GRR(Gauge Repeatability and Reproducibility)和NDC(Non-Destructive Testing)都是用于评估测试过程的标准值。 GRR是一种用于评估测量仪器的重复性和再现性的方法。它的目的是确保测量结果的准确性和一致性。GRR标准值是在特定条件下,由多个测量人员在相同的条件下获得的测量值的平均值和标准偏差。这些值用于评估测量...
NDC(Non-Destructive Testing 或 Number of Distinct Categories)在不同领域中具有不同含义。在质量控制领域,它通常指测量得到数据分组的数量值大小的代码,反映了测量设备的分辨力。NDC标准值也是在特定条件下,由多个检测人员在相同条件下获得的检测结果的平均值和标准偏差,用于评估检测仪器...
A handler is used to automatically move semiconductor devices from a device tray or other storage device into position for testing. When operating in a GRR mode, the handler is configured to place each of the semiconductor devices being tested in each possible testing position. A series of ...

在集成电路测试数据分析中,有两种使用GRR分析的方法。一种是同一个器件,验证不同的配置下,测试结果是一致的。这种就是单因素方差分析法。因为是同一个器件,所以H0假设是均值相等。因为是同一套系统,可以认为标准差相等。所以,这种情况要求不拒绝H0假设,也就是计算出来的F比值要小于Fα的值,即不拒绝均值相等的假设...
