Description

  The present invention relates to a flexible printed wiring board storage tray suitable for storing and transporting flexible printed wiring boards.

  Flexible printed wiring boards with flexibility are frequently used in the field of electronic devices and the like. The flexible printed wiring board includes, for example, a conductive layer made of copper foil or the like laminated on an electrically insulating resin film or the like. A predetermined wiring pattern is formed from the conductive layer using a subtractive method or an additive method.

  The flexible printed wiring board is highly flexible. For this reason, while being formed with hard resin etc., it is stored or conveyed in the state stored in the storage tray which provided the storage space of the shape and dimension corresponding to the flexible printed wiring board.

JP 2002-193341 A

  As a method of removing the flexible printed wiring board from the storage tray, a method of picking up the edge of the flexible printed wiring board and pulling it upside down or dropping the printed wiring board downward from the storage tray is adopted. Often done.

  However, when the flexible printed wiring board is picked up and pulled, the space between the lower surface of the flexible printed wiring board and the inner surface of the storage tray is in a reduced pressure state, and the flexible printed wiring board is pulled to the tray side. For this reason, force acts on a flexible printed wiring board, and damage, such as curvature and a wrinkle, tends to arise.

  Similarly, in the method in which the storage tray is turned over and the flexible printed wiring board is taken out of the storage tray, the reduced pressure state occurs between the inner surface of the tray and the flexible printed wiring board. For this reason, a force acts on the flexible printed wiring board and warpage and wrinkles are likely to occur. Further, since the flexible printed wiring board cannot be dropped smoothly, there is a problem that workability is lowered.

  In addition, when a high accuracy is required, such as a flexible printed wiring board used for a flexure for a hard disk device, a storage tray with a lid that seals the internal space and does not allow dust to enter may be used. Even when such a storage tray is employed, when the lid is opened, the pressure is reduced between the inner surface of the lid and the upper surface of the flexible printed wiring board facing the lid. For this reason, force is often applied to the flexible printed wiring board to cause damage such as warpage and wrinkles.

  Furthermore, there are cases where a plurality of trays are stacked and used. However, when removing the tray from which the flexible printed wiring board is taken out and taking out the flexible printed wiring board from the tray stacked below, The space between the flexible printed wiring board housed in the lower tray is in a reduced pressure state, and problems similar to those with the lid tray are likely to occur.

  In order to avoid the above inconvenience, a tray body or a lid body having a vent hole is provided. However, when the vent hole is provided, the storage space cannot be sealed at the time of transportation, and thus there is a problem that dust is likely to enter the storage space. In addition, depending on the form of the air hole, there is a problem that the peripheral edge of the air hole is pressed against the flexible printed wiring board and transferred to the flexible printed wiring board, thereby damaging the flexible printed wiring board. Furthermore, there is a possibility that the flash generated when forming the vent hole and dust generated due to the flash may damage the flexible printed wiring board. For this reason, it cannot be applied to a flexible printed wiring board requiring accuracy.

  The present invention has been devised to solve the above-described problems, and it is an object to provide a storage tray for a flexible printed wiring board that can be taken out without damaging the flexible printed wiring board. To do.

  The invention described in claim 1 of the present application is a storage tray for a flexible printed wiring board, comprising: a main body having a storage space; and a lid capable of sealing the storage space so as to cover an upper opening of the main body. One or both of the main body and the lid are provided with vent hole forming means capable of forming a vent hole communicating with the storage space when the flexible printed wiring board is taken out.

  The storage tray according to the present invention includes a main body and a lid that can form a sealed storage space. For this reason, there is no possibility that dust or the like enters the storage space during the conveyance of the flexible printed wiring board. Therefore, the present invention can also be applied to a flexible printed wiring board that requires accuracy.

  In the present invention, a vent hole forming means capable of forming a vent hole communicating with the storage space when taking out the flexible printed wiring board is provided in one or both of the main body and the lid.

  During the conveyance, the vent hole forming means is not formed with a vent hole, or is held in a state where the vent hole is sealed and does not communicate with the storage space. On the other hand, when the flexible printed wiring board is taken out from the storage tray, a vent hole communicating with the storage space is formed, or a pre-formed vent hole is configured to communicate with the storage space.

  For example, as in the invention described in claim 4, the vent hole forming means is sealed so as to cover the vent hole provided in the main body and / or the lid body, and can be peeled off. And a sheet-like sealing member adhered to the substrate.

  By adhering the sheet-like sealing member to an adhesive layer applied around the vent hole, the vent hole can be sealed. On the other hand, by peeling the sheet-like sealing member, the sealing can be released and the storage space can be communicated with the outside. For this reason, during transportation, etc., it is possible to seal the storage space and prevent dust from entering, and when taking out the flexible printed wiring board, external air is caused to flow into the storage space to cause a decompression phenomenon. It can be prevented from occurring.

  In addition, as in the invention described in claim 5, the vent hole forming means is integrally formed with the main body and / or the lid body, and the vent hole communicates with the storage space by being broken or broken. It can comprise and comprise the projection part in which is formed.

  For example, a rod-like protrusion in which a vent hole penetrating the lid body is formed by breaking the lid body at a predetermined position can be provided. By providing a weakened portion having a thickness smaller than that of the other part of the lid around the rod-shaped projection, the rod-shaped projection can be easily broken to form the vent hole.

  In addition, a knob that can be pulled or pushed is integrally formed at a predetermined position of the lid, and a weakened portion having a thickness smaller than that of the other part of the lid is provided around the knob, and the knob is pulled or pushed. A part of the lid can be broken to form the vent hole communicating with the storage space.

  By adopting the above-described configuration, it is possible to prevent the dust from entering since the storage space is sealed during conveyance. On the other hand, when taking out the flexible printed circuit board, a vent hole for introducing outside air can be formed. For this reason, when taking out from a storage tray, it becomes possible to prevent a decompression phenomenon and there is no possibility that a flexible printed wiring board will be damaged.

  The vent hole forming means can be provided on one of the main body and the lid body, or can be provided on both, depending on the form of the flexible printed wiring board and the storage tray. In order to prevent the flexible printed wiring board from being damaged, it is preferable to provide it on both sides.

  For example, when the vent hole forming means is provided in both the main body and the lid, the flexible printed wiring board can be taken out from the tray as follows.

  First, before the lid body is detached from the main body, a vent hole is formed on the lid body side using vent hole forming means provided in the lid body. Thereafter, the lid is removed from the main body. Since the vent hole is formed, the gap between the inner surface of the lid and the upper surface of the flexible printed wiring board is not decompressed. For this reason, when removing a cover, a flexible printed wiring board does not roll up. Therefore, there is no possibility of warping or wrinkling and damaging the flexible printed wiring board.

  Next, vent holes are formed in the bottom of the main body using vent hole forming means provided in the main body. Thereafter, the flexible printed wiring board is taken out from the storage space. Since the vent hole is formed, the space between the bottom surface of the main body and the lower surface of the flexible printed wiring board is not reduced, and the flexible printed wiring board can be easily taken out.

  The position where the vent hole forming means is provided is not particularly limited, but it is preferably formed in the central portion of the main body and / or the lid as in the invention described in claim 2.

  When the lid is removed, the peripheral edge is often first separated from the main body. For this reason, outside air is introduced from the separated portion, while the central portion of the storage space or the side opposite to the separated side is decompressed.

  Similarly, when the flexible printed wiring board is taken out from the storage space, the edge portion is often first detached from the tray. In this case as well, it is considered that the central portion or the side opposite to the separated side is decompressed as in the case of the lid. Therefore, by providing the vent hole forming means in the central portion, it is possible to effectively suppress the depressurization phenomenon between the main body or the lid and the flexible printed wiring board.

  The form and the number of the vent hole forming means are not limited as long as outside air can be introduced to prevent the above-described decompression phenomenon. The amount of outside air that needs to be introduced to prevent the decompression phenomenon increases as the size of the flexible printed wiring board increases. Therefore, the size and number of vent holes can be set according to the dimensions of the tray and the flexible printed wiring board. For example, as in the invention described in claim 3, a plurality of the vent hole forming means can be provided in the main body and / or the lid body, respectively.

  The main body and the lid can be separately formed in different shapes, and the main body is formed on the other main body containing the flexible printed wiring board so that the lid can be configured. You can also In this case, it is preferable that the vent hole forming means is provided apart from the flexible printed wiring board so as not to damage the flexible printed wiring board.

  By configuring the main body so that it can also be used as the lid, the flexible printed wiring board storage tray according to the present invention can be configured only by the main body of the tray. Therefore, the cost can be reduced.

  Moreover, since two or more storage spaces can be configured by stacking three or more main bodies, it is possible to reduce the conveyance space and the like. In this case, it is desirable that the vent hole forming means is configured so that the vent hole can be opened from both inside and outside the tray.

  According to the present invention, the flexible printed wiring board can be easily taken out from the storage tray without being damaged.

  Embodiments according to the present invention will be specifically described below with reference to the drawings.

The pressure-sensitive adhesive layers 12a and 12b provided so as to surround the region and the sheet-like sealing members 13a and 13b laminated on the pressure-sensitive adhesive layers 12a and 12b.

  The sheet-like sealing members 13a and 13b are bonded to the pressure-sensitive adhesive layers 12a and 12b at the edges, thereby sealing the vent holes 11a and 11b and holding the storage space 5 in a sealed state. It is configured to be able to. Moreover, the said sheet-like sealing members 13a and 13b are formed smoothly so that the sticking surface to an adhesive has releasability, and can be easily peeled from the said adhesive layers 12a and 12b. . The material which comprises the said sheet-like sealing members 13a and 13b is not specifically limited, It can form using a resin sheet, paper, etc. Moreover, in order to perform peeling easily, the knob | pick parts 14a and 14b extended from an edge part are provided.

  Vent holes 11a and 11b are formed in the lid 3 and the main body, but the vent holes 11a and 11b are sealed in a state where the sheet-like sealing members 13a and 13b are adhered. The storage space 5 is kept sealed. For this reason, dust does not enter the storage space 5 through the vent holes 11a and 11b in the middle of conveyance or the like, and the flexible printed wiring board 4 is not damaged.

  A procedure for taking out the flexible printed wiring board 4 from the tray 1 according to the present embodiment will be described with reference to FIGS. 3 to 5.

  First, as shown in FIG. 3, the sheet-like sealing member 13a on the lid 3 side is peeled off from the pressure-sensitive adhesive layer 12a, and between the inner surface of the lid and the upper surface of the flexible printed wiring board via the vent hole 11a. The space 5a is communicated with the outside air. In this state, the lid 3 is lifted away from the main body, and at the same time, outside air flows into the space 5a from the vent hole 11a. For this reason, the lid 3 can be removed without depressurizing the space a. Therefore, the flexible printed wiring board 4 is not rolled up together with the lid 3, and unnecessary force acts on the flexible printed wiring board 4, so that there is no possibility of warping, wrinkling, or the like.

  Next, the sheet-like sealing member 13b is peeled off from the vent hole forming means 10b provided on the main body 2 side. Thereby, the space 5b between the bottom surface of the main body 2 and the lower surface of the flexible printed wiring board 4 is communicated with the outside air through the vent hole 11b. When the flexible printed wiring board 4 is lifted from the storage space 5 in this state, outside air is introduced into the space 5b from the vent hole 11b in the same manner as described for the lid 3. Therefore, the space 5b is not decompressed, and the flexible printed wiring board 4 can be easily taken out from the storage space 5. Further, since the force due to the reduced pressure does not act on the flexible printed wiring board 4, there is no possibility that the flexible printed wiring board 4 is warped or wrinkled.
