Ansys Sherlock - Electronics Reliability Prediction Software

Trace Modeling Reinforcement with Ansys Sherlock

When a thermal or thermal-stress analysis is needed for design of electronics PCB or packaging, it is important to consider the impact of copper traces. Historically, traces have been modeled using Effective Material Properties or Mapped Material Properties (Trace Mapping). The most recent and most accurate technique is Trace Reinforcement Modeling used in both Ansys Sherlock (electronics reliability prediction software) and Ansys Mechanical (finite element analysis) software tools.

The Trace Reinforcement Modeling procedure begins by loading ECAD (e.g. ODB++) into Sherlock, then exporting to an Ansys Workbench project (transfering components, materials, etc). Traces are exported from Sherlock using the .STEP file format and imported to the same Workbench project, where assignments are added for thickness and materials.

Using this simple and straightforward technique we can perform detailed and accurate Structural/Thermal/Dynamic/ Thermal-Stress analysis of the electronics assembly. We can calculate temperature, deformation, and stress distributions for the PCB, components and traces.

Parametric Turbomachinery Design and Simulations: An Introduction to CFturbo

March 18, 9:00 AM PT

Abstract

Turbomachinery design and fluid-flow simulations have reached new levels in turnaround time, robustness, and prediction accuracy in recent years. It became possible by combining high-fidelity CFD-solvers with optimization codes and parametric, knowledge-based conceptual design software. In this talk, we will present CFturbo’s fast and user-friendly approach to designing Turbomachinery components from the ground up, simulating performance curves, and getting optimized geometries using Ansys CFX and Ansys optiSlang. The showcase will be a cryogenic rocket turbopump.
