EMA Helps Ease Designers’ Supply Chain Woes

Supply chain issues are continuing to cause disruptions in our industry, though lead times have dropped from astronomical to merely troublesome. In this interview, Chris Banton, EMA Design Automation’s director of marketing, explains how Cadence’s software has evolved as designers’ needs have changed in the past few turbulent years, including providing designers with component availability data early in the process.

Q&A: The Learning Curve for Ultra HDI

For this issue on ultra HDI, we reached out to Tara Dunn at Averatek with some specific questions about how she defines UDHI, more about the company’s patented semi-additive process, and what really sets ultra HDI apart from everything else. Do designers want to learn a new technology? What about fabricators? We hope this interview answers some of those questions that you may be having about these capabilities and what it could mean for your designs.

Sunstone and I-007eBooks Launch Book on Designing for Reality

I-007eBooks is excited to announce the release of the latest title in its series for designers, The Printed Circuit Designer’s Guide to… Designing for Reality. This book covers both written and unwritten rules for how to create a realistic, manufacturable design.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

I’ve been in Washington, D.C., most of this week, attending and reporting on the IPC Advanced Packaging Symposium. You’ll see more content from me in the weeks and months to come as I sort through and highlight the varied aspects of this ground-breaking event. If you’re in this industry, advanced packaging will affect you, make no mistake about it.

Ultra HDI Primer

We recently spoke with Herb Snogren, an industry veteran and consultant with Summit Interconnect tasked with leading the company’s ultra HDI efforts. Herb is co-chair of the IPC ultra HDI subcommittee, IPC D-33-AP. In this interview, Herb discusses the current state of UHDI, how designers and fabricators can get started working in this new frontier, and why the U.S. must invest in UHDI technology now to counteract Asia’s near dominance of the UHDI segment, which has left some of our critical industries vulnerable to supply chain disruptions.

Microvias Can Be Stacked in Certain Package Densities

Summit Interconnect’s Gerry Partida recently spoke with the I-Connect007 Editorial Team about his research into root causes of weak microvias. Rather than a single manufacturing process cause, Gerry suggests that microvia reliability is the culmination of several material interactions and that contrary to popular belief, microvias can still be stacked in small, tight packaging densities. He highlights the need for simulation, as well as some of his findings that he plans to publish in a paper at IPC APEX EXPO 2023.

IPC Symposium: U.S. Must Address Critical Gaps in Advanced Packaging Needs

There is a significant capability gap in advanced substrate packaging in North America, forcing all semiconductors to be packaged in Asia and leaving North America at risk in its supply chain. This was a common theme during a two-day IPC Advanced Packaging Symposium, which launched yesterday at the Kimpton Monaco hotel in Washington, D.C.

Lessons Learned: Breaking Down the Four Types of Communication

Kelly Dack and Nolan Johnson explore the silver linings from the past two years, especially the importance of good communication. These skills are—as they have always been—key to the success of the project. But how do you define the best methods for communication? Kelly breaks down four personality types and why it’s important to recognize how one person differs from another. When you better understand how a person thinks, your level of effective communication increases exponentially.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

It’s been a busy week for I-Connect007. Managing Editor Nolan Johnson and I covered PCB West at the Santa Clara Convention Center, and, as you’ll see in my article below the place was packed. We have an article about SMTA International, scheduled for the end of October. I think the trade show season is looking good into 2023. People are done with COVID shutdowns and ready to get back to live trade shows and conferences. We’ll be in Minneapolis to bring you the latest news and technical information. We also have a news report about the European Union committing to craft its own version of America’s CHIPS Act. There’s a great interview with Dana Korf and John Strubbe about the latest innovations in materials at TUC. And columnist Paige Fiet explains why she is committed to making manufacturing “cool” again to help recruit and retain young technologists.

From the Floor at PCB West 2022

Though the organizers of PCB West had soldiered through in delivering a conference every year during the pandemic, the virtual and hybrid models just did not quite meet the requirements for a technical conference. To be fair, the limitations weren’t PCB West’s fault; the shortcomings came from the show’s virtual environments, not the host. All the more encouraging, then, that the 2022 edition of PCB West was back in bloom.

PCB West 2022 Draws Biggest Attendance in Years

There were more attendees at PCB West 2022 than I can remember in the time that it’s been held in this wing of the Santa Clara Convention Center. The show floor was busier than I’ve seen it in years. For the first couple of hours, the aisles were jammed with attendees, even on the outside aisles. You couldn’t walk without squeezing past other attendees. It was a topic of conversation all day: “How about this crowd? Wow.”

The Chip Shortage Leads to Innovation

The chip shortage is by no means over, with estimates expecting it will last into 2023. Some could see it taking even longer, such as Intel CEO Pat Gelsinger, who expects it to see shortages into 2024 due to those now impacting electronics production equipment. But if there’s any bright spot to be had, it’s that a crisis often leads to long-term solutions. In this case, it’s the increase in government funding for semiconductor production in the United States. Once the CHIPS Act proceeds, we can significantly accelerate building semiconductor fabs in the United States and work toward preventing future chip shortages that would put us back into our current situation.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

This week, our five must-reads include the IPC report on the EMS industry and a report on ICs for the automotive market. Add to that Lockheed’s highest powered DoD laser yet, IPC’s APEX keynote announcement, and—for you conference and expo junkies—a calendar of upcoming industry events. I can’t help but notice that much of our news is about, well, something new. In this case, my editor’s picks for the week capture new technology, new perspectives, new ways to communicate content, and new developments that we can expect to see in our future daily life. To borrow a phrase from the TV show “Firefly,” everything is “shiny” this week. I will be at PCB West, the IPC Advanced Packaging symposium, SMTA International, and electronica. If you see me, say hello, and share something cool about the part of the industry you’re in.

DFM 101: Final Finishes—ENEPIG and IAg

One of the biggest challenges facing PCB designers is not understanding the cost drivers in the PCB manufacturing process. This article is the latest in a series that will discuss these cost drivers (from the PCB manufacturer’s perspective) and the design decisions that will impact product reliability. Final finishes provide a surface for the component assembler to either solder, wire bond, or conductively attach a component pad or lead to a pad, hole, or area of a PCB. The other use for a final finish is to provide a known contact resistance and life cycle for connectors, keys, or switches. The primary purpose of a final finish is to create electrical and thermal continuity with a surface of the PCB.

Catching Up With John Johnson, New Director of Business Development at ASC

It’s always good to catch up with old friends, especially when you can start working together. I recently spoke with my friend John Johnson, who has joined American Standard Circuits as the director of business development. At ASC, John will be using the Averatek A-SAP process that he was previously involved with. He shares some of his background and provides insight on the best ways to use this semi-additive PCB fabrication process that opens the capability window for forming trace and space.

Some Relief, But Hold Off on the Party

To help PCB designers and design engineers get a clearer picture of the stress points in the industry, particularly from a company that deals directly with EMS providers, we reached out to CalcuQuote CEO Chintan Sutaria with a list of questions. The following Q&A explores trends in the PCB supply chain and heady advice for dealing with long lead times and counterfeit parts.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

It’s officially fall now, and in Atlanta the temperature has plummeted to the mid-80s. We’ve all bumped our air conditioners up to 74 degrees. That means it’s trade show season, and I’ve been busy looking for my suitcase. This week, we have an assortment of news about associations, education, and advocacy, as well as another installment of our Printed Electronics Roundtable. And if you’re looking for a job, you are in luck; our jobConnect007 section is chock-full of open positions at all levels in this industry.

Pack Your Bags! We’ve Got Your Trade Show Calendar Here

It’s officially fall, and that means it's time to start planning your trade show attendance. To help you make decisions about when and where to go, we’ve put together a list of industry trade shows. It has been two long years with no or few in-person trade shows, and we’ve felt it. So, now we’re back in business and ready to hit the road. Do you have a show or conference to add to our list? Let us know!

Part 2: The Printed Electronics Roundtable

We recently held a roundtable with a team of printed electronic circuit experts from companies that run the gamut: John Lee and Kevin Miller of Insulectro, Mike Wagner of Butler Technologies, Tom Bianchi of Eastprint, and John Voultos of Sheldahl Flexible Technologies. In the first part of this roundtable, the team dispelled a variety of myths surrounding PEC. In this second part of the roundtable, the participants discuss what designers and fabricators need to know to jump into printed electronics, and some of the drivers behind this growing technology.

IPC: Companies Are Intentional About Tracking Environmental and Social Risks

Leading companies in the electronics manufacturing industry are highly intentional about their environmental, social and governance (ESG) priorities, with climate change and energy use among the most closely scrutinized issues, an IPC analysis shows. As part of IPC’s ESG for Electronics initiative, IPC is interested in developing resources for members on the most common ESG methods and priorities of leading companies across the electronics value chain. In support of this, IPC has preliminarily analyzed the ESG reports of approximately a dozen companies in selected portions of the industry.

A New Sourcing Paradigm

We’ve seen many changes over the past few years, and nowhere are they more evident than in the world of sourcing components. Sourcing has become one of the biggest challenges facing PCB designers and design engineers today. Gone are the days of procuring parts from a single source, and communication between stakeholders and distributors is critical. But as we learned in a conversation with I-Connect007 columnist Kelly Dack, PCB designers can use certain layout strategies to plan for the unexpected, such as leaving extra real estate so that smaller components can be replaced by larger, readily available parts if the originals become “unobtainium.”

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

“You are the average of the five people that you spend the most time with.” This saying is attributed to Jim Rohn, and I couldn’t help thinking of that quote as I put together this week’s listings. Hear me out: 1) There are five items on our list; 2) These items zoomed to the top based on reader interest; 3) Every single one of these news items has an “association” association—IPC, iNEMI, SMTA, and NextFlex are all represented in what you, dear reader, chose to explore this last week.

Altium’s EDDI Report Tracks Components’ Availability—Today and Historically

There’s one lesson that all designers have learned over the past few years: Components might be here today and gone tomorrow, so tracking your parts is more important than ever. Any resources that help you keep tabs on your required parts are invaluable in these days of 40-week lead times. Earlier this year, Altium released one such resource: the Electronic Design to Delivery Index (EDDI) report. Assembled from millions of bytes of data gleaned from the Octopart search engineer and the Nexar platform, the monthly EDDI report provides part availability histories going back years, as well as a real-time snapshot of global inventories.

Designing Through Supply Chain Pain

Engineers are accustomed to the demanding challenges of designing for miniaturization, cost reduction, cross platform compatibility, and harsh environments. What has proven to be the most painful experience of my career (and for many of my colleagues) is the sheer lack of components from which to build our designs. Development cycles—commercial, industrial, medical, avionics—have been severely impacted, from large enterprise corporations to small design/integration companies. Awareness of the situation is the first step to understanding the underlying problems faced by today’s design engineers industry wide. Here are a few of the situations I have faced in the last year alone.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

It feels like the first day of school. It’s September, and we’re all officially back at our desks, workstations, or kitchen tables. Even Les Vacances is over. Oui, c’est vrai! But instead of facing new teachers, we have to deal with diverse market forces, supply chain issues, and technology that never seems to stop evolving. Of course, that’s what makes this industry so interesting, isn’t it?

September 2022 Issue of Design007 Magazine Available Now

Supply chain management is a dynamic situation, with a number of global forces that can create pain for PCB designers. In this issue, we speak with a variety of experts and bring you up-to-the-minute insight about designing PCBs in this ever-changing environment.

Ventec Thermal Management Book Excerpt: Chapter 1

Regarding basic principles of thermal dissipation there are three ways of dissipating energy: Conduction, convection, and radiation. The integrated metal substrate (IMS) printed circuit boards rely predominantly on heat conduction all the way through the different layers of the substrates from a hot point (the base of the component) to a cold point (the furthest surface of the metal base) and, usually, thereafter, through a dissipator.

Material Conservation: The PCB Designer's Role

During these times of supply chain uncertainty, many product developers are considering new ways to conserve materials—from laminates to components, layer reduction, and everything in between. Barry Matties and Happy Holden recently spoke with Alun Morgan, president of EIPC and technology ambassador for Ventec, about material conservation strategies for today’s PCB designers and design engineers. Alun explained why this may be the perfect time to educate PCB designers about conserving materials: When a model is broken, the people involved are much more open to new ideas.

Designing for Material Conservation Means Changing Attitudes

It makes a lot of sense: During times when the supply chain is stretched to the breaking point—and the last few years certainly qualify—what if PCB designers created boards that used fewer components and less laminate? Do PCBs still have to be 0.062" thick? Why not reduce layer count while they’re at it? Andy Shaughnessy and Nolan Johnson spoke with I-Connect007 columnist Dana Korf about the idea of designing a PCB with material conservation in mind. Is it a great new idea, or are we opening a whole new can of worms and a separate group of problems?

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

This week we have quite a variety of articles for you. There has been so much electronics industry news coming out of Washington, D.C., that it can be hard to keep track of what’s going on. So, Editor Michelle Te compiled a handy-dandy reference guide to recent legislation news, including our exclusive coverage. We need to keep an eye on these senators and representatives. They’ve been talking about the importance of our industry for the past year, but this is an election year, after all. They’ve been known to say one thing and do another.

I-Connect007 eBook Introduction: The Evolving NPI Process

Thanks to marketing and advances in technology, we have all come to expect that the electronic products we buy will be closely aligned to our individual and specific lifestyle or business requirements. This expected variability, in personal function and style, as well as regulatory compliance and a changing global economic landscape, has made designing and producing new products a challenging prospect. And, on top of the resulting “high-mix, low-volume” production cycles, increasingly more products contain electronic components in varying levels that heighten the complexity of design and manufacturing.

Design Tips for Lowering Costs of Fab and Assembly

This is the million-dollar question of every project: How can I cut the cost of the PCB? There are about a thousand answers to this question. There are a few simple guidelines that everyone can follow to reduce costs. I talk about them in my IPC CID and CID+ courses. Designers, fabricators, and assemblers talk about them in a variety of articles. Some professionals who have published some great articles on cost-saving strategies include Tara Dunn, Happy Holden, Chris Church, Kella Knack, Judy Warner, Julie Ellis, Lars Wallin, and many, many others.

Happy’s Design Tips for Material Conservation

For this issue, Happy Holden provided a range of options for designers who are seeking to conserve materials in their next design. He also offered an example of the relative cost index, or RCI, that he developed at HP exclusively for PCB design. With this RCI, designers can figure out the relative cost of a new design compared to an eight-layer through-hole board. We hope you can use this handy formula on your next design job.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

Can it be Friday already? Seems like I’ve just barely put away my Tuesday dishes. Some weeks, I wonder where my days went as they fly by so fast I hardly even realize it. As I looked back through the news for the week, it was clear why everything went so fast: There was a lot going on. The news this week had a nice feel to it. It seems like the industry is starting to gain some traction again with shows, mergers and acquisitions, and companies getting to do those “extras” that they wanted to do before the pandemic reared its ugly head. It had a little of that “back to normal” feel, even if we aren’t quite there yet. What do you think? Are we normal yet?

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

There was some good news this week, as Republicans and Democrats managed to cooperate long enough to pass the CHIPS Act. Members of the House and Senate don’t usually act until they get worried about being voted out of office, so pardon me if I’m not ready to sing “Happy Days Are Here Again” just yet. But this is still really good news; the politicians are on the record now, and we can hold them accountable.

Cadence Provides ‘Clarity’ in Design Tool

Nolan Johnson recently spoke with Brad Griffin, product marketing director for Cadence Design Systems, about Cadence’s Matrix solver technology. They discuss its use as a multi-disciplinary field solver as well as Cadence’s focus on thermal analysis and utilizing the power of the cloud.

Myths vs. Facts: The Printed Electronics Roundtable, Part 1

We recently held a roundtable with a team of printed electronic circuit experts from companies that run the gamut: John Lee and Kevin Miller of Insulectro, Mike Wagner of Butler Technologies, Tom Bianchi of Eastprint, and John Voultos of Sheldahl Flexible Technologies. In this first part of the roundtable, the participants dispel 10 common myths that have been floating around regarding printed electronic circuits (PEC). They also discuss the progress that’s been made in PEC development in just the past decade, and what the future may hold for this technology.

John Watson Wants You—to Sign Up for His PCB Design Class

I-Connect007 columnist John Watson is teaching an introductory class on PCB design at Palomar College this fall, but this is much more than a basic design class. But John has hit a slight snafu: He needs a few more students to sign up before Aug. 23, or the class will be cancelled. It’s an online class, so you don’t have to live in San Diego to attend. In this interview, John talks about the genesis for the class and its benefits.

HyperLynx: There’s an App for That

I recently spoke with Todd Westerhoff, product marketing manager for signal integrity software tools at Siemens. We discussed a new capability called HyperLynx Apps that offers a new take on traditional signal and power integrity analysis, and how that fits in with the Siemens plan to put SI and PI tools into the hands of more designers early in the design cycle.

DFM 101: Final Finishes—ENIG and ENIPIG

One of the biggest challenges facing PCB designers is not understanding the cost drivers in the PCB manufacturing process. This article is the latest in a series that will discuss these cost drivers (from the PCB manufacturer’s perspective) and the design decisions that will impact product reliability. Final finishes provide a surface for the component assembler to either solder, wire bond, or conductively attach a component pad or lead to a pad, hole, or area of a PCB.

Q4 Concerns: Hold on to Your Hats

IPC Chief Economist Shawn DuBravac has plenty to share about the state of the U.S. economy and how the electronics manufacturing industry might weather the storms of high inflation, rising interest rates, and low unemployment. It’s an interesting situation to find ourselves in as the flurry of opinion on a 2023 recession starts to take shape. Does it make sense to invest in PCB fab now? And how does the rest of the world feel about it? Shawn gets to the bottom line.

Excerpt: 'The Printed Circuit Designer’s Guide to... Thermal Management with Insulated Metal Substrates, Vol. 2'

As the second in this two-part series, The Printed Circuit Designer’s Guide to... Thermal Management with Insulated Metal Substrates, Volume 2, by Didier Mauve and Robert Art builds on the material presented in the first book by describing up-to-the-minute products and design techniques for thermal management with IMS.

New Book from I-Connect007 Examines Evolution of Electronics Industry NPI

The Electronics Industry’s Guide to… The Evolving PCB NPI Process is the first book in I-Connect007’s new The Electronics Industry’s Guide to… technical series. This valuable resource is for all segments of the electronics interconnect industry.

The Practical Side of Using EM Solvers

Electromagnetic (EM) solvers based on Maxwell’s equations have proven invaluable in the advancement of digital electronics and wireline communications. Plain and simple, electrical engineers need to know what a circuit or electrical interconnect will do when excited by a dynamic or varying signal. In the signal integrity world, an interconnect that passes a DC connectivity check can completely fail at higher frequencies. In the power integrity world, a power rail that measures the correct DC voltage could easily go into oscillation when a dynamic load is applied. Learning the basic skills to fire up an EM simulator, obtain qualitative answers in minutes, and higher fidelity answers in a few days, can be the difference between sleepless nights of product failures vs. robust designs with wide design margins.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

Our biggest news this week: I-Connect007 has been acquired by IPC. Every member of the team, including founder and Publisher Barry Matties, is included in this deal. We’ve enjoyed working closely with IPC for decades, especially at events like IPC APEX EXPO, and we have four IPC columnists writing in our magazines and newsletters. This move makes sense for both parties. It enables us to take our magazine, newsletters, and book publishing to the next level, and IPC won’t have to spend years building a media company from the ground up. It really is a win-win.

Webinar Review: Thermal Integrity of High-Performance PCB Design

Electrical and mechanical engineers may be working on the same product development teams, but they speak different languages, and they have completely different objectives. As a result, these folks almost never use the same software tools. But Cadence’s new Celsius Thermal Solver is an exception to the rule. In a new CadenceTECHTALK webinar, “How Static and Dynamic IR Drop Analysis Can Help PCB Designs and Challenges,” product manager Melika Roshandell and SerDes SI/PI engineer Karthik Mahesh Rao explain how the EE and ME can both use the Celsius Thermal Solver to achieve their disparate objectives.

IPC Acquires Media Company I-Connect007, Strengthening Relationship to Drive Growth and Innovation in the Electronics Industry

IPC, a global electronics manufacturing industry association, has acquired media company I-Connect007, a global source for news and original content serving the printed circuit design, fabrication and assembly/EMS markets.

The Great Divide in PCB Simulation Software

Today’s PCB design engineers have more layout and analysis tools at their disposal than ever before. Over the years we’ve seen layout tools become more automated, rules-driven, and more integrated. Now we even have integration between design tools from different vendors and ranging across domains, starting with basic circuit design, and spanning up to PLM and ERP integration. It really is a great time to be a designer.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

It’s always interesting how certain groups of news emerge in our most-read content. This week, reader interest seemed focused on two distinct themes: Mexico and awards. In this week’s list, we find the inaugural award recipients from iNEMI’s Project Leadership Awards. We also bring you the award recipients from the SEMI FlexTech conference held last week in San Francisco. News from Mexico includes a new Atotech facility, and an interview with IPC’s David Hernandez and Lorena Villanueva about IPC’s expanding presence in Mexico. Metcal’s new hot air rework system also got a lot of attention, with an abundance of reader interest.

The Importance of Rigid-Flex PCB Design Guidelines

I have the tendency to try to replicate the delicacies I’ve ordered at restaurants in my own kitchen. One of my latest attempts at creating restaurant-worthy dishes was a Korean pancake that’s crispy on the outside but soft on the inside. With my amateur cooking skills, it proved to be an impossible task—I could either make only a hard pancake or one that was total fluff. While I’m still struggling to figure out the trick to bringing together the different textures of a Korean pancake, I’ve had more success in bringing together the hardboard elements and flexible PCB elements of a rigid-flex PCB. Compared to making Korean pancakes, striking the right balance of flexibility and rigidity on a rigid-flex PCB is easy if you abide by rigid-flex PCB design guidelines.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

I’m getting a lot of out-of-office replies. Are you all on the beach now? It’s 91 degrees every day here in Atlanta lately, but each afternoon it rains like we’re in a horror movie, and that drops the temperature down to the subtropical arena. Still, I’ll take heat over freezing any day. Things are heating up in our industry too, as we see from my top five choices this week. First-quarter electronic design revenue is up year-on-year, but PCB revenue barely moved the needle YOY. Editor Nolan Johnson spent the week at SEMICON West and the FLEX Conference, and he brings us a review of these conferences, co-located at the Moscone Center in San Francisco. As he notes, printed electronic circuits are beginning to gain a foothold in the market.

Surveying the Land of Field Solvers

Electromagnetic field solvers have traditionally been used by a small slice of engineers—the full-time signal integrity experts—and their use has been limited to the most demanding designs. But as design speeds increase, problems requiring field solvers are becoming more mainstream and field solvers are popping up all over the place, including free or inexpensive solvers available through an internet search. Many companies are claiming that their field solvers can be used by hardware design engineers without the SI background that solvers once required.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week

In more than one conversation while discussing the industry this week, the themes have included industry turmoil, lots of business opportunities, and the urgent need to build out to meet changing demands. In fact, our July issue of PCB007 Magazine, which publishes later this month, will focus on these very topics. It’s definitely one not to be missed! These themes also emerged in this week’s top five news items as well. Top stories include an acquisition in the soldering machinery space, sales and service expansion in Mexico, industry data from SIA on semiconductor global sales data, and strong financial numbers from two China-based manufacturers. Now, with the U.S. Congress putting its focus on the PCB industry, things could really heat up. It’s going to be an interesting year.

Book Excerpt: 'An Introduction to The Printed Circuit Designer’s Guide to… Stackups'

To give readers a sample of 'The Printed Circuit Designer’s Guide to... Stackups—The Design within the Design,' by Bill Hargin, we are providing the book's introduction. He writes, "Another book about stackups? If you’re asking this question, I’d like to know the book you’re thinking of, as I was looking for it a few years back. I have a pretty good PCB signal integrity (SI) library, and I’ve only found one chapter on stackup design so far."

What Happens When You Assume?

What is design with manufacturing and what does true DWM look like in operation? In this interview, I-Connect007 columnist Dana Korf explains what it will take to achieve total communication among all the stakeholders in the PCB development cycle. He also stresses the need for everyone involved in PCB design and manufacturing to stop making assumptions, even at the risk of being labeled as “that guy” who asks too many questions.
