Abstract:
Method and system for performing close-loop analysis to electronic component failures are provided. The system establishes an electronic component fault tree of physics of failure (FTPF), converts the FTPF into a failure locating fault tree, establishes an electronic component fault dictionary with the cause of failure mechanism corresponding to failure characteristics, and performs close-loop analysis to the electronic component according to the fault tree and the fault dictionary. According to the disclosure, it is possible to locate the electronic component fault in the internal physical structure by the failure locating fault tree, to give a clear failure path, to quickly identify the failure mechanism corresponding to the electronic component failure mode by analyzing the failure characteristic vector in the fault dictionary, and to determine the mechanism factors and influencing factors of relevant failure mechanism by the FTPF, thereby achieving fast and accurate locating and diagnosis for the electronic component failure.

Claim (Index 7):
The system of  claim 5 , wherein the failure locating fault tree establishing module further comprises:\n an event converting unit, configured to determine an observable node between a failure mode and a failure mechanism, and to represent an immeasurable event of physics of failure by an observable node event; a characteristic parameters selecting unit, configured to select, according to the structure and performance characteristics of the electronic component, observable characteristic parameters representing each node, including: electrical, thermal, and mechanical properties, appearance characteristics, hermeticity, and environmental adaptation; a parameter representing unit, configured to represent an electronic component failure event by a node failure event, and to represent the node failure event by the observable parameters; and a fault tree establishing unit, configured to establish an failure locating fault tree of an electronic component, the failure locating fault tree having the failure mode as top event, the observable node as intermediate event, and the failure mechanism as bottom event.
