Research on fault prediction and diagnosis method of PCB circuit

With the rapid development of contemporary PCB circuits, circuit complexity continues to increase, which puts forward higher requirements for the reliability of PCB circuit operation. The fault prediction and diagnosis of PCB circuits have attracted widespread attention from scholars at home and abroad. PCB circuit is a kind of analog-digital mixed circuit including digital circuit and analog circuit, and circuit failure prediction is mainly used in analog circuit part. This article mainly analyzes three parts: PCB digital circuit fault diagnosis, PCB analog circuit fault prediction and PCB analog circuit fault diagnosis.
