Current IssueSignal Integrity
If you don’t have signal integrity problems now, you will eventually. This month, our expert contributors share a variety of SI techniques that can help designers avoid ground bounce, crosstalk, parasitic issues, and much more.
Proper Floor Planning
Floor planning decisions can make or break performance, manufacturability, and timelines. This month’s contributors weigh in with their best practices for proper floor planning and specific strategies to get it right.
Showing Some Constraint
A strong design constraint strategy carefully balances a wide range of electrical and manufacturing trade-offs. This month, we explore the key requirements, common challenges, and best practices behind building an effective constraint strategy.

I-Connect007 Editor’s Choice: Five Must-Reads for the Week
December 25, 2020 | Nolan Johnson, I-Connect007Estimated reading time: 2 minutes

We started this week with the solstice. Here in the Northern Hemisphere, it’s the winter solstice; south of the equator, of course, it’s the summer solstice. Not only is this a big event on the astronomical calendar, solstice is a busy time for holy days worldwide. Whichever holiday schedule you follow, we wish that yours is festive, restorative, and full of hopefulness.
All that holiday revelry can certainly distract one’s attention; as evidenced in a much slower news week. As a result, this week’s Top 5 brings you the three most important and/or intriguing pieces of news we’ve covered in the last week, and two items from last week that are still drawing reader attention this week. That’s I-Connect007: Keeping you informed, efficiently.
Enjoy your holiday and Happy New Year!
Prices of Copper-Clad Laminates Continue to Rise
December 18
Recently, two major explosions at epoxy resin plants in China had a great impact on domestic resin suppliers, interrupting the supply of resin and caused prices to increase dramatically. I-Connect007 reports on the market dynamics and effects.
The press release states, “Industry experts believe a five-year, $40 million investment in a public-private R&D program would yield more than $100 million in U.S. defense savings per year and improve military readiness and overall innovation. The Congress provided $5 million for such R&D in FY 2020.”
For more detail, find IPC President and CEO John Mitchell’s article in Defense News titled, “Protecting America’s military prowess requires an embrace of lead-free electronics.”
COMSovereign Delivers First Tethered Drone-Based LTE Network
December 21
Emergency and disaster response teams are a great example for this new LTE mobile network system. Imagine a wildfire command post setting up on a remote hilltop and launching a series of hovering drones to serve as temporary cell towers in an area otherwise outside cell service.
Dr. John Mitchell on IPC APEX EXPO Going Virtual
December 16
In this audio interview, Barry Matties and Dr. John Mitchell discuss IPC’s decision to move IPC APEX EXPO 2021 to an all virtual platform. Mitchell explains the reasoning for going virtual, and expresses his enthusiasm for the opportunities this presents the conference. I-Connect007 will be providing preshow and realtime coverage of IPC APEX EXPO, so check with us often to get the latest.
Happy Holden: ECWC15 Virtual Event a Success

Trouble in Your Tank: Implementing Direct Metallization in Advanced Substrate Packaging
09/15/2025 | Michael Carano -- Column: Trouble in Your TankDirect metallization systems based on conductive graphite are gaining popularity throughout the world. The environmental and productivity gains achievable with this process are outstanding. Direct metallization reduces the costs of compliance, waste treatment, and legal issues related to chemical exposure. A graphite-based direct plate system has been devised to address these needs.
Closing the Loop on PCB Etching Waste
09/09/2025 | Shawn Stone, IECAs the PCB industry continues its push toward greener, more cost-efficient operations, Sigma Engineering’s Mecer System offers a comprehensive solution to two of the industry’s most persistent pain points: etchant consumption and rinse water waste. Designed as a modular, fully automated platform, the Mecer System regenerates spent copper etchants—both alkaline and acidic—and simultaneously recycles rinse water, transforming a traditionally linear chemical process into a closed-loop system.
Driving Innovation: Depth Routing Processes—Achieving Unparalleled Precision in Complex PCBs
09/08/2025 | Kurt Palmer -- Column: Driving InnovationIn PCB manufacturing, the demand for increasingly complex and miniaturized designs continually pushes the boundaries of traditional fabrication methods, including depth routing. Success in these applications demands not only on robust machinery but also sophisticated control functions. PCB manufacturers rely on advanced machine features and process methodologies to meet their precise depth routing goals. Here, I’ll explore some crucial functions that empower manufacturers to master complex depth routing challenges.
Trouble in Your Tank: Minimizing Small-via Defects for High-reliability PCBs
08/27/2025 | Michael Carano -- Column: Trouble in Your TankTo quote the comedian Stephen Wright, “If at first you don’t succeed, then skydiving is not for you.” That can be the battle cry when you find that only small-diameter vias are exhibiting voids. Why are small holes more prone to voids than larger vias when processed through electroless copper? There are several reasons.
The Government Circuit: Navigating New Trade Headwinds and New Partnerships
08/25/2025 | Chris Mitchell -- Column: The Government CircuitAs global trade winds continue to howl, the electronics manufacturing industry finds itself at a critical juncture. After months of warnings, the U.S. Government has implemented a broad array of tariff increases, with fresh duties hitting copper-based products, semiconductors, and imports from many nations. On the positive side, tentative trade agreements with Europe, China, Japan, and other nations are providing at least some clarity and counterbalance.
