flex, as they see it.
Designers Notebook: Flex and Rigid-Flex Circuit Design Principles, Part 2
In this installment of "Designers Notebook," Vern Solberg discusses supplier assessment, planning of the flexible circuit outline, and various circuit routing principles. Communication between designer and fabricator is paramount, as well as an understanding of IPC-2223, which sets the specific requirements for the design of flex circuits.
Designers Notebook: Flex and Rigid-Flex Circuit Design Principles, Part 1
In his new Designers Notebook column, Verb Solberg discusses primary flex circuit structures, proper design for operating environment, and base material selection. The design guidelines for flexible circuits, although similar to those for rigid circuits, have distinctive differences that are influenced by specific applications and the intended operating use environments. Communication with your fabricator is paramount when designing flex and rigid-flex circuits.
IPC Designers Council Viewpoint: Gary Ferrari
As co-founder and longtime executive director of the Designers Council, Gary Ferrari has dedicated a big part of his career to PCB design. After decades of service, he was inducted into the IPC Hall of Fame at IPC APEX EXPO this year. I caught up with Gary and asked him to fill us in on the creation of the Designers Council, and some of the changes he’s seen in the last 24 years.
Electrical Design Challenges for Automotive PCBs
A recent article in this magazine by Monica Andrei of Continental Automotive Systems emphasized the systemic nature of an automobile and discussed the characteristics and adoption of software design tools to enable such system-level design. Recognizing that electrical challenges are part of the automotive system-level discussion, this article will present more detail on signal integrity. Future discussion is planned regarding EMI, power integrity, and thermal integrity.
McCurdy: How to Build a Successful IPC Designers Council Chapter
When Scott McCurdy made his transition from PCB fabrication to a PCB layout focus about 13 years ago, he accepted an invitation to attend our local IPC Designer’s Council. Shortly after, he was recruited to serve on the group’s steering committee. At that time, 20–25 people were regularly attending the meetings. When the chapter president moved, he asked Scott to take his place. Now, Orange County chapter meetings often draw close to 100 attendees.
IPC Designers Council: Serving PCB Designers for Almost 25 Years
You may have seen Anne Marie Mulvihill at the Design Forum during IPC APEX EXPO, rounding up speakers with a sarcastic comment or two. As PCB design program manager for IPC, Anne Marie makes the design train run on time. When I told Anne Marie that we were covering the Designers Council for this issue, she jumped at the chance to help us.
IPC Designers Council Viewpoint: Rick Hartley
Rick Hartley has been in involved in PCB design and design education for decades, so it’s no surprise that he started working with the IPC Designers Council early on. Now retired from his day job at L-3, Rick still teaches PCB design and shows no sign of slowing down. I asked him to discuss his work with the Designers Council, and what the group means to the design community.
IPC: Connecting Electronics Industries
John Mitchell, president and CEO of IPC—Association Connecting Electronics Industries, provides the basic overview of the association—its goals and basic mission, activities, and how it best serves its membership. He also provides a snapshot of how IPC promotes technology development in the industry through standardization.
EMA: Helping Technologists Manage Disparate Data
Today’s EDA tools are better than ever, but managing design data, from schematics through Gerbers, can be an unwieldly task. I recently interviewed Manny Marcano, president and CEO of EMA Design Automation. He discusses EMA’s approach to managing a variety of types of complex data, the need for seamless data processes, and the future of compliance-aware design.
Orange County IPC Designers Council Meeting Draws Record Crowd
On November 18, the Orange County Chapter of the IPC Designers Council held a “Lunch ‘n’ Learn” event at the Harvard Park Community Center in Irvine, California.
