Qnity Electronics, Inc., a premier technology solutions leader across the semiconductor value chain, introduced enhanced advanced packaging material solutions for organic interposer applications:

Trouble in Your Tank: The Role of Organic Solderability Preservatives in Advanced Packaging

06/08/2026 | Michael Carano -- Column: Trouble in Your Tank
Technology trends shaping the electronics industry supply chain—AI, IoT, ADAS, and high-performance computing (HPC)—are driving finer circuit features and higher layer counts. Advanced packaging drives the selection of surface finishes depending on the application. Typical designs require excellent solder joint reliability and wire bondability. It is not uncommon for designers to specify the organic solderability preservatives (OSP) on the BGA side of the substrate and precious-metal-plated finishes on the top side, which facilitate wire bonding.

The AI Tipping Point: Transforming Global Material Supply Chains

06/01/2026 | Marcy LaRont, I-Connect007 Magazine
While the AI revolution has the world focused on the promise of solving our most complex challenges, some laminate and PCB fabricators are raising concerns that the high-performance materials used to build AI data centers will gobble up the precious resources needed to produce them. PCB industry expert Mark Goodwin, COO of Ventec International, a laminate and equipment supplier, has expressed his concerns about the critical shortage of glass and copper, which he believes will worsen.

The Chemical Connection: The Consequences of Additive Metallizing on Etching Steps

06/01/2026 | Don Ball -- Column: The Chemical Connection
This month, I’m taking another look at additive manufacturing. What does mSAP, SAP, and additive metallizing (plating) look like in today’s advanced PCB fabrication? I must confess I don’t have a lot of insight, as my whole career has been devoted to removing copper from panel surfaces in even and controlled ways, and not to putting copper back on the panel. However, at some point in the additive process, especially in additive plating, copper must be removed from between the conducting surfaces to complete the circuits. Here, I can address some of the consequences of additive metallizing on subsequent etching steps.

Innovative Flash Copper Plating Technology

05/21/2026 | Andreas Schatz and Mustafa Özkök, MKS’ Atotech
The continuous push toward higher functionality, miniaturization, and performance in modern electronic devices—such as smartphones, wearables, and advanced computing platforms—has intensified the demand for high-density interconnect (HDI) printed circuit boards. Central to HDI performance is the reliable formation of blind microvias (BMVs), which serve as critical interlayer connections in modified semi-additive processes (mSAP).
