A Workflow for Fatigue Analysis of Solder Joints in PCB Under Vibrational Loading
The trend towards the electrification of vehicle drives requires the development of electronic components that can withstand multiple types of loads, e.g., static, dynamic, and thermal-mechanical loads. One great challenge here is the reliability assessment of printed circuit board assemblies (PCBAs) by finite-element analyses (FEAs), because the PCBA geometry is usually really complex and the resulting computational effort in the FEAs is therefore huge. The geometrical complexity is caused by the details of a PCB layout, which is defined by multiple layers of copper traces and hundreds or even thousands of vias, and the vast number of surface mounted devices and solder joints. The computational effort is a result of the geometrical complexity, i.e., leading to detailed finite element models of solder joints, copper traces and vias.
In this talk we present our state-of-the-art simulation processes for the structural reliability analysis of PCBAs and we show how these processes benefit from FEA process automation. The highlights of the FEA process automations are the automatic generation of detailed solder joint FE-models, the automatic generation of detailed FE-models of PCBs based on ECAD-data, and sub-modeling, sub-structuring, and material-homogenization techniques for the reduction of the computational effort in the FEAs.
Accelerate Your Model-Based Workflows Throughout the Manufacturing Process
A seamless model-based workflow throughout the manufacturing process is essential for the companies in electronic industry to achieve short lead times and remain competitive under a short product life cycle. However, non-innovative work is required due to the typical bottlenecks like poor product data quality and/or manual work often blocks/breaks the process and workflow. Learn how our technology accelerates your model-based process with example use cases.

Determining Unknown Simulation Parameters using RAMDO Calibration for Simulation Model Validation
This will present two different industry case studies showing how RAMDO Calibration was used to identify unknown simulation parameters to improve simulation results. One case study will show how experimental test data of a mechanical spring was used with RAMDO Calibration in order to determine a simulation parameter value that improves the prediction of the spring stiffness. Using the calibrated parameter value resulted in prediction errors being less than 1%. The second case study will show how experimental test data was used to determine the internal plate thickness of a cell in a vehicle battery when the battery is fully charged. The initial plate thickness before charging was known and RAMDO Calibration was used to determine the plate thickness when the battery is full charged.
