A Modified FTA-FMEA Methodology: An Application for CNT-BLU of TFT-LCD

Both new technology and new product improve the customerspsila satisfaction. Carbon Nano-tube Back Light Unit (CNT-BLU) is a new product which uses CNT in the design of the back light unit for TFT-LCD. However, there are many problems with this new technology. The processes of determining the causes of the manufacturing process problems usually take considerable time when the problems occur. The objective of this study is to propose a modified FMEA which integrates FTA, Cause and Effect Diagram, FDM. We presented step-by-step procedures to perform process analysis for CNT paste printing problem in the production of CNT-BLU. After conducting a real-word case analysis, we found that results coincide with the consensus of experienced experts. It shows that the proposed methodology is a useful tool for failure analysis in the analysis of CNT-BLU manufacturing process problems. Furthermore, this method can also be applied to the related fields of failure analysis.
