手機鏡頭製程最佳化之改善,經由品管改善手法、PDCA(Plan-Do-Check-Act)手法及各項的改善措施,只能以局部或是一段製程的方式進行改善。使得無法將產品良率提升至更高的目標水準。只有六標準差(6 Sigma)能以全面性之DMAIC流程及手法,將手機鏡頭製程品質更進一步的向上提升。 以六標準差DMAIC之手法為主要架構,利用特性要因圖(Cause and Effect Diagram)對於點膠製程進行分析以及探討,找出影響製程的關鍵因子並且配合變異數理論分析(ANOVA),瞭解製造過程中的參數對於點膠特性的影響。接著以全因子實驗設計進行實驗分析,求得最佳製程參數組合後對製程進行改善。 獲得影響製程能力之關鍵因素及其最佳組合水準,並藉著完整的品質管制策略及作為,掌握關鍵因素的投入,提昇其製程能力。
The process yield rate improvements of Mobile Phone Lens, through quality improvement methods, PDCA(Plan-Do-Check-Act)methods and other improvement solutions, but it is only can be improved partially or a section of the process improvement. Cause the yield rate of product to the target. It only can takes one step ahead to enhance the process yield rate of Mobile Phone Lens with six sigma overall DMAIC process and tactics. Thus, Six Sigma(D-M-A-I-C)will be the main structure of this research. First, use Causes & Effects Chart to analyze and dispensing process; also try to find out the key factor that affects the manufacturing process. Analysis of variance(ANOVA)are employed to investigate performance characteristics during dispensing operations. Second, use full factorial experimental design to conduct experiment, getting the best parameter combination, and improving the manufacturing process. Finally, use Control Chart to monitor the quality after improvement to ensure the effect. To optimum parameter combination and get key factor that have most important influence of quality.
