Current IssueInner Layer Precision & Yields
In this issue, we examine the critical nature of building precisions into your inner layers and assessing their pass/fail status as early as possible. Whether it’s using automation to cut down on handling issues, identifying defects earlier, or replacing an old line...
Engineering Economics
The real cost to manufacture a PCB encompasses everything that goes into making the product: the materials and other value-added supplies, machine and personnel costs, and most importantly, your quality. A hard look at real costs seems wholly appropriate.
Alternate Metallization Processes
Traditional electroless copper and electroless copper immersion gold have been primary PCB plating methods for decades. But alternative plating metals and processes have been introduced over the past few years as miniaturization and advanced packaging continue to develop.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week
June 30, 2023 | Nolan Johnson, I-Connect007Estimated reading time: 2 minutes
It’s a heady time here in the U.S. between the summer holidays of Memorial Day (last Monday in May) and Independence Day (July 4). This four-week period straddles the Northern solstice, boasts the longest days of the year in the Northern Hemisphere. This is the high season for outside activities, which may be pulling you away from the office. Am I right? Never fear, I-Connect007 is here to deliver the “must know” news stories.
I’m bending the rules (again) this week by adding some additional links to some of the news items, so as to provide a more comprehensive picture of the story. So, what do we have? A conversation with Omron, news from Isola and Insulectro, Pete Starkey’s EIPC Summer Conference coverage (keynote, Day 1 and Day 2 summaries), and IPC monthly sales reports for EMS and PCB fab.
If you’re in the U.S., have a wildly independent holiday weekend; for our global readers, we’ll still be here, watching the news for you. Stay tuned.
Omron Discusses SPI, AI and More
Published June 26
At the recent SMTA Oregon Tech Forum and Expo, Tim Anderson, a senior account manager at Omron, presented his insights on SPI, the latest trends in the industry, and some solutions to consider. Afterward, Barry Matties caught up with Anderson for a follow up discussion. As Anderson points out, the SPI, AOI, and AXI systems of today do far more than simply catch defects. This is a short and informative read for anyone following these machinery applications.
Isola Changing With the Times
Published June 29
Changing market conditions require changes in approach. I-Connect007’s Barry Matties and Nolan Johnson spoke with Isola’s Travis Kelly, Sean Mirshafiei, and Kirk Thompson about Isola’s recent responses to market conditions. In this interview, Kelly, Mirshafiei, and Thompson outline recent changes to Isola senior leadership, optimizing manufacturing to meet the needs of the global market, and the strategic importance of advanced packaging to the global economy, and to the U.S., in particular.
EIPC Summer Conference 2023: The Keynote Session
Published June 26
The EIPC technical sessions–whether the monthly snapshot sessions, or the semi-annual conferences– are eternally full of high-value technical updates. This year’s summer session follows that same tradition. Of course, Pete Starkey’s detailed narratives always bring an extra bit of humanity to the sessions. We’re leading with Mr. Starkey’s coverage of the keynote, but I’ve added links to the summaries for Day 1 and Day 2 here, as well.
Insulectro Announces New Partnership With Laminate Suppliers Arlon Electronics Materials and EMC
Published June 27
Insulectro announces its new status as exclusive distributor for North America of Arlon copper clad laminates beginning Sept. 4, 2023. In addition, Arlon is the master distributor for Elite Materials Company (EMC), based in Taiwan. This brings both product lines to the Insulectro line card. Read here to get the details.
North American EMS Industry Up 7.1% in May
Published June 22
Read the whole post here, but just to tease the content, “EMS bookings in May increased 0.8 percent year-over-year and increased 4.4 percent from the previous month.” Also linked to the EMS report is the PCB fabrication report: North American PCB Industry Sales Up 6.7% in May

Designers Notebook: Impact of Advanced Semiconductor Packaging on PCB Stackup
01/07/2025 | Vern Solberg -- Column: Designer's NotebookTo accommodate new generations of high I/O semiconductor packaging, printed circuit board fabrication technology has had to undergo significant changes in both the process methods and the criteria for base material selection and construction sequence (stackup). Many of the new high-function multi-core semiconductor package families require more terminals than their predecessors, requiring a significantly narrower terminal pitch. Interconnecting these very fine-pitch, high I/O semiconductors to the PCB is made possible by an intermediate element referred to as an interposer.
BOOK EXCERPT: The Printed Circuit Designer’s Guide to... High Performance Materials, Chapter 4
01/02/2025 | I-Connect007In Chapter 4, Michael Gay discusses the two main types of copper foil used for PCB boards today: electrodeposited (ED) foil and rolled annealed (RA) foil. He also explains the pros and cons of each, and provides an update of the latest innovations in copper foil technology.
Connect the Dots: Designing for Reality—Solder Mask and Legend
01/02/2025 | Matt Stevenson -- Column: Connect the DotsIn the previous episode of I-Connect007’s On the Line with… podcast, we discussed the strip, etch, and strip process. At this point, we have a functioning board, but we still need to protect the PCB from environmental effects and document the circuit components. This brings us to the solder mask and legend phase of production.
Global PCB Connections: Following DFM Rules Leads to Better Boards
12/18/2024 | Jerome Larez -- Column: Global PCB ConnectionsAs a PCB field applications engineer, ensuring smooth communication between PCB designers and fabricators is one of my frequent challenges. A critical part of that dialogue is design for manufacturing (DFM). Many designers, even experienced ones, often misunderstand or overlook important DFM considerations. They may confuse design rules with manufacturing minimums, leading to technically feasible designs that are difficult or costly to produce. In this column, I will clarify some common DFM guidelines and help designers understand the difference between “design rules” and “minimums” while sharing best practices that will simplify the production process and ensure the highest quality PCB.
Sayonara to the Last Standing Copper Foil Plant in North America
12/17/2024 | Marcy LaRont, I-Connect007In July 2021, PCB007 Magazine published an interview with Michael Coll and Chris Stevens of Nippon Denkai about the new acquisition by Nippon Denkai of the last-standing ED foil manufacturer in North America. The plant in Augusta, Georgia, was formerly owned by Oak Mitsui, Inc. and had been purchased by Nippon Denkai the previous March, after which significant investment was made with the expectation of providing more jobs.
