PSH/SQQ Annex I.2 Failure Mode Effects Analysis 失效模式效应分析 (FMEA) I.2: 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 outcomes 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 large complex processes into manageable steps I.2: 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 I.2: Failure Mode Effects Analysis (FMEA)  Potential Areas of Use(s) Prioritize risks Monitor the effectiveness of risk control activities Equipment and facilities Analyze a manufacturing process to identify high-risk steps or critical parameters I.2: 失效模式效应分析 (FMEA)  可使用的潜在领域： Prioritize risks优先考虑的风险 Monitor the effectiveness of risk control activities监控风险控制活动的效力 Equipment and facilities 设备和设施 Analyze a manufacturing process to identify high-risk steps or critical parameters为了识别高风险步骤和关键参数分析一个生产工艺 I.2: 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… e.g. Product not meeting specification Process not meeting yield requirements Malfunctioning equipment Software problems Newly identified failure modes should be added at any time I.2: 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。 I.2: Failure Mode Effects Analysis (FMEA) How to perform? 3. Characterise the severity, probability and detectability An equal number of levels is sometimes helpful Some preference
