Description

Film guide apparatus

The present invention relates to a film guide device.

In recent years, miniaturization, thickness reduction, and weight reduction in electronic devices such as mobile phones, portable information terminals, liquid crystal display panels, and notebook computers are progressing. Accordingly, miniaturization, weight reduction, high functionality, high performance, and high density of various components, including semiconductor devices mounted on these devices, are progressing similarly.

That is, as flat panel displays such as LCD, PDP, and LED capable of reducing weight and thickness have been developed, weight reduction and thinning of display components required therefor have been demanded. The semiconductor components used for these are also configured in a package to pursue weight reduction and thinning of such flat panel displays.

For example, a tape carrier package can make a large number of signal input/output terminals even in a limited area compared to a conventional semiconductor package, and by using a thin flexible tape, it becomes less restricted by the package shape or location. It is a next-generation semiconductor package technology that can pursue miniaturization, high integration, and multi-pin. Examples of such a tape carrier package include Tape Automated Bonding (TAB), Chip On Film (COF), or Flexible Ball Grid Array (Flexible BGA).

The tape for such a tape carrier package is supplied and discharged in the package manufacturing process in a reel-to-reel method.

In particular, when conveying the tape through the conveying path, the guide roller installed on the conveying path through which the tape passes is used to create a certain tension in the tape located between the guide and the roller or to guide the tape so that it does not deviate from the conveying path. plays a role

However, since direct contact between the film and the guide roller is made in the process of loading, unloading, and transporting the film for the process, there are various problems such as damage to the film or attachment of foreign substances from the equipment.
