Beyond Design: The Fundamental Structure of Spectral Integrity
10/21/2025 | Barry Olney -- Column: Beyond DesignImpedance can be characterized in both the time and frequency domains. In the time domain, it influences how electromagnetic energy propagates through interconnects, affecting signal integrity and waveform fidelity. In the frequency domain, AC impedance determines how well the network can suppress noise and deliver clean power at a range of frequencies. AC impedance shapes how power rails respond to transient loads.
The Shaughnessy Report: Watt About Power Integrity?
10/08/2025 | Andy Shaughnessy -- Column: The Shaughnessy ReportYes, that headline is the equivalent of a dad joke, but editors can’t pass up a chance to inject a little humor into a headline, and I had to take my shot. Power integrity (PI) problems are no joke. Current power demands are increasing, especially with AI, 5G, and EV chips, which can lead to voltage drops that kill your performance.
Beyond Design: Slaying Signal Integrity Villains
09/17/2025 | Barry Olney -- Column: Beyond DesignHigh-speed PCB design is a balancing act, where subtle oversights can develop into major signal integrity nightmares. Some culprits lie dormant during early validation, only to reveal themselves later through workflow disruptions and elusive performance bottlenecks. Take crosstalk, for example. What begins as a stray signal coupling between traces can ripple through the design, ultimately destabilizing the power distribution network. Each of these troublemakers operates with signature tactics, but they also have well-known vulnerabilities.
Polar Instruments Announces Additive Transmission Line Support for Si9000e
08/20/2025 | Polar InstrumentsTransmission lines embedded into the PCB surface are a feature of UHDI constructions. The 2025 fall release of Polar's Si9000e PCB impedance & insertion loss transmission line field solver incorporates eight new single ended, differential and coplanar transmission line structures.
I-Connect007 Editor’s Choice: Five Must-Reads for the Week
05/30/2025 | Andy Shaughnessy, Design007I don’t have a scorecard, but I do have a weekly wrap-up of must-reads that I think deserve another “bite of the apple,” so to speak. IPC’s Rich Cappetto shares his perspective on everything from tariffs to the CHIPS Act. Columnist Josh Casper discusses the use of AI in 3D AOI systems and the immediate benefits that AI can bring about. Columnist Anaya Vardya explains how technologies like AI can improve our customer service, as well as our manufacturing processes.
