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

The summer is heating up, and our news this week is on fire, literally. Eltek has resumed making deliveries after a fire at their facility in Petach-Tikva, Israel. There’s never a dull moment in this industry. And we have some good news: EIPC’s conferences are now live events again, and Editor Pete Starkey is back in the saddle, bringing us a review of the two-day conference. I know Pete was getting tired of sitting around his house and watching these events on video.

Rambus Driving a CXL Memory Option

In this interview with Arjun Bangre, director of product for high-speed interface IPs for PCI Express and CXL at Rambus, the discussion revolves around new developments in CXL, PCI Express, and interoperable IP solutions that Rambus has developed.

Master the Art of Communication With Manufacturers

As mentioned in the May issue of Design007 Magazine, design is performed, at times, in a vacuum. But it doesn’t have to be that way. Whenever circumstances allow, design should be performed by communicating with all stakeholders throughout the design process, hence the emphasis on the word with in DWM. Communication can occur through personal correspondence such as email and voice conversations or through more formal design meetings—in person or through videoconferencing. No matter which means of communication you prefer, it’s important to communicate early and often with stakeholders involved in the downstream processes as you bring your project to realization.

EIPC Summer Conference 2022: Day 2 Review

Örebro, Sweden on June 15 brought a bright and early start to Day 2 of the EIPC Summer Conference for those who had enjoyed the previous evening’s networking dinner, but had resisted the temptation to over-indulge or to carry on their long-awaited catch-up conversations with old friends into the small hours. All but a few were in their seats for 9 a.m., awake and attentive for Session 4 of the conference, on the theme of new process technologies, moderated by Martyn Gaudion, CEO of Polar Instruments.

The Survey Said: Why Don’t You Know Your Fabricator?

When we want to find out what challenges our readers are facing, we just ask. And they don’t mind sharing—the good, the bad, and the ugly. In a recent survey, we asked our PCB designer readers, “Why don’t you know who is going to manufacture your boards?” Here are some of more interesting replies we received, edited slightly for clarity. Do you see yourself in these replies?

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

We’re still not officially into summer yet, but Atlanta is bringing the heat, baby! It’s hit 97 degrees a few times this week, and I now have a fan aimed right at my face. At least it’s nice and humid too. I’m glad I don’t wear make-up. And it’s been a hot week in the circuit board community. This week, Eltek reported a fire at a board shop in Israel, and Flex committed to building a 145,000-square-foor facility in Jalisco, Mexico to serve the electric and autonomous vehicle segment.

Producing Diverse Designs in Concert With Manufacturing

There is a new acronym bubbling up in the design world: DWM, which stands for “design with manufacturing.” Why is this different than design for manufacturing, or DFM? With DWM, the emphasis is on integration between the design team and the manufacturers during the design process. DWM is much more than that. We are tasked with producing designs that meet various technical requirements, yet are cost-effective and manufacturable. We provide this service to hundreds of customers who have varying degrees of processes, tools, and manufacturing partners. Given this diversity, we have recognized the importance of designing with manufacturing to achieve the product development goals of manufacturability and technical excellence.

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

The big news in the industry this week was the new bill introduced to the U.S. Congress in support of the PCB manufacturing industry. The Supporting American Printed Circuit Boards Act of 2022, which was introduced by Reps. Anna Eshoo (D-CA) and Blake Moore (R-UT), incentivizes “purchases of domestically produced PCBs as well as industry investments in factories, equipment, workforce training, and research and development.” The bill is a PCB-oriented complement to the semiconductor-oriented CHIPS Act of 2021.

Designing in a Vacuum Q&A: Mark Thompson

I-Connect007 Columnist Mark Thompson of Out of the Box Manufacturing has been in CAM engineering for decades, and he’s also worked as a PCB designer, so we knew he would have a few things to say about working in a vacuum. As he explains, the designer isn’t the only stakeholder in the process who feels like he’s working inside the dust bag of a Hoover upright.

Designing in a Vacuum Q&A: Carl Schattke

Not long ago, I caught up with Carl Schattke, CEO of PCB Product Development LLC and a longtime PCB designer, for his thoughts on “designing in a vacuum.” As Carl points out, if you follow PCB design best practices, knowing the identity of your fabricator is not a “must-have.” He also offers some communication tips for discovering the information you do need, including one old-fashioned technique—just asking for it.

Tips for Designing in—and Escaping From—the Vacuum

We asked Monsoon Solutions VP of Engineering Jen Kolar if she had any thoughts on “designing in a vacuum,” and her response was, “Absolutely!” In this wide-ranging discussion, Jen and Senior PCB Engineer and Director of Designer Development Cory Grunwald share some tips and techniques for designing PCBs in a vacuum, and a few methods for getting out of the Hoover’s dust bag. As Cory points out, “In the end, the communication is going to happen anyway. It’s just a matter of whether it happens at the end or in the beginning.”

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

It certainly seems that our times continue to be interesting, don’t they? Just how many different flavors of supply chain disruption can we come up with? Investment on the supply side needs to increase, but the size of the labor force needs to increase even more, if we want to accomplish the task of the buildout itself, let alone running the facilities properly.

DFM 101: Solder Mask and Legend

One of the biggest challenges facing PCB designers is 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.

Designing PCBs With Additive Traces

Advances in technology have been clear to see within the component packaging industry, as the ball grid array (BGA) package sizes reduce from 1.0 mm pitch to 0.8 mm, 0.4 mm, and even beyond. However, while these improvements have occurred with component packages, it has become increasingly more difficult to break out and route the dense circuitry associated with these parts. Currently, the high-density interconnect (HDI) method typically used for the breakout of such parts has been to create the smallest possible subtractive-etched traces with microvias to allow for connections and escapes on the innerlayers of your PCB.

Designing Additive and Semi-Additive PCBs

With components getting smaller and electronic devices becoming more compact, we are reaching the physical limits of the typical etched fabrication processes. To address these limits, new additive and semi-additive processes are being developed to fit into the current fabricators’ production lines without too much disruption or extra cost.

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

Spring has definitely sprung, and the trade show season continues to roll right along. Managing Editor Nolan Johnson just returned from DesignCon 2022, and as he says in his review, the attendance was up from last year’s event, which had been at the McEnery Convention Center in the waning days of the pandemic. I hope we’re getting back to normal, whatever that means. This week, we have a few articles about Industry 4.0, as well as a column on setting your priorities. We have a cool article about methods for measuring the breakdown of resins during multiple thermal laminations, and a conversation with an EMS company president who realized that he was actually running a data collection firm that happened to make circuit boards. Can you say the same about your own company?

DesignCon 2022: Back to Business as Usual

It was something of a homecoming as DesignCon returned to the Santa Clara Convention Center this week for DesignCon 2022. It’s been two years since the last DesignCon was held in this venue just before the pandemic began. I attended DesignCon 2021 at the San Jose McEnery Convention Center in July of last year, and I could see a big improvement in attendance as DesignCon moved back into its usual venue.

AltiumLive 2022: Dwight Morse Offers a Supply Chain Primer

We’ll also cover a variety of rules of thumb that can help you stay away from trouble.

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

According to a quick look at history.com, “Some historians speculate that April Fools’ Day dates back to 1582, when France switched from the Julian calendar to the Gregorian calendar. In the Julian Calendar, as in the Hindu calendar, the new year began with the spring equinox around April 1.” All well and good, but why April Fools’? “People who were slow to get the news or failed to recognize that the start of the new year had moved to January 1 and continued to celebrate it during the last week of March through April 1 became the butt of jokes and hoaxes and were called “April fools.”

AltiumLive 2022: MacroFab Unites Design and Manufacturing in One Domain

I recently spoke with Joey Rodriguez, director of product management for MacroFab, which just announced a major partnership with Altium that brings supply chain information to Altium users much earlier in the design cycle. Joey and I discussed his AltiumLive presentation, now available online, which provides details about MacroFab’s efforts to “left-shift” supply chain information, and the need for designers to think holistically about the supply chain as early as possible in the design cycle.

Setting Goals for Your PCB Design Education

For our March issue of Design007 Magazine on planning your design education, we spoke with Bill Brooks of Nordson ASYMTEK, a long-time PCB designer, CID instructor, and fantastic sculptor. He is also one of the first to ever teach standalone PCB design courses in a college. After he earned his certification to teach the IPC CID workshops, Bill served as an adjunct instructor at Palomar College near San Diego, teaching beginning and advanced PCB design classes for 10 years. I asked Bill to share his thoughts on setting up a PCB design education career plan, and the need to stay on top of your game as a PCB designer.

AltiumLive 2022: Design for Availability

Andy Shaughnessy spoke with Rodrigo Contreras Lopez of SnapEDA about Rodrigo’s AltiumLive presentation, which is now available online. It’s a changing world, he says, and designers need to approach their designs from a different perspective: Creating designs with parts that may or may not be available now may just set up your design team and your customer for failure in a few years. Is Design For Availability going to enter the PCB design lexicon?

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

It’s been a crazy week, with lots of bad news coming out of Ukraine. (I’m a news junkie by trade, but I confess that some days I just unplug from the news completely to avoid overdosing on negativity.) And, as you might have guessed, this is all having ill effects on our electronics supply chain, which is already stretched thin. This is reflected in our IPC news item that shows an uptick in PCB sales in February, but a drop in bookings YOY, in part due to the trouble in Eastern Europe. But there’s positive news in this week’s top reads. We have a NextFlex article about an innovative flexible technology called flexible hybrid electronics (FHE) and a great interview by Dan Beaulieu. We also have a column by Travis Kelly, who discusses PCBAA’s efforts to lobby for American manufacturing in Washington. And last but not least, let’s welcome our two newest columnists, Paige Fiet and Hannah Nelson, who discuss their excitement about entering this industry.

Significant industry research led by NextFlex is optimizing the processes from design through manufacture for FHE products.

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

This week seems jam-packed with holidays, both major and minor, doesn’t it? We started with “International Pi Day” on March 14. With all the obligatory pricing specials on most all things “pie” here in the U.S., suffice it to say, I’ve got a short stack bake-at-home pizza “pi” in my freezer, thanks to the one-day-only sales price of $3.14. Personally, I’m glad they didn’t make the promotional price = pizza diameter * Pi.

AltiumLive 2022: Alex Sapp on How to Create a Better BOM

I recently spoke with Alex Sapp, director of API commercial strategy at Octopart, about his AltiumLive presentation, “How Resilient is Your BOM?” In this interview, Alex details the takeaways of his class, and some tips and techniques for creating more reliable BOMs and dealing with the current supply chain uncertainties.

Book Excerpt: 'The Printed Circuit Designer’s Guide to… High Performance Materials', Chapter 1

Choosing the right material for your application can be a major challenge. These are “cost to performance” decisions that need to be made to select material that will meet the expected performance requirements and the desired cost targets. Selecting a material that meets cost targets but fails to perform in prototype development testing results in costly revision spins, cost increases and delays to market. Chapter 1 of this book helps readers understand what resin choices to make for optimal electrical performance.

Planning Your Design Education: Keep an Open Mind

Rea Callender is the new vice president of education for Altium. He brings a background in business development and entrepreneurship, along with experience in K-12 education.
