This course reviews how to perform a Random Vibration analysis of a Printed Circuit Board Assembly (PCBA) inside of Ansys Sherlock™ electronics reliability prediction software. This includes setting up a project in Ansys Sherlock software, performing a modal analysis, defining the loads and life cycle, defining the mount points, running the analysis, and reviewing the results. The primary failure modes of interest are solder fatigue & lead fatigue due to board bending, component motion, and lead bending under vibrational loads.
Learning Outcomes:
- Perform a natural frequency and random vibration analysis on a PCB, including setup and viewing results.
- Input both PSD and SRS vibrational loads.
- Review how to adjust PCB mount points and enable/disable lead modeling on components.
Prerequisites:
- Completion of the Ansys Sherlock Getting Started Course or prior knowledge of Ansys Sherlock software.
- Some working knowledge of random vibration loads such as PSD profiles is a plus.
Please note: These training materials were developed and tested in the 2024R2 release.
