It’s Only Common Sense: Why Should They Take Your Call?
The upcoming issue of Advanced Electronics Packaging Digest looks at what happens as advanced packaging pushes further into the limits of scale, power, thermal performance, and manufacturing capability. These features examine the measurement technologies, materials decisions, manufacturing investments, and system-level challenges shaping the next generation of advanced electronics.
Axel Lindloff of Koh Young examines the challenge of accurately measuring gaps as narrow as 20 µm between components hundreds of microns tall—dimensions already appearing in advanced packaging production. He explains why magnification alone cannot provide the accuracy manufacturers need and explores the role of multi-directional illumination, optical resolution, 3D reconstruction, and reliable reference data. As SiP, chiplet, and heterogeneous architectures become increasingly dense, precise dimensional measurement will be essential to maintaining process control and quality at production scale.
Chetan Arvind Patil of Marvell Technology explores the interconnected challenges emerging as AI accelerators and other high-performance systems move beyond the practical limits of monolithic processors. Advanced packaging provides a path forward, but greater package complexity introduces new constraints involving size, yield, testability, power delivery, thermal management, and manufacturing. Patil examines why overcoming one scaling limitation can create pressure elsewhere, and what it will take to turn increasingly complex, heterogeneous packages into reliable, economically scalable manufacturing platforms.
The issue also looks at the expansion of advanced electronics manufacturing in the United States. In an interview with I-Connect007, TTM Technologies President and CEO Edwin Roks discusses the company’s new UHDI facility in Syracuse and the broader evolution toward finer-feature PCBs, substrates, and heterogeneous packaging. Roks considers what will be required to build the domestic infrastructure needed to support these technologies and why strengthening the semiconductor ecosystem involves much more than semiconductor fabrication alone.
Finally, Chandra Gupta of Remtec Inc. examines a part of high frequency signal integrity that can be overlooked during design: the materials beneath the circuitry. Gupta explores the importance of dielectric stability, conductor surface roughness, and thermal behavior, as well as the limitations traditional PCB materials can present in demanding applications. He explains why ceramic substrates such as alumina and aluminum nitride can offer advantages for RF, high-power, and high-reliability systems, and why material selection should be considered early in the design process rather than after the geometry has been established.
Our features this month illustrate how the demands of advanced packaging are interconnected, from measuring microscopic features and managing extreme power densities to selecting the right materials and building the manufacturing infrastructure required to produce these systems at scale.
The next issue of Advanced Electronics Packaging Digest will be delivered to inboxes on Monday, Sept. 21. I-Connect007 Substack subscribers get early access on Sept. 18.
