研究表明，有底充胶倒装焊SnPb焊点的塑性应变范围比无底充胶时明显减小，热循环寿命可提高约20倍，充胶后的焊点高度对可靠性的影响变得不明显。

The applicability of this constitutive model is evaluated with the simulations of material tests conducted by Sasaki et al., includes (1)Uniaxially constant strain amplitude cyclic test,(2)Fast in tension/Slow in compression constant strain amplitude cyclic test,(3)Slow-fast-slow constant strain amplitude cyclic test,(4)Cyclic strain with tensile hold time test. Simulations based on this constitutive model have a good agreement with (1),(2) and (3), proofs that it can describe the cyclic stress-strain behavior of 60Sn/40Pb solder very well.

为验证本模式之能力，本文选择Sasaki等人之实验为对象，分别对60Sn/40Pb焊锡在(1)定应变振幅之循环单轴负荷实验、(2)拉伸快/压缩慢之定应变振幅循环负荷实验、(3)慢-快-慢之定应变振幅循环负荷实验、(4)拉伸应力保持之循环应变实验下的材料行为进行模拟，由(1)、(2)及(3)之结果证明本模式对60Sn/40Pb焊锡循环应力-应变整体行为具有理想的描述能力，并对循环塑性应变范围与应力范围之值有准确的预估。
