The Study Of Six Sigma Management In Wafer Visual Quality Control

Solid state drives Attract Customers’ attention because of its high speed and excellentproperties,Thus causing great conflicts to the traditional hard disk.And S company as thelargest supplier of disk heads is facing a huge test.Compared with the traditional solid statedisk, hard disk has the advantage of low cost.How to keep the high quality, low costadvantage has become one of the key development of S company.The fast development of global economy integration is driving electronic industryincreasingly fierce market competition.The enterprise competition has changed from productquantity and price competition to product quality and brand competition.Many enterpriseshope to use Six Sigma management method to improve the quality and reduce productioncost.Six Sigma system take customer as the center and is a strategy for continuousimprovement.It is based on the data, through the analysis and judgement on the data to findthe problem that is hidden.And optimization process base on the analysis of the relationshipbetween input, output of process. it aimed at reducing the defect, improving the qualified rateand customer satisfaction, then increase in net income.With the visual defect rate of wafer supplier improvement for the case to study the modeand methods of Six Sigma management to control product quality.With implementing the sixsigma DMAIC and using of the appropriate tool(such as aton method, tree, fishbone, causalrelation matrix and hypothesis testing, the method of DOE),we get the direction ofimprovement and optimization results,then to solve the problem of poor quality,and to reducethe cost of poor product,and to improve operator work quality and efficiency,to furtherimprove the operational efficiency of enterprises, reduce the production cost.The success of the case that apply Six Sigma to improve supplier product quality is notonly application of techniques and methods,but also research of new management mode.Thecase has a good reference for electronic products supplier quality management.
