| Summary: | 碩士 === 明新科技大學 === 工業工程與管理系碩士班 === 102 === The thin-film transistor liquid crystal display (TFT-LCD) is one of the important industries in Taiwan. However, due to the highly competitive pressure from the other manufacturers worldwide, to stand out from the competitive reality, there should be good quality and first-class factories as the backend supports. The availability of complete production process planning, excellent and well-trained personnel, and stability and manufacturing equipment utilization rate, are also recognized as the key important factors.
This research focuses on six sigma of the DMAIC approach in TFT-LCD plant preventive maintenance, promote stability and utilization rate of equipment, product has stable yield and productivity promotion, to batten down the hatches of the spirit, develop the desired quality level.
This study will apply the “Failure Mode and Effects Analysis” (FMEA) model for various stages of the early production phase, analyze the impact of the potential failures of equipments, distinguish and explore the models for different possible severity levels, and be able to take the appropriate preventive maintenance strategy. For the range of higher severity and critical levels, the proposed method can be used to prevent the occurrence of the potential failures, and reduce the impact caused by the failures, so that the effective control policies can be established during the mass production phase, to promote the reliability of the process equipments.
