热循环寿命评估

检测项目

温度循环次数：记录样品在设定高低温极限间完成完整循环的次数，作为评估其寿命的基础量化指标。

高温保持阶段性能参数监测：在循环周期的高温保温阶段，实时监测样品的电学参数、尺寸变化或机械性能，评估高温下的稳定性。

低温保持阶段性能参数监测：在循环周期的低温保温阶段，监测样品功能是否正常、材料是否脆化或出现裂纹，评估低温适应性。

高低温转换速率耐受性：考察样品对单位时间内温度急剧变化的承受能力，快速温变可能引发热应力集中导致失效。

外观检查与失效分析：在每个预设间隔或试验结束后，通过目视或显微设备检查样品表面是否有涂层剥落、变色、起泡、裂纹等物理损伤。

电气连续性测试：在循环过程中或间隔期，对电子元器件、PCB板或连接器进行导通电阻、绝缘电阻等电气性能测试，判断连接可靠性。

机械性能变化率测定：对比试验前后样品的拉伸强度、弯曲强度、硬度等机械性能参数，计算其衰减程度。
