White Paper: The Finite Element Analysis Methodology for Printed Circuit Board Assembly

Traditional approaches, such as Trace Mapping FEA, often encounter significant challenges due to uncertainties in material properties and high computational costs. This whitepaper introduces Wiwynn's innovative Hybrid FEA method, which integrates experimental data from three-point bending tests with numerical simulations to more accurately and efficiently determine material properties.

The Hybrid FEA method has proven effective in evaluating risks such as DIMM insertion stress, solder ball cracking, and power pin mounting deformation. Case studies demonstrate that the Hybrid FEA method delivers results comparable to traditional methods while significantly reducing computational demands.
