Abstract

PURPOSE:To reduce force applied to a semiconductor device and ensure that no cracks generate in a solder when an IC card itself is bent by adhering a sheet for preventing adhesion to an area corresponding to the semiconductor device on a panel through an adhesive. CONSTITUTION:A sheet for preventing adhesion 11 is adhered to an area corresponding to a specified IC 1 after providing an adhesive 9 on the adhesive surfaces of a front and a rear panel 7, 8. Consequently, when an IC card is loaded into or unloaded from an external device, the sheet 11 is caused to slide relative to the IC 1, if the IC card itself is bent, warping the front and rear panels 7, 8. This is because the IC 1 is not adhered to the sheet 11. Consequently, the force applied to a soldered part is minimized, if the IC card itself becomes bent, because the IC 1 is no longer pressed by the front and rear panels 7, 8.

However, in the conventional IC card configured in this way, when the IC card is inserted into or removed from the external device 10, for example, the rear part of the IC card may be pushed into the rC card by forceful operation. It was sometimes accidentally bent in a direction perpendicular to the main surface of the When the IC card is bent to the front side as shown in FIG. As it is distorted, the front panel 7 pushes the IC card toward the back side. Furthermore, since the ICI placed at the rear of the back side of the IC card is bonded to the back panel 8 with adhesive 9, it is pushed toward the front side of the IC card by the back panel 8. On the other hand, when the IC card is bent to the back side contrary to the above-mentioned case, the ICI placed at the rear of the front side of the IC card is pushed to the front side of the FC card, and the ICI
In the ICI located at the rear of the back side of the C card, the IC
Pushed to the back of the card. When the ICI is pressed in this way, stress is applied to the solder 4, which has the lowest strength, and this stress is applied to the ICI located at the part with the largest displacement, that is, at the rear of the IC card. The largest force will be applied to IC1 located at .

Therefore, when the IC card itself is repeatedly bent, cracks may appear in the solder 4 due to the above-mentioned stress, resulting in poor connection between the leads 2 and the lands 3a. In addition, in order to eliminate such a problem, when bonding both the front and back panels 7 and 8 to the frame 5, in order to prevent the ICI from being glued to both the front and back panels 7 and 8, it is necessary to However, if you are handling IC cards with different IC 1 attachment positions at the same time, removing the adhesive 9 is very troublesome and takes too much time. This ends up increasing costs.

In the figure and FIG. 2, 1l is the ICI on the front panel 7.
This sheet 11 is an anti-adhesion sheet for preventing adhesion to the back panel 8, and this sheet 11 is adhered to the portions of both the front and back panels 7 and 8 that correspond to the ICI located at the rear of the IC card. . Further, this sheet 11 is bonded to both the front and back panels 7, 8 using an adhesive 9 for bonding both the front and back panels 7, 8 to the frame 5, and when installing this sheet 11, both the front and back panels must be After applying adhesive 9 to the adhesive surfaces of each of the panels 7 and 8, a sheet 11 is adhered to a portion corresponding to a predetermined portion 1C1.

In the IC card according to the present invention configured as described above, when inserting or removing it from an external device,
As shown in FIG. 2, when both the front and back panels 7 and 8 are distorted due to bending of the IC card itself, the ICI and the adhesive prevention sheet 11 are not bonded and fixed. This sheet 11 is slid and shifted relative to the ICI. Therefore, even if the IC card itself is bent, the ICI will not be pushed by both the front and back panels 7.8, so the force applied to the soldering portion can be kept low.

In this embodiment, an example was shown in which the adhesion prevention sheet l1 was provided at a portion corresponding to the IC placed at the rear of the IC card (a portion with relatively large displacement), but the present invention is applicable to such an arrangement. The present invention is not limited to this, and they may be provided in portions corresponding to each IC. In this way, it is possible to reliably prevent stress from being applied to the soldered portion even if it is bent at a time other than when it is inserted into or removed from an external device.

As explained above, according to the present invention, since the adhesion prevention sheet is adhered to the portion of the panel corresponding to the semiconductor device through the adhesive, when the IC card itself is bent, the adhesion prevention sheet is attached to the semiconductor device. It will be slid against the device. Therefore, the force applied to the semiconductor device is reduced, and cracks in the solder can be reliably prevented, making it possible to obtain a high-quality IC card.
