Rigid-flex Design Guidelines 

Rigid-flex circuits are unique structures; part rigid board and part flex, they’re increasingly working their way into many of the electronic devices we use every day. There have been many advances in rigid-flex lately as more companies find themselves exploring this technology. So, before I started writing this article about rigid-flex design, I double-checked a few things. Fortunately, there is plenty of rigid-flex information available on a variety of great websites that we all know and trust.

Pivoting on Substrates

Oved Shapira is CEO of PCB Technologies, the Israeli-based printed circuit provider. PCB Technologies has recently invested in facilities and expertise to design, fabricate, and assemble substrates, a key component for advanced packaging technologies. Oved spoke with Barry Matties and Nolan Johnson about how advanced packaging will influence the industry. He said it will shift everything, including design, fabrication, assembly techniques, and capital equipment development. Some of these shifts might be subtle, and others more seismic. Whatever the changes, Oved says it’s coming.

Cutting-edge Inspection Challenges

Koh Young’s Brent Fischthal explains how UHDI and advanced packaging are challenging inspection systems. He says the shift toward larger components and advanced packaging brings a host of challenges that impact the industry. These challenges include complexity, density, package diversity, and inspection methodologies, all of which necessitate a more innovative approach.

The Honest Truth About Founders and Investors: An Author Interview

I was so impressed with "Founder vs. Investor: The Honest Truth about Venture Capital from Start up to IPO" by Elizabeth Zalman and Jerry Neumann that I just had to reach out to them. In my interview with the authors, they share how the book came about, how they often didn’t agree, and how vital that was to the integrity of the story they hoped to tell. I know this interview will be just as valuable for you as it was for me.

Towards a Silicon to Systems Industrial Strategy

"Electronics systems are at the heart of almost all modern technology. The performance and functionality of these systems have increased at breathtaking speed, chiefly as a result of advancements in semiconductor technology. Semiconductors do not function in isolation," writes Alison James, IPC senior director of government relations, in a 2023 report for the European Commission’s Directorate General for Internal Market, Industry, Entrepreneurship. "These electronics systems feature prominently in key sectors like defence, aerospace, space, automotive, medical, and high-performance computing, but electronics are vital to every industry and are central to a variety of EU priorities, including the twin digital and green transitions and Europe’s technological sovereignty."

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

This week has been chock full of news about upcoming trade shows and conferences. Clearly, the season is upon us. This week, I-Connect007 reported on PCB West in Santa Clara (often referred to as the show which kicks off trade show season) and the topic of artificial intelligence was everywhere. By the looks of it, not just at the conference, either. For months now, the mainstream media has been gobbling up all sorts of news about generative AI engines, painting the picture that we’ll all lose our jobs to these tools, while also reporting on situations where the results from AI have gotten progressively worse over time.

What is Ultra HDI?

Ever since high density interconnect (HDI) was created in 1982 by Hewlett-Packard to package its first 32-bit computer powered by a single chip, it has continued to evolve and provide the solutions for miniaturized products. The leading edge of HDI technology became the process used for organic flip-chip packaging for the semiconductor industry. The two distinct markets—IC substrates and product-system integration—are now colliding and utilizing the same ultra-HDI manufacturing processes.

The Drive Toward UHDI and Substrates

Panasonic’s Darren Hitchcock spoke with the I-Connect007 Editorial Team on the complexities of moving toward ultra HDI manufacturing. As we learn in this conversation, the number of shifting constraints relative to traditional PCB fabrication is quite large and can sometimes conflict with each other.

10 Steps to Outstanding

So often when I talk to PCB shop owners, they ask me how they can be outstanding. How can they position their own company to stand out from the crowd? That’s because one of the issues PCB shops face these days is they all seem to be alike. While they used to be judged and differentiated based on performance, now they all have very good quality.

Developing a Fabrication Business Strategy

Over the years, we’ve talked a lot about business strategies for PCB manufacturers here in the pages of PCB007 Magazine. But let’s back up a bit and look at the process for developing a new strategy. Where should you even begin? What’s your strategy for developing a strategy, if you will? We asked Chris Chapman, a Lean/Agile leadership coach and publisher of the Digestible Deming newsletter, to share his thoughts on developing successful business strategies and how the management philosophy of W. Edwards Deming can help leaders in our industry take their companies to the next level.

A Labor Day Holiday Notice

Today is a national holiday in both the United States and Canada (though the Canadians spell it Labour Day). The U.S. Labor Day has been federal holiday since 1894, and honors both the American labor movement and the contributions of laborers in the creation of the United States. Labor Day falls on the first Monday of September and is often considered the last day of summer in American culture. This is likely because the American school schedules resume around the beginning of September.
