1525 Characteristics of Residual Thermal Stresses at a Vertex in Three-Dimensional Joints with Three-Layers
Details
A mismatch of different material properties in joints may cause stress singularities, which lead to the failure of the bonding part. Furthermore, thermal residual stresses occur in a cooling process after bonding the joints, and the stress singularity for thermal stress also occurs. In the present study, a boundary element method is used for evaluating the intensity of stress singularity. Analysis model is 3-layer model, and consist of silicon, resin and FR4.
