本文讨论了特征分析技术的特点。这种技术操作简单,能提供元件级的现场修理,故障检出率可高达99.998%,因而它是目前数字电路现场维修中最有发展前途的一种技术。本文还从理论上证明了故障检出率高的原因,并介绍了特征分析技术的设计准则。
This article discusses the characteristics of feature analysis techniques. This technology is simple to operate and provides on-site component-level repair with a 99.98% failure detection rate, making it the most promising technology in on-site maintenance of digital circuits today. The paper also proves the reason of the high detection rate in theory and introduces the design criteria of feature analysis technology.
