Catching up with Artnet Pro’s Meir Polack
Interested in all aspects of our industry, I have lately been especially focused on our suppliers, because more and more of my board shop clients are concerned about their vendor support chain as more of them are either reducing their presence in North America or leaving altogether. I am also keenly interested in companies whose mission it is to help the PCB industry survive, especially a company that does not abandon the “little guys,” but rather is focused on helping those smaller companies to compete with the giants whose goal is to run them over.
Let’s Talk Testing: Welcome Your Product to the Real World!
The days, weeks, and (sometimes) years that go into a product’s development usually are incomprehensible to the lay person. Like laws and sausages, no one wants to really understand what has gone on behind the scenes to make your “thing” a reality. They just care that your widget makes their life easier and/or more enjoyable!
Event Review: 7th Electronic Materials and Processes for Space Workshop
This year's Electronic Materials and Processes for Space Workshop discussed a wide range of technology issues and developments when it comes to PCB fabrication and assembly for space applications. From addressing reliability issues to dealing with cracks that may form during thermal cycling, to REACH regulations and their impact on space hardware, and tin whisker growths. Barrie Dunn provides the highlights.
If you have paid any attention at all to our newsletters and other publications, you should have been aware of this month’s topic long before opening this magazine. We tried to reach… everybody, so we could get their thoughts on the industry for this issue.
From Afterschool Robotics Club to FIRST Competitions
Seven years ago, Joel Bruxvoort, a science teacher at Jefferson High School in Daly City, California, started a robotics club as an afterschool program. Now, his club has two teams competing in events for FIRST (For Inspiration and Recognition of Science and Technology), an international youth organization developed to advance STEM subjects around the world.
Launch Letters: Embrace Your Brand
Whether it be your company brand or personal brand, you have to fully embrace it and believe in it. It’s the trust, knowledge and confidence you communicate to your customers, the community, and the industry you interact with and react to every nanosecond. In his latest column, Barry Lee Cohen explains why, and provides some pointers on how you can launch—or relaunch—your brand.
Happy’s Essential Skills: Engineering Economics (ROI)
Engineering economics is fundamental in engineering, especially for manufacturing support. For simplicity, I am using the term here as a process engineer for printed circuit equipment and automation of production.
A Day with Pete (Starkey)
Usually the one conducting the interviews, I-Connect007’s own Pete Starkey recently found himself on the other side of the microphone when I spent time with him in his hometown of Market Bosworth, England. There, between hiking and gardening, we found time to discuss Pete’s rich history in the PCB industry and the many changes and surprises he’s seen in the manufacturing process over the years.
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.
Shane Whiteside and Summit Interconnect: Aspiring to New Heights
A few weeks ago I was privileged to meet with Shane Whiteside in Anaheim, California, at KCA Electronics. Whiteside, former COO of TTM, has helped launch a new company—Summit Interconnect— which encompasses the recent acquisition of KCA Electronics and Marcel Electronics International. Once again assuming an executive role, this time as CEO and president, Whiteside shared his story, strategy and vision for this new chapter.
All About Flex: Considerations for Impedance Control in Flexible Circuits
Impedance can be thought of as a system’s opposition to alternating or pulsing electronic current. The unit of measurement is ohms, the same unit of measurement in a direct current system. However, the components for calculating impedance are much more complex than DC resistance.
Happy’s Essential Skills: Benchmarking
Benchmarking is a process that measures how a company is performing against those industry leaders. It is used to better understand how outstanding companies perform, and then helps your company develop plans to improve or adapt specific best practices.
Mentor Video: Impact of Power Integrity on Temperature
One of the most common outputs from a DC Drop simulation is a current density plot. But how much is too much current density? The answer depends on temperature rise, and requires a PI-thermal co-simulation to properly characterize.
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.
This month's column has a higher percentage of IC coverage than normal for several reasons. The end of Moore's Law regarding transistor scaling will be dead by 2021 as will be replaced by 3D integration according to the International Technology Roadmap for Semiconductors (ITRS).
All About Flex: Creating Via Holes in Flexible Laminates
Almost all double-sided and multilayer flexible circuits require through-holes or vias to enable an electrical connection between conductive layers. Creating a reliable plated via requires several critical steps. The first one is creating the through-hole.
Inside Spirit Circuits
I was recently treated to a factory tour with Spirit Circuits’ Managing Director Martin Randall, to learn more about their process line and how it has evolved over time. In the discussion following, I learned about Spirit’s involvement in the China market and how they’ve structured their business to handle quick turn prototypes locally and high volume abroad.
High-Throw Electroless Copper– New Opportunities for IC Substrates and HDI Manufacturing
The one constant in electronics manufacturing is change. Moore’s Law, which successfully predicted a rate of change at which transistor counts doubled on integrated circuits (ICs) at lower cost for decades, is ceding to be an appropriate prediction tool.
Happy’s Essential Skills: Project/Program Management
No matter what your job, you may have to manage, or play an active role in, a project at some point during your career. It takes a great deal of skill to do this well, but the time you invest in building good project management skills can pay off enormously.
Using the Type 1 Gauge Study to Assess Measurement Capability
Measurement capability is a critical aspect of ensuring product quality, therefore a measurement system must be assessed before being used on products. Understanding how to assess measurement capability becomes critical. The Type 1 Gauge study is typically the first step in a measurement system analysis program. Type 1 Gauge parameters are explained, and a worked example using electroless nickel immersion gold (ENIG) is provided.
A Thermal Conductivity Measurement Method, Adapted to Composite Materials Used in the PCB Industry
Most of today’s printed circuit board base materials are anisotropic and it is not possible to use a simple method to measure thermal conductivity along the different axes, especially when a good accuracy is expected. Few base material suppliers’ datasheets show X, Y and Z thermal conductivities. In most cases, a single value is given, moreover determined with a generic methodology, and not necessarily adapted to the reality of glass-reinforced composites with a strong anisotropy.
Book Review: Pinterest Power
Let’s be honest: Pinterest is hot right now. It’s so hot there are shelves full of books about what Pinterest is, what you do with it, and how you can increase your business by using it.
Round Robin of High-Frequency Test Methods by IPC-D24C Task Group (Part 1)
Currently there is no industry standard test method for measuring dielectric properties of circuit board materials at frequencies greater than about 10 GHz. Various materials vendors and test labs take different approaches to determine these properties. It is common for these different approaches to yield varying values of key properties like permittivity and loss tangent.
John Tusant on Geek-A-Palooza

The PCB industry in Brazil has gone through several changes over the last decade. Our customers have been demanding better quality and higher-reliability products more than ever before, but few things have changed as much as impedance control. PCBs with impedance control requirements have become the engine of the market, and finding solutions to fit the customer’s needs is extremely challenging.
Viking Test Services: Much More than Test
Recently, 007 Technical Editor Pete Starkey and I toured Viking Test’s facility in Hants, UK where we met Managing Director Jake Kelly to learn about the history of the company, their recent involvement in the Indian PCB market, and what he thought of the EIPC Summer Conference.
All About Flex: Variability and Quality Costs
Statistics are terms used for measurements that describe groups of numbers. The most common averaging statistics are mean, median and mode. Mean and average are often used interchangeably, a statistic with all numbers added together and then divided by the quantity of numbers.
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.
Building Reliability into the PCB, Part 1
Sometimes there is confusion among PCB engineers and quality managers as to what constitutes reliability. Some may say that reliability refers to avoiding PTH failures such as corner cracks or interconnect defects. Then there are those who subscribe to a wider range of failure criteria to determine whether or not the final product is reliable for long-term service.
Let's Talk Testing: Seeing is Believing in Fractographic Analysis
One of the more common types of failure analysis is the investigation of something that has broken. For this column, we will be discussing a broken material, or, more commonly, a fractured or cracked material.
Testing Todd: Test & Measurement—The Case for Validation
Test and measurement (T&M) are terms that can strike fear into the most robust of minds. Many engineers create designs and products of the future with specific results predicted for performance.
Faster, More Accurate AOI is More Important than Ever
Among PCB manufacturers, there is a common perception that AOI has not changed much since it was introduced decades ago. Over the last few years, however, new advanced technologies have made AOI solutions smarter, faster and much more accurate. AOI system data have even been integrated with newly developed automatic 3D shaping tools.
Patty's Perspective: Delving into Test and Inspection
I’ve always been a wet processing person, if not always in a PCB shop, at least at heart. My undergraduate degree is in chemistry and I cut my teeth working on electroless copper processes (just a metaphor, mind you!). Testing, testing and more testing in R&D can be sooo boring and repetitive.
All About Flex: Taguchi Design of Experiments and Flexible Circuits
Reducing variability in a process, or a sequence of processes, can require a significant and structured amount of work and analysis. One must develop an understanding of critical variables and determine methods to control them. Statistically based experiments are often needed for proper analysis.
Happy’s Essential Skills: Understanding the Concept of Managing Management Time

The past few months have seen a rash of PCB deals in North America, for a variety of reasons. Tom Kastner lists some of the deals completed during the past eight months.
Launch Letters: Give Your Literature Some Lovin’
Collateral is such an ugly word. As the late, great Rodney Dangerfield would have put it, brochures, sell sheets, process manuals, and other sales support tools often get no respect in our digital world. Even the convenience of downloading a PDF is scoffed at by today’s millennials who rely on the “Almighty App” and the “All-Knowing Cloud” to view, digest and store information.
Catching up with Sunrise Electronics’ Ashok and Jigar Patel
I had been hearing about Sunrise Electronics for many years, so when Ashok asked me to come and see them for myself, I jumped at the chance. It was one of the most amazing plant tours that I’ve been on in a long time. I wanted to know more, so we sat down and had a chat.
Standard of Excellence: The Future is in Fine lines
The age of much finer lines and spaces is upon us. After years of slowly moving towards this technology our customers are now demanding that all of us provide them with fine lines and spaces. Our new trend in electronics is for denser and denser circuitry on smaller and smaller real estate.

We spend most of our working lives behind software, delivered to our fingertips with the promise of making things easier, faster, better, and getting us to our deadlines ever faster.
Designers Notebook: Specifying Lead-Free Compatible Surface Finish and Coating for Solderability and Surface Protection
A majority of the components furnished for electronic assembly are designed for solder attachment to metalized land patterns specifically designed for each device type. Providing a solder process-compatible surface finish on these land patterns is vital; however, selection of the surface finish on the circuit structure, whether plated or coated, can be greatly influenced by the components’ terminal metalization and the specific alloy composition used for the assembly process.
The way that I see the problem relates to overcapacity for fabricators in the consumer segment of devices with flat panel displays—mobile and otherwise—as well as a decline in notebook PCs, TVs and other household and portable electronic devices. Additional culprits include the improved packaging designs as well as more powerful chips replacing multiple ICs—both requiring less board real estate.
The Importance of Design for Profit (DFP)
In this interview, Interconnect Design Solutions’ Mike Brown and I took a few minutes during the recent Geek-A-Palooza event to discuss the importance of material selection and designing for profitability, how automation affects the design process, and the future of the design community.

The 21st Century PCB Factory– Designed to Eliminate Offshore Cost Advantages
Over 15 years have passed since North America and Europe ceased being the center of worldwide PCB fabrication and were supplanted by a Chinese market with low-cost labor, lax environmental requirements, and strong government support. In just a few short years, the superior offshore cost advantages of this new dynamic put volume PCB production in the West out of business, aside from the military and specialty technology applications contained in the few shops that continue to exist today.
Laser Pointers: Special Edition—Those Five Words I Didn’t Expect to Hear
I’m going to hijack the column this month for kind of a public service announcement regarding a topic that hit very close to home for me, and it may well hit home for others. On February 18, 2016, I heard the words, “Mike, you have bladder cancer.”

Against the Density Wall: Landless Vias Might be the Answer
I saw my first landless via multilayer while visiting NEC in Japan in 1985. You may not know much about landless vias. This has been a well-kept secret for the last 30 years, possibly because it is not permitted on military boards, and therefore, discouraged in all IPC standards. So when a company showed us their landless via boards, we said, "You can't do that!"
