ECAD/PCB Workflows for Electromagnetic Coupling and Lorentz Force Analysis
1-2 HOURS
Magnetically induced noise and vibration due to Lorentz force in multilayer PCBs has a significant impact on the design of consumer electronics products such as smartphones, wearables, headphones, and laptops. The noise issues can be more pronounced when permanent magnets are placed near the PCBs, which is not uncommon as the consumer electronics device size shrinks in recent years. To avoid delays in product release and product recalls once a device is released to the market, it is required to predict the noise and vibration accurately and efficiently by calculating Lorentz force density in multilayer PCBs during the design stage. In this course, the following topics are covered:
- Importing board files into 3D layout, then exporting as a layout component into Ansys Maxwell® advanced electromagnetic field solver
- Automation of excitations and meshing setup in Maxwell A-phi transient solver
- Computation of magnetic fields and harmonic forces in Maxwell
- PCB analysis with MCAD components
ECAD integration in Ansys Maxwell software enables you to handle complex PCB layouts, while the state-of-art phi+ mesher increases the meshing speed. The harmonic forces computed by Ansys Maxwell software can be imported into Ansys Mechanical software for acoustic analysis on the PCB board.
Learning Outcomes:
Following completion of this course, you will be able to:
- Prepare board file in 3D Layout and import ECAD as a layout component in Ansys Maxwell software A-Phi transient solver.
- Pre-processing of ECAD, including region creation, boundary and excitation assignment, and solution setup.
- Harmonic force and RLC matrix calculation
- Post-processing of force, loss, RLC results and field visualization.
- Analysis of ECAD combining with MCAD components.
Please note: These training materials were developed and tested in the 2026R1 release.
