企業要有競爭力,必需仰賴製造技術的不斷改善以及產品品質的提升,因此,如何找出問題的癥結所在,已成為企業競爭的首要課題。在企業資源有限的情況下,本研究的目的是以最少的實驗次數尋求最佳的參數組合,並達到最佳的品質水準表現。 本實驗以LED(發光二極體)產品為案例,並以ITO(Indium Tin Oxide 氧化銦錫)蒸鍍製程為主研究範圍,經由與工程技術人員透過特性要因圖,分析影響LED良率的主要因子,找出影響此製程之關鍵因子,再運用田口博士的參數設計方法從中獲得最佳化的製程參數。最後,以確認實驗來評估最佳因子水準組合之改善成效,做為本研究的佐證依據,並提出未來的研究方向與建議,以提供後續之研究指引。
Be Competitive! - A slogan for every enterprise to strive for the best. How to improve the development process, the manufacturing techniques, and the product quality would be essential issues. To meet the maximum quality with accepted cost, some optimization methods can be used to help practitioners find the solution. This study aims to get Optimum Factor Levels with minimal trial-and-errors so as to provide a better process design for industry. In the study, LED (Light Emitting Diode) product was selected as the topic. We focus on the ITO Electron-beam Evaporator manufacturing process and use Cause-and-effect Diagram to extract the key-factors that dominate the result. Then, Taguchi’s parameter design method is applied to optimize the manufacturing process. Finally, we evaluate and prove the optimum factor levels by confirmation experiments. Implementation results demonstrate a satisfactory result.
