Current IssueThe Hole Truth: Via Integrity in an HDI World
From the drilled hole to registration across multiple sequential lamination cycles, to the quality of your copper plating, via reliability in an HDI world is becoming an ever-greater challenge. This month we look at “The Hole Truth,” from creating the “perfect” via to how you can assure via quality and reliability, the first time, every time.
In Pursuit of Perfection: Defect Reduction
For bare PCB board fabrication, defect reduction is a critical aspect of a company's bottom line profitability. In this issue, we examine how imaging, etching, and plating processes can provide information and insight into reducing defects and increasing yields.
Voices of the Industry
We take the pulse of the PCB industry by sharing insights from leading fabricators and suppliers in this month's issue. We've gathered their thoughts on the new U.S. administration, spending, the war in Ukraine, and their most pressing needs. It’s an eye-opening and enlightening look behind the curtain.

atg Luther & Maelzer and IEC Install A7Pro Flying Probe Tester at Toronto-based PCB Factory
February 19, 2024 | IECEstimated reading time: Less than a minute

Longest-serving distributor to the North American PCB industry, IEC (International Electronic Components) confirms that the atg Luther & Maelzer A7Pro, eight-head, double-sided, high-speed flying probe test system has been ordered and installed at a prominent PCB manufacturer in Toronto, Canada.
IEC President Shawn Stone says, “IEC attributes our longevity to the expertise and dedication of our sales team leaders, our loyal customers, and strategic partners such as atg Luther & Maelzer.”
atg’s A7Pro testers utilize eight flying probe test heads, multiple optical recognition systems, and a wide variety of advanced, high-speed electrical test measurement techniques to electrically test all types of PCBs for continuity and isolation. Board sizes of 24" x 21" (or larger), with small pad/fine pitch technology can be tested quickly and easily. Special options such as 4-wire Kelvin tests, hi-pot test, latent defect test, and others can be provided.

Study on Resonance Mitigation in Metallic Shielding for Integrated Circuits
07/08/2025 | Article by Maria Cuesta Martin, Victor Martinez, Vidal Gonzalez Aguado, Würth ElektronikInherent cavity resonant modes often lead to significant degradation of shielding effectiveness, responsible for unwanted electromagnetic coupling. Cavity resonant modes of the metal shielding enclosure can produce two adverse problems: the mutual coupling among different RF modules and shielding effectiveness reduction of the metal enclosure. The cabinets serve to shield certain components from electromagnetic interference (EMI). However, these cavities present some resonance peaks at 5 GHz, making it impossible to use them at higher frequencies.
The Global Electronics Association Releases IPC-8911: First-Ever Conductive Yarn Standard for E-Textile Application
07/02/2025 | Global Electronics AssociationThe Global Electronics Association announces the release of IPC-8911, Requirements for Conductive Yarns for E-Textiles Applications. This first-of-its-kind global standard establishes a clear framework for classifying, designating, and qualifying conductive yarns—helping to address longstanding challenges in supply chain communication, product testing, and material selection within the growing e-textiles industry.

Defense Speak Interpreted: Is DARPA Still Around After CHIPS?
06/24/2025 | Dennis Fritz -- Column: Defense Speak InterpretedWhen I first published my Defense Speaks Interpreted column in January 2019 on the Defense Advanced Research Projects Agency (DARPA ERI), the agency advocated for an expanded Defense emphasis on closing the growing technology gap in microelectronics. The emphasis was on “resurgence.”
I-Connect007 Editor’s Choice: Five Must-Reads for the Week
06/13/2025 | Marcy LaRont, I-Connect007Today is Friday the 13th, and in much of Western folklore, this is a day when bad luck is lurking. But while Friday the 13th may top Western superstition charts, the global calendar is sprinkled with its own unlucky legends. In Spain and Greece, the bad juju lands on Tuesday the 13th—a day linked to Mars, the god of war, and naturally, chaos. In Italy, it’s Friday the 17th that is feared, thanks to the Roman numeral XVII, which can be rearranged to spell VIXI—Latin for “I have lived” (a poetic way of saying you’re dead).
