dc.description.abstractElectronic packages are exposed to complex life-cycle environments, and in many cases that environment involves exposure to multiaxial vibration which can dangerously affect the integrity of the electronic package’s functionality due to nonlinear amplification of the multiaxial response, in comparison to the corresponding uniaxial responses. This has particular implications in vibration durability testing of electronic assemblies, since conventional tests in industry are often run sequentially as set of uniaxial tests along orthogonal axes. This is in part because multiaxial vibration tests can be expensive and complex when the response becomes significantly nonlinear. The severity of the nonlinear response is known to depend both on the multiaxial excitation parameters and on the component architecture. Prior studies have investigated the nonlinear effects of varying the loading parameters through modeling and testing, while this study focuses on quantifying the effects of component geometry. The approach is based on a combination of multiaxial vibration testing and modeling to conduct a parametric study with components of different geometries. The findings of this study will provide important guidance when developing guidelines about when multiaxial response is important, instead of sequential uniaxial testing along orthogonal axes.en_US
