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?

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.
What Does Intelligent Routing Look Like?
Many PCB design projects miss schedule commitments by 70% due to delayed routing and lack of automation. Moreover, due to late-stage design changes, schedules are not met, and the addition of those new items takes 10 times longer or more to incorporate than if changes were added from the beginning. Fortunately, over the past several years, powerful routing capabilities have been added that allow designers to address a number of specific, critical tasks.
AltiumLive Frankfurt 2019: Rick Hartley Keynote

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.
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).

The IPC High-Reliability Forum and Microvia Summit covered a broad range of topics related to reliability and provided interactive opportunities to share expert knowledge and experience in determining and understanding the causes of failure and selecting the best design rules, materials, processes, and test methods to maximise product reliability.
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.
AWE 2019: Go XR, Be Awesome
Dan Feinberg attended and covered the recent 2019 Augmented World Expo (AWE) and conference in Santa Clara, California. The event featured the latest developments and technologies in augmented (AR), mixed (MR), virtual (VR), and extended virtual reality (many just call it all XR to make it simple). Here's a wrap-up of the event.
Stitching Capacitor: Crosstalk Mitigation for Return Path Discontinuity
When the return path is broken due to the switching of reference planes with different potential, e.g., from ground to power or vice versa after layer transition on PCB, the return current might detour and propagate on a longer path, which causes a rise in loop inductance. This might lead to the sharing of a common return path by different signals that pose a high risk of interference among the signals due to higher mutual inductance. This interference results in signal crosstalk. To mitigate the crosstalk due to return path discontinuity (RPD), stitching capacitors are mounted on the PCB to serve as a bridge between the two reference planes of interest on different PCB layers.
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

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."
Smart Design Data Is Essential for Industry 4.0 Manufacturing
Almost all of the conversation regarding Industry 4.0 is centered on the manufacturing floor, which is where the effect of the initiative is most felt initially. Little attention is given to the starting data for manufacturing—the data that comes from design. However, you can’t have smart manufacturing if your process begins with dumb data. As Pink Floyd said, “You can’t have your pudding if you don’t eat your meat!”
An Experienced Millennial on Hiring the Next Generation
During DesignCon, I met with Geoffrey Hazelett, VP of sales for Polar Instruments. Even though he has been in EDA for a few years, Geoffrey is still in his thirties, which makes him a youthful cherub in this industry. I asked Geoffrey what he thinks about the new PCB designers and EEs entering this field, and what more can be done to expose young people to the world of PCBs.

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.
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.
Carl Schattke on Stackup Design and Managing the Component Shortage
At AltiumLive, I met Carl Schattke, CID+, a lead PCB designer with an American automaker. Carl and TTM’s Julie Ellis taught a packed class on good stackup practices complete with plenty of slides showing examples of all kinds of stackups. After class, Carl explained why the stackup is often the root of manufacturing problems downstream, and why today’s discrete component shortages are likely to be around for quite some time.
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.
A Drone's-eye View of the IPC APEX EXPO Show Floor

Happy Anniversary, Gerber Format: Looking Ahead to Digital Innovation
This year, we celebrate the 55th anniversary of the introduction of the Gerber machine language format. We can thank H. Joseph Gerber, the man who took manual PCB design to the next level with the automated photoplotter, for giving us this format in 1964. Gerber immigrated to the United States in 1940 with his mother following the death of his father during the Holocaust. Gerber started Gerber Scientific Instrument Company in 1948 to commercialize his first patented invention—the variable scale.
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.
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.
Birds of a Feather: PCB Carolina and the RTP Designers Council

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.
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
Life Beyond 10 Gbps: Localize or Fail!
Ideally, all interconnects should look like uniform transmission lines (or wave-guiding structures) with the specified characteristic impedance. In reality, an interconnect link is typically composed of transmission lines of different types (microstrip, strip, coplanar, coaxial, etc.) and transitions between them such as vias, connectors, breakouts and so on. Transmission lines may be coupled to each other that cause crosstalk. The transitions may reflect and radiate energy due to discontinuities in signal and reference conductors. The crosstalk, reflections and radiation cause unwanted and sometime unpredictable signal degradation.
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.
Julie Ellis: Communication and Fabrication Knowledge Critical for Designers
Field Application Engineer Julie Ellis of TTM sees it all: good designs, bad designs, and everything in between. Her classes on proper DFM techniques are always a big draw. She taught at the inaugural AltiumLive in 2017 and was back at this year’s event. I caught up with Julie and asked her to discuss some of the things she covered in class. As she points out, many issues could be eliminated if designers communicated with their fabricators and had a better understanding of how PCBs are manufactured.
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. The company is famous for selling nutritional supplements and soap, but apparently Amway has been busy diversifying over the years. I was interested in finding out more about Amway’s electronics development. Dugan sat down with me to discuss his role at Amway, and how this company grew into an $8 billion global giant.

AltiumLive to Feature Altium Designer 19 Release
This week, Altium Designer 19 will be officially launched to the public during AltiumLive, which takes place October 3-5 in San Diego. I asked Altium COO Ted Pawela to give us a preview of Altium Designer 19, and to explain how AD19 fits in with the company’s long-term plans. He also discusses Altium Live’s plan to provide PCB design content that is not vendor-specific to help support the entire industry, not just customers.
Lee Ritchey Returns to AltiumLive with 32 Gbps Design Class
Lee Ritchey was one of the instructors for last year’s inaugural AltiumLive event, which drew hundreds of PCB designers. Now, Lee is back, teaching a high-speed design class at next week’s AltiumLive in San Diego. That class is sold-out, but you can catch Lee teaching the same class at the January AltiumLive event in Germany. 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. Chuck recently spoke with Happy Holden, Andy Shaughnessy and Barry Matties about current trends in packaging, the need for product designers and manufacturers to communicate, and why no matter how cool the technology is, cost is still king.
Susy Webb: Training the New Generation of Designers
For years, I’ve been running into Susy Webb at PCB West, where one of the classes she teaches is PCB design basics. I always ask Susy about the class, especially the attendees’ backgrounds. Over the years, her class has begun drawing more and more degreed engineers, with fewer “traditional” PCB designers attending. I asked Susy to discuss the next generation of PCB designers, some of the trends she’s seeing among new PCB designers, and the need for designers to take charge of their own design training, whether their management agrees or not.
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.

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.
Making the Most of PCB Materials for 5G Microwave and mmWave Amps
Ready or not, 5G is coming, and it will require the right circuit materials for many different types of high-frequency circuits, including power amplifiers. 5G represents the latest and greatest in wireless technology, and it will be challenging to design and fabricate, starting with the circuit board materials, because it will operate across many different frequencies, such as 6 GHz and below, as well as at millimeter-wave frequencies (typically 30 GHz and above).
Mark Thompson: What Designers Need to Know about Fab
Mark Thompson wants to help PCB designers. He’s seen it all in CAM support at Prototron Circuits: the incomplete or inaccurate data packages, boards that are unnecessarily complex or over-constrained, and so much more. Mark just returned to writing his popular Design007 Magazine column, The Bare (Board) Truth, which addresses questions such as, “What happens to your design at CAM?” I asked Mark to explain why it’s so important for designers to communicate with their fabricators, and why they need to get out of the office and visit a board shop every now and then.
Design and Manufacturing Perspectives from DISH Technology’s Les Beller
I recently interviewed Les Beller, a long-time PCB designer who is now a manufacturing engineer for DISH Technology.

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.
Frontline's InStack Viewer Helps Designers and Fabricators

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.
Pulsonix Ready for 2018
Pulsonix has been developing PCB design software for almost 20 years, establishing a reputation for its full-featured, low-cost design tools. Now, the UK-based company wants to break into the US market, and Pulsonix recently showcased its latest tools at PCB West.

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.

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!”
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.

This conference drew hundreds of PCB designers, many of whom attended breakout sessions designed in accordance with the show’s motto, “Learn – Connect – Get Inspired.”
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.
Whose Fault is That Bad Board?
Years ago, I held a position in an EMS company where projects were analysed before manufacturing. We found that even some of the best and most innovative circuits could not be manufactured. Why? Because the PCB designer, an electronic engineer, was not acquainted with the fabrication process. He had no idea about technological requirements necessary for electronic production. I know another designer who learned, finally, the importance of the thermal relief pad for heat restriction during reflow for a good soldering. His response? “Oh, was that what they were for? And to think I worked so much to remove them!”

Rigid-flex Design Tips and Best Practices
While the traditional “design-separately-then-assemble” approach minimized potential issues with the flex portions of the product, it also had several inherent disadvantages. These include the cost associated with the physical connectors; the space required for the physical connectors; the need to properly manage interconnects that have to transition between the separate rigid and flex PCBs (through the connectors); and, of course, the time and cost associated with assembly. The move to the current generation of rigid-flex technology mitigates these issues; however, they are replaced with a different set of challenges and concerns.
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.

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.

Sensible Design: Conformal Coatings - Beware the Boards that ‘Bare’ All!
This month, Phil Kinner departs from his usual format of providing five essential facts about conformal coatings. 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.
Beyond Design: How to Handle the Dreaded Danglers, Part 1
Dangling via stubs can distort signals and decrease the usable bandwidth of the signal. A via stub acts as a transmission line antenna, and has a resonant frequency determined by the quarter wavelength of the structure. At this frequency, the transmitted signal is greatly attenuated, by up to 3dB. For low-frequency signals, this is not much of an issue, but for higher-frequency signals, this issue becomes a problem.

Brooks' Bits: Your Traces Have Hot Spots!
The reasons for the temperature variation at high temperatures are not too hard to understand. There may be minor contamination under the trace or in the copper that accounts for it. Certainly, at higher temperatures (say above about 300°C) the board may begin to delaminate, severely disrupting its cooling characteristics. There may be small variations in trace width or thickness that help account for the delam, and these effects would be randomly distributed along the length of the trace.
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.

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

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.
