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.

Effects of Advanced Packaging and Stackup Design
12/26/2024 | I-Connect007 Editorial TeamKris Moyer teaches several PCB design classes for IPC and Sacramento State, including advanced PCB design. His advanced design classes take on some really interesting topics, including the impact of a designer’s choice of advanced packaging upon the design of the layer stackup. Kris shares his thoughts on the relationship between packaging and stackup, what PCB designers need to know, and why he believes, “The rules we used to live by are no longer valid.”
Beyond Design: AI-driven Inverse Stackup Optimization
12/26/2024 | Barry Olney -- Column: Beyond DesignArtificial intelligence (AI) is transforming how we conceptualize and design everything from satellites to PCBs. Traditionally, stackup planning is a manual process that can be multifaceted and relies heavily on the designer's expertise. Despite having best practices and various field solvers to optimize parameters, stackup planning remains challenging for complex designs with advanced packaging, several layers, multiple power pours, and controlled impedance requirements.
