Electromagnetic Analysis Design Insight: Effects of Meshed Reference Planes on Interconnects
Most of the transmission lines in PCB or packaging interconnects have so-called quasi-TEM waves with the electric and magnetic fields mostly perpendicular or transverse to the propagation direction. Parameters of such transmission lines can be accurately approximated with the analysis of a single cross-section in a 2D field solver. With the cutouts in the reference plane, the waves become non-TEM and not even quasi-TEM due to the presence of the longitudinal components in the electric and magnetic fields.

The Designers Council: A Chapter Primer From the Ground Up
Thinking it might be a way to make new contacts with PCB designers in Orange County, I attended a couple of Designers Council meetings. The chapter president at that time was Paul Fleming, who asked me to be part of his steering committee because he learned that I had spent decades in fabrication. Within a few months, he had gotten a job transfer to Arizona, so he twisted my arm to take over as the chapter president. I agreed, but little did I know that this would become a major turning point in my PCB career.

Lee Ritchey Returns to AltiumLive with 32 Gbps Design Class
Lee Ritchey was one of the instructors for last year’s inaugural AltiumLive event, which drew hundreds of PCB designers. Now, Lee is back, teaching a high-speed design class at next week’s AltiumLive in San Diego. That class is sold-out, but you can catch Lee teaching the same class at the January AltiumLive event in Germany. I asked Lee to explain what he plans to cover in this course, and why PCB designers and design engineers should consider attending one of the events.
Moving From 28 Gbps NRZ to 56 Gbps PAM-4: Is it a Free Lunch?
The usual way of signaling through PCB interconnects is a two-level pulse, an encoding of 1s and 0s or bits, named NRZ (non-return-to-zero) or PAM-2 line code type. Increasing the data rate with the NRZ code type presents some obstacles. For a 28 Gbps NRZ signal, the bit time is about 35.7 ps with the main spectral lobe below 28 GHz. For a 56 Gbps NRZ signal, the bit time is about 17. 86 ps, with the main spectral lobe below 56 GHz. One can feel the problem already: Getting PCB interconnect analysis and measurements up to 56 GHz and beyond is very challenging, to say the least.
Judy Warner: AltiumLive’s Second Year to Be Even Better Than First
Last year, Altium launched its AltiumLive event with shows in San Diego and Munich, Germany. This year, the event has expanded to include an extra day of classes.

Special thanks and good wishes to Michael Weinhold for his enormous contribution over the years, and to Kirsten Smit-Westenberg and Carol Pelzers for their calm and professional organisation and management of another superb event.
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.
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.
APCT Moves into Rigid-Flex with Cartel, Cirtech Acquisition

Patty Goldman sat in on some subcommittee meetings, including one on laminates, where she met up with Ventec COO Mark Goodwin for a discussion on thermal management from a laminate supplier’s perspective.
The Impact of HDI on PCB Power Distribution
A key aspect of HDI technology is the use of microvias. For reference, the IPC HDI Design Committee has identified microvias as any hole equal to or less than 150 microns. Multiple types of HDI stack-ups associated with blind and buried microvias can be used to meet the density and cost requirements for today’s products. Design teams should develop stack-ups in conjunction with the fabricator to minimize cost and meet signal integrity requirements.

A Guide to IPC Survey and Report Season
IPC Director of Market Research Sharon Starr found time to discuss the recently conducted and published surveys and research reports and a few others still in the works. These reports are free to survey participants, which is certainly a great incentive for taking the time to complete them. (Hint: That’s a call to action for those of you sitting on the sidelines.)
PCB Signal Integrity Optimization Using X-ray Metrology
It happens again. A new backbone router/switch build or a line card upgrade is approaching completion when something goes wrong. The system won’t operate at the targeted data rate. Deadlines are looming and the root cause of the problem is buried somewhere in a big rack of electronic components.
Enough Blame to Go Around
The idea for this article began a few months ago when The PCB Design Magazine conducted a reader survey regarding the topic “Whose Fault is that Bad Board?” After some thought, I submitted my answers. After all, I must have some kind of input after over 25 years of PCB design. But still, whose fault is that bad board? OK, I know what you’re thinking: Don’t go there. We designers make mistakes too.

Design Strategies for Success—and Profit
In today’s economic environment, making money on a project is getting more and more challenging. Those years when businesses like mine were practically printing money are long gone. If you are under 30 years old, you probably do not have this point of reference; it’s been one downturn after another for your entire adult life. But for us older folks, times were really good back then. So, what happened? You happened, as well as a million others like you. In other words, the market is a little cramped now and much more competitive, which dilutes our profit per project.
Brooks' Bits: How Many Vias Does It Take To…?
During 2015, I enjoyed a very productive collaboration with Dr. Johannes Adam, from Leimen, Germany. This resulted in several papers, but one in particular is relevant for this column, “Via Currents and Temperatures.” In that paper, we used a simulation tool, thermal risk management, developed by Dr. Adam, to simulate current flowing through a via and then determine the temperature of the via. Read on to find out how our results contradicted conventional wisdom.

Beyond Design: Faster than a Speeding Bullet
In optical communications, electrons don’t carry the signal—photons do. And we all know that photons travel at the speed of light. So surely, optical fibers must transmit information much faster than copper wires or traces on a multilayer PCB? Actually, photons and electrons transmit data at the same speed. The limiting factor is the relative permittivity (dielectric constant) of the medium in which the signal propagates.
Designers Notebook: Flexible and Rigid-Flex Circuit Design Principles, Part 3

You may have seen Anne Marie Mulvihill at the Design Forum during IPC APEX EXPO, rounding up speakers with a sarcastic comment or two. As PCB design program manager for IPC, Anne Marie makes the design train run on time. When I told Anne Marie that we were covering the Designers Council for this issue, she jumped at the chance to help us.
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.
The Shaughnessy Report: Are You Drowning in Data?
Data management was so much simpler during the days of Mylar and Bishop Graphics tape. Data was handwritten. All you had to do was keep track of your paperwork and you were golden. Now, you’re all much more productive, but you have data coming out of your ears; slowly but surely, incrementally, data has become much more complicated. How do designers and engineers wind up managing all of this data? With kluged-together processes and software tools, and the occasional handwritten notes.
IPC: Connecting Electronics Industries
John Mitchell, president and CEO of IPC—Association Connecting Electronics Industries, provides the basic overview of the association—its goals and basic mission, activities, and how it best serves its membership.

The Associations Issue
Well, it’s the end of the year. How did that happen? It really is true that every year goes by a little faster. You young whippersnappers out there won’t know what I’m talking about, but just you wait and see. We changed it up for our December issues this year. Instead of doing a year-end review, we decided to devote this month to our associations and trade organizations—at least some, because when you start poking around, you will find there are scads of them.
Pulsonix Poised to Take More EDA Market Share

The Gerber Guide, Chapter 3: The PCB Profile
The profile defines a simple region in the 2D plane. The proper way to do this is to specify a closed contour: The inside of the contour is the PCB, and the outside is not. It is that simple. Note that such a simple region is solid, without holes. By definition then, a profile cannot have holes intentionally placed within it. These are superfluous and represent an unnecessary and complicated duplication given that drill holes are well defined in the drill/rout file. One can view cut-outs in a PCB as still part of the PCB, just as much as the drill holes are.
Speeding up the Design Cycle: 10 Things to Remember
Many people understand the value of a PCB, but do not understand the best way to interact with PCB manufacturers. Poor planning and communication with fabricators slows down the design cycle and increases overall costs for your project. In this column, Mark Thompson streamline the design cycle through fabrication. Following my tips will minimize the need for future revisions and ensure you get quality boards on time.
Accelerating the Design Cycle : Moving from Discipline-Centric to Product-Centric Design
Today, the design process in most cases fans out from the requirements as defined by marketing into multiple independent design threads that converge at the prototype. There is usually no systematic method for these different disciplines to communicate their work to the other disciplines. This lack of communication often leads to conflicting design decisions, such as when an electrical engineer or purchaser selects a component without having any way of knowing that it interferes with the enclosure. Extra design turns are often needed to resolve these conflicts at the prototype stage.
The Readers Speak: Tips on Accelerating your Design Cycle
This month, in addition to publishing feature articles by well-known experts in the field, we decided to collect feedback from the readers—PCB designers and engineers working in the trenches each day. We asked our readers to provide their favorite tips, tricks, and techniques for speeding up the PCB design cycle. Here are 10 tips for cutting your design time, courtesy of designers just like you.
The Material Witness: Nonwoven Aramid Reinforcement is Back
In the 1st century AD, there was significant debate among Jewish theologians as to whether resurrection was possible. PCB designers in the early 21st century have had a similar concern about future availability of 85NT nonwoven aramid laminate and prepreg. The stakes may be somewhat less critical, but the future of a wide variety of programs designed around the properties of Thermount have been hanging in the balance.
Insulectro Hosts Silicon Valley Designers Council Meeting
On October 15, about 25 people gathered for the IPC Designers Council Silicon Valley Chapter meeting at Insulectro's Mountain View facility. Carl Schattke, senior PCB design engineer at Tesla, was the main speaker. His presentation covered a variety of facets of PCB design, from shadowing to the location of component based on weight and surface finishes.
Leo Lambert on EPTAC's Customized Training Plans
Andy Shaughnessy interviewed Leo Lambert, vice president and technical director of EPTAC, at SMTA International. Leo Lambert, vice president and technical director of EPTAC, explains how the New Hampshire-based company continues to provide customized training and IPC certification offerings, including its IPC Certified Interconnect Designer (CID) and CID+ classes.
The Gerber Guide, Chapter 2
Never mirror or flip layers! All layers must be viewed from the top of the PCB, which means that the text must be readable on the top layer and mirrored on the bottom layer. Alas, sometimes, in a mistaken attempt to be helpful, designers flip layers because they must anyway be mirrored on the photoplotter. This could be helpful in a world where the designer's files are used directly in fabrication, but these data layers are actually input for the CAM system.
Physics of Failure Durability Simulations for Automotive Electronics
Automotive electronics systems are becoming increasing complex and essential for the proper, safe operation of cars and trucks. Vehicle controls for basic operation and safety functions are increasingly being implemented by electronic modules. The ability of these electronic systems to function reliably is becoming a greater aspect of vehicle safety as was dramatically demonstrated by the 2009–2011 recall of over 9 million Toyota vehicles for unintended acceleration issues.
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.
Failure May Not Be an Option, but Sometimes It's a Reality
I’ve had mechanical engineers question why we are bothering with circuit boards instead of designing the circuitry into the plastic housing of the device. I’ve had manufacturing engineers demand that I shelve the electrical considerations in order to meet manufacturing requirements, and electrical engineers who could care less if the product could actually be built. I’ve had engineers hover over my shoulder watching each and every stroke of the mouse that I make, and others who are never available for important questions which ultimately brought the whole project to a grinding halt.
Failure Mode: Hole Wall Pullaway
This column is based on my experience in test reliability of interconnect stress test (IST) coupons. I am addressing HWPA that features moderate to severe outgassing. There may be HWPA due to thermal stressing of the board without any significant outgassing, but this type of HWPA is subtle, and it presents as a dark line between the plating and the dielectric of the hole wall. This type of HWPA is rarely detected.
Material Witness: Using Scaled Flow Data
Resin systems whose density is not very near 1.35 do not quite fit into the official IPC test method because all the stack weight data used assumes epoxy resin of a standard 1.35 density. Any resin whose density varies from that value requires a new set of calculated weights for various stack-ups in order to provide precise data. This is especially true of filled systems whose resin density now includes a ceramic component as well as the organic resins themselves and may have densities higher than standard.
Beyond Design: Stackup Planning, Part 3
Following on from the first Stackup Planning columns, this month’s Part 3 will look at higher layer-count stackups. The four- and six-layer configurations are not the best choice for high-speed design. In particular, each signal layer should be adjacent to, and closely coupled to, an uninterrupted reference plane, which creates a clear return path and eliminates broadside crosstalk. As the layer count increases, these rules become easier to implement but decisions regarding return current paths become more challenging.
Karel Tavernier: The Gerber Guide
It is possible to fabricate PCBs from the fabrication data sets currently being used—it's being done innumerable times every day. But is it being done in an efficient, reliable, automated and standardized manner? At this moment in time, the honest answer is no, because there is plenty of room for improvement in the way in which PCB fabrication data is currently transferred from design to fabrication.
Supply Chain Challenges and Opportunities
Let’s start by defining exactly what a supply chain is. It’s not a nautical term for an anchor chain, or a dynamic part of a chainsaw that never runs out of chain. No, it’s a key term used in the organization of resources which may form a system between entities. Now this sounds a little closer to something that may be utilized in producing an electronic end-item, in our case, a printed circuit board.
IPC-A-610: What's New With Rev F?
Why are new revisions created anyway? Can’t IPC just issue updates to the existing revision? Who defines what the changes are going to be and who approves of those changes? Why can’t they make changes for all the new technologies available? And the best question of all: Why does my product have some conditions that are not covered in the documents and specifications? Leo Lambert explains.
The Past, Present, and Future of IPC-A-610
To understand the ultimate power of IPC-A-610, you need to first understand what is at the core of this standard. IPC-A-610 is a collection of visual quality acceptability requirements for electronic assemblies. It is utilized as a post-assembly acceptance standard to ensure that electronic assemblies meet acceptance requirements.
EIPC Summer Conference: Day 2

Electronic Design Training Crucial to Industry Growth
In the UK, the electronics industry contributes over £80 billion (approximately US$120 million) to the economy, representing 5.4% of UK GDP, employing over 850,000 people. There is, however, in many countries, a growing concern around labour shortages within the electronics industry, with worries over appropriate workforce skill levels growing.
The Composite Properties of Rigid vs. Multilayer PCBs
Most materials systems used in PWBs (aka PCBs) are composites of resins, fabric substrates and metal cladding. Each of these components has its own unique electrical and mechanical properties that contribute to the final characteristics of the finished laminates, prepregs and fabricated multilayer boards (MLBs). In most cases variables such as glass style and resin content have offsetting impacts on physical vs. electrical properties. Chet Guiles explains.
Polar Talks Impedance Control and Insertion Loss Testing

New Embedded Component Standard Finalized
Solberg Technical Consulting's Vern Solberg talks to I-Connect007 about the recently launched standard, the IPC-7092, which focuses on embedded component technology. According to Solberg, this new standard took the earlier standards involved with passive devices, and combined it with standards on newer technologies using active devices, to help form components that can be manufactured and placed on layers within the PCB.
iNEMI Managing Director: New, Disruptive Technology on the Horizon
Dr. Haley Fu, managing director of Asia Pacific for iNEMI, and Publisher Barry Matties spoke recently. Fu gave her overview of the last eight years with iNEMI along with her opinion of what the most significant changes have been, globally and for the Asia market in particular. She predicts that in the future, the PCB will probably adopt optical architectures instead of copper, because using copper for the trace means that the land space and the property will not satisfy the future high-speed data transport rate.
IPC Plating Sub-committee 4-14: Surface Finish Specifications
IPC specifications are reference documents to be called out by designers and OEMs. Designers may take exception with one or more items in the specification to ensure that the product meets the requirements of its intended use. The acronym AAUBUS (as agreed upon between user and supplier) is part of any specification. Specifications are consensus documents. They are agreed upon by a panel of interested industry participants composed of suppliers, manufacturers, assembly houses (CMs) and end-users. The IPC Plating Sub-committee 4-14 is no exception.
Material Witness: How About that Technical Roadmap!
You may remember the movie "What About Bob?" If you do, you may recall the scene in which Bob (Bill Murray) confronts his psychiatrist (Richard Dreyfuss) and emotes, “I need! I need! I need! Gimme! Gimme! Gimme!” As I thought recently about some of the drivers that IPC and others have incorporated into their technical roadmaps, I feel a bit like that befuddled psychiatrist.
IPC Validation Services 2014
Guest Editor Judy Warner talks with IPC's Director of Validation Services, Randy Cherry. Randy has been busy since launching IPC's Validation Services a year ago, with 16 QML audits completed and rapidly growing interest shown at this year's show.
