中文摘要

在現今社會的大環境裡,綜觀企業的經營與管理,成本、生產力與品質這三者對企業的獲利皆能有所貢獻,但在目前的競爭氛圍下,顧客已不再只會因為企業的「低成本」、「高生產力」就購買其所提供的產品或服務。顧客在意的是品質的問題,因此如何做好品質管理是非常重要的課題。而在眾多品管方法中,六標準差是其中相當流行、且已有許多成功案例的一種品質改善手法,例如:奇異、摩托羅拉,六標準差對於降低公司內的浪費與提高品質已經有顯著的效果。
本研究將六標準差中的DMAIC改善手法應用於個案公司中,提高了關鍵製程電鍍站的良率。在定義階段深入了解來自品保部門提供的客訴案例,並成立了跨部門的專案小組來著手改善;於衡量階段則是透過Kappa分析法確立廠內檢測手法與客戶定義相同,並整合各方資源進行目前的製程能力探討;接下來就於分析階段採用特性要因圖來解析良率低落的原因並於改善階段予以逐一矯正,最後於控制階段證明了電鍍藥液濃度與鍍層厚度間的關係,並使用管制計畫表、FMEA及SPC管制圖來持續維持品質的精進。

關鍵詞:六標準差、DMAIC、電鍍、管制計畫表
Abstract

Considering business management in the modern society, cost, productivity and quailty are all crucial to the profitability of a corporation. However, in the current hyper-competitive environment, customers rarely choose a product or service from a business simply because of its low cost or high productivity; very often, quality is now the customer’s top concern. Therefore, quality control is of utmost importance to a modern business manager. Among the many methods of quality control, “Six Sigma” is a popular strategy, and it has been proven by many successful examples; corporations such as GE and Motorola have already shown that the “Six Sigma” method could significantly reduce waste and increase product quality in the organizations.
In this research, “DMAIC”, part of the “Six Sigma” quality control strategy, was applied to an index business, and it improved the yield of a plating process crucial to a manufacturing process. First, during the define period, the customer complaints collected by the quality assurance department was thoroughly investigated, and an inter-department task force was set up to create an improvement strategy; in the measure period, the kappa method was used to confirm that the testing method used in the factory was identical to the customer’s definition, and multiple resources were integrated to re-examine the production process; in the analyze period, the cause of the low yield was dissected using the cause & effect diagram, and the identified factors were corrected in the improve period. Finally, in the control period, it was proven that the concentration of the chemicals in the plating solution was related to the thickness of the plating, and control plan, FMEA and SPC control plan are utilized to maintain the improvement in the production quality.

Key words: Six Sigma, DMAIC, Platting, Control Plan
