3C產品日漸輕薄短小,傳統13”~15”NB常使用的銅釘皆是使用M2.5及M3,但在7”~10”的小筆電因機構結構關係無法使用上述銅釘規格,目前小筆電所採用之銅釘為M2。 本研究計畫將利用六標準差的思維模式在熱熔銅釘製程找出最佳參數以確保所有塑膠柱的銅釘拉力能滿足研發人員設計需求之規格。 本研究先以DMAIC手法找出製程中的問題點,並依據各製程中所會產生的問題點以要因分析(魚骨圖)及Top-Down的方式將流程展開。 The nut for 13”~15” NB is traditionally used with M2.5 and M3 since 3C products tend to be thin and small size. However, the specification mentioned above can not be applied to7”~10” small NB due to the consideration of mechanical structure , hence the Nut M2 is used. In this research , six sigma management is used in hot melting Nut process to obtain the optimal parameters in order to satisfy RD design specification of all pull strength of Nut. The approach of DMAIC can be used to define the problem of the process , measure and analyze the causes, and the improve and control the key process factors. The processes are also developed using the Top-Down way
