摘要:针对叠层结构的热应力和散热问题,利用 ABAQUS 软件,建立了叠层结构热应力和流
体动力学分析模型。从热应力分析可知,在芯片和板两种材料结合部位的应力较大。流体动
力学分析表明,在叠层间空气的流动较外表面小。最后,对叠层结构的有限元分析结果进行
了讨论。

Abstract: Laminated structure for heat stress and heat issues, the use of ABAQUS software, the laminated
structure thermal stress and fluid dynamics model are estabilshed. From the thermal stress analysis shows
that the two materials in the chip and board-binding site of stress is large. Fluid dynamics analysis shows
that the flow of air between the laminate over the outer surface of the small. Finally, the laminated structure
of the finite element analysis results are discussed.
Key words: laminated structure; thermal finite element analysis; flunent dynamics analysis, ABAQUS
