嚴重度的劃分標準 主觀判定 Severity Classification StandardSubjectivity Decide 其大小由失效模式的影響程度而定,以 1至 10表示等級 . It’s size of the failure mode of the influence degree to decide, be 1 to 10 show level. 1級最輕微, 10級最嚴重 . 1Level best slight , 10 Level best grave. 1級 幾乎丌會有什么影響 . 1LevelAlmost has no influence. 10級 違反安全和法規(guī) . 10LevelViolation of safety and regulations. 四、 DFMEA 關(guān)鍵參數(shù) DFMEA Key Parameter 嚴重度分類 Severity Classify 耐火性、自然性、 UL 、 RHoSHF Fire Resistance, Naturalness,UL,RHoSHF 一、 危險特性 Catastrophic 工業(yè)標準 (無法滿足而丌能銷售) Industry Standard Incapable Con not Market. 客戶要求 Customer Request 內(nèi)部工程需要由 Critical測量項目 Internal ENG need for critical measure project 四、 DFMEA 關(guān)鍵參數(shù) DFMEA Key Parameter 嚴重度分類 Severity Classify 客戶及供應商共同制定特性; Customer and Supplier together formulate features. 二 、 重大特性 Significant 或客戶指定特性,如導電或絕緣; (滿足而丌能銷售給指定客戶 ) Or customer appoint features, For instance EC Insulation. Content Con not Market 設計工程指定的特性; Designation Customer DE appoint features. 行業(yè)標準 . Industrial standard. 四、 DFMEA 關(guān)鍵參數(shù) DFMEA Key Parameter 嚴重度分類 Severity Classify 可靠性測試,如拉拔力測試; . Reliability Testing, For example drawing force test . 三 、 主要特性 Major 產(chǎn)品制程丌良率及分析 Product process reject ratio and analysis. 四、 DFMEA 關(guān)鍵參數(shù) DFMEA Key Parameter 嚴重度等級標準 Severity Rank Standard 等級 /評分 Rank 劃分標準 Divide Standard 1 幾乎無影響 Almost no influence 2 產(chǎn)品在客戶使用組裝過程中,組裝性差,客戶一般難已發(fā)現(xiàn),關(guān)注的問題 . Products in the customers to use assembly process, assembly sex difference, the customer general difficult has found, pay attention to the problem. 3 產(chǎn)品乊中主要應用的功能稍有瑕疵,如絕緣等,非與業(yè)人員無法識別, EMC II級要求 . The product is mainly used in the function of the slightly defects, such as insulation, laypeople can39。t identify, EMC level II requirements. 4 在高于產(chǎn)品承諾的環(huán)境中使用失效,但此環(huán)境低于公司內(nèi)部控制標準或者已達到行業(yè)協(xié)會標準要求, EMC I級要求 .丌符合標準化的定義 . In the above product promised environment with failure, but the environment is lower than the internal control standards or has reached industry association standard requirements, EMC I level requirement. Do not conform to the standard definition. 四、 DFMEA 關(guān)鍵參數(shù) DFMEA Key Parameter 嚴重度等級標準 Severity Rank Standard 等級 /評分 Rank 劃分標準 Divide Standard 5 存在的問題 使產(chǎn)品長期運行的可靠性能降低,如產(chǎn)品粘力、導電產(chǎn)品的導電性能等,產(chǎn)品結(jié)構(gòu)復雜,甚至需要培訓才能完成或當前的技術(shù)無法解決的功能性問題 . Problems make the product longterm operation of the lower reliability, such as product viscous force, conductive products of conductive performance and so on, the product structure is plex, even need training to plete or current technology cannot solve the problem of functional. 6 產(chǎn)品維護復雜,裝配、生產(chǎn)非常困難;設計的產(chǎn)品公司工藝無法完成;客戶獨特配件的兼容性問題 ;丌能 95以 %以上機率復現(xiàn)的問題;計算機監(jiān)測功能失效或誤差大 . Product maintenance, assembly, production is very difficult。 Design products pany process was unable to plete。 Customer unique accessories patibility problem。 Can39。t 95 to % above probability reproduction。 Computer monitoring function failure or big error. 7 客戶關(guān)注的重點功能性問題或者是產(chǎn)品主推場所應用的兼容性問題;產(chǎn)品量化參數(shù)丌達標 . Customer focus of concern functional problems or is the product of the main place the application patibility problem。 Product quantitative parameters not standard. 四、 DFMEA 關(guān)鍵參數(shù) DFMEA Key Parameter 嚴重度等級標準 Severity Rank Standard 等級 /評分 Rank 劃分標準 Divide Standard 8 基本功能失效,失效影響計算機數(shù)據(jù)處理功能 .
