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.
Tips & Tricks: Rule-Based PCB Layout
You’ll need to refer to your fab house, both to ensure that they can build what you need, and to get the final say on their design rules. Some fab houses even have downloadable design rules for various CAD packages. That makes setting things up a lot easier.
Mentor White Paper: Characteristic vs. Instantaneous Impedance
Successful signal integrity analysis depends on a fundamental concept: impedance. Without a thorough understanding of the impedance values that a signal encounters along the way, designers cannot maintain good signal quality from source to receiver.
The Impact of HDI on PCB Power Distribution
A key aspect of HDI technology is the use of microvias. For reference, the IPC HDI Design Committee has identified microvias as any hole equal to or less than 150 microns. Multiple types of HDI stack-ups associated with blind and buried microvias can be used to meet the density and cost requirements for today’s products. Design teams should develop stack-ups in conjunction with the fabricator to minimize cost and meet signal integrity requirements.
Heat Transfer and Thermal Conductivity: The Facts
In my first two columns, I presented a broad introduction to the subject of thermal management of electronic circuits. This month I’m taking a closer look at thermal interface materials—how they can be applied to achieve efficient heat transfer, and the significance of bulk thermal conductivity in relation to heat transfer and thermal resistance.
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.
Lee Ritchey On the Future of PCB Design
I spoke with long-time PCB design instructor and Right the First Time author Lee Ritchey during the recent AltiumLive event in Germany.

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.

Lightning Speed Laminates: The Blending of High-Speed Digital and High-Frequency RF
When the terms high-speed and high-frequency are mentioned, people think they describe the same issue. But in reality, they can be two very different matters. The term high-speed generally refers to digital technology which transfers data at very high rates. But the term high-frequency is typically related to radio frequency (RF), which involves analog signals moving energy at high frequencies.
Mentor Graphics’ PADS Platform Bridges Design and Manufacturing
At PCB West, Barry Matties spoke with Paul Musto about Mentor’s PADS environment and their introduction of scalable software tools to help design better boards, from the enterprise level down to the entry level and hobbyists. They also discussed the evolution of the design process infrastructure in North America vs. Asia, and what design engineers should focus on to increase their value.
The Shaughnessy Report: Leadership vs. Management
Is your manager one of the great ones, a true leader? 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.

Beyond Design: How to Handle the Dreaded Danglers, Part 2
In Part 1, I deliberated on how dangling via stubs distort signals passing through an interconnect and also decrease the usable bandwidth of the signal. This is due to the via stub acting as a transmission line antenna, which has a resonant frequency determined by the quarter wavelength of the structure. The conventional solution to this problem is to back-drill (or control depth drill) the vias to bore out the via stub barrels, so that the via stubs are reduced in length if not completely removed. This month I will look into all the possible solutions.
Flexdude Abides: PCB Design for Satellites
Tom Woznicki, aka “Flexdude,” has focused primarily on flex circuit design since he founded Flex Circuit Design Co. in the 1990s, and he designed flex circuits for the Mars rover. But recently, Tom designed rigid PCBs for the TESS satellite. I asked Tom to discuss his work with TESS, and what it’s like switching between flexible and rigid PCBs.
John Cardone on Designing Flex for Spacecraft
If you watched footage of the Mars rover driving all over the red planet, you’re familiar with some of John Cardone’s handiwork. He’s been designing rigid, flex, and rigid-flex circuitry for spacecraft since he joined JPL in the early ‘80s, and he’s worked on some of the more ground-breaking flex circuits along the way. Now John runs his own design service bureau, JMC Design Services, and he continues to design circuitry for things that blast off. I caught up with John recently and asked him to give us the straight scoop on designing boards for spacecraft.
Mike Creeden: Care and Training of Your Designers
The I-Connect007 team recently visited San Diego PCB Inc. and received a warm welcome from CEO Mike Creeden and his youthful-looking (relatively speaking) team of designers.

Instead, he provides an account of a customer’s problem—no company names mentioned, of course—that brought into question the adhesion performance of a coating that they had been using successfully for some time.
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.
Increasing Heat Dissipation in FPGAs
In recent years, the miniaturization and modularization of electronic products have led to the increased density of electronic components and the decrease of areas for effective heat dissipation. As a result, the thermal design of high-powered electronic components has become a major focus for electronics engineers. An effective solution for FPGA heat dissipation is critical. Thermal design of the PCB aims to decrease the temperature of both components and the board through suitable measures, so that the system is capable of working at a suitable temperature.
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.

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.

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."
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.
The Roles of the Designer and the Design Engineer
Steve Hageman has been designing electronics since elementary school. An engineer by trade, he has decades of experience performing PCB design and layout.

What’s New at Zuken?
Zuken has developed some innovative PCB design tools in the past few years, and I wanted to find out more about the company’s new and upcoming technologies. I caught up with Bob Potock, vice president of marketing for the Americas for Zuken USA, and asked him what was new at Zuken.
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.
IPC APEX EXPO: Hofer Discusses the Pros and Cons of Backdrilling
General Manager James Hofer of Accurate Circuit Engineering discusses the process of backdrilling vias, including the benefits and drawbacks. Backdrilling can improve signal integrity, but it can also create stubs that may act as unwanted antennas.

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.
The Shaughnessy Report: Doing My Part for Medical Electronics
One interesting aspect of having hernia surgery recently was the number of PCBs in the operating room. I’ve never seen so many electronic devices together in my life. I saw one Agilent monitor, and a bunch of others with names I couldn’t make out. It reminded me of the IT room in most companies. I guess they had to be set up to handle routine surgery like mine, and the not-so-routine operations as well. Medical electronics is doing fine, no doubt.
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.
Systematic Estimation of Worst-Case PDN Noise: Target Impedance and Rogue Waves
In the dark ages of power distribution design, the typical advice was to use a bulk capacitor and one 0.1uF bypass capacitor for every power pin on the digital circuit. This was very unscientific, but served the industry reasonably well in low-density and low-speed circuits. As the designs got more demanding, the target impedance concept was developed. Using a target impedance, designers had a metric and a design goal to guarantee that the voltage transients stay within specified limits.
Lightning Speed Laminates: Why Do Different Test Methods Yield Different Electrical Values?
A variety of different test methods may be used for any one electrical concern. This article will discuss the issues related to determining the dielectric constant (Dk) and dissipation factor (Df or Tan-Delta). On a data sheet, a designer may see a Dk value for a material to be 3.5, as an example. Once the designer buys the material and performs necessary evaluations, it may be found that the Dk of the material is 3.8. In some applications this difference in Dk is probably not meaningful; however, for many RF and high-speed digital applications, this difference could be very significant.
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.
Beyond Design: Plane Crazy, Part 1
A high-speed digital power distribution network (PDN) must provide a low inductance, low impedance path between all ICs on the PCB that need to communicate. In order to reduce the inductance, we must also minimize the loop area enclosed by the current flow. Obviously, the most practical way to achieve this is to use power and ground planes in a multilayer stackup. In this two-part column, I will look at the alternatives to planes, why planes are used for high-speed design, and the best combination for your application.
Why Autorouters Don’t Work: The Mindset!
Ask any group of PCB designers what they think of autorouters and the majority will say that they do not use them because they do not work. I have been battling this mindset for over 20 years now and it still persists today, even with the dramatic advances in routing technology. This way of thinking generally comes from those designers who use the entry-level tools. But even the most primitive autorouter may have some useful features. It’s all about changing that mindset of the designer and having a crack at it.
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.

Polar Instruments Fine-Tunes Layer Stackup Management
Polar Instruments CEO Martyn Gaudion and Technical Editor Pete Starkey discuss Polar’s efforts to simplify specification issues related to the supply chain. Designing PCBs with mixed materials makes layer stackup management more difficult than ever, but Gaudion explains how Polar works closely with materials providers and CAD tool vendors in order to provide users with constantly updated information.
Accelerating the PCB Design Cycle
An area of communications that is often underappreciated, but has become vitally important to design efficiency, is the dialogue with the PCB fabricator. It’s critical to engage the fabricator very early in the design process to nail down the proper materials and stack-up. With so many options for via structures, it is critical to select the most appropriate structure for the design. Adding blind and/or buried vias as an afterthought can limit their utilization and drive up the printed circuit board cost.
Flex Circuit Shielding Design Options
Shielding may not be your company’s number one design concern when thinking about your interconnect designs. But if you have to shield circuits for EMI, then you will need to depend on your supplier to assist you with their favorite shielding technique and experience.
The Shaughnessy Report: Squeezing Seconds Out of the Design Cycle
When you’re designing a board, time is always your enemy. That’s what we learned when we surveyed our readers recently. PCB designers said that time pressure was one of their least favorite parts of the job, and in some cases, they were ready to retire just to avoid design cycle challenges. I imagine that many of you near retirement, and that’s quite a few of you, feel the same way.
Top Gear: PADS Professional Road Test
In this column, Barry Olney test drives the newest version of the Mentor Graphics PADS Professional EDA tool. "Based on Xpedition technology, PADS Professional is a major improvement over the previous PADS suite of tools. utilizes xDX Designer as the front-end design entry tool. The latest routing technology is fast, smooth to drive, and hugs the corners well, with all the horsepower you need for the most demanding design."
Automotive Systems Design: a Support Engineer’s Perspective
In a nutshell, the promise of the system design approach is to allow for hitting the “sweet spot” in terms of functionality, quality and reliability, in the shortest possible design time and with the lowest possible resource investments. In an industry that has a very long time to market (on average around 1,000 days), steadily increasing quality demands and an ever intensifying pressure to lower costs, all these promises become most attractive and compelling.
Mentor Graphics Helps Bridge Gap Between PCB and RF
Recently, Publisher Barry Matties met with Per Viklund, the director of IC packaging and RF product lines at Mentor Graphics, and Alex Caravajal, business development manager with Mentor.

Beyond Design: Stackup Planning, Part 3
Following on from the first Stackup Planning columns, this month’s Part 3 will look at higher layer-count stackups. The four- and six-layer configurations are not the best choice for high-speed design. In particular, each signal layer should be adjacent to, and closely coupled to, an uninterrupted reference plane, which creates a clear return path and eliminates broadside crosstalk. As the layer count increases, these rules become easier to implement but decisions regarding return current paths become more challenging.
Nick Barbin: From Designer to EMS Company Owner
Many PCB designers would rather do just about anything than pore over a P&L spreadsheet. But Nick Barbin isn’t a typical designer. He co-founded the design bureau Optimum Design Associates over two decades ago, and the company later expanded into contract manufacturing and Lean processes. In this interview, Nick discussed how he wound up leading an EMS company on the Inc. 5000 list.
Material Witness: The Use of Fillers in Composites

Panasonic Meeting Market Needs with Higher-Performance Megtron 7
I-Connect Technical Editor Pete Starkey sat down with Panasonic’s Tony Senese and Tomoyuki Abe at IPC APEX EXPO 2015 in San Diego--and high-speed digital materials, particularly those with very low-loss characteristics, was the focus of their discussion. Also noted were the positive responses from chemical process suppliers, and the realistic length of a product development cycle.
Effective Characteristic Impedance
Reflections can occur anytime there is an impedance mismatch on the line. Sources of mismatches are plentiful and include trace width changes, vias, stubs, reference plane changes, and even the so-called fiber weave effect. In this case, a trace can encounter a different dielectric constant depending on whether it is routed over glass or the epoxy resin in the dielectric material. In this investigation by Kirk Fabbri, it is the capacitive contribution of the different components that are of interest, and how they affect the characteristic impedance the driver sees.
Altium Talks 3D Flex Packaging Design
Altium Product Manager Ben Jordan and Editor Kelly Dack sat down at IPC APEX EXPO to discuss Altium’s new tools for designing flex and rigid-flex circuits. The new software allows users to model the design in 3D, eliminating the need for rigid-flex designers to create “paper dolls” for each design.
