A Research On Appearance Quality Improvement For HT Memory Module Product

With the rapid development of China's economy,China's science and technology strength has continuous enhancement.Semiconductor industry also made an excellent progress.Regard to the semiconductor industry,besides the need for R&D design capability,manufacturing capacity is also very important.Especially for quality control and management capabilities.The semiconductor industry is a precision manufacturing industry with high requirements of quality.Therefore,management of semiconductor product quality is also a subject worth being studied.Under background of rapid growth of production in HT and the increasingly high demand for product quality in the depressed economic environment,this article takes memory module assembled with DRAM chips as research object to study how to implement a customer oriented lifting scheme of memory appearance quality.This article includes 4 chapters.The first chapter introduces the purpose and significance of the research,the research of quality management at home and abroad,the main content of the this subject.The second chapter makes a brief introduction of HT company and its quality management system.In the third chapter,the production process and the main quality indexes of the memory module products are introduced.The quality problems of HT company and relevant reason analysis is also proposed.The fourth chapter puts emphasis on analysis of the strategy and implementation of customer oriented continuous improvement of appearance quality.Discussing how HT company promotes quality improvement from 3 aspects following,adoption of localization raw materials quality improvement strategy,standardized management of process quality and customer oriented outgoing appearance quality management.By using tools such as brainstorming,5 why,Plato and 5 M1 E,we analyze detail reasons and implement improved measures with PDCA and project management tools.Finally we evaluate the improvement effect,discuss how to implement customer oriented outgoing quality management and how to use PDCA thoughts to promote continuous improvement of HT appearance quality.
