摘要
针对叠层结构的热应力和散热问题,用Abaqus建立叠层结构热应力和流体动力学分析模型.热应力分析结果表明在芯片与板两种材料结合部位的应力较大;流体动力学分析结果表明在叠层间空气的流动比外表面小.
As to the heat stress and heat issues of laminated structure, the thermal stress and fluid dynamics models of laminated structure are built using Abaqus software. The thermal stress analysis results show that the stress at the two material combination between the chip and the board binding site is large. The fluid dynamics analysis results show that the flow of air between the laminates is smaller than that of the outer surface.
