いる。When the laminate of strip-shaped lead frames is stored in a plastic bag and transported as described above, the strip-shaped lead frames can be protected from dirt and dust during transportation. However, since the plastic bag has a poor impact resistance function and a poor binding function of integrating each strip-shaped lead frame, the strip-shaped lead frame may be rubbed sideways due to an impact during transportation, and the strip-shaped lead frame may be damaged. There is a disadvantage that the frame is easily damaged. On the other hand, when storing the laminated body of strip-shaped lead frames in a dedicated hard case for transportation, the dedicated hard case has sufficient impact resistance, but the thermal expansion and In consideration of heat shrinkage and the like, the size of the dedicated hard case is set to have a margin with respect to the size of the laminate of the strip-shaped lead frames.

The lead frame may be damaged. Furthermore, when the dedicated hard case is used for transportation, a dedicated hard case is required for each type of lead frame to be transported, and the management is extremely complicated and the transportation cost is increased. Therefore, an object of the present invention is to
An object of the present invention is to provide a lead frame fixing plate and a package that can prevent lateral rubbing during transportation by integrating a laminated body in which strip-shaped lead frames are laminated, and that can be easily managed.

The stoppers formed on the fixing members abut against one of the two end surfaces along the short axis of the laminated body to position each fixed plate. Then, the strip-shaped lead frames of the laminated body can be integrated by integrating the fixing plates by an integrating means such as tape winding. For this reason, it is possible to prevent the strip-shaped lead frame from being laterally rubbed during transportation, thereby preventing the strip-shaped lead frame from being damaged. On the other hand, a stopper is not formed at the other end of the concave groove of each fixing plate, so that expansion and contraction of the strip-shaped lead frame due to temperature change during transportation can be allowed, and The deformation of the lead frame can be prevented. Furthermore, since the stopper portion is formed only at one end of the concave groove of each fixing plate, the length of the fixing plate does not have to be the same as the length of the laminated body, and a dedicated case must be provided for each type of lead frame to be manufactured. It is not necessary, and the management of the transportation member can be easily performed.

動機で行っても手動で行ってもよい。The packaging of the rectangular laminate 16 in which the strip lead frames 10 are laminated using such a pair of fixing plates 14a and 14b can be performed according to the procedure shown in FIG. First, a rectangular laminated body 16 is formed by laminating a predetermined number of strip-shaped lead frames 10 on the mounting table 30 (FIG. 2A). Next, the fixing plates 14a and 14b are
Side surfaces 22 along the long axis of the laminated body 16 formed on the mounting table 30 are formed in the concave grooves 20a, 20b of the fixing plates 14a, 14b.
a and 22b are slid in opposite directions while being mounted. At this time, the fixing plates 14a, 14b are mounted so that the stopper portions 18a, 18b formed at one ends of the concave grooves 20a, 20b abut against the end surfaces 24, 25 along the short axis of the laminated body 16, respectively. 2 (b)]. Note that the thickness of the laminated body 16 is not more than that of the concave grooves 20a, 2b of the fixed plates 14a, 14b.
If the groove width is smaller than 0b, a spacer may be further laminated on the laminate 16. The fixed plates 14a, 1
4b is the end face 2 of the laminate 16
After contacting each of the stacks 4 and 25, the stack 16 is placed on the mounting table 30.
Then, the fixing plates 14a and 14b are integrated. In the present embodiment, the fixing plates 14a and 14b are integrated by winding the tapes 32 and 32 at two places [FIG. 2 (c)]. The winding of the tapes 32, 32 may be performed by an automatic machine or manually.

In order to prevent dirt, dust and the like during transportation, they may be transported in a plastic bag or the like. Fixed plates 14a, 14b of the present embodiment
According to this, the laminated body 16 has the fixing plate 14a on both side surfaces thereof,
Since the strip-shaped lead frames 10 that are in close contact with the bottom surfaces of the concave grooves 20a and 20b of the 14b and that form the laminate 16 are integrated, it is possible to prevent the strip-shaped lead frames 10 from being laterally rubbed during transportation. . Also, the fixing plates 14a, 14
Since the stopper portions 18a and 18b are formed only at one end of the concave grooves 20a and 20b, the thermal expansion and contraction of the strip-shaped lead frame 10 due to a temperature change during transportation are allowed, and the temperature change and the like are allowed. Therefore, the deformation of the strip-shaped lead frame 10 due to this can be prevented. Further, at the destination where the strip-shaped lead frame 10 is used, the integration of the strip-shaped lead frames 10 forming the laminate 16 by the fixing plates 14a and 14b can be easily released, and automation can be easily performed.

b does not need to be covered, for example, as shown in FIG.
A part of the side surface of the laminate 16 may be exposed. Therefore, it is not necessary to prepare for each type of the strip-shaped lead frame 10 for transporting the fixing plates 14a and 14b, and it is sufficient to prepare several types of fixing plates 14a and 14b according to the thickness and length of the laminated body. is there. Therefore, it is possible to easily manage the transportation members and the like, and it is possible to reduce the transportation cost of the strip-shaped lead frame. The fixing plates 14a, 1
