Stitching Capacitor: Crosstalk Mitigation for Return Path Discontinuity

When the return path is broken due to the switching of reference planes with different potential, e.g., from ground to power or vice versa after layer transition on PCB, the return current might detour and propagate on a longer path, which causes a rise in loop inductance. This might lead to the sharing of a common return path by different signals that pose a high risk of interference among the signals due to higher mutual inductance. This interference results in signal crosstalk. To mitigate the crosstalk due to return path discontinuity (RPD), stitching capacitors are mounted on the PCB to serve as a bridge between the two reference planes of interest on different PCB layers.

Wild River, eSilicon, and Samtec Team up for 112-Gbps Test Vehicle

Impact of Serpentine Routing on Multi-gigabit Signal Transmission

Serpentine is a technique to minimize skew or misalignment of differential pairs. The number of segments and intra-pair spacing of serpentining impacts the high-speed signal transmission. As the intra-pair gap is enlarged for serpentining, the characteristic impedance of the PCB trace in differential mode will rise. This leads to impedance discontinuity, signal reflection, and ultimately, attenuation. The signal attenuation is heavily dependent on the number of segments and intra-pair spacing of the serpentine.

Life Beyond 10 Gbps: Localize or Fail!

Ideally, all interconnects should look like uniform transmission lines (or wave-guiding structures) with the specified characteristic impedance. In reality, an interconnect link is typically composed of transmission lines of different types (microstrip, strip, coplanar, coaxial, etc.) and transitions between them such as vias, connectors, breakouts and so on. Transmission lines may be coupled to each other that cause crosstalk. The transitions may reflect and radiate energy due to discontinuities in signal and reference conductors. The crosstalk, reflections and radiation cause unwanted and sometime unpredictable signal degradation.

Achieving Minimal Crosstalk in Multi-board Interconnect

In an electronic system, the signal transmission exists in a closed-loop form. The forward current propagates from transmitter to receiver through the signal trace. On the other hand, for a single PCB, the return current travels backward from receiver to transmitter through the ground plane closest to the signal trace. Meanwhile, for multi-board interconnect (e.g., connectivity through flex or ribbon cable), the return current travels back to the transmitter through the ground or return wire, preferably as close as possible to the signal wire. The path of forward current and return current forms a loop inductance.

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.

The Impact of PCB Dielectric Thickness on Signal Crosstalk

Crosstalk is an unintentional electromagnetic (EM) field coupling between transmission lines on a PCB. This phenomenon becomes a major culprit in signal integrity (SI), contributing to the rise of bit error occurrence in data communications and electromagnetic interference (EMI). With the existence of mutual inductance and capacitance between two adjacent transmission lines on a PCB, crosstalk has become more severe due to the shorter signal rise/fall times at today’s higher data speed rates.

But multi-board designs have become almost ubiquitous over the past decade, and EDA software companies are working to improve and simplify the multi-board design process. Editors Andy Shaughnessy and Stephen Las Marias spoke with Ben Jordan, director of product and persona marketing for Altium, about the company’s multi-board design tools, the challenges that customers face, and the numerous trade-offs that designers must contend with while performing multi-board design.

Achieving Optimum Signal Integrity During Layer Transition on High-Speed PCBs

In electronic systems, signal transmission exists in a closed-loop form. The forward current propagates from transmitter to receiver through the signal trace. Meanwhile, the return current travels backward from receiver to transmitter through the power or ground plane directly underneath the signal trace that serves as the reference or return path. The path of forward current and return current forms a loop inductance. It is important to route the high-speed signal on a continuous reference plane so that the return current can propagate on the desired path beneath the signal trace.

I recently caught up with Mike and asked him to give us his views on the state of thermal management, as well as the tools and standards related to thermal design.

Streamlining Thermal Design of PCBs

When designing a PCB, thermal issues are often locked in at the point of selecting and laying out the chip package for the board. After that, only remedial actions are possible if the components are running too hot. Assumptions made about the uniformity of the airflow in these early design stages can mean a disaster for the commercial viability of a PCB if those assumptions are incorrect. A different approach is needed to improve reliability and to optimize board performance. Dr. John Parry of Mentor explains.

Mentor White Paper: Characteristic vs. Instantaneous Impedance

Successful signal integrity analysis depends on a fundamental concept: impedance. Without a thorough understanding of the impedance values that a signal encounters along the way, designers cannot maintain good signal quality from source to receiver.

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.

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.

RTW SMTAI: Judy Warner Discusses AltiumLive: 2017 and Her New Role

AltiumLive features Happy Holden and Charles Pfeil, as well as a robot design challenge and battle.

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!”

Orange Co. Designers Council Meeting Focuses on Embedded Passives

On July 19, the Orange County Chapter of the IPC Designer’s Council hosted a lunch-and-learn meeting in Tustin to discuss the benefits of embedded passives. Approximately 40 people were in attendance, which was lighter turnout than usual, most likely because of summer vacations. But the crowd was an enthusiastic one, as usual. The first speaker was Bruce Mahler of Ohmega Technologies, followed by Jin Hyun-Hwang of Dupont.

PCB Designers Notebook: Embedding Components, Part 2

Technology and processes for embedding capacitor and inductor elements rely on several unique methodologies. Regarding providing capacitor functions, IPC-4821 defines two methodologies for forming capacitor elements within the PCB structure: laminate-based (copper-dielectric-copper) or planar process and non-laminate process using deposited dielectric materials.

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.

Embedded Technology: A Useful Tool in Freedom CAD’s Toolbox

Freedom CAD has been designing and fabricating boards with embedded technology for years, and doing some pretty innovative work along the way. I asked Scott McCurdy, Freedom CAD’s director of sales and marketing, to share some details about their embedded processes, as well as the challenges and opportunities that embedded technology offers.

Launching a New PCB Design Curriculum in Serbia

Let me share with you an experience that I remember from my college days. When I was a student, I had a professor who was too proud of the fact that she was an academic. “You don’t need to know how to manually solder electrical parts or how to design printed circuit boards,” she lectured. “It is important that you understand the formula for charge carrier currents in a p-n junction.” I started working as an R&D engineer for a Swiss company that developed and manufactured instruments for measuring magnetic fields and electrical currents. And nobody ever asked me about charge carriers in p-n junctions.

Technology Enabler Highlights Benefits of Having Design Services for an EMS Firm

At the 14th Philippine Semiconductor and Electronics Convention and Exhibition (PSECE) held last week in Manila, Robin Ramiso, design and development manager at Technology Enabler, discusses their activities, and the benefits of having a design services team for an EMS company with I-Connect007 Managing Editor Stephen Las Marias.

The event, a convention for the Romanian electronic packaging community, included a series of actions designed to draw smart young students to the electronics industry, which is clearly growing. Participants had only four hours to create this PCB design, which was generated by a team of professionals from Continental Automotive Romania Timisoara.

PCB Design in the Age of IoT

From the early days of printed circuit boards, the electronics industry has made huge strides in board materials, copper printing methods, miniaturization, rigid-flex, ELIC, EDA, and much more. Many of the devices we use in our homes, our vehicles, and in our workplaces would not be possible without this continuous evolution of PCB design and technology. And yet in 2017, we are poised to shift from evolution to revolution, driven by the idea of the Internet of Things.

'Flexdude' Tom Woznicki Celebrates Company’s 25th Anniversary

Twenty-five years ago, Tom “Flexdude” Woznicki got laid off. A lot of people did, back during the mini-recession that helped bring Bill Clinton into the White House. So, he launched his own flex circuit design bureau and never looked back. Since then, he’s designed flex circuitry for everything under the sun, including the Mars Rover; the flex circuits he designed are visible in many of the Rover photos. I ran into Tom at DesignCon 2017 and we discussed the benefits of flex circuits, the expansion of the flex market, and his company’s first quarter-century in operation.

During the recent CPCA Show in Shanghai, Editor Stephen Las Marias and Polar Instruments (China) Assistant Manager Simon Chan discussed the opportunities and challenges for Polar's customers in the Asia-Pacific region, as well as the current state of the high-speed PCB market in China.

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.

Perpetual or Subscription EDA Tool Licenses? That is the Question

After I began working at Altium, I started learning all I could about PCB design software licensing. I wondered about the pros and cons of perpetual vs. subscription licenses. I wanted to learn firsthand from PCB designers what kind of benefits they received and challenges they faced as a result of how EDA companies offered design tools. I reached out to a variety of sources to get a broad slice of insight into this evolving issue, and thus began my trip down the EDA licensing software rabbit hole.

Mentor Graphics Takes Best Paper Award at DesignCon

At DesignCon, I met with Dave Kohlmeier, senior product line director for Mentor Graphics. We discussed their Best Paper award and DesignCon sessions such as the Signal Integrity Boot Camp, as well as the new rigid-flex capabilities found in the HypeLynx suite.

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.

Exciting New Technology: Thermal Risk Management

Two years ago I entered into a collaboration with Dr. Johannes Adam, from Leimen Germany. Johannes has written a software simulation tool called Thermal Risk Management (TRM). We used it to look at the thermal characteristics of PCB traces under a variety of conditions, and it is hard for me to contain my excitement and enthusiasm for what it does and what we learned about traces using it. Our collaboration resulted in the publication of numerous articles and a book. In this article, I’ll talk about some of the capabilities of TRM that really caught my attention.

Kelly Dack and Mike Creeden: Are We in a PCB Design Renaissance?

Technical Editor Kelly Dack and San Diego PCB founder Mike Creeden discuss some of the trends they're seeing in the PCB design community, including greater numbers of young people becoming designers and more EEs doing design work. They also focus on IPC's training and designer certification efforts, and the need for designers to get out of the office and visit a board shop once in a while.

Selling PCB Design Services in a First-World Country

As the business operations manager for Better Boards Inc., I see our company at the focal point for consolidation: a gathering of skilled board designers to create a center of excellence. It is at this point that we have the critical problem facing a PCB design services company: How do we effectively sell these services back to the companies that cast off their own skilled employees? How do we sell PCB design services into small companies that can barely afford the one overworked electrical engineer that they hired last year?
