Part 2: EIPC’s 2018 Winter Conference in Lyon, Review of Day 1
We continue with the rest of Pete Starkey’s report on Day 1 of the EIPC Winter Conference in Lyon, France. Included in this segment are presentations by Ventec, Ericsson, TTM and others, plus photos of their evening tour of Alstom.
Out-of-the-Box Innovation Strikes a Chord at NAMM 2018
The National Association of Music Merchants (NAMM) holds two shows each year; the first is in Anaheim in January, and the second in Nashville in July. The January show is huge, attracting 100,000 visitors during its four-day run. My friend and editor (and bass player) Dan Feinberg has discussed how difficult it was for him to cover the CES show in a few days, and I must echo that sentiment about NAMM. It is one gigantic show.
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.
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.
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.
Video from productronica 2017: Karel Tavernier on Ucamco's New Communic8tor
European Editor Pete Starkey and Ucamco Managing Director Karel Tavernier discuss Ucamco’s cloud-based Communic8tor platform which facilitates two-way communication between the CAM engineer and the PCB designer, or any other party involved in the manufacturing process. This gives real-time access to image data and annotations, enabling queries to be resolved, changes to be approved, and a full communications history to be maintained.
Happy Holden and Charles Pfeil Discuss the Past and Future of PCB Design, Part 2
In Part 2 of this feature interview, I continue my conversation with industry icons Happy Holden and Charles Pfeil at the recent AltiumLive 2017 event in San Diego. 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.
Meet One of the Industry’s Newest PCB Designers
Molly Knewtson is a recent graduate now working for a pharmaceutical company as a mechanical engineer. She was asked if she would consider learning PCB design and taking on some design projects. She agreed, though she had never considered circuit design as a career path. I sat down with Molly at PCB West to learn how she came to this position and what might be done to inspire more people from her generation to join the industry.
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.
The State-of-the-Art in PCB Pre-production Engineering
If there’s one benefit of old age, it’s being able to remember the introduction to our industry of technologies that may be taken for granted by the present generation, but were revolutionary at the time. I can recall the history of Ucamco as far back as the late 1980s when, as one of the very early adopters of the DISC laser plotter and its associated electronic PCB front-end tooling system, our company gained entry to a spectacular new world of pre-production engineering capability.
Fault-Finding: It’s All About Prevention, not Blame
There are thousands of things that can go wrong during the design and manufacture of a PCB assembly. One might say that it is an absolute miracle when a PCB goes through all of its phases—design, fabrication and assembly—and operates successfully. But there are some management and customer cultures who naively attempt to resolve problems by seeking out the culprits and shouting “Off with their heads!”
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.
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.
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.
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.

Global Impact on European PCB Fabrication: EIPC Summer Conference 2017, Day 2
The second day saw the conference room full once more, the late networking session in the bar having resulted in no significant casualties, and I was pleased to accept the invitation to moderate the first session, on processes and materials for flexible PCBs.
Whose Fault is it When the Board Fails?
In an upcoming issue of The PCB Design Magazine, we will discuss a question that you've undoubtedly faced in your job: Whose fault is it when the board fails? Of course, everyone likes to blame the PCB designer. But think about it. Is the board shop at fault, or perhaps the EMS provider? Is it the customer's fault, or does the designer bear some of the blame after all? Take this quick survey and let your voice be heard!
HDP User Group 2017 European Meeting Highlights Technology Progress
The conference facility at the offices of Oracle, in the royal burgh of Linlithgow in West Lothian, Scotland, was the venue for the 2017 European meeting of the High Density Packaging User Group.

Bruce Mahler Discusses Ohmega’s Resistive Material Technology
Bruce Mahler, vice president of Ohmega Technologies, sat down for an interview with me at DesignCon 2017. He discussed the company’s latest embedded resistive materials, as well as some of the drivers and challenges in that segment of the materials industry.
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.
IMPACT Washington 2017 Just Around the Corner
IPC's Government Relations team has worked around-the-clock to ensure that IMPACT Washington D.C. 2017 is the best yet. During this two-and-a-half day event, executives from IPC-member companies will have the opportunity to speak with leaders in Congress and the Administration in support of our common priorities.
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.
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.

Publisher Barry Matties and Managing Editor Andy Shaughnessy join Bob Neves of Microtek Labs for a review of IPC APEX EXPO 2017 and a look at the state of the PCB industry.
Help Wanted! Our 2017 Industry Hiring Survey
This month we conducted an industry survey on plans for hiring during the year. Included here is a summary of the results. We started by simply asking, “Do you plan to hire additional people this year?” More than half of the respondents answered yes while about a third said no—which we take as an optimistic sign that our industry plans to expand in 2017.
True DFM: Taking Control of Your EDA Tool
We PCB designers are doing some truly great things with our layout tools. But we must remember that these tools are so powerful that they will sometimes allow us to design things that can’t be manufactured! We must collaborate with our fabricator and assembly brethren and embrace the best DFM practices, or face the consequences downstream.
Flex and Rigid Sales and Marketing with Al Wasserzug
After decades in the PCB industry, Al Wasserzug of Cirexx International has seen marketing and sales trends come and go. I recently caught up with Al and interviewed him via email about the latest sales and marketing techniques, the value of traditional methods such as trade shows and conferences, and the particular characteristics of marketing flex circuits.
CES 2017: Disruptive Technologies
Those of you that have read my previous columns covering CES 2017 know that at recent CES shows I have seen many drones, autonomous cars, IoT devices, robots, and many other items ranging from robots who stand in for your doctor to smart trash cans who tell you via Alexa, Google, or soon, Cortana on your own computer, that since you have thrown away two empty milk cartons in the last few days it may be time to order more milk; just say yes and consider it ordered.
CES 2017: Press Day, LaunchIt and Showstoppers
Before the show opens, CES provides two days and evenings not open to the general attendees, to enable companies, large and small, an opportunity to present their new offerings to the press. These opportunities range from small meetings with individual members of the trade press to huge events such as those presented by Samsung, Asus, Sony, Intel, Panasonic and others, with literally several hundred in attendance.
Sales and Marketing with DownStream Technologies
From its inception, DownStream Technologies has been a new kind of software tool company. DownStream’s post-processing tools address one of the most unpopular parts of the design process: documentation. DownStream's CEO Rick Almeida discusses some of his firm’s marketing and sales methods, the trends that he sees, and the influence of the Internet on marketing.
Much Ado About Sales and Marketing
We recently surveyed our readers to get a better idea of what company leaders thought about sales and marketing. We sent this survey to several sales leaders; the results were informative, at times surprising, and even a bit disappointing, especially when participants reported that they had no sales and marketing plan at all. Does your company fall into that category?
TTM President Thomas Edman on the Global PCB Market, Technology, and More

Patty’s Perspective: Take Me to Your Leader
We must have touched a real hot button when we decided to do this issue on leadership. When we sent out our survey on the topic, we received a lot of responses, which we’ll review in a separate article, plus many of our regular columnists were inspired to write on the subject.
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.
Designing with Fine Lines and Features
Albert Gaines is the owner and senior PCB designer at HiGain Design Services in Norcross, Georgia. He’s been a PCB designer since 1981; he's designed a variety of boards in that time. I asked Albert to talk about some of the finer lines and features that come through his shop, as well as some design techniques for boards with tight tolerances.
Taylor Guitars Protected with Analog, RF Circuitry
Trenton Blizzard is an electrical engineer at Taylor Guitars and part of the team that developed the TaylorSense shock and climate change protection system. At the NAMM show, Trenton spoke with me, along with Editors Dick Crowe and Dan Feinberg, about this new device, and what it’s like being an electrical engineer for a “woodworking shop.”
Sensible Design: Coatings—Five Essentials for Designers
In an ideal world, PCB designs would not have an inherent weak point for corrosion; unfortunately, in the real world, they do. When a weak point is revealed, you are better equipped to deal with it. Often the spacing of components, board finish and distance to ground planes can be optimised for corrosion resistance.
Changing the World of PCB Rapid Prototyping
Tony Tung is a recent graduate from Taiwan who has come up with a new way for PCB designers and makers to create breadboards using printed paper circuits. I caught up with Tony at the recent San Mateo Maker Faire and sat down with him to learn more about this project.

John Coonrod of Rogers Corporation gave a keynote presentation at the recent Geek-A-Palooza trade show, concentrating on printed circuit board fabrication’s influences on insertion loss. I sat down with John to learn more about his presentation and what OEMs and designers need to be aware of to avoid insertion loss.
PADS Paper: 10 Things to Know about Thermal Design
As designs get smaller, power densities at all packaging levels increase dramatically. Removing heat is critical to the operation and long-term reliability of electronics, and component temperatures within specification are the universal criteria used to determine the acceptability of a design. This PADS paper discusses 10 things designers need to know about thermal design.
Design Automation Tools, Today and in the Future
Kelly Dack has been designing PCBs for over three decades, at OEMs of all kinds. Now a PCB designer with a Washington state contract manufacturer, Kelly enjoys waxing philosophic about PCB design and design automation in general. I asked Kelly about the direction EDA tools are headed, and whether he’d like to see more control, or more automation in his PCB design tools.
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.
Sunstone Circuits R&D: 3D Printing Great for Prototyping
We’ve been hearing a lot about 3D printing for the past few years. But where does 3D printing fit in with traditional rigid circuit board development? Sunstone Circuits recently completed a project that focused on that very question. Sunstone Product Manager Nolan Johnson explains why 3D printing is a viable option when it comes to jigs and parts of the support infrastructure that are needed when prototyping today’s emerging technologies.
Happy’s Essential Skills: Technical Writing
Technical writing is one of those topics that they don’t really talk about in college—at least not where I went. Writing and English has never been a strong like of mine compared to science and math. So I did my required time in English and wrote my lab reports the best I knew how.
Tim's Takeaways: The Principles of Hybrid Design, Part 1
What exactly is a hybrid design? We are seeing more and more of our customers exploring the world of hybrid design, and we are getting new customers for whom hybrid design is their sole focus. The world of hybrid design is growing and we have lots of hybrid-specific functionality built into our software that helps designers conquer the unique hybrid design requirements.

Tara and Judy explain why this is not just another boring technical talk, and attendees will definitely enjoy themselves.
Standard of Excellence: Tips for Finding a Great PCB R&D Partner
This new column, Standard of Excellence, represents a cooperative writing effort by a team of experts at American Standard Circuits. This month, we begin with CEO Anaya Vardya, who focuses on R&D. In his piece, he provides his insights on what characteristics to look for in a good R&D PCB fabrication vendor partner, and a few things that are expected of them to do for you.
Catching up with…PNC: Open House Planned for May
I’m a great believer in open houses. Any time customers and vendors get together to learn and talk about what they can do for each other it’s a good thing. That’s why, when I heard that PNC, in Nutley, New Jersey, planned to hold an open house on May 20, I wanted to learn more about it. So I called my friend Sam Sangani, the company’s owner, to learn more about it.
IPC APEX EXPO: New Arlon Materials Address Design and Fab Challenges
Brad Foster, VP and general manager of Arlon, discusses some new laminates and pre-pregs that help designers and fabricators address a variety of challenges. He explains how Arlon works with customers to help them with stack-ups and other issues.
Manufacturing Institutes Can Boost the Nation
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.

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.
A Review of the Opportunities and Processes for Printed Electronics (Part 1)
As microsystems continue to move towards higher speed and microminiaturization, the demands for interconnection are opening up new opportunities for "innovative" interconnects. In the first part of this five-part article series, Happy Holden gives a brief background on printed electronics, as well as presents key technologies that are being employed for PE production.
How to Successfully Purchase PCBs
How do you go about purchasing reliable and durable PCBs at the lowest possible cost? A key success factor is to provide the prospective suppliers with accurate and clear specifications, and to keep a close eye on the quality of the boards once they are in production.
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.
