2、出出現(xiàn)瑕疵疵，使得得客戶產(chǎn)產(chǎn)生疑慮慮，甚至至不允收收。所以以利用DDOE的的手法找找出最佳佳生產(chǎn)條條件，以以降低防防焊油墨墨在噴錫錫後產(chǎn)生生白化現(xiàn)現(xiàn)象。 3.品質(zhì)問問題現(xiàn)況況分析: 月 份-3 7月-2 8月-1 9月0 10月1 11月2 12月3 1月白 化 不良率率0.05113 (5.13%)0.04884 (4.84%)0.03224 (3.24%)0.03112 (3.12%)0.01771 (1.71%)0.00225 (0.25%)(0指開開始作專專題之月月份) 4.製程說說明: 防焊前處理理印刷刷預(yù)烤烤曝光光顯影影後烘烘烤噴噴錫前處處理IIR預(yù)熱熱浸FFluxx噴錫錫浮床床噴

3、錫錫後清洗洗出料料檢視因本廠出出現(xiàn)防焊焊白化以以Currtaiin CCoattingg比例較較高，因因此選擇擇以Cuurtaain Coaatinng印刷刷方式找找出白化化成因。 5.特性要要因分析析: 6.第一階階段實驗驗配置及及解析: 6.1實驗驗因子及及水準(zhǔn)對對照表:6.2配置置方式及及交互作作用: 6.2.11採L116215方式式配置 6.2.22點線圖圖:6.3實驗驗解析(1)白化化 6.3.11防焊特特性(11)白化實實驗配置置及數(shù)據(jù)據(jù): FACTOORABABFIDADCACeGHAHIGFGDATAROW/CCOL123456789101112131415311111111
