Description
The present invention relates to equipment for post-processing of Tape Carrier Package (TCP) / Chip On Film (COF).
The wafer manufacturing process of Tape Carrier Package (TCP) / Chip On Film (COF), which is represented by DDI (Display Driver IC), is generally the same as the existing semiconductor chip production process, but the post process is different due to its external characteristics.
In other words, there is a difference in chip bonding and epoxy molding processes, and after the final test process, a visual inspection process is added to the shipment process.
In the production process of the existing semiconductor chip, chip bonding is performed on the wafer using a lead frame, epoxy molding is performed, followed by a marking process, a packaging process through a back end process, and a final test process. Shipped.
On the other hand, in the case of TCP / COF chip bonding to the wafer using a film, the epoxy molding process is processed by a quantitative discharging system, and then subjected to a final test process through a marking process. After that, due to the characteristics of the film, a visual inspection process is carried out to punch out defective products, and then packed and shipped.
The characteristics of the Tape Carrier Package (TCP) / Chip On Film (COF) production method and process arise from the difference between using a lead frame or using a 100M film as a base.
Meanwhile, the final test process and the visual inspection process exist in different processes, and after the final test, the material is moved to the visual inspection process equipment to perform the visual inspection process.
The visual inspection process is a cost increase factor that is made by performing scratch, appearance inspection, foreign matter inspection, etc. manually while viewing an image photographed using a microscope.
Therefore, in order to simplify the manufacturing process of TCP / COF, it is necessary to prepare improvements such as automation of the visual inspection process.
On the other hand, in order to automate the visual inspection process, the distance or angle between two or more cameras and chips must be controlled very precisely, and the difficulty of preventing chip damage or foreign matter from being attached and reeled out during reel delivery In spite of some attempts, there have been no successes.
The present invention has been made to solve the problems of the prior art as described above is to provide a test handling and automatic visual inspection apparatus that can improve the productivity by simplifying the overall process by combining the final test process and the visual inspection process It is done.
Meanwhile, an object of the present invention is to provide a test handling and auto visual inspection apparatus for automating a visual inspection process by precisely controlling the tension of a film throughout the reel winding process.

According to the present invention, the production time is reduced by combining the final test process and the visual inspection process and absorbing them into one process. That is, the productivity is maximized by eliminating the movement and waiting time of the product.
In addition, there is an effect that the visual inspection process can be automated by precisely controlling the tension of the film throughout the reel winding process.
In particular, by allowing the handler part and the auto visual inspection part to be driven partially, maintenance and non-driving time can be minimized.
