PCBs Are Moisture-Sensitive Devices
Research by SMT & Hybrid GmbH (now SMT Elektronik) was conducted just prior to the original publication of IPC-1601, which now provides detailed guidelines for the packaging and storage of PCBs, both from the PCB manufacturer and at the assembler’s manufacturing floor.
Reliability Takes on a New Urgency
Consumers wanted a reliable car that wouldn’t break down on the road; a computer that wouldn’t crash; a phone network that wouldn’t drop our calls; the plane we were hurtling across the sky in to stay in the air and land safely, with the wheels down. In retrospect, those seem rather simple wants, and the industry certainly wants to deliver.
Atotech on Challenges and Opportunities in PCB Manufacturing
Abel Ruivo, Atotech Deputy Business Director of Electronics for Greater China, and Daniel Schmidt, head of Global Marketing for Electronics at Atotech Group, spoke with I-Connect007 about the various challenges of PCB manufacturing in China, as well as about the opportunities in the sector.
BGA Fanout Routing Overview
PCB developers are deluged with new challenges caused by increasing density and smaller components. Ball grid arrays (BGAs) create particular challenges during layout, with hundreds of connections in just a few square centimeters. Fortunately, designers now have options for addressing these issues.
The Sum of All Parts: Factors of Reliability
A popular definition of reliability is “The quality of being trustworthy or of performing consistently well.” Upfront engineering is of utmost importance in developing a design that will endure its intended life cycle. On the other hand, the manufacturing of that design is just as critical.
PCB Design, Fabrication and Use from the Mil-Aero End-User Perspective
The procedures described for Rolls Royce were directly comparable with those described for MBDA, and the presenters were unanimous in re-emphasising the importance of working closely with their chosen PCB fabricators at all levels and all stages of design, qualification and production of their circuit boards.
Thermal Capabilities of Solder Masks: How High Can We Go?
This article focuses on three different coating material groups that were formulated to operate under high thermal stress and are applied at the printed circuit board manufacturing level. While used for principally different applications, these coatings have in common that they can be key to a successful thermal management concept especially in e-mobility and lighting applications.
Circuit Automation on the Ever-Evolving World of Solder Mask
In a recent conference call, I-Connect007 editorial team was joined by Circuit Automation’s Yuki Kojima, VP of engineering; Larry Lindland, sales and applications manager; and Tom Meeker, CEO, for a lively discussion about solder mask. Spoiler: It’s not all about the equipment.
Countering Solder Mask Residue Production Concerns
The solder mask application is one of the key considerations to ensure a successful application of a selective finish. The selective finish is the final chemical step of the PCB manufacturing process; this is when the panels are at their most valuable and are unfortunately not re-workable.
IMPACT on DIVSYS and NWSC Crane
I-Connect007's Patty Goldman has known DIVSYS’ Stan Bentley for many years, having met when the company was called Diversified Systems and they made circuit boards and finished products at their facility in Indianapolis. They saw each other at IMPACT recently, and of course had to have a chat.
Solder Mask: You’ve Come a Long Way, Baby!
For the July 2018 issue of PCB007 magazine, I-Connect007's editing team met with Electra Polymers’ Shaun Tibbals and Antony Earl to discuss what’s new with solder mask, including direct imaging and inkjet printing of solder mask, and what PCB manufacturers and OEMs need to know.
In With the New at Cadence
The next generation of PCB designers is coming—slowly, but surely. What will this new group of designers mean for EDA vendors like Cadence Design Systems? Andy Shaughnessy recently interviewed Dan Fernsebner, product marketing group director and a veteran EDA guy, and Bryan LaPointe, lead product engineer and representative of the younger generation. They discussed the next generation of PCB designers, some of the best ways to draw smart young people into this industry, and why the PCB designers of the future may need to have a college degree just to get an interview.
More Than a Word: Solder Mask
Do you spend time, as I do, musing on the language of PCBs? We have developed our own lexicon to convey as much by picture, as by word, what exactly we mean.
Calumet Electronics on IMPACT 2018
This year at IMPACT Washington, DC, I-Connect007's Patty Goldman sat down with Steve Vairo and Mike Kadlec of Calumet Electronics, to get their overview on the event.
Study on Application of Four-Wire and Four-Terminal Flying Probe Test Scheme
With the four-wire and four-terminal flying probe test method, voids in the holes formed in the PCB due to process differences, thin copper, and poor conduction due to residual adhesive after laser drilling of the HDI board can be detected, and the circuit board guide can be solved. With the development of multilayer, high-density PCB layout, four-wire four-terminal flying probe testing will play an increasingly important role.
Advanced Copper Plating Process for Any Layer Via Fill Applications with Thin Surface Copper
Copper-filled microvias are a key technology in HDI designs that have enabled increasing miniaturization and densification of printed circuit boards for the next generation of electronic products. Compared with standard PTHs, copper-filled vias provide greater design flexibility, improved signal performance, and can potentially help reduce layer count, thus reducing cost.
Book Review: The Introvert’s Edge
This new book by Matthew Pollard banishes the notion that only extroverts can sell. Gone is the idea that the back slapping, glad handling, joke saying, method of selling is the only way to go.
Advanced Stackup Planning with Impedance, Delay and Loss Validation
A typical PCB design usually starts with the material selection and stackup definition—the stackup planning or design exploration stage. How reliable are the data provided by the material vendors and PCB manufacturers? Can we use these data to predict trace width and spacing for the target trace impedance or to calculate delays or evaluate the loss budget?
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.
Thermal Management Materials: Easing the Decision-Making Process
There are many different types of thermally conductive materials, and choosing between them will be dictated by production requirements and application design, as well as critical performance factors that must be achieved.
Catching up with LiloTree’s Dr. Kunal Shah
Every so often, a new product comes around that promises to be a game changer and LiloTree has one of those products. Not only is it cyanide-free, it has the potential to save 40% on your entire ENIG process and is proving to be far more stable than traditional ENIG products.

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.
Book Review: The Excellence Dividend—Meeting the Tech Tide with Work That Wows and Jobs That Last
If you wait for a Tom Peters book the way some people (myself included) wait for a new Stephen King novel, then you’re in luck because Tom finally has a new book and it’s a winner. This book covers a myriad of topics in pure Tom Peters fashion. Who but Peters could bring good old meat and potatoes common sense logic to this fast-moving new world order of social media and techno faux-communications?
EIPC 50th Anniversary Conference: Alun Morgan Announcement
As the 2018 EIPC 50th Anniversary Conference came to a close in Dusseldorf, Germany, Barry Matties met with Chairman Alun Morgan to look back at how far the EIPC has come in the past 50 years and say goodbye to Michael Weinhold, longtime director and industry veteran, who announced his retirement at this year’s event.

I spoke with Michael on his 50+ years in the industry, and on behalf of everyone at I-Connect007, we wish Michael a pleasant retirement and the best going forward.
Flex Time: Why is Rigid-Flex So Expensive?
One question that I hear fairly often, particularly after an initial quotation, is “Why is rigid-flex so expensive?” In this article, I’ll share with designers the cost drivers in rigid-flex relative to standard rigid boards and flex circuits with stiffeners. A typical rigid-flex PWB will cost about seven times the cost of the same design on a hard board, and two to three times an equivalent flex circuit with stiffeners.
Book Review: Listen Up or Lose Out
There can never be enough books about the art and virtue of listening. As a sales trainer, I've learned that there is nothing more challenging than teaching people how to be quiet and listen. So, it was with great anticipation that I read this new book by the Boltons. Never has there been a better time to try to teach people, not just salespeople to turn down the devices, focus, and start intentionally listening to one another.
EIPC 50th Anniversary Conference Day 2: The Past, the Present and the Future, Pt. 2
Alun Morgan wrapped-up the proceedings, thanking delegates for their attention, speakers for sharing their knowledge and sponsors for their generous support.

Sensible Design: Protecting PCBs from Harsh, Challenging Environments
Think very carefully about the sort of environment your PCB is likely to encounter. It is easy to over-engineer a product so that it will survive the very worst of conditions, but worst conditions may only be fleeting or transient. Therefore, a resin solution with a lower temperature performance specification will often cope. Take temperature extremes, for example. Your application may experience occasional temperature spikes of up to 180°C, which you might feel deserves treatment with a special resin.
The PCB Norsemen: The Velocity of Technology— What Does It Really Mean?
Driving a car is probably one of the areas where the user comes in direct touch with the technology development. And we understand the speed when we see how fast we get new versions of smartphones and other gadgets. But in what direction are we going?
Book Review: Combo Prospecting
Tony J. Hughes has come up with a series of unique techniques combining social media and traditional methods to get to the right people with the right message using the right techniques.
RMAs: Negative Experience or Valuable Opportunity?
Non-conforming material that is sent back by the customer can easily be interpreted as a negative experience. However, if it is perceived as an opportunity to learn and support the customer it becomes a much more pleasant and satisfying endeavor.
Excerpts from Prismark’s Presentation at CPCA 2018
Prismark Partners LLC presented a detailed report at the recent CPCA meeting and show in Shanghai, China, on the challenges and opportunities for the PCB market. Part of the discussion was on 5G and is excerpted here with permission.
It’s Time to Retire ROSE Testing
Over the last two to three years, there has been considerable discussion within various IPC committees about the role of the ROSE test in today's assembly environment. The transition from predominantly water wash processes to "no clean" has meant the advent of very different flux compositions. The question has been posed as to whether the ROSE test is still a viable option for evaluating PCB and PCBA cleanliness.
PCB Material Toolbox for Today’s 3G and 4G Networks and Future High-Speed Needs in 5G
The material toolbox idea first came up when I saw the IPC appendix list for standard 1-ply stack-ups. The idea is to make a very simple bill of materials, specifications and notes, and possibly use the same prepreg/resin in the laminate and in the core.
Book Review: Do Good—Embracing Brand Citizenship to Fuel Both Purpose and Profit
The best way to get your people engaged to is give them a mission that is bigger than the company. Now more than ever, people want to believe in things and causes that matter. They want to be proud of the company they work for.
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.
5G—Generation after Generation
If you’re like me, you’ve probably heard of 5G, but you may not understand what all the fuss is about. First, 5G simply means fifth-generation mobile networks. The best way to understand what 5G is about is to understand all the other Gs, like 3G and 4G (we rarely hear about the early Gs!).
Catching up with Fineline-Global N. American CEO Eran Navick
After entering the North American marketplace just six months ago, printed circuit board provider Fineline-Global is making its mark. As the largest value-added PCB supplier in the world, Fineline prides itself on being any able to meet any challenge for any company in any part of the world. I recently had the chance to sit down with Eran Navick, the company’s North American CEO to catch up on how things are going.
May the G Force Be With You
We are about to begin the transition from the present cellular standard 4G LTE to the next generation, 5G. As in the past, most people will wonder, “What does 5G mean to me, and what is LTE anyway?” After all, if you can make your connection reliably and you can send and receive data at reasonable speeds, why should you really care?
The Institute of Circuit Technology Annual Symposium 2018
ICT technical director Bill Wilkie is well-known for choosing notable venues for Institute of Circuit Technology events, and his choice for this year’s Annual Symposium was the National Motor Museum, located in the village of Beaulieu in the heart of the New Forest, a national park in the county of Hampshire in Southern England. The region is known for its heathland, forest trails and native ponies.
Book Review: Becoming Facebook—The 10 Challenges that Defined the Company That’s Disrupting the World
Besides being an excellent history book into one of the most fascinating companies in the world, it is also a great business book. Full disclosure, I wanted to read this book because I wanted to know the Facebook story. I did not expect any of the lessons in this book to apply to me and my own small business or the small businesses that I work with, but I was wrong. The book is filled with valuable lessons that can be applied to any company, no matter the size.
APCT Moves into Rigid-Flex with Cartel, Cirtech Acquisition
When I spoke with APCT President Steve Robinson a year ago, he said he was interested in adding flex and rigid-flex capabilities, and working closely with designers and engineers. With the recent acquisition of Cartel and their subsidiary Cirtech, APCT now has a flex and rigidflex facility, along with military and aerospace certifications. At DesignCon 2018, I asked Steve to discuss these acquisitions and what they mean for APCT and their customers.
Day-to-Day: ZTE and the Potential Impending Trade War Saga
Nanya Technology, Taiwan's biggest DRAM chipmaker, will apply for a permit to provide chips to ZTE. The company said it has been notified about restrictions on shipments to ZTE, and that the ban would have limited effect on its operation. The company said on May 9 that it is preparing to apply for a permit to continue shipping chips to ZTE Corp. as export restrictions took a new turn due to a US-China trade spat.
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).
The Augmented World Expo: Go XR or Become Extinct
Now on its ninth year, the Augmented World Expo (AWE USA) is perhaps the largest event for professionals focused on providing science fiction-like abilities through XR (cross reality) and associated wearable technology.

‘Can Do’ in CAM Outsourcing: CAM Engineering—Reducing Costs
While having on-demand capacity, improved automation, and fast turn-around are critical to any front-end engineering operation, achieving those goals with a cost-effective solution is imperative. Electronics are constantly under cost-reduction pressures. Functionality, capability, and complexity increase while costs decrease.
Golden Anniversary for EIPC at the 2018 Summer Conference
June marks the start of summer, and with that, the EIPC’s annual summer conference. Highlighted by its thought-provoking presentations, social outings and factory tours, the conference continues to be valuable and productive for attendees. This year should prove no different, with EIPC set to celebrate its 50th anniversary. I spoke with EIPC Executive Director Kirsten Smit-Westenberg about what can be expected from the upcoming conference in Düsseldorf, Germany.
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.
AWE: Introducing the Augmented World Expo
The largest and most diverse event regarding the depth and breadth of technological progress and advancement is CES, which lets us get updates and allows us to focus on anything from drones to 3D additive PCB fabrication, from autonomous transportation and the degree of electronics in the newer and upcoming vehicles to the quantum computers and AI of the near future, from the forecasts found in science fiction of the ‘60s and ‘70s to the reality of 21st century technology.
Experts Discussion: What Does 5G Mean to Materials and EDA Tools?
Whether we’re ready for it or not, 5G technology is coming.

Process Control for HDI Fabrication
A subject that gets very little discussion but is essential to the HDI process is automation. That is, the control of chemical concentrations in our many PCB processes and, especially, those that have been mechanized and can change very rapidly. HDI is one of those series of processes where control is the key to high yields.
ACE’s AccuWrap Simplifies Multiple Sequential Laminations with Blind Vias
At DesignCon 2018, I spoke with James Hofer, general manager for Accurate Circuit Engineering, a quick-turn fabricator based in Santa Ana, California. James gave me a preview of AccuWrap, a new type of processing technology that lets designers reduce the amount of copper during sequential laminations while still meeting IPC specs, which should be of great interest to RF designers.
Drilling and Routing Machines: Taking Control
Once driven by hardware, the controller industry for PCB drilling is now one being driven primarily by software, so says Holger Dornau, of SIEB & MEYER. Barry Matties sat down with Holger at the CPCA show in Shanghai to discuss CNC drilling and routing machine controllers and why It's becoming more and more important for fabricators to consider.
