Abstract

PURPOSE:To obtain an IC card of high quality which enables an ease of operation to be improved. CONSTITUTION:An IC card consists of an IC chip 6 incorporated and an IC module 2 with an external contact terminal 4 adhered to a card substrate 3 of card shape, and the IC module 2 is adhered to the card substrate using more than two different types of adhesive 10,11. It is possible to use adhesives of different forms having different curing times and curing processes by adhering the IC module 2 to the card substrate 3 with a combination of more than two different types of adhesive. Thus the IC module 2 is positioned during a process, a curing process is simplified and an ease of operation is increased. Further, an adequate hardness after the curing process is obtained and also an adhesive power suited for, e.g. the peripheral, cater and thick/thin parts of the IC module 2 is obtained by using adhesives having different levels of adhesive power. Subsequently, the stabilization of strength and quality is ensured.

According to this method, when the IC module 2 is inserted into the concave portion 3a, it is immediately fixed and positioned, and only the outer peripheral portion is ultrasonically pressure-bonded, so that the IC chip 6 is not stressed, and the outer peripheral portion is not covered with the adhesive. There is a merit that strong adhesion can be obtained. Further, even if the adhesive on the outer peripheral portion is a liquid adhesive that takes a long time to cure, there is an advantage that fixing is not necessary during curing. FIG. 4 shows another method I
It is sectional drawing of the IC card 1 which fixed the C module 2. In the step, first, the IC module 2 is made in advance.
Then, the instant adhesive 1 is applied to the center of the concave portion 3a of the card base material 3.
Apply 5. The IC module 2 is inserted into the recess 3a and fixed. After that, liquid elastic adhesive 16 is applied to the outer peripheral portion.

Further, structurally, the corner chamfered portion 2a is formed on the outer peripheral portion of the IC module 2, and the R portion 3b is formed on the outer periphery of the concave portion 3a of the card base material 3, so that the IC card 1 is bent. In this case, stress concentration and damage around the outer peripheral portion of the IC module 2 are prevented.

According to such a bonding method, a strong adhesive force is obtained by the elastic adhesive 16 on the outer peripheral portion of the IC module 2, and the IC module 2 is immediately fixed by the instant adhesive 15. It is not necessary to fix and hold the IC module 2 with a jig or the like while the adhesive 16 is cured by heating.

As described above, the IC card 1 of the present invention applies the liquid adhesive to the entire bottom surface of the module as in the conventional case,
It is not necessary to hold the adhesive until it is cured by a jig or the like, and workability can be improved. Further, unlike the conventional case where the entire module is bonded by ultrasonic pressure bonding with a sheet adhesive, the IC chip is not damaged.

Besides, the present invention is not limited to the above embodiment.
For example, in the example of FIG. 1, the sheet-shaped pressure-sensitive adhesive 10 is used, but even if the liquid adhesive is used, there is an advantage that the ultrasonic bonding is applied only to the outer circumference to prevent stress on the IC chip 2. .. Further, an ultraviolet curable adhesive may be used on the outer peripheral portion of the module and another adhesive may be used on the central portion. Two or more kinds of adhesives having different hardness after curing may be used. Of course, various modifications can be made without departing from the spirit of the invention.
