PCB operating temperatures and loss
Controlling stackup design with Z-planner Enterprise
The overwhelming majority of PCB signal-integrity simulations are performed at lab-temperature conditions, while systems in actual operation typically run at significantly higher temperatures. As a result, SI simulations almost always underestimate the actual losses signals will see in real-world operation, which compromises design margins and in some cases can lead to prototype or field failures.
This webinar examines how laminate material properties typically behave as operating temperature increases, and how those changes affect insertion loss. We will discuss the role of laminate resin systems and loss categories and highlight why changes in Df should be accounted for during stackup planning and signal-integrity analysis.
You will learn:
- About key laminate properties that impact PCB performance at elevated temperatures
- How Df and bulk conductivity vary with temperature and how this behavior influences loss budgets
- Df variation as a function of loss category and temperature
- How Dk varies with temperature
- Relative comparisons between dielectric loss, resistive loss, and losses tied to copper roughness
- How to make operating-temperature-aware adjustments in Z-planner Enterprise to build more realistic, conservative loss simulations as part of your design flow
Who should attend:
- Hardware engineers
- PCB designers
- Signal-integrity engineers
