文档介绍：: Failure Mode Effects Analysis 失效模式效应分析(FMEA)
(see IEC 60812 见 IEC60812)
Evaluation of potential failure modes for processes
The likely effect on es and/or product performance
Once failure modes are established, risk reduction can be used to eliminate, reduce or control the potential failures
FMEA relies on process understanding
Summarize the important modes of failure, factors causing these failures and the likely effects of these failures
How to perform?Break down plex processes into manageable steps
ICH Q9
: Failure Mode Effects Analysis 失效模式效应分析(FMEA)
(see IEC 60812 见 IEC60812)
工艺的潜在失效模式的评估
对结果和产品性能的可能的影响
一旦失效模式建立,风险降低行动用于来消除、降低或控制潜在的失效
依赖于对工艺的理解
概述重要的失效模式,引起失效的因数和失效的可能的影响
如何实施?将大的复杂的工艺分解成易处理的步骤

ICH Q9
: Failure Mode Effects Analysis (FMEA)
How to perform?
1. Establish a team
2. Identify the known and potential failure modes:
Develop lists of known problems and brainstorm other potentials….
Product not meeting specification
Process not meeting yield requirements
Malfunctioning equipment
Software problems
Newly identified failure modes should be added at any time
EXAMPLE
: 失效模式效应分析(FMEA)
如何实施?
1. 成立一个小组
2. 识别已知和潜在的失效模式
生成已知问题和集体讨论的其他潜在问题的列表
例如.
产品不符合标准
工艺不满足收率需要
设备故障
软件问题
新发现的失效问题应该随时加进来。
