Technical Field

The invention relates to a method for manufacturing a COF product, in particular to a method for manufacturing a COF product with a combination mechanism.

Background

With the rapid development of electronics and communication industries, the demand for flat panel displays such as liquid crystal displays, liquid crystal televisions, and plasma televisions is increasing, and the flat panel displays are small and medium sized such as mobile phones, digital cameras, digital video cameras, and other 3C products. These products tend to be thin, light, short, and small, which requires a new generation of packaging technology with high density, small volume, and free installation to meet the above requirements. The COF technology has been rapidly developed under such a background, and has become a main packaging form of a driving IC of a flat panel display such as a liquid crystal display and a plasma display, and has become an important component of these display modules.

When a COF product is connected with a display screen and the like, holes are usually adopted for alignment, and the alignment holes are processed in the COF production process. After alignment by the holes is performed at the time of connection, connection is performed by soldering or ACF. In both of these connection modes, the relative position of the COF and the display is fixed, and some devices are fixed by a suction cup, so that a warping phenomenon may occur in a practical process. Or the positioning hole has an error, so that the connection is low in alignment precision and alignment efficiency, and the overall operation efficiency is affected.
