综述了添加元素对添加Ni、Ge和Bi的Sn1.0Ag0.7Cu钎料蠕变和疲劳性能的影响。元素的加入改善了蠕变性能，但降低了疲劳性能。由此讨论了非比例多轴疲劳试验的必要性。通过将应变检测部分做成空心圆形，研制了一种用于疲劳试验中检测小载荷的高灵敏度称重传感器。通过强度计算，求出满足不考虑高灵敏度也不会产生过度应变的条件的测力传感器的内径和外径。
The effect of element addition on creep and fatigue properties of Sn1.0Ag0.7Cu solder with addition of nickel, germanium and bismuth are reviewed. Element additions imporove creep properties although those deteriorate fatigue properties. From above results, necessity of non-proportional multiaxial fatigue tests are discussed. The load cell with high sensitivity was designed by making to detect small load during fatigue test was developed by making the strain detection part hollow circular. The inner diameter and the outer diameter of the load cell satisfying the condition that excessive strain does not occur regardless of high sensitivity was determined by strength calculation.
