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?

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.

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.
Performance Evaluation of Thin-Film Embedded Resistors
Thin-film microstrip circuits have been widely applied in microwave communications, electronic countermeasures (ECM), and aerospace applications, etc. When manufacturing thin-film ICs, it is very important to apply deposited thin-film resistor material to fabricate high-accuracy and highly stable thin-film embedded resistors. Thin-film ICs call for thin-film resistors that meet stringent requirements.

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.

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.
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.
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.

Let's Talk Testing: Don’t Reinvent the Wheel—Find an Expert!
Back in the day when I was an engineer fresh out of college, I quickly learned that experience is the solution to many problems. Now that being said, experience comes in many forms…it could be knowledge learned from a textbook, it could be an observatory comment jotted down in a notebook, it could be a conversation with a co-worker or colleague, or it could be an Internet search that finds a scholarly technical article, etc.
Sensible Design: The Little Guide to Resins
I would like to start this series of columns by going back to basics, questioning the core rationale for potting and encapsulation with resins, their fundamental chemistries and how each resin type differs one from the other—indeed, how their individual properties can be exploited to maximise performance under a wide range of environmental conditions.
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.
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.
The Shaughnessy Report: Voices of the Industry
We asked readers like you to share your thoughts about PCB design. Your replies were all over the map. Of course, as journalists, we are drawn to your complaints and challenges—our publications exist to help you address these challenges. And you were not shy about sharing your complaints! Designers’ complaints haven’t changed much since I've been covering this segment.
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.
Beyond Design: The Rise of the Independent Engineer
With the changing demographics, the old-timers in our industry—the master PCB designers—are about to retire and hand over the exacting job of PCB design to the Gen-X and Ys. These generations, shaped by technology, will tackle the most demanding designs without possessing the experience that we veterans benefit from. And to top it off, these up-and-coming designers will be degreed engineers who have to cope with both design and layout tasks as the specialized PCB designer’s positions are phased out.
The Gerber Guide, Chapters 15 and 16
Before sending your Gerber files off to your fabricator, you are often advised to check them using a reputable Gerber viewer such as GC-Prevue. This is excellent advice. Note that this involves more than just verifying that the viewer displays your intended image: It is important that you check too that the file is valid.
Designing for Profitability: Don’t Over-Materialize
John Bushie, applications engineering manager at American Standard Circuits, spoke with Barry Matties recently about how designers can avoid over-materializing. He also outlined the benefits of designing for profitability.
Making Digital and Analog “Play Nice” at Peavey
Most guitarists have owned a Peavey Electronics amplifier or instrument at some point in their lives. Peavey originally drew accolades for their line-up of high-quality, budget-friendly products. Now the company also develops high-end instruments, amps, and live sound equipment. Peavey was also the last major American musical equipment maker to have product manufactured overseas. I met with Tom Stuckman, an electrical engineer at Peavey, during NAMM and asked him about the technical challenges he faces and what it’s like working at Peavey.

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.
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.
Cadence Paper: Automating Inter-Layer In-Design Checks in Rigid-Flex PCBs
Flexible PCBs make it possible to create a variety of products that require small, lightweight form factors. As flexible PCB fabrication technology has matured, new design challenges have emerged. This paper discusses some of the key challenges and introduces a new PCB design approach that enhances productivity through in-design inter-layer checks.

In his most recent State of the Union address, President Obama highlighted a remarkable trend of recent years: the turnaround in many corners of America’s manufacturing sector. Nearly 900,000 new jobs have been created by U.S. manufacturers in the last six years.
Enhancing Thermal Performance of CSP Integrated Circuits
In order to meet size and weight requirements, constraints of portable electronic designs often force PCB designers to reduce the size of components and PCB real estate area. To meet these demands, the use of CSP packages to shrink the PCB area needed is a common change in designs. As a result of the reduction of total PCB area, the available options to move heat and route high-power PCB traces is also reduced. Furthermore, the thermal performance cannot be matched when a QFN is compared to an equivalent CSP package.
Innovative Circuits Sees Healthy Medical Market
Medical electronics is one of the fastest growing segments of our industry. Alpharetta, Georgia-based Innovative Circuits is at the forefront of fabricating medical PCBs, both flex and rigid. I asked Innovative Business Development Manager Amir Davoud to give us a solid diagnosis of the world of medical PCBs.
Medical PCB Design: Not Just Another High-Rel Board
Some of the coolest new electronic products have come courtesy of the medical market. I wanted to find out more about this fast-growing segment, so I contacted Kenneth MacCallum, an engineering physicist with StarFish Medical. MacCallum, an engineering physicist who designs PCBs for medical applications, explained why medical PCBs are not quite like other high-reliability boards.
Happy’s Essential Skills: The Need for Total Quality Control (Six Sigma and Statistical Tools), Part 2
The statistical representation of Six Sigma describes quantitatively how a process is performing. To achieve Six Sigma, a process must not produce more than 3.4 defects per million opportunities. A Six Sigma defect is defined as anything outside of customer specifications. A Six Sigma opportunity is then the total quantity of chances for a defect.
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.
Happy’s Essential Skills: The Need for Total Quality Control (Six Sigma and Statistical Tools): Part 1
In this first of many columns covering my "Twenty-Five Essential Skills Every Engineer Needs to Learn," I will expand on each of those skills. To read the introduction to this series, which published in the January issue of The PCB Magazine. As a quick recap, here are the 25 skills that I will be writing about over the next 18 months or so, to publish every three weeks or so in the PCB007 Daily Newsletter.
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.
Good In, Good Out: Bay Area Circuits Discusses Data Strategies
A lot of companies talk about the importance of good data management, but for some firms, this amounts to little more than lip service. Then there are companies like fabricator Bay Area Circuits. I recently sat down with Bay Area Circuits President Stephen Garcia and COO Brian Paper to discuss how automating and upgrading their data systems has significantly cut down overall process time, as well as their drive to educate young PCB designers and actively promote the industry to the emerging electronics industry workforce.
All About Flex: Flexible PCB: What’s in a Name?
Flexible PCB is a common term that is synonymous with flexible circuits. While the term “PCB” is generally used to describe rigid printed circuitry, “flexible PCB” is a little contradictory because “boards” aren’t really flexible. Some companies, like All Flex, design and manufactures flexible PCBs, but not rigid PCBs.
Arlon’s John Wright Discusses New High-Performance Materials
During productronica, European Editor Pete Starkey interviewed Engineering/Quality Manager John Wright of Arlon. They discussed Arlon’s new 85HP ceramic-filled polyimide, as well as a non-woven aramid material, suitable for space applications, that is a drop-in replacement for a similar material discontinued by a competitor in 2006.
The SMT Internet of Things— Back to Basics
Different people have different understandings and expectations about what the Internet of Things (IoT) actually is, especially with respect to how it could work and what it could bring to the SMT assembly industry. There are a lot of expectations to fulfil as principles behind innovations such as Industry 4.0 take hold.
Lightning Speed Laminates: Impact of Final Plated Finish on PCB Loss
A variety of plated finishes are used in the PCB industry. Depending on the circuit construction and other variables, the plated finish can cause an increase in PCB insertion loss. The plated finish used on the outer ground planes of a stripline circuit have minimal or no impact on insertion loss. However, microstrip or grounded coplanar waveguide circuits, which are common on the outer layers of multilayer high-frequency PCBs, can be impacted by the plated finish for increasing the insertion loss.
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 Challenges of Being Competitive in Automotive Electronics Manufacturing
Simple electronics were gradually introduced into automobiles from the earliest times. At first, these were just simple electro-mechanical devices to make cars work without manual effort, such as to start the engine and keep windshields clear. But in this past decade, we have seen the effects of the gradual growth of issues with electronics systems, with recalls caused by safety issues that cost automotive manufacturers millions of dollars. Electronics within an automotive environment today requires a new approach to ensure a higher level of quality perfection.

The Shaughnessy Report: Car Talk
The automotive electronics segment has exploded. Early cars didn’t have much in the way of electronics. Even in 1950, electronics made up only 1% of a car’s cost. But that figure is expected to hit 35% in 2020, and 50% in 2030. The global automotive electronics market is forecast to hit $314.4 billion by 2020, and that means a whole lot of PCBs.
Jack Pattie Discusses New Ventec Facility
Jack Pattie, CEO of Ventec USA, discusses the company's newest laminate facility, which recently opened in Northern California. He explains how this location, the company's fourth, will help Ventec better serve customers in that region.
The Reindustrialisation of Europe
With an inquisitive mind and a head for challenges, besides the ability to think outside the box and the courage to dare to be different and strive to be first, Spirit Circuits MD Steve Driver can be relied upon to grab the attention of an audience of PCB professionals. As keynote speaker at the Institute of Circuit Technology Hayling Island Seminar, he lived up to his reputation with a motivational presentation, the two themes of which exemplified his latest entrepreneurial venture.
The automotive electronics segment has exploded. Early cars didn’t have much in the way of electronics. Even in 1950, electronics made up only 1% of a car’s cost. But that figure is expected to hit 35% in 2020, and 50% in 2030--and that means a whole lot of PCBs. This issue of The PCB Design Magazine features the impact of increasing electronics content in cars on the PCB design and manufacturing industry.
Kelly Dack and Mark Thompson Unite in the War on Failure
There’s been a lot of talk about fighting the war on failure in the PCB industry. But what strategies should our generals follow to prosecute this war? What exactly constitutes a failure in the first place? Is this war even winnable? I recently spoke with longtime designer Kelly Dack and CAM support veteran Mark Thompson of Prototron Circuits about the best battle plans for beating failure, and why designers and manufacturers must team up against this common enemy.
Training the Next-Generation Engineer: When Does it Begin and End?
American engineering companies are seeing a severe shortage of the homegrown engineers required to compete globally. Just go into any company today and you’ll notice that increasingly, the engineers are foreign-born. Our local universities are seeing fewer and fewer American engineering students each year. Universities are also seeing a growth in female students. Over 50% of college student are now female, and women traditionally are not attracted to science and engineering majors. What is causing this imbalance?
Fighting the War on Failure
No one in this industry sets out to fail, except failure analysis test engineers. But failure is a part of life for designers and manufacturers of electronics. Our reader surveys show that failure affects nearly everyone in the PCB industry: designers, fabricators, assembly providers, OEMs, and suppliers.
Strategies for Improving PCB Procurement
The PCB procurement process has certainly changed over the years. Some people are happy buying a board from a website, but for others the demands are different. Russ Adams should know; he’s the sales manager for Prototron Circuits, a PCB fabricator that has been in business for nearly 30 years, with facilities in Redmond, Washington, and Tucson, Arizona. I recently met up with Adams to discuss customers’ evolving requirements, along with his ideas for lowering the total procurement cost.

Polar Talks Impedance and Insertion Loss Testing
Product Specialists Michael Bode and Geoffrey Hazlett join Guest Editor Dan Feinberg to talk about controlled impedance and insertion loss testing.
What is DFM, Really?
Mark Thompson relates, "The term "design for manufacturability" has been used for many years now, but does everyone really understand this concept? For instance, do you design for 10%? Do you design for a specific manufacturer's capabilities, therefore making you less likely to seek alternative fabricators? How are your drawings worded?"
Design for Profitability: Avoiding Fabrication Issues and Minimizing Costly Revisions
At last, PCB designers are finally realizing the power they wield: They have the power to design profit into the board, or, conversely, increase costs and remove profit from the PCB. Mark Thompson reviews the challenges fabricators routinely face and presents typical DFP solutions affecting the bottom line.
Letter: Let's Reestablish the U.S. PCB Design Community
Dan Smith may have been sniffing paint fumes, but that didn't stop him from writing a letter to the editor after reading a recent "Shaughnessy Report". He asks, "What will it take to reestablish the U.S. PCB design community as a significant new product contributor? More education? Smarter tools? Intelligent factories?"
