Happy’s Tech Talk #35: Yields March to Design Rules

12/12/2024 | Happy Holden -- Column: Happy’s Tech Talk
Ultra high density interconnect (UHDI) has many forms, structures, and alternatives, so capturing all the variations and reducing them to design rules has required some departures from traditional IPC design standards. In this column, I’ll be discussing the IPC UHDI design guidelines and standards. The fundamental question is: “Do you need HDI or microvias?”

The Shaughnessy Report: A Stack of Advanced Packaging Info

12/10/2024 | Andy Shaughnessy -- Column: The Shaughnessy Report
It’s only fitting that this issue on advanced packaging and stackup features a “stackup” of “packages” on the cover. There’s certainly a lot to “unpack” in this issue. As advanced packaging moves further into the mainstream of PCB design, more PCB designers and design engineers are realizing this isn’t a plug-and-play technology. As we see in this issue, advanced packaging can have an impact on the entire design—the stackup in particular.

UHDI Fundamentals: ‘UHDI’ Bleeding-edge Entertainment Applications, Part 1

10/10/2024 | Anaya Vardya, American Standard Circuits
As soon as we cross below the 1-mil (0.001") line width threshold, we need to stop talking in terms of mils and ounces and begin talking in terms of microns. For reference, a 3-mil trace is 75 microns, so a 1-mil trace is 25 microns. In general terms, ultra high density interconnect refers to line and spaces on a printed circuit board that are sub-25 micron. In the context of this article, ultra high-definition interconnect (UHDI) refers to the technology and infrastructure used to transmit and connect ultra high-definition signals, typically 4K, 8K, or even higher resolutions, across devices like displays, cameras, servers, and processors.
