Analysis of sress-strain in soldered joints and optimization of temperature profile of HALT thermal cycling test

    摘要
  • 摘要: 以统一型粘塑性Anand本构方程为基础,采用非线性有限元方法研究了热循环试验过程中高低温端点温度、温度升降速率、高低温保持时间对Sn63Pb37焊点应力分布和塑性应变的影响,并结合基于塑性应变的疲劳寿命预测Coffin-Masson公式,分析了热循环试验效率与这些参数之间的关系,为建立优化的HALT(Highly accelerated life test)和其它可靠性热循环试验温度剖面图提供有价值的参考。

     

    Abstract: Based on the unified visco plastic An and constitutive equation,the nonlinear finite element method is applied to study the influence of the temperature range,the ramp and the length of a well time and holding time on stress distribution and plastic strain in Sn63Pb37 soldered joint.Also the plastic-strain-based Coffiin-Masson equation is used to analyze the thermal cycling test efficiency and relation of these parameters.The results provide valuable guidance to determine the most efficient temperature profile of the thermal cycling.
