Manufacturing Institutes Can Boost the Nation

In his most recent State of the Union address, President Obama highlighted a remarkable trend of recent years: the turnaround in many corners of America’s manufacturing sector. Nearly 900,000 new jobs have been created by U.S. manufacturers in the last six years.


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

This installment of "Designers Notebook" will focus on methods for specifying base materials, and also address copper foil variations and fabrication documentation. It is important to research the various products in order to choose the one that best meets the design requirements.

Catching up With Tom Hausherr of PCB Libraries

When fate placed Tom Hausherr and I at PCB West, we made sure to carve out some time together. Tom agreed to have a long breakfast with me so I could learn more about the challenges related to component libraries and how his company addresses these issues. So, pull up a chair and join us for a chat.

Designers Notebook: Flex and Rigid-Flex Circuit Design Principles, Part 2

In this installment of "Designers Notebook," Vern Solberg discusses supplier assessment, planning of the flexible circuit outline, and various circuit routing principles. Communication between designer and fabricator is paramount, as well as an understanding of IPC-2223, which sets the specific requirements for the design of flex circuits.

Justifying the Need to Outsource Design Work

Mehul Dave and H.D. Shreenivasa of Entelechy Global discuss the many benefits of outsourcing and why it should not be thought of as a four-letter word. They also talk about the huge gap between design and manufacturing, and how their company can help customers address that issue.

New Year, New Outlook for the Electronics Manufacturing Industry

As an advocate for the electronics manufacturing industry, my job is to educate and encourage policymakers to create a favorable legislative and regulatory environment for advanced manufacturing to grow and succeed. From that perspective, I think we should be proud of the significant progress we made in several areas in 2015.

Designers Notebook: Flex and Rigid-Flex Circuit Design Principles, Part 1

In his new Designers Notebook column, Verb Solberg discusses primary flex circuit structures, proper design for operating environment, and base material selection. The design guidelines for flexible circuits, although similar to those for rigid circuits, have distinctive differences that are influenced by specific applications and the intended operating use environments. Communication with your fabricator is paramount when designing flex and rigid-flex circuits.

IPC Designers Council Viewpoint: Gary Ferrari

As co-founder and longtime executive director of the Designers Council, Gary Ferrari has dedicated a big part of his career to PCB design. After decades of service, he was inducted into the IPC Hall of Fame at IPC APEX EXPO this year. I caught up with Gary and asked him to fill us in on the creation of the Designers Council, and some of the changes he’s seen in the last 24 years.

IPC Designers Council Viewpoint: Mike Creeden

When covering the IPC Designers Council, one quickly learns that it’s the volunteers who make the train run on time. San Diego PCB CEO Mike Creeden, CID+, is one such volunteer, and as a member of the Designers Council’s Executive Board, he was a must-have for this issue. I tracked him down and asked him to give us a rundown of his involvement with the DC, and to explain why designers might want to get involved with their local DC chapters.

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.


IPC Designers Council: Serving PCB Designers for Almost 25 Years

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. He also provides a snapshot of how IPC promotes technology development in the industry through standardization.

Rogers Scales up Production and Integrates Arlon Range

Editor Pete Starkey interviews Rogers European Sales Manager John Hendricks at productronica 2015. Hendricks updates us on Rogers’ acquisition of Arlon, and explains how the Arlon products are complementary to Rogers’ existing materials.

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

Publisher Barry Matties met with Bob Williams, managing director and co-owner of Pulsonix, and Sales and Marketing Manager Tyrone Stephens to discuss the challenges facing the EDA tool market, and how they’re establishing this company in the global design tool marketplace.

Navigating the Global Materials Supply Chain: A Roundtable Discussion

At SMTAI recently, I-Connect007's Andy Shaughnessy sat down for a roundtable discussion with some key players from the materials side of the supply chain. Participants included two executives from Ventec: Mark Goodwin, COO USA and Europe for Ventec International Group; and Jack Pattie, president of Ventec USA. Also participating in the roundtable were Schoeller Electronics CEO Michael Keuthen and Bob Willis, from the National Physics Laboratory (NPL).

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

Refreshed after an excellent conference dinner, and for most, a good night’s sleep, delegates returned for the second day of the EIPC Summer Conference in Berlin, continuing the theme of improving profitability through technical leadership and innovation to meet future market requirements, with sessions on materials and processes for high performance PCBs and advanced material testing strategies to meet OEM and ODM needs.

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.

Material Witness: Low-Flow Prepregs–Defining the Process

Let’s try to define “low flow” in terms that will make sense to both suppliers and users of the products. A low-flow prepreg is a prepreg that flows sufficiently to wet out and adhere to bonding surfaces and to fill inner layer copper details, but does not flow so much as to fill in cut-out areas in a heat sink or run unevenly out of the interface between rigid and flexible elements of a rigid-flex PWB.

Japan’s Thermosetting Plastics Association Represents at IPC APEX EXPO 2015

At the International Reception, held opening night of IPC APEX EXPO 2015, I-Connect Technical Editor Pete Starkey made the rounds and found some visitors from Japan, namely, Kazutaka Masaoka, from Thermosetting Plastics Association (JTPIA).
