Definitions
- the invention applies to a printed circuit board built in or attached to an Ic card used as a bank card, accusation card or diagnostic card, especially for IC cards Processing and accumulating various types of information from lead writers, so-called
- Ic-card stell plate having an IC chip and external contact terminals for transmitting and receiving the above various information to and from the IC chip by electric signals. Is the thing.
- the format for sending and receiving information to and from the IC reader is as follows: a contact-type system that sends and receives electric signals via wires, and electromagnetic waves, magnets,
- the present invention is broadly divided into a non-contact type using a wireless signal such as light, and the present invention is particularly open to the former.
- This type of printed circuit board for Ic power which is internally or internally mounted on the IC card, is mounted on the IC chip and mounted on the IC card.
- Send information from writer It has an external connector required for reception, and a conductor circuit for electrically connecting the external contact terminal to an IC chip or the like.
- an IC module with an IC chip mounted on the IC card printing wiring ⁇ and a built-in or mounted IC module The following describes the Ic card itself. This kind of IC card requires the following conditions in consideration of its reliability and convenience in use.
- This kind of IC card is not appropriately small and thin as a whole so that it can be easily carried, managed, and inserted into the above-mentioned IC card lead / writer. must not.
- the thickness of the IC card in particular is about 0.78 earthquakes in order to match the size of the bank card and the like conventionally used. Since the thickness of the IC chip placed in the IC card is 0.25 or more at present, the thickness of the IC module excluding the external connection terminals must be 0.3 or more. Currently. (2) This type of Ic card must be electrically and frequently contacted with an IC card lead / writer by an external contact element exposed on its surface. In order to do so, the external connection terminal must be durable and have good electrical contact at all times.
- the conductor circuit for the IC chip built in or mounted on the IC card may be disconnected, or the IC module provided with the IC chip may be disconnected from the IC card. must not.
- this kind of IC card is basically * vinyl chloride It is composed of a sheet-like card material, which is a base material formed of plastic such as metal, and an IC module including an Ic chip and a printed wiring slope.
- a contact type IC card it is necessary to expose an external contact terminal for transmitting and receiving an electrical signal to the IC card surface as described above.
- progress has been made in a stepwise manner, but this historical extension has been made on March 13 and 14
- the training conducted by the Nissan Industrial Technology Center on a daily basis, ⁇ Development trends and new fields in multifunctional card systems, '' and Figs. 18 to 20 based on this are shown in FIG. Thus, they are roughly classified into three types.
- FIGS. 18 to 20 are longitudinal sectional views of the structure of the IC card joined by the respective joining methods, and the development stage of the IC card is shown in ⁇ of these figures. Has been.
- FIG. 18 is a partially enlarged cross-sectional view of an IC card in which a predetermined through-hole is formed in a sheet-like card material (31) and an IC module (12) is bonded in the through-hole.
- This shows a state in which the bonding between the IC module (12) and the sheet-like card material (31) is performed only on the side wall. Therefore, this 18
- the IC card shown in the figure may easily come off the sheet-like card material (31), and although the above condition (2) is sufficient, the condition (3) is not satisfied. Not only that, but the IC card has a thickness of 1 or less, resulting in poor bonding strength and a narrow practical range.
- FIG. 19 is a partial cross-sectional view of an IC card disclosed in, for example, JP-A-57-210494.
- the card is formed with a recess in the sheet-like card material (31), the IC module (12) is mounted in the recess, and the underside of the IC module (12) is overseaed. It is laminated according to (32).
- the IC module (12) has an external contact terminal (the conductor circuit (13) on the IC module (12) itself) corresponding to the external connection terminal formed on the upper surface of the IC module (12). It is fitted into the recess of the sheet-like card material (31) so as to be exposed on the card surface. That is, according to the above-mentioned Japanese Patent Application Laid-Open No.
- this IC card is provided with an IC module (12) in a recess formed by a blade in a sheet-like card material (31). It is disclosed to insert and bond.
- this type of IC card is bent so that the card is convex upward. In this case, the IC module (12) pops out, and there is still a drawback, and the condition (3) cannot be satisfied.
- FIG. 20 is a partial cross-sectional view of an IC card disclosed in Japanese Patent Application Laid-Open No. 56-26541, for example, and the IC card shown in FIG. Let's say “do a laminating type”.
- This laminated type IC card has oversheets (32) bonded to the upper and lower surfaces of the IC module (12) to expose the conductor circuit (13) that will be the external connection terminal part. An opening is formed in the upper oversheet (32).
- the IC card shown in FIG. 20 has an oversheet (32) in which only the portion corresponding to the external contact terminal is cut off. It is disclosed that it adheres onto the module (12).
- the condition of (3) can be satisfied to some extent. It is still not enough for the following reasons.
- the oversheet (32) is made of vinyl chloride (this material is generally used). Ah ), The thickness must be at least 0.1 'or more, and the thickness of this oversheet (32) must be 0.15 ⁇ or more if it can be found. It is.
