摘要: 对于系统级封装(SiP)器件,热应力引发的热失配是导致其失效的主要因素之一。基于有限元的仿真技术不仅能满足精度要求,还可显著节省时间与资源成本。然而,当前国内外针对SiP器件的热应力应变仿真方法缺乏系统的对比与验证。以某典型SiP模型为例,从收敛性分析、约束类型分析、温度场构建分析、焊接面分析、黏接面分析5个方面研究该封装器件的热应力应变仿真方法,最终结合实验进行对比分析,形成准确高效的SiP器件热应力应变仿真方法理论,从而为该领域的封装设计提供一定的科学指导。

Abstract: Thermal mismatch induced by thermal stress is identified as a primary failure factor in system-in-package (SiP) devices. Finite-element-based simulation techniques meet accuracy requirements while significantly reducing time and resource costs. However, systematic comparison and validation are lacking in current domestic and international thermal stress-strain simulation methods for SiP devices. Using a typical SiP model as an example, the thermal stress-strain simulation method for the packaging device is investigated from five aspects: convergence analysis, constraint type analysis, temperature field construction analysis, solder joint analysis, and adhesive interface analysis. Experimental comparison analysis is conducted to formulate an accurate and efficient theoretical framework for SiP device thermal stress-strain simulation, thereby providing scientific guidance for packaging design in this field.
