A Research On Six Sigma Applied For Quality Improvement Project In J Company

In recent years,the global economy continues to decline,the demand for electronic products has gradually slowed down,leading to the electronic foundry industry competition is becoming increasingly fierce,the electronic manufacturing industry is facing the transformation.J company as a liquid crystal module industry followers are facing more and more pressure to survive.Continuously reduce costs and improve production yield is the most important performance evaluation index of J company's production and profitability.And the Six Sigma approach is to help J companies to achieve cost and quality of the advanced management model.Firstly,this paper studies and studies the origin,development and theoretical basis of total quality management,and then expounds the inheritance and development of the Six Sigma.Summed up a suitable J company's Six Sigma quality management model.Then,in order to improve the quality of new product launch yield is too low for the actual case,the application of Six Sigma theory,the use of DMAIC method of new products of the poor rate in a limited period of time reduced from 1.79% to 0%.First of all,to analyze the defect rate,from the improvement of the choice of the project,the analysis of the phenomenon,and the process flow chart analysis.And then the measurement system analysis,confirmed the accuracy of the measurement system;improve the stage in the analysis,to verify the potential factor,then DOE optimization of significant factor;in the control stage,to determine the effective action to improve standardization,consolidate the improvement,to ensure the sustained and effective measures.Through the practice of this improvement project,the practical value and effect of the Six Sigma Theory in J company are verified.In order to help J companies continue to reduce costs and improve production yield,in order to improve the efficiency of J company's management and profit margins.At the same time hope to become an electronic factory to improve the quality of the factory to provide a reference.In order to reduce the cost and improve the production yield,but also to ensure to provide high quality products and services to customers,the use of Six Sigma management method more and more electronic industry managers,bring huge benefits for the company and bring more business opportunities.
