| Summary: | In this dissertation, the details of design and development of a COG machine that auto-aligns and pre-bonds IC on LCD panel is described. It includes the design of an auto-alignment method and a vision system with two-axis movement to capture the pictures of alignment marks. After the system compares their global coordinates, the positions of IC and LCD are automatically adjusted to match together. Dual bonding head has been developed to handle two different ICs. High precision mechanisms have been introduced for movement and are developed to achieve high accuracy. |
