Current IssueAdvanced Packaging and Stackup Design
This month, our expert contributors discuss the impact of advanced packaging on stackup design—from SI and DFM challenges through the variety of material tradeoffs that designers must contend with in HDI and UHDI.
Rules of Thumb
This month, we delve into rules of thumb—which ones work, which ones should be avoided. Rules of thumb are everywhere, but there may be hundreds of rules of thumb for PCB design. How do we separate the wheat from the chaff, so to speak?
Partial HDI
Our expert contributors provide a complete, detailed view of partial HDI this month. Most experienced PCB designers can start using this approach right away, but you need to know these tips, tricks and techniques first.

White Paper: Optimization Methods for High-Speed SerDes Channels
March 24, 2022 | Siemens Digital IndustriesEstimated reading time: Less than a minute
Cost-effective implementation of these high-bandwidth channels across high-volume manufactured products requires analysis of many design and manufacturing parameters.
This Siemens white paper presents a new approach for the systematic analysis of SerDes channel compliance at 25Gbps and above. Using a 100GBASE-KR4 electrical backplane design, the methodology reveals the system's sensitivity to various design variables, intelligently explores the design space, and provides a high-level description of the automation involved in the analysis process. Demand for higher bandwidth has greatly increased the signaling data rates for SerDes.

IPC, FED Partner for New Design Conference in Vienna
12/12/2024 | Andy Shaughnessy, Design007 MagazineIPC and its German partner FED have teamed up to create a new PCB design conference in Vienna, Austria. The Pan-European Electronics Design Conference (PEDC) is scheduled for Jan. 29-30 at the NH Danube City hotel in Vienna. IPC’s Peter Tranitz, one of the show organizers, discussed how this new show came about, pointing out that, unlike many of the regional conferences in Europe, PEDC will host curated, peer-reviewed presentations, not promotional content or product pitches. Will PEDC become an annual event?
Happy’s Tech Talk #35: Yields March to Design Rules
12/12/2024 | Happy Holden -- Column: Happy’s Tech TalkUltra 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 ReportIt’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.

Advanced Packaging and Stackup Design: December 2024—Design007 Magazine
12/09/2024 | I-Connect007 Editorial TeamIn this month's issue,, we asked our expert contributors to discuss the impact of advanced packaging on stackup design—from SI and DFM challenges through the variety of material tradeoffs that designers must contend with in the arena of HDI and UHDI. And with a little research, planning, and collaboration with the fabricator, any seasoned PCB designer can utilize advanced packaging.
