摘要: 文章研究了印制电路板(PCB)网络点集合分割算法,提出了网络集加激励产生响应的测试算法,给出了基于该算法的测试逻辑电路和控制流程图。实践表明,该算法较好地解决了网络点数与测试速度的矛盾,是快速检测PCB短路故障的一种有效方法。Abstract: The paper studied a segmentation algorithm of PCB network set, put forward a test algorithm based on response from stimulation to the network set, gave the test circuit and control flow charts based on the algorithm. The practice proved the algorithm can well solve the contradiction between speed of detection and number of network points, which is an effective and rapid way for detection of the PCB′s fault caused by short circuit.
