TFT LCD

The ITO line AOI inspection machine (also known as the step electrode automatic inspection machine, terminal scratch automatic inspection machine) is mainly used for defect detection of ITO in the exposed area of TFT-LCD lines, improving production line yield and the process control capability of manufacturers. Mainly detecting scratches, short circuits, open circuits, micro breaks, foreign objects (dirt), corrosion, burrs, etc. The equipment can be widely used in fields such as TFT-LCD industry, touch screen industry, photovoltaic industry, and LED industry, achieving rapid detection of ITO lines, silver paste lines, etc. on glass substrates or flexible substrates (PET, CPI, etc.).
