摘要: 电子封装是芯片成为器件的重要步骤,涉及的材料种类繁多,大量材料呈现显著的温度相关、率相关的非线性力学行为。相关工艺过程中外界载荷与器件的相互作用呈现典型的多尺度、多物理场特点,对电子封装的建模仿真方法也提出了相应的要求。在可靠性验证方面,封装的失效主要包括热-力致耦合失效、电-热-力致耦合失效等。随着新型封装材料、技术的涌现,电子封装可靠性的试验方法、基于建模仿真的协同设计方法均亟待新的突破与发展。

Abstract: Electronic packaging is the key step that make chips become functional devices. Many different types of materials are involved in this step, majority of which show non-linear mechanical behaviors with significant temperature dependency and strain rate dependency. During the processes, the interactions between loads from the environment and devices are multi-scale and multi-physics in nature. This also poses new requirements on modeling and simulation techniques in electronic packaging. As for reliability validation, typical failure modes in electronic packaging include thermal-mechanical coupling failure and electrical-thermal-mechanical coupling failure and so on. With the development of new packaging materials and technologies, new approaches are in demand in experimental methodology and modeling and co-design techniques.

Key words: electronic packaging, reliability, packaging materials, modeling, failure mechanisms, LED, power devices, integrated circuit
