六標準差方法於製程改善之應用 -以SMT錫膏印刷為例
Process Improvement by Six Sigma Approach -A Case study in SMT solder-Paste Print33A8FFD2AE8CD
摘要
近幾年來,六標準差之管理方式盛行於國內外企業界，提高了製造業和服務業之品質。本研究為提升SMT之品質，探討如何以六標準差之管理方式，建立一套SMT品質之管理方式，並以一個案公司所生產之PCB板為例。本研究利用六標準差之DMAIC五大步驟，針對表面黏著技術之錫膏印刷製程品質改善，首先找出關鍵品質特性，求得量測數據之可靠性，並對量測儀器進行量具重現性與再現性之能力分析，在確認製程能力後，歸納找出影響製程的關鍵因子，再利用田口法來進行實驗，找出最適參數組合。 田口法或稱品質工程，係以最經濟的成本及最短的時間，從事產品設計(改良)、製程設計(改良)作業，期使產品能夠充分滿足客戶需求的一套系統性方法。其參數設計又叫穩健設計，具有低成本、高效率的優點，能協助企業做好產品品質設計、管理和改善等工作，進而增強企業的競爭能力。銝

Six Sigma program has been considered as a powerful business strategy that employs a well-structured continuous improvement methodology to reduce process variability and to raise quality within the business process effectively using statistical tools and techniques. This paper presents a procedure that applies six sigma program to improve quality in the manufacturing of SMT. The case illustrates how the define-measure-analyze-improve-control (DMAIC) approach has been used. Firstly, we find out the key factor of the quality characteristic and evaluate the repeatability and reproducibility of the measurement system. After confirming the process of the capability, we find out the key factor, which affects the process, and then use “Taguchi Methods ”to get the ultimate process parameter. Taguchi Methods is also called quality engineering. It is a systematic methodology for product design (modify) and process design (improvement) with the most of saving cost and time, in order to satisfy customer requirement. Taguchi’s parameter design is also known as robust design, which has the merits of low cost and high efficiency, and can achieve the activities of product quality design, management and improvement, consequently to reinforce the competitive ability of business.r
