I recent spoke with Judy Warner, director of community engagement for Altium, about what designers should expect at both shows, and how the company can build on the success of the 2017 events going into the future.
PCB Design Challenges: A Package Designer’s Perspective
The challenges faced by the PCB designers of today are significant. If we examine the breadth of designs, we find ever-increasing data rates and more high-speed signal routing that drive additional challenges meeting signal-quality requirements, including reflection signal loss and crosstalk issues. At the same time, designers are being asked to complete designs in shorter cycle times and in smaller form factors. They must come up with new and more complex routing strategies to better control impedance and crosstalk. Manual implementation is often time-consuming and prone to layout errors.
Managing the Challenges of Flex and Rigid-Flex Design
PCB designers working with flex or rigid-flex technology face many potential risks that can derail a project and cause costly design failures. As the name implies, flex and rigid-flex designs comprise a combination of rigid and flexible board technologies made up of multiple layers of flexible circuit substrates, attached internally and/or externally to one or more rigid boards. These combinations provide flexibility for the PCB designer working on dense designs that require a specific form factor. Rigid-flex allows the PCB design team to cost-efficiently apply greater functionality to a smaller volume of space, while providing the mechanical stability required by most applications.
Chuck Bauer Discusses the Future of Packaging
When we decided to cover the future of PCB packaging, we knew we would have to interview Charles Bauer, Ph.D., owner of TechLead Corporation. Chuck recently spoke with Happy Holden, Andy Shaughnessy and Barry Matties about current trends in packaging, the need for product designers and manufacturers to communicate, and why no matter how cool the technology is, cost is still king.
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.

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.
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).
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.

So, we asked Creeden to share his insights about HDI, and how designers and manufacturers can address those issues.
Who Really Owns the PCB Layout?
In order to understand the current climate, we have to look at the division of labor that took place in electronic design about 40 years ago. The labor was divided into two processes, with the first being the design itself. This process was (and still is) owned by the electrical engineers. Though circuit design has changed, the methods for representing the circuit have not. Paul Taubman of Nine Dot Connects explains.

AltiumLive Summit—Munich, Germany, Part 2
Pete Starkey continues with his review of the AltiumLive PCB Design Summit held recently in Munich, Germany. The second day commenced with a new product launch. “Working together is hard” it read on the screen. Statistics indicated that 33% of new products were late getting to market, of which 28% were late due to insufficient collaboration, and up to 50% of potential revenue could be lost through being late to market. Then the screen read “NEXUS makes it easy!”
AltiumLive Summit—Munich, Germany, Part 1
Altium held a very successful AltiumLive PCB Design Summit in San Diego, California at the beginning of October for the benefit of their North American design community, and followed it three weeks later with a counterpart European event in Munich.

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.
Sensible Design: Thermal Management—The Heat is On
Thermal management materials are designed to prolong equipment life and reduce incidences of failure. They also maintain equipment performance parameters and reduce energy consumption by reducing operating temperatures, and minimising the risk of damage to surrounding components. Indirectly, they maintain brand reputation, as the reliability of the equipment will be very dependent upon the effectiveness of the thermal management technique used.
Whose Fault is That Bad Board?
Years ago, I held a position in an EMS company where projects were analysed before manufacturing. We found that even some of the best and most innovative circuits could not be manufactured. Why? Because the PCB designer, an electronic engineer, was not acquainted with the fabrication process. He had no idea about technological requirements necessary for electronic production. I know another designer who learned, finally, the importance of the thermal relief pad for heat restriction during reflow for a good soldering. His response? “Oh, was that what they were for? And to think I worked so much to remove them!”
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.
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.

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.
Mentor Graphics Takes Best Paper Award at DesignCon

This month we’ve been dealing with challenges related to being a great manager and a great leader. One of the biggest problems a manager faces is training—getting employees trained, and keeping them current on constantly changing technologies. I asked Leo Lambert, VP and CTO of EPTAC, what his thoughts were on the subject of leadership, and more specifically, what strategies EPTAC embraces with regard to training—both initial and ongoing.
Lightning Speed Laminates: The Blending of High-Speed Digital and High-Frequency RF
When the terms high-speed and high-frequency are mentioned, people think they describe the same issue. But in reality, they can be two very different matters. The term high-speed generally refers to digital technology which transfers data at very high rates. But the term high-frequency is typically related to radio frequency (RF), which involves analog signals moving energy at high frequencies.

Sensible Design: Conformal Coatings - Beware the Boards that ‘Bare’ All!
This month, Phil Kinner departs from his usual format of providing five essential facts about conformal coatings. Instead, he provides an account of a customer’s problem—no company names mentioned, of course—that brought into question the adhesion performance of a coating that they had been using successfully for some time.
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 Evolution of Altium: Road to a Record-Breaking Year
Chris Donato, VP of sales for Altium Americas, sat down with Judy Warner recently to discuss what he and Altium have been doing lately, where they came from (Australia) and what the future holds for Altium.

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.
New SI Techniques for Large System Performance Tuning
In this DesignCon paper, Donald Telian of SiGuys and Michael Steinberger and Barry Katz of SiSoft describe newly-developed techniques for equalization tuning and discontinuity reduction, offering additional design margin. Cost reductions are also achieved as new signal integrity techniques demonstrate performance parity, removing non-essential re-timers and PCBs layers.
Software Bytes: Having Fun With Impedance
About a year ago, I was assigned a new project: become an expert in impedance, more or less. I had no idea how much this research would bring out the nerd in me. Even if you don’t typically design controlled-impedance circuit boards, you probably will eventually. Read on!
Getting Signal Integrity Right by Design
As clock frequencies increase and active devices and interconnect traces shrink and are placed ever closer together, signal integrity becomes an increasing challenge. Today, SI is typically addressed late in the design process after the PCB layout has been completed by performing complex and time-consuming 3D extractions and simulations for high-speed lines. But with little attention being paid to SI during the layout process, simulation frequently identifies numerous SI problems.
Beyond Design: Mastering “Black Magic” with Howard Johnson’s Seminars
Dr. Howard Johnson, the world’s foremost authority on signal integrity, has recently released his High-Speed Digital Design (HSDD) Collection.

The Shaughnessy Report: The Designer Roundtable Roundup
Every year, I attend SMTA Atlanta, just across town. You have to love a local trade show. No airlines, no jet lag, and no hotels. It’s a small show; it would fit in a school gymnasium. But for me, the highpoint of SMTA Atlanta is the Designers Roundtable. This year the roundtable had 15 attendees, up from 12 last year. Two of the new attendees were under 35, which surprised all of us "graybeards."
Beyond Design: DDR3/4 Fly-by vs. T-topology Routing
JEDEC introduced fly-by topology in the DDR3 specification for the differential clock, address, command and control signals. The advantage of fly-by topology is that it supports higher-frequency operation, reduces the quantity and length of stubs and consequently improves signal integrity and timing on heavily loaded signals. Fly-by topology also reduces simultaneous switching noise (SSN) by deliberately causing flight-time skew.

Communication with your fabricator is paramount when designing flex and rigid-flex circuits.
Lightning Speed Laminates: Why Do Different Test Methods Yield Different Electrical Values?
A variety of different test methods may be used for any one electrical concern. This article will discuss the issues related to determining the dielectric constant (Dk) and dissipation factor (Df or Tan-Delta). On a data sheet, a designer may see a Dk value for a material to be 3.5, as an example. Once the designer buys the material and performs necessary evaluations, it may be found that the Dk of the material is 3.8. In some applications this difference in Dk is probably not meaningful; however, for many RF and high-speed digital applications, this difference could be very significant.
Electrical Design Challenges for Automotive PCBs
A recent article in this magazine by Monica Andrei of Continental Automotive Systems emphasized the systemic nature of an automobile and discussed the characteristics and adoption of software design tools to enable such system-level design. Recognizing that electrical challenges are part of the automotive system-level discussion, this article will present more detail on signal integrity. Future discussion is planned regarding EMI, power integrity, and thermal integrity.
McCurdy: How to Build a Successful IPC Designers Council Chapter
When Scott McCurdy made his transition from PCB fabrication to a PCB layout focus about 13 years ago, he accepted an invitation to attend our local IPC Designer’s Council. Shortly after, he was recruited to serve on the group’s steering committee. At that time, 20–25 people were regularly attending the meetings. When the chapter president moved, he asked Scott to take his place. Now, Orange County chapter meetings often draw close to 100 attendees.
Beyond Design: Plane Crazy, Part 1
A high-speed digital power distribution network (PDN) must provide a low inductance, low impedance path between all ICs on the PCB that need to communicate. In order to reduce the inductance, we must also minimize the loop area enclosed by the current flow. Obviously, the most practical way to achieve this is to use power and ground planes in a multilayer stackup. In this two-part column, I will look at the alternatives to planes, why planes are used for high-speed design, and the best combination for your application.
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.

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.
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.

Also noted were the positive responses from chemical process suppliers, and the realistic length of a product development cycle.
Effective Characteristic Impedance
Reflections can occur anytime there is an impedance mismatch on the line. Sources of mismatches are plentiful and include trace width changes, vias, stubs, reference plane changes, and even the so-called fiber weave effect. In this case, a trace can encounter a different dielectric constant depending on whether it is routed over glass or the epoxy resin in the dielectric material. In this investigation by Kirk Fabbri, it is the capacitive contribution of the different components that are of interest, and how they affect the characteristic impedance the driver sees.
