摘    要:在装备生命周期的各阶段,其承受的环境载荷都可能对装备造成累积损伤,进而引发故障。从装备设计特性和寿命期环境应力分布及其相互作用角度来分析装备的故障更符合其未来实际使用情况。介绍了电路板常用的故障物理模型,阐述了基于故障物理的电路板可靠性分析流程,明确了潜在故障仿真思路,为装备早期可靠性设计、测试性设计与评价提供了方法依据。

关 键 词:环境载荷  故障物理  可靠性分析  测试性设计

Abstract:At every stage of life cycle, environmental loads may cause cumulative damage to the equipment, and then caus- ing fault. It is in accord with the actual usage in the futurc for equipment to analyze its faults from the angle of the design feature of equipments, longevity environment stress distribution and the interaction between them. The common fault physi- cal models of circuit boards were presented, and the circuit reliability analysis process based on physics-of-failure (PoF) was expounded. The simulation method of potential fault was expatiated. A feasible method was provided for the early eval- uation and design for reliabLlity and testability of equipment.
Keywords:environmental load  physics-of-failure  reliability analysis  design for testability
