    Abstract: When reliability evaluation of the whole electronic package is performed, the time required for simulation is decreased, while solder connection parts, in particular, are accurately analyzed. The whole analysis model creating unit creates a solder connection part model which has the same volume, height, and connection area as the volume, height, and connection area of the solder connection part. By means of dividing the solder connection model into multiple meshes, the first mesh data for use in electronic package analysis is created.

    Abstract translation: 当执行整个电子封装的可靠性评估时,模拟所需的时间减少,特别是焊接连接部分被精确地分析。 整个分析模型创建单元产生与焊料连接部分的体积,高度和连接面积相同的体积,高度和连接面积的焊料连接部分模型。 通过将焊接连接模型划分为多个网格,创建用于电子包装分析的第一个网格数据。

    Abstract: The distortion of each node is calculated from the distortions of respective elements in the finite element analysis result of a global model of a structure, and a second-order coefficient of a quadratic function representing the displacement at each node of a micro model is calculated from distortions of respective nodes. In addition, a constant term and a first-order coefficient of the quadratic function are calculated from the displacements of the respective nodes of the global model. Then, the displacement at each boundary node of the micro model is calculated using the obtained quadratic function and a finite element analysis of the micro model is performed.

    Abstract: An element damage determination unit calculates a cumulative value of a damage value using a Manson-Coffin law for a plurality of finite elements of a continuum based on a result of a stress/distortion analyzing process, and determines whether or not the cumulative value of the damage value is equal to or exceeds a threshold. A calculation unit obtains first correspondence information indicating the correspondence between the number of cycles of a load and a growth rate of a crack occurring in the continuum based on the determination result. A Manson-Coffin law change unit changes a Manson-Coffin law based on the first correspondence information and second correspondence information indicating the correspondence between an actual measurement value of the number of cycles of a load applied to the continuum and an actual measurement value of the growth rate of a crack occurring in the continuum at that time.
