摘要：
Through analyzing TFT-LCD lead open by microscope and SEM & FIB, we find that most of them are caused by electrochemical corrosion. We demonstrate that the crack of the insulator layer during cell and module process is the main reason for the driver electrode erosion. A novel LCD lead area ACF removal process is implemented in module rework process, and we reinforce the module rework adjustment and inspection flow. From the statistical results, the failure ratio of lead open descends sharply and the lead open defects caused by erosion decrease by 498ppm.
