Abstract

The present invention relates to a tray for a flexible substrate. More specifically, when a sheet-type flexible substrate formed of a flexible material is fabricated, a semi-dried flexible substrate stacked on the tray may be safely carried in the process of carrying a semi-dried product by including an exposure process utilized in a photo solder resist (PSR) process. In particular, according to the present invention, when the semi-dried flexible substrate is stacked on the tray in a slit form, at least two edges are supported to the stacked flexible substrate, thereby preventing the stacked flexible substrate from being bent due to inertia or an external impact resulting from the movement and the stop of the tray, and preventing exposure ink from being deformed or damaged due to the contact between adjacent flexible substrates. Accordingly, the reliability and the competiveness can be improved in an exposure technology field employing a maskless scheme based on laser direction imaging (LDI) and a printed circuit board (PCB) process field using the exposure technology field, a PSR process field, a flexible substrate fabricating field, a tray field for carrying a flexible PCB, and a filed similar to or associated with the above field.

Description

{Tray for flexible substrate}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flexible substrate tray, and more particularly, to a flexible substrate tray, which comprises an exposure process used in a PSR (Photo Solder Resist) process or the like during the manufacture of a flexible substrate of a flexible material, So that the semi-dry flexible substrate loaded on the tray can be safely transported during the transportation of the product.

More particularly, the present invention relates to a flexible substrate which is semi-dried in the form of a slit, which is supported on at least two edges of the flexible substrate, The present invention relates to a flexible substrate tray capable of preventing the substrate from bending and preventing deformation or damage of the exposure ink due to contact between adjacent flexible substrates.

In recent years, as our living environment has entered the ubiquitous era, mobile devices such as smart phones and various electronic products have been made into a small quantity and a variety of products. In order to manufacture a high-density circuit due to high functionality, A technology capable of realizing the above-mentioned technology is required.

Accordingly, new exposure methods have been developed to realize ultra-fine line widths on printed circuit boards (PCBs), and maskless methods using LDI (Laser Direct Imaging) have been developed.

LDI is used in a PCB printing process and a photo solder resist (PSR) process by directly exposing a substrate to a pattern without using a photomask. Since LDI uses light, it forms a circuit of an ultra-fine line width It is possible to realize a variety of circuits by merely changing the exposure pattern, so that it is possible to make a variety of products possible.

As a result, it is possible to form a pattern requiring high resolution, and it is a technology capable of flexibly coping with a mass production system as well as a small quantity production of a variety of products.

In addition, since LDI is a technique for forming a PCB circuit or a solder resist layer through an exposure process for irradiating light, the position of the substrate from the origin where light is emitted and the distance from the substrate must be maintained constant, And the thickness of the exposure ink must be kept constant to perform accurate exposure, thereby producing a product of sufficient quality.

On the other hand, in the PCB printing process and the PSR process, the semi-finished product after each process is moved to the next process using the tray.

An example of such a tray is disclosed in Korean Patent Registration No. 10-1580901 entitled " Prior Art ", which is hereinafter referred to as " Prior Art ".

However, it can be easily seen that the prior art trays are more suitable for transporting certain standard products, such as wafers or semiconductor devices, and are not suitable for transporting different products produced in small quantities in a single line.

In particular, recently produced substrates use mainly a flexible sheet-type flexible substrate, and since such a sheet-shaped flexible substrate is not suitable for using a tray of the same type as the prior art, Or horizontally stacked horizontal trays.

At this time, when the exposure ink semi-cured on both sides of the sheet-like flexible substrate is applied, deformation may occur in the exposure ink on one side when the horizontal tray is used, so that most vertical type trays are used.

Briefly, a currently used vertical tray is configured such that slits are formed on both sides of a frame forming an outer shape, and both side edges of the sheet-like flexible substrate are inserted into slits.

In the case of such a vertical type tray, since the both side edges of the flexible substrate are inserted into the slit in a state of having fluidity, contact with the adjacent flexible substrate may occur due to inertia due to movement and stop during transportation.

When the contact with the adjacent flexible substrate occurs in this way, the semi-dry exposure ink having the two flexible substrates formed thereon comes into contact with each other, which may cause deformation or damage to the exposed ink.

Particularly, when a large-area flexible substrate is manufactured for the purpose of improving productivity, such a contact phenomenon is more frequently generated.

The lower support rail 300 is fixed to the lower portion of the base frame 100 and can be fixed to the support frame 110 formed at the lower portion of the base frame 100. As described above, The lower portion of the flexible substrate fs can be inserted and supported in a sliding manner by the movement of the flexible substrate fs. Hereinafter, how the lower support rail 300 supports the lower portion of the flexible substrate fs will be described with reference to a specific embodiment.

As a result, the upper and lower portions of the flexible substrate fs can be fixed to the tray and stably supported by a simple operation using the flexible substrate tray A shown in FIG. 1, (fs) can be safely transported.

FIG. 2 is a view showing a specific embodiment of the upper support rail of FIG. 1. FIG.

First, most of the flexible substrates fs are formed with a plurality of holes (not shown) at the edge portions for various reasons such as alignment and support of the flexible substrate fs in the process of passing through each process.

In other words, the holes formed in the edge portions (portions irrelevant to the pattern formation) of the flexible substrate fs are indispensably formed in the process of manufacturing the flexible substrate fs. When such holes are used, the flexible substrate fs It is not necessary to add a separate process for mounting the wafer.

Referring to FIG. 2, the upper support rail 200 may further include a support hook 230 coupled to a hole formed in the upper edge of the flexible substrate fs.

The support hook 230 is formed on the movable rail 220 of the upper support rail 200 and can be coupled to move along the one side of the movable rail 220 in the longitudinal direction.

In other words, the support hook 230 can adjust the distance and position between the support hooks 230 while moving the support hooks 230 in the longitudinal direction of the upper support rail 200, corresponding to the positions of the holes formed in the flexible substrate fs.

Here, the structure in which the support hook 230 is movably coupled to the movement rail 220 can be applied to various forms such as a groove and a rail, and can be modified according to a demand of a person skilled in the art. Do not.

FIG. 3 is a view showing another embodiment of the upper support rail of FIG. 1, and FIG. 4 is a view for explaining a function of a one way clip shown in FIG.

3, the upper support rail 200 of the present invention can form a one way clip 240 on the movable rail 220 to support the upper portion of the flexible sheet fs.

The one way clip 240 is configured so that the direction in which the flexible substrate fs is sandwiched and the direction in which the flexible substrate fs is pulled out are different from each other. The flexible substrate fs is sandwiched in one direction (upward direction in FIG. 3) 3), and can be separated in the other one direction (the lower right direction in Fig. 3).

In other words, the one-way clip 240 can support the flexible substrate fs so that the flexible substrate fs is not detached downward by inserting the flexible substrate fs in the downward direction as shown in FIG.

During the separation, the flexible substrate fs may be configured to be moved in the lateral direction (lower right direction in FIG. 3) to be removed from the one-way clip 240

This one-way clip 240 may include a body 241, a support 242, an inclined portion 243, and a friction pad 244 as shown in FIG.

The main body 241 is formed on one side of the movable rail 220 and includes a fitting groove 241a through which the flexible substrate fs is fitted along the side surface in the lower portion of the main body 241, Can be formed.

The support member 242 is formed inside the main body 241 to support the flexible substrate fs and may be formed of a ball or a cylinder, and its function will be described below.

The inclined portion 243 is formed to be inclined in one side direction (downward direction in FIG. 4) in which the flexible substrate fs is inserted, thereby preventing the support 242 from being separated from the flexible substrate fs, It can serve to prevent separation.

The friction pad 244 is formed on the inner surface of the inclined portion 243 and can serve to provide a frictional force to allow the support 242 to more easily support the flexible substrate fs.

At this time, the elastic gripping part 321 may be configured to be able to rotate with the fixed guide bar 310 as well.

5, the pivot shaft 321a formed on both sides of the elastic gripping piece 321 is fitted and coupled to the pivoting groove 311a formed on both sides of the cutout portion 311 of the fixed guide bar 310 At the same time, it can be coupled to be pivotally moved by the locking bar 320 and the turning portion 321b.

6, when the operator turns the turning handle 330, the elastic supporting piece 321 is rotated as the locking bar 320 moves, and the lower portion of the flexible substrate fs is supported by using the elastic force can do.

At this time, a separate locking function may be added to the lower support rail 300 to maintain the state shown in the lower part of FIG. For example, after the rotation handle 330 is installed to penetrate the base frame 100, the rotation handle 330 may be coupled to the base frame 100 such that a part of the rotation handle 330 is maintained at a certain angle have. Of course, it is of course also possible to have the pivoting knob 330 fixed at the position shown in the lower part of Fig. 6 by various structures and methods according to the requirements of those skilled in the art.

Specifically, the fixed side support bar 400 is fixed to the side of the base frame 100 (the opposite side of the side where the movable rail protrudes from the upper left side in Fig. 7) to support the side surface of the flexible substrate fs .

In other words, when the flexible substrate fs supported by the movable rail 220 is inserted into the base frame 100, the side surface of the flexible substrate fs can be supported while being inserted into the fixing clip 410.

It goes without saying that the structure of the fixed side support bar 400 may be the same as or similar to the structure of the lower support rail 300 described above.

FIG. 8 is a view showing another embodiment of FIG. 1. FIG.

Referring to FIG. 8, the flexible substrate tray A of the present invention may further include a rotation side support bar 500.
