一种数字电路板测试诊断系统的设计

Design of An Electronic Circuit Board for Test and Diagnosis System

对于国外引进的自动化系统和设备,需要大量的替代和备用数字电路板件,为提高数字电路板加工的正确性和工作效率,给出数字电路板测试诊断系统的设计方案,介绍测试诊断系统的主要组成,分析功能测试法的工作原理,从而判定被测试样本的逻辑功能是否正确,并展望测试诊断系统的应用前景。

Towards imported automation system and equipment, it needs a lot of replacement and spare electronic circuit boards. In order to improve the accuracy and efficiency of the electronic circuit board manufacture, this article gives the designing scheme of electronic circuit board test and diagnosis system and introduces the main components of this system. It analyzes the theory of function testing to judge the logic function of the tested equipment and outlooks the application prospect of this system.
