Quality Management Improvement Of N Semiconductor Raw Material Company

Semiconductor industry is Capital and technology-intensive industry with high investment in machinery and equipment,complex processes and high product reliability requirements.Therefore,the quality management of semiconductor supply chain is extremely important and difficult and has its own characteristics.N Semiconductor Materials corporation is a manufacturer of lead frames for semiconductor.Its products mainly focus on mid-low-end market.The products are mainly used in consumer electronics.Its customers are primarily semiconductor packaging companies in China.Its customers are primarily semiconductor assembly companies in China.Due to business development,it plans to enter the automotive supply chain and provide products for foreign customers.Therefore,it is necessary to further improve the product qualification rate,reduce customer complaints,and improve the level of quality management.The thesis analysis customer complaints and the product quality data,use Plato and Fishbone diagrams to analyze problems.Then implement VDA6.3 process audit,to assess quality management system,and summarize the non-conformities to reveal the systematic problem and root cause.Use process method “Turtle mode” to improve on process support,process work content and process material resources.Process support is mainly to define and improve the human resources training mechanism;process content focuses on incoming check process,statistical process control,out of control action plan(OCAP),and equipment preventive maintenance;process resources are to automatically detected through the introduction of automatic optical inspection equipment for key dimensions,to timely find problems and effectively prevent failure escape to customers.Through above improvements,employees' quality awareness and skill will be enhanced,process capability and sustainability will be improved,then to improve qualified rate,reduce customer complaints,and improve quality management.
