目前台灣連接器產業，所遭遇最大的挑戰，為開發時程過長及品質成本腐蝕產品毛利。過去連接器產業憑藉傳統產業的思維，一昧地朝降低產品製造成本來提升毛利，而忽略品質成本及其他間接成本。本研究為一實際的個案研究，造成公司高品質成本的主因在於製程參數設定不佳，導致產品品質不穩定，當產品量產之後，在客戶端不斷產生產品異常，因此品質成本也跟著高漲，腐蝕產品毛利。本研究主要是希望透過目前電子產業廣為使用的六標準差的DMAIC手法，找出影響製造連接器的可能控制因子，並透過田口方法找出控制因子最佳水準，來提升品質、降低成本並增加獲利。在個案公司六標準差專案小組成功地運用DMAIC手法之後，有效地控制造成品質不良的因子，可提升製程良率達98.52%，讓個案公司節省上千萬元的品質成本。

Now Taiwan connector industry which suffered the greatest challenge for the development time is too long and the cost of corrosion product quality margin. In the past, the connector industry applied traditional thinking to indiscriminate reducing the manufacturing costs for improving profit margins, while ignoring the Cost of Poor Quality and other indirect manufacturing coasts. This is a practical case. The root cause which causes to high Cost of Poor Quality is in poor process parameter settings. The reason resulted in unstable product quality as well. When mass production, there are many of abnormality were produced in the client side. So that, high Cost of Poor Quality was rose and profit margin was affected as well. The study through the DMAIC approach of Six Sigma that it was applied in the electronic industry currently to find out the factors which impact Cost of Poor Quality of connector manufacturing. BTW, it applied the Taguchi methodology to find the best levels of control factors and improve Cost of Poor Quality and increase profit margin. In this case, the Six Sigma team applied successfully DMAIC approach in controlling effectively the factors which cause to poor quality and yield rate was enhanced to 98.52%, this way helped company in the case study to save ten millions of Cost of Poor Quality.
