2、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)質(zhì)問題現(xiàn)現(xiàn)況分析析:月 份-37月-28月-19月010月111月212月31月白 化化不良率率0.05513(5.113%)0.04484(4.884%)0.03324(3.224%)0.03312(3.12%)0.01171(1.771%)0.00025(0.225%)(0指指開始作作專題之之月份)4.製程程說明: 防焊前處處理印印刷預(yù)預(yù)烤曝曝光顯顯影後後烘烤噴錫前前處理IR預(yù)預(yù)熱浸浸Fluux噴噴錫浮浮床噴噴錫後清清洗出出料檢視視因
