Its efficiency is testified by an application. The fixtureless tester can perform 100% test for PCB's connectivity through the probe movement. It takes a long time to test a PCB with low efficiency.

传统的飞针式在线测试仪必须通过大量的机械运动才能实现印刷电路板连接故障的完全测试，因此完成一块印刷电路板的测试需要较长的时间，检测效率较低。

On the basis of electrical network characterization, Chapter 5 presents a new principle to detect PCB's fault first time. Three methods of online test for electrical network characterization are described in detail. Then, a hierarchical, combinatorial approach is firsfly presented. The test efficiency of this method is studied also. The experiment result shows that the new approach can greatly enhance the test efficiency of fixtureless tester under the requirement of 100% test for PCB's connections.
