摘要
介绍了数字电路板故障诊断的一种实用方法。在该方法中，故障检测是基于对电路板的功能测试，故障隔离是基于相关节点的实际响应和预期响应的比较，此外还介绍了诊断数据库的建立方法以及测试系统的硬件组成。根据这一方法已研制成功一个实用测试系统，它能把８０％故障隔离到节点。
practical method for fault diagnosis of digital circuit boards is presented.In this method,fault detection is based on functional test for circuit boards, and fault isolation is based on the com- parison of actual response and expected response on correlative nodes,Besides, the aproach of building diag- nostic database and hardware composition of test system is introduced,According to this method,a practical test system has been made successfully.it can isolate 80% faults to nodes.
