Study of Good Yield and Efficiency in TFT-LCD Module Process
This paper introduces the TFT-LCD (Tablet Film Transistor Liquid Crystal Displayer) module process that is composed by two stages, JI (JISO) process and MA (Module Assy) process. In JI process, the main defect phenomena are bonding particle and bonding defect, which have a bad effect on the product yield. In MA process, the key factor of the output is the inequality workload to every worker and unbalance of the production line. With the solution of plasma cleaning and pressure diversification, the bonding defect ratio descent from 0.34% to 0.14%. By making workload balance, the efficiency of MA process has been increased.
