摘要:	自二次大戰後的十年是台灣的經濟起飛的轉捩點。而電子製造業正是在這個時期逐漸的發展起來。從七零年代小型的計算機等消費產品起家，到九零年代後期，更是發展出EOM/ODM/OBD的代工模式與研發設計生產及自有品牌的創建，其多項產品跨越全球50%的佔有率。電子製造業的發展史可說是是台灣經濟發展最重要的一項指標。　　本論文研究的目標是以精實六標準差(LSS)來提昇電子製造業中最重要且不可或缺的生產技術SMT(Surface Mounting Technology)之良率為研究的方向。藉由精實六標準的手法來分析SMT製程中的變異點、不良發生原因，進而管控與改良其製程的變數，來提昇其產出的良率。目前本公司所面臨到的問題是由於生產良率之不穩定，而導致後製程產生額外的重工成本與報廢成本。因為SMT是由人員/設備/原物料等三個主要因素所共構而成的製程，如何在透過精實六標準差的方法論，用DMAIC分析其產出不良的因素與過程，並予以改善與追蹤確認，使製程的變異得以管控，以提昇產出良率，降低成本。 The important 10 years after World War II is Taiwan economic growth up period. During this important 10 years, electronics industry rapidly grows up, and expands the enterprise size. At beginning in 1970, electronics industry only produced the simple consumer products as calculator. Till end of 1990, new manufacturing mode had been developed as OEM(Original Equipment Manufacturer)/ODM(Original Design Manufacturer)/OBD(Own Brand Design), some of OBD products were occupied 50% market share on the world. So that, the development of electronics industry is the important milestone in Taiwan economic growth up history. 　　The research object of this thesis is use LSS (Lean Six Sigma) to ramp up the producing yield rate in SMT (Surface Mounting Technology) process that is necessary and key process in almost electronics industries. Through the LSS management method to analyze the various elements, and take actions to improve processing key parameters. The eventually target is control the various elements to ramp up the yield rate. So far, my company is facing a big problem with unstable producing yield rate that make company suffer in extra repair cost and scarp cost within bad products. Due to the construct of SMT process are by three parts, Operator/Equipment/Raw material. How to apply the LSS methodology in SMT process to get the various elements, and take improvement action to control the parameters to aim the yield rate target is the important issue need to solve.
