Description

Gig for slimming glass connected FCP

The present invention relates to a jig for fixing the FPCB when slimming the glass to which the FPCB (Flexible Printed Circuit Board) is coupled, and in particular, the structure preventing the inflow of the etchant into the FPCB during the thinning of the side of the glass. By combining, to prevent the damage of the FPCB by the etching solution, and relates to a glass slimming jig with FPCB coupled to be able to stably fix and mount the glass subjected to the slimming process.

Currently, portable terminals, TVs, and monitors are mainly used as display devices such as liquid crystal displays (LCDs), plasma display panels (PDPs), electroluminescent displays (ELDs), and vacuum fluorescent displays (VFDs).

In particular, there is an increasing demand for flat display devices that are always carried and used by users, such as portable terminals and laptops, and reducing the thickness and weight of such portable display devices has become a major success requirement of the development.

Various methods may be applied to reduce the thickness or weight of the display device, but the structure and the current technology may reduce the essential components of the display device. Moreover, since these essential components are small in weight, it is very difficult to reduce their size or weight.

On the other hand, glass, the most basic component of a display device, has room to reduce its weight as technology progresses. In particular, since glass has the largest weight among the components constituting the display device, studies to reduce the weight of the glass continue.

Reducing the weight of the glass means making the glass thinner. However, when the thickness of the glass becomes thin, the glass is easily broken, and if the glass surface is not smoothed during the processing of the glass, it is very difficult and important in that it causes a serious defect in image quality.

In order to reduce the thickness, that is, the weight of the glass, a method currently used is to immerse the glass in a container filled with etching liquid, and to etch the surface of the glass by the etching liquid. The method of slimming, the method of etching the side surface of a glass, putting a glass upright and flowing an etching liquid from the upper side, etc. are used.

The conventional glass slimming methods are slimming methods for the glass itself or a panel in which the upper glass and the lower glass are bonded. After glass slimming through the above methods, a process of bonding a flexible printed circuit board having a driving circuit or the like to the slimmed glass may be performed.

However, the glass is often broken in the process of bonding the flexible printed circuit board to the slimmed glass. In other words, the glass, which combines the flexible printed circuit board, has a problem of being fragile and difficult to handle because it is in a state of being thinly slimmed.

Therefore, in recent years, a method of bonding a flexible printed circuit board to the glass first and then performing a slimming process has been attempted. However, since the flexible printed circuit board is coupled to the glass, it is difficult to load the glass into a cassette in order to perform a slimming process.

In addition, when the etching liquid flows into the flexible printed circuit board during the slimming process, the flexible printed circuit board is damaged, and as a result, the glass itself or the function of the panel is lost.

Therefore, in order to slim the glass (or panel) to which the flexible printed circuit board is bonded, a jig for effectively loading the glass with the flexible printed circuit board to the cassette and the flexible printed circuit board can be effectively protected in the slimming process. There is a need for a jig. However, to date, when slimming a glass to which a flexible printed circuit board is bonded, there is no proposal for a jig capable of effectively protecting the flexible printed circuit board and effectively fixing and supporting the glass.

The present invention was devised to solve the above problems of the prior art, by combining a structure that prevents the etching solution from flowing into the FPCB in the process of thinning the side of the glass, thereby preventing damage to the FPCB by the etching solution It is an object of the present invention to provide a glass slimming jig combined with the FPCB which prevents and stably fixes and mounts the glass subjected to the slimming process.
