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?

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.
Is Captive Making a Comeback?
Andy Shaughnessy recently spoke with Altium’s Steve Chalgren, senior VP of business strategy and planning.

Explaining the QSFP-DD Data Center Interconnect Standard
According to Cisco’s report, most IP traffic either originates or terminates in data centers. Yet as massive as the flows between centers are becoming, the data managed within those same facilities is going even higher. All of this activity means that “hyperscale” is the word of the future. Roughly one-quarter of all servers installed in 2016 went to hyperscale facilities, but that number will grow to almost one-half by next year.
So Many Standards Committees, So Little Time

Learning to Be More Flexible: Case Studies on Improving FPC Design
As miniaturization requirements force manufacturers to pack more functionality into ever-smaller packages, it becomes more difficult to conform to IPC construction recommendations. Achieving robust FPCs requires frequent, iterative interaction internally among the mechanical, electrical, and PCB design teams, as well as with the fabricators and assemblers. The sooner in the design cycle you can engage the supplier and assembler, the better.
Words of Advice: Long Component and Laminate Lead Times
In a recent survey, we asked the following question: What advice do you have regarding the current supply chain issues? Here are just a few of the answers, edited slightly for clarity. One reply really sticks out: "If the end customer is large, use their power."

Barry Matties spoke with Colette about the educational programs IPC has put in place to invest in future generations, including the STEM program at this year’s IPC APEX EXPO.
CES 2019 Showstoppers, the Show Floor, and Some Neat Stuff
CES 2019 is over, and those of us who spent four to five days trying to see and hear as much as possible are in recovery mode. There were over 182,000 attendees, and 6,600 of us were media all trying to get to as much of the 2.9-million-square-feet exhibit space as possible.
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.
January 2019 Issue of Design007 Magazine Available Now
The component shortage is getting crazy. Some PCB designers are finding their favorite capacitors on 50-week and 80-week lead times, or worse. How do you design a board today when the components you need won’t be available for a year or more? In the January 2019 issue of Design007 Magazine, we asked our expert contributors to explain the current component shortage, as well as some of the workarounds that can help you get your next design out the door sooner rather than later.
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.
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.

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.
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.
PCB Carolina 2018 Draws a Crowd of Technologists
PCB Carolina 2018, the one-day tabletop show based in Raleigh, North Carolina, drew quite a crowd to the McKimmon Conference and Training Center at NC State University on November 7. Show managers Tony Cosentino, Randy Faucette, and Lance Olive (all employees of the Better Boards service bureau) said that this year’s event showed signs of growth compared to the 2017 show, which was also larger than the previous year. They estimated that about 1,000 people attended this year, and they expect another increase in attendance in 2019.
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.
Amway Sells Beauty Products—and Designs its Own PCBs
During AltiumLive in San Diego, I met Dugan M. Karnazes, an associate electrical engineer and PCB designer at Amway.

I asked Lee to explain what he plans to cover in this course, and why PCB designers and design engineers should consider attending one of the events.
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. Altium is gearing up for the San Diego event in early October and the German show in January 2019. 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.
Chuck Bauer Discusses the Future of Packaging
When we decided to cover the future of PCB packaging, we knew we would have to interview Charles Bauer, Ph.D., owner of TechLead Corporation.

Andy Shaughnessy recently interviewed Dan Fernsebner, product marketing group director and a veteran EDA guy, and Bryan LaPointe, lead product engineer and representative of the younger generation. They discussed the next generation of PCB designers, some of the best ways to draw smart young people into this industry, and why the PCB designers of the future may need to have a college degree just to get an interview.
Help Wanted: PCB Design Layout Specialist
I was told recently that the designer, aka the PCB layout specialist, is a dying breed soon to be extinct. I wish to reassure my fellow designers that, in my opinion, you are in the catbird seat. You are in hot demand and you should have great opportunities for the remainder of your career. By the way, after reading this article, you may feel empowered to go ask for a raise. Please don’t tell your manager that I sent you!
Multi-board Design with Altium’s Ben Jordan
Not too long ago, historically speaking, most electronic products contained only one PCB. But multi-board designs have become almost ubiquitous over the past decade, and EDA software companies are working to improve and simplify the multi-board design process. Editors Andy Shaughnessy and Stephen Las Marias spoke with Ben Jordan, director of product and persona marketing for Altium, about the company’s multi-board design tools, the challenges that customers face, and the numerous trade-offs that designers must contend with while performing multi-board design.
3D Convergence of Multiboard PCB and IC Packaging Design
A new generation of 3D multiboard product-level design tools offer major improvements by managing multiboard placement in both 2D and 3D, and enabling co-design of the chip, package and board in a single environment. Multiboard design makes it possible to create and validate a design with any combination of system-on-chips (SOCs), packages, and PCBs as a complete system.
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

Excerpt: The Printed Circuit Designer’s Guide to…Flex and Rigid-Flex Fundamentals
The design process is arguably the most important part of the flex circuit procurement process. The decisions made in the design process will have a lasting impact, for better or worse, throughout the manufacturing cycle. In advance of providing important details about the actual construction of the flex circuit, it is of value to provide some sort of understanding of the expected use environment for the finished product.
Field Trip: CID Class Sees How Flex is Made at Streamline Circuits
While I was teaching my CID class for EPTAC in Santa Clara, I learned that we were only a block away from Streamline Circuits. Streamline does a lot of military and aerospace work, as well as communications and industrial electronics. The company manufactures quite a bit of multilayer flex and rigid-flex circuits, in addition to rigid boards. This would make a great field trip for my CID class!

Judging was based on creativity, depth, technical difficulty, usability, scalability, and value to society.
Still Using 1980s Formats for Design Data Handoff?
The IPC-2581 format was created in the early 2000s with the merger of two competing formats: ODB++ and GENCAM. The new format, the brainchild of the late Dieter Bergman, languished with no adoption until 2011, when a small group of companies created the IPC-2581 Consortium with the goal of getting this open, neutral and intelligent format adopted. The consortium has been growing steadily in recent years. Its membership now includes more than 100 associate members in addition to its more than 90 corporate members.

Who Really Owns the PCB Layout? Part 2
In Part 1 of this series, Paul Taubman made the bold statement that the PCB layout is just as much a mechanical effort as it is an electrical one. In Part 2, he threads the needle, explaining why he believes that a PCB truly a mechatronic design, and why mechanical engineers may be more prepared to take on the PCB layout.
APCT’s Cartel Acquisition Adds Capacity, Technology and Certifications
APCT recently acquired Cartel Electronics and its affiliate, flex and rigid-flex maker Cirtech. During DesignCon 2018, I spoke with APCT President and CEO Steve Robinson about what this acquisition means for the San Jose-based fabricator.
A Conversation with Dorine Gurney, New President of Polar Instruments
Dorine Gurney has recently been named president of Polar Instruments. With a 30-year resume that includes management positions at Mentor Graphics, Lattice Semiconductor and Tektronix, she takes the reins as Ken Taylor heads into retirement. I recently caught up with Dorine at DesignCon 2018 in Santa Clara, California.
Fully Automated Schematic Verification
Schematic verification is a part of the hardware engineer’s responsibility just as PCB layout verification is an accepted part of the PCB designer’s responsibility. However, with today’s circuit designs becoming more and more complex, time-consuming manual schematic verification is no longer an option. Manual verification of a complex circuit introduces significant risk by not identifying schematic design errors that are, in turn, passed to the downstream processes and ultimately to the fabricated board.
What’s New in EDA: The Experts Discussion
We wanted to find out what’s new in the world of EDA. Joining us on our experts conference call were Polar Instruments Managing Director Martyn Gaudion, DownStream Technologies founder Rick Almeida, and Director of Product Management Mark Hepburn and Product Management Group Director of Allegro Enterprise Products Hemant Shah, both with Cadence Design Systems. The group discussed the challenges and opportunities they see in our industry, as well as the need to bring new blood into the PCB design community.
Thermal Management Update with Doug Brooks
I had the opportunity to talk with our contributor Doug Brooks recently. He has been doing some research on temperature effects on PCB traces over the last few years, and I wanted to check the status of his latest thermal efforts. He discussed his work with Dr. Johannes Adam, why temperature charts based on a trace in isolation are inaccurate, and how the industry remained so wrong about PCB temperatures for so long.
Mike Jouppi Discusses his Drive for Better Thermal Data
If you mention thermal management in a group of PCB designers and design engineers, Mike Jouppi’s name usually pops up. Mike is an engineer and founder of the Thermal Management LLC consulting firm. He spent years updating IPC’s charts on current-carrying capacity, which had been unchanged since the 1950s. I recently caught up with Mike and asked him to give us his views on the state of thermal management, as well as the tools and standards related to thermal design.
IEEE’s Romanian SIITME Show a Success
The 23rd annual IEEE International Symposium for Design and Technology in Electronic Packaging (SIITME) was held in Constanta, Romania, in October 2017. It attracted more than 190 participants from Romania, and 13 other counties. While there might be some who question the suitability of Romania as a venue for such a conference, the country has a long technological history and has produced some top innovators and pioneers in aviation including Aurel Vlaicu, Traian Vuia, Henri Coanda, who prototyped an early jet aircraft in 1910.
HDI PCBs: Make the Right Choice from Design to Volume
Modern electronic products are expected to offer evermore advanced functions, while the products themselves are becoming increasingly smaller. There are two key factors for the successful production of HDI PCBs: first, making the right choices at the design stage, and then carefully choosing the factory that can support the specific technical demands of the project. NCAB Group COO Chris Nutall explains.
Three Perspectives for HDI Design and Manufacturing Success
Mike Creeden has been in the PCB design industry for more than 40 years now. In June 2003, he founded San Diego PCB Inc., a design bureau serving a variety of industries, including industrial, automotive electronics, medical diagnostics, internet of things (IoT), defense, aerospace, and communications markets. So, we asked Creeden to share his insights about HDI, and how designers and manufacturers can address those issues.
Who Really Owns the PCB Layout?
In order to understand the current climate, we have to look at the division of labor that took place in electronic design about 40 years ago. The labor was divided into two processes, with the first being the design itself. This process was (and still is) owned by the electrical engineers. Though circuit design has changed, the methods for representing the circuit have not. Paul Taubman of Nine Dot Connects explains.
Cannonballs, eBooks, and Signal Integrity
I-Connect007 editors Andy Shaughnessy and Pete Starkey recently met with Polar Instruments Managing Director Martyn Gaudion at productronica. They discussed the success of "The Printed Circuit Designer’s Guide to…Secrets of High-Speed PCBs," the ongoing challenge of facilitating communication between designers and fabricators, and the influence of chemical bond-enhancement processes on insertion loss.

In this half of the interview, we discuss the potential for artificial intelligence in EDA software tools, the graying of the designer pool, and what can be done to draw more young people to PCB design.
AltiumLive Summit—Munich, Germany, Part 2
Pete Starkey continues with his review of the AltiumLive PCB Design Summit held recently in Munich, Germany. The second day commenced with a new product launch. “Working together is hard” it read on the screen. Statistics indicated that 33% of new products were late getting to market, of which 28% were late due to insufficient collaboration, and up to 50% of potential revenue could be lost through being late to market. Then the screen read “NEXUS makes it easy!”
Nine Dot Connects: Good Design Instruction is a True Value-Add
Nine Dot Connects has certainly blazed an interesting trail. The company started out as an Altium reseller, but in less than a decade, Nine Dot Connects has also become a design service bureau and a provider of PCB design instruction, training, and consulting services. I recently interviewed Paul Taubman, technical services director for Nine Dot Connects. We discussed the company’s expansion from VAR to service bureau and content provider, and the changing landscape of PCB design instruction.
AltiumLive Summit—Munich, Germany, Part 1
Altium held a very successful AltiumLive PCB Design Summit in San Diego, California at the beginning of October for the benefit of their North American design community, and followed it three weeks later with a counterpart European event in Munich. And what an eye-opener it proved to be—literally hundreds of delegates, a superbly organised and managed programme, billed as a completely immersive two-day interactive design experience on a theme of learning, connecting and getting inspired.
Happy Holden and Charles Pfeil Discuss the Past and Future of PCB Design, Part 1
When it comes to the PCB design community and the challenges facing it, as well as where design has been and where it’s heading, there aren’t many people as qualified to speak on the topic as long-time industry veterans Happy Holden and Charles Pfeil. Joined by I-Connect007’s Barry Matties at the recent AltiumLive 2017 event in San Diego, the three sat down for a discussion about the current state of PCB design, what the future holds, and what it means to be a designer.
Insulectro Teams with Isola to Address Signal Integrity Needs
Insulectro and Isola recently shared a combined booth during PCB West 2017. Insulectro has distributed Isola materials for years, and the companies wanted to focus on Isola’s line-up of high-speed, low-loss material sets. Insulectro’s Chris Hunrath, VP of Technology, and Norm Berry, Director of Laminates and OEM Marketing, sat down with me to discuss the challenges facing signal integrity engineers today, and some of the Isola low-loss, low-Dk materials that can help with their signal integrity requirements. You might find Chris and Norm speaking to a group of PCB designers near you.
Carl Schattke: I Started Designing Boards When I Was 12
Growing up with a father who owned a PCB design bureau, Carl Schattke, CID+, may have been predestined to design circuit boards for a living. In fact, he’s been designing boards for nearly his entire life. Carl gave a keynote speech at the recent AltiumLive event in San Diego, where I caught up with him to discuss a lifetime spent in PCB design, as well as the graying of the PCB design community and what might be done to inspire a youth movement in PCB design.
Polar Instruments’ Martyn Gaudion Discusses Tools and Books
Polar Instruments has pretty been busy lately. In the last year, Managing Director Martyn Gaudion has written two books for I-Connect007, and the company has been working to upgrade its tools, especially library functionality. I met with Martyn at PCB West. We discussed Polar’s newest tool updates, Martyn’s new side job as an author of technical books, and the continuing growth of the EDA segment, including among young people.

Predictive Engineering: Happy Holden Discusses True DFM
Happy Holden has been involved in DFM for over 45 years, since he first started working at HP and optimized their PCB design and manufacturing processes. Naturally, for this issue, Barry Matties and Andy Shaughnessy made it a priority to get Happy’s thoughts on DFM, and what true DFM entails.
It’s Not Your Father’s DFM Anymore
What does DFM look like today? Well, for one, it’s become more than DFM. We now expect our software tools to serve us more completely to take new designs to market. DFM has evolved to become an integral part of new product introductions (NPI). Today’s NPI software spans design and manufacturing to accelerate the optimization of a PCB for manufacturing. It looks at the entire design-to-manufacturing release process and deliverables, then streamlines them.
Sensible Design: Thermal Management—The Heat is On
Thermal management materials are designed to prolong equipment life and reduce incidences of failure. They also maintain equipment performance parameters and reduce energy consumption by reducing operating temperatures, and minimising the risk of damage to surrounding components. Indirectly, they maintain brand reputation, as the reliability of the equipment will be very dependent upon the effectiveness of the thermal management technique used.
The International Paris Air Show with ASC’s Anaya Vardya
The International Paris Air show is the crème de la crème of the world’s trade shows. This is the big one, where all the aircraft, airline and defense aerospace companies meet to introduce new products, discuss the future of aviation, and make deals. This year I decided to talk to my friend Anaya Vardya, ASC’s president and CEO, about the show, why he goes and what it’s like.
Resins: Cutting Through the Technical Jargon
This month, I’m going to cut through some of the more heavy-going tech-speak, taking a few of my customers’ more frequently asked questions about resins to try to help you refine your selection process. There’s a lot of ground to cover, but for the purposes of this column, let’s concentrate on the PCB’s operating environment, caring for the components that are to be encapsulated, and the special needs of applications like LED lighting and RF systems.
New Challenges Facing Mil/Aero Segment
For this month's issue, we invited a sampling of professionals whose experience centers on the electronics industry in the military and aerospace world, including experts from design, PCB manufacturing, and the assembly arena to sit down with us for a frank discussion. Our discussion centered on the challenges associated with military work, including the new regulatory requirements for cybersecurity, dealing with leaded vs. lead-free components, and the differences and similarities with the commercial world.

Orange Co. Designers Council Meeting Focuses on Embedded Passives
On July 19, the Orange County Chapter of the IPC Designer’s Council hosted a lunch-and-learn meeting in Tustin to discuss the benefits of embedded passives. Approximately 40 people were in attendance, which was lighter turnout than usual, most likely because of summer vacations. But the crowd was an enthusiastic one, as usual. The first speaker was Bruce Mahler of Ohmega Technologies, followed by Jin Hyun-Hwang of Dupont.
Trilogy Circuits: Mil/Aero Demands Technological, Regulatory Expertise
In the 16 years since its founding, Trilogy Circuits has become one of the go-to companies for mil/aero PCB design and manufacturing. I spoke with Charlie Capers, president and founder of the Richardson, Texas firm, about how he keeps ahead of the game. As he explains, succeeding with mil/aero PCB work requires not only mastery of the technological side, but of the regulations and certifications as well.
Using Vibration and Acceleration Analysis to Improve Reliability
Deriving the physical constraints and fatigue issues for a design prior to manufacturing is essential to reducing board failure and thereby improving product quality. In harsh environments, fatigue can be responsible for up to 20% of failures. Customers have come to expect reliability across the industry spectrum no matter where actual production occurs. Reliable products have less risk of failure, less field returns and less warranty claims, all of which contribute to higher profitability. It is a given that every product is expected to fail at some point, however premature failures can be mitigated through proper design with attention to potential issues due to vibration and acceleration.
Embedded Technology: A Useful Tool in Freedom CAD’s Toolbox
Freedom CAD has been designing and fabricating boards with embedded technology for years, and doing some pretty innovative work along the way. I asked Scott McCurdy, Freedom CAD’s director of sales and marketing, to share some details about their embedded processes, as well as the challenges and opportunities that embedded technology offers.
Global Impact on European PCB Fabrication: EIPC Summer Conference 2017, Day 1
Electronics industry professionals from 13 countries, mainly from Europe and Scandinavia, others from the USA, but some from as far away as India and Japan, gathered in Meriden, the centre of England, for the EIPC Summer Conference.
Sensible Design: Casting a Spotlight on Resin Applications
Over the last few columns, I’ve given readers pointers on virtually every aspect of potting and encapsulation resins, ranging from their formulations and special properties to their applications, benefits and limitations. It’s probably high time, therefore, to take a step back from the do's and don’ts and focus instead on how these resins are bringing very real benefits to practical electronic and electrical engineering applications. A good starting point is to look at the special requirements of an industry that is enjoying explosive growth: LED lighting.
TTM Shines a Light on Optical Interconnect
Are embedded optics on PCBs set to make a breakthrough in the upcoming years? According to Dr. Craig Davidson, VP of Corporate Technology at TTM, it might be closer than you’d expect. In a recent interview with the I-Connect007 team, Craig outlines TTM’s current pursuit of high-volume manufacturing lines able to deliver embedded optical interconnect, what that would mean for the PCB industry, and why he thinks there will be manufacturing production capability by 2020.
'Flexdude' Tom Woznicki Celebrates Company’s 25th Anniversary
Twenty-five years ago, Tom “Flexdude” Woznicki got laid off. A lot of people did, back during the mini-recession that helped bring Bill Clinton into the White House. So, he launched his own flex circuit design bureau and never looked back. Since then, he’s designed flex circuitry for everything under the sun, including the Mars Rover; the flex circuits he designed are visible in many of the Rover photos. I ran into Tom at DesignCon 2017 and we discussed the benefits of flex circuits, the expansion of the flex market, and his company’s first quarter-century in operation.
Mentor Graphics Takes Best Paper Award at DesignCon
At DesignCon, I met with Dave Kohlmeier, senior product line director for Mentor Graphics. We discussed their Best Paper award and DesignCon sessions such as the Signal Integrity Boot Camp, as well as the new rigid-flex capabilities found in the HypeLynx suite.
A New Power Design Methodology for PCB Designs
Advanced PCB design is an iterative process of analysis-fix-analysis. Historically, this process is very time-consuming, requiring analysis experts and PCB designers to work together to find and fix layout problems. This article describes a new PCB design methodology that allows a PCB designer to perform the power design without having to run expert-level analysis tools. This methodology provides the setup automation for advanced analysis without the need to understand every minute parameter, and can be completed in a few steps.
