Description

【０００１】
【発明の属する技術分野】
本発明は、例えば、定期券や証明カード等として適用される無線カードに関する。
【０００２】
【従来の技術】
この種の無線カードとしては、例えば、図１０に示すようなものが知られている。
即ち、図中１０１はカード基板で、このカード基板１０１上には電子部品としてのＬＳＩ１０２及びアンテナパタン（図示せず）等が配設されている。
【０００３】
カード基板１０１とＬＳＩ１０２等は、表面シート１０６と裏面シート１０７とにより被覆されている。表面シート１０６と裏面シート１０７との間には充填材１０９が充填されている。
【０００４】
ところで、ＬＳＩ１０２の実装部の強度を増すために、ＬＳＩ１０２の下面側にはカード基板１０１を介して第１の補強体としての第１の補強ＳＵＳ箔１０３が設けられ、ＬＳＩ１０２の上面側には直接第２の補強体としての第２の補強ＳＵＳ箔１０４が設けられている。第１及び第２の補強ＳＵＳ箔１０３，１０４は、ＬＳＩ１０２とほぼ同サイズで厚さ２０μｍとなっている。
【０００５】
【発明が解決しようとする課題】
しかしながら、従来においては、ＬＳＩ１０２の実装部に第１及び第２の補強ＳＵＳ箔１０３，１０４を接着することで強度は増したが、この補強された部分と、ＬＳ１１０２の実装部外周の補強がなされていない部分との間の強度差が大き過ぎたため、図１１に示すように、カードが曲げられたときにＬＳ１実装部の外周に曲げ応力が集中し、カードの表面シート１０６が破れてしまうという問題があった。
【０００６】
本発明は、上記事情に着目してなされたもので、その目的とするところは、カードが曲げられた場合には、電子部品の実装部外周部に発生する曲げ応力を分散させて被覆材の破損を防止できるようにした無線カードを提供することを目的とする。
【０００７】
【課題を解決するための手段】
上記した課題を解決するため、請求項１記載のものは、無線用の電子部品及びアンテナを配設する基体と、この基体、さらに前記電子部品及びアンテナを被覆する被覆材と、前記電子部品の一面側に前記基体を介して設けられる第１の補強体と、前記電子部品の他面側に設けられる第２の補強体とを具備し、前記第１の補強体は前記電子部材よりも外形寸法を大とし、その外周部を前記電子部品の外周部から外方に突出させる。
【０００８】
請求項３記載のものは、無線用の電子部品及びアンテナを配設する基体と、この基体、さらに前記電子部品及びアンテナを被覆する被覆材と、前記電子部品の一面側に前記基体を介して設けられる第１の補強体と、前記電子部品の他面側に設けられる第２の補強体と、この第２の補強体と前記被覆材との間に設けられ、外形寸法を前記電子部材よりも大とし、その外周部を前記電子部品の外周部から外方に突出させる第３の補強体とを具備する。
【０００９】
請求項４記載のものは、無線用の電子部品及びアンテナを配設する基体と、この基体、さらに前記電子部品及びアンテナを被覆する被覆材と、前記電子部品の一面側の両側部に前記基体を介してそれぞれ設けられる一対の第１の補強体と、前記電子部品の他面側に設けられる第２の補強体とを具備し、前記一対の第１の補強体はその一部を前記電子部材の両側部から外方へ突出させる。
【００１０】
請求項６記載のものは、無線用の電子部品及びアンテナを配設する基体と、この基体、さらに前記電子部品及びアンテナを被覆する被覆材と、前記電子部品の一面側に前記基体を介して設けられる第１の補強体と、前記電子部品の他面側に設けられる第２の補強体と、前記電子部品の周囲部に設けられたクッション材とを具備する。
【００１１】
【発明の実施の形態】
以下、本発明を図面に示す実施の形態を参照して詳細に説明する。
図１は、本発明の一実施の形態である無線カード１を示す平面図で、図２は図１中のＡ−Ａ線に沿って示す断面図である。
【００１２】
無線カード１は基体としての基板２を有し、この基板２の材料としては、例えば、厚さ０．０５ｍｍのポリエチレンテレフタレート（以下、ＰＥＴという）が用いられる。この基板２の上面部には電子部品としてのＬＳＩ３が実装されているとともに、アンテナパタン４が設けられている。アンテナパタン４は例えば、厚さ０．０１２ｍｍのアルミ箔をエッチングして形成される。
【００１３】
アンテナパタン４の両端子４ａ，４ｂはＬＳＩ３のバンプ５ａ，５ｂにフリップチップ方式で接続される。ＬＳＩ３はＡＣＦ６を介して基板２に電気的に接続されている。
【００１４】
ＬＳＩ３の下面側には、基板２を介してＬＳＩ３よりも大きな外形寸法を有する厚さ１００μｍの第１の補強体としての第１の補強ＳＵＳ箔７が接着されている。この第１の補強ＳＵＳ箔７の外形寸法は、ＬＳ１３の寸法にカード１の厚さ寸法の４倍の寸法を加えたものであり、その外周部はＬＳＩ３の外周部から外方に突出されている。
【００１５】
ＬＳＩ３の上面側にはＬＳＩ３とほぼ同サイズで厚さ２０μｍの第２の補強体としての第２の補強ＳＵＳ箔８が接着により一体化されている。
基板２、ＬＩＳ３及びアンテナパタン４は被覆材としての表面シート１０と裏面シート１１とにより被覆されている。表面シート１０と裏面シート１１との間には充填材１２が充填されている。
【００１６】
このように構成される無線カード１は、カード外部から供給される電波を電力に変換してＬＳＩ３を動作させ、残りの電力でレスポンスを返して非接触でデータ通信を可能とする。
ところで、無線カード１はその使用時等に誤って例えば図３に示すように曲げられてしまうことがある。このとき、無線カード１には曲げ応力が発生するが、第１の補強ＳＵＳ箔７がＬＳＩ３よりも大きな外形寸法を有し、その外周部７ａをＬＳＩ３の外周部から外方に突出させているため、この外周部７ａが無線カード１の曲がりの抵抗として機能する。
【００１７】
従って、ＬＳＩ３の上面側の角部で無線カード１が急激に湾曲することがなく、曲げ応力が分散され、表面シート１０に対し損傷（クラック）を与えることがない。
【００１８】
図４及び図５は、本発明の第２の実施の形態である無線カード１５を示すものである。
なお、上記した第１の実施の形態で示した部分と同一部分については同一番号を付して省略する。
【００１９】
この実施の形態では、ＬＳＩ３の第２の補強ＳＵＳ箔８と表面シート１０との間に第３の補強体としての第３の補強ＳＵＳ箔１６が設けられている。第３の補強ＳＵＳ箔１６は、厚さが２０μｍで、ＬＳ１３の外形寸法よりも大きな外形寸法を有し、その外周部１６ａはＬＳＩ３の外周部から外方に突出されている。
【００２０】
このように構成される無線カード１５が例えば、図５に示すように曲げられると、無線カード１５には曲げ応力が発生するが、ＬＳＩ３と表面シート１０との間には第３の補強ＳＵＳ箔１６が介在され、その外周部１６ａがＬＳＩ３の外周部から外方に突出されてるため、外周部１６ａが無線カード１５の曲がりの抵抗として機能する。
【００２１】
従って、ＬＳＩ３の上面側の角部で無線カード１５が急激に湾曲することがなく、曲げ応力が分散され、表面シート１０に対し損傷（クラック）を与えることがない。
【００２２】
図６及び図７は、本発明の第３の実施の形態である無線カード２０を示すものである。
なお、上記した第１の実施の形態で示した部分と同一部分については同一番号を付して省略する。
【００２３】
この実施の形態では、ＬＳＩ３の下面側に設けられる第１の補強体が一対の補強ＳＵＳ箔２１，２２によって構成されている。
一対の補強ＳＵＳ箔２１，２２は、厚さが２０μｍで、その一部２１ａ，２２ａをＬＳＩ３の角部から外方に突出させ、その突出寸法は、カード厚さの２倍の寸法となっている。
【００２４】
このように構成される無線カード２０が例えば、図７に示すように曲げられると、無線カード２０には曲げ応力が発生するが、一対の補強ＳＵＳ箔２１，２２がその一部２１ａ，２２をＬＳＩ３の角部から外方に突出させるため、この突出部２１ａ，２２ａが無線カード１の曲がりの抵抗として機能する。
【００２５】
従って、無線カード２０がＬＳＩ３の上面側の角部で急激に湾曲することがなく、曲げ応力が分散され、表面シート１０に対し損傷（クラック）を与えることがない。
【００２６】
図８及び図９は、本発明の第４の実施の形態である無線カード２５を示すものである。
なお、上記した第１の実施の形態で示した部分と同一部分については同一番号を付して省略する。
【００２７】
この実施の形態では、ＬＳＩ３の外周部にクッション材２６を設けている。
このように構成される無線カード２５が例えば、図９に示すように曲げられると、無線カード２５には曲げ応力が発生するが、ＬＳＩ３の外周部にはクッション材２６が設けられているため、無線カード２０がＬＳＩ３の上面側の角部で急激に湾曲することがなく、応力集中が緩和され、表面シート１０に対し損傷（クラック）を与えることがない。
【００２８】
その他、本発明はその要旨の範囲内で種々変形実施可能なことは勿論である。
【００２９】
【発明の効果】
以上説明したように、本発明によれば、カードが曲げられても電子部品実装部の外周部への応力集中を避けることができ、被覆部材の破損を防止することができるという効果を奏する。

BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
FIG. 1 is a plan view showing a wireless card 1 according to an embodiment of the present invention, and FIG. 2 is a sectional view taken along line AA in FIG.
[0012]
The wireless card 1 has a substrate 2 as a base. As a material of the substrate 2, for example, polyethylene terephthalate (hereinafter, referred to as PET) having a thickness of 0.05 mm is used. On the upper surface of the substrate 2, an LSI 3 as an electronic component is mounted, and an antenna pattern 4 is provided. The antenna pattern 4 is formed, for example, by etching an aluminum foil having a thickness of 0.012 mm.
[0013]
Both terminals 4a and 4b of the antenna pattern 4 are connected to the bumps 5a and 5b of the LSI 3 in a flip-chip manner. The LSI 3 is electrically connected to the substrate 2 via the ACF 6.
[0014]
A first reinforcing SUS foil 7 as a first reinforcing body having a thickness of 100 μm and having a larger outer dimension than the LSI 3 is bonded to the lower surface side of the LSI 3 via the substrate 2. The outer dimensions of the first reinforced SUS foil 7 are the dimensions of the LS 13 plus four times the thickness of the card 1, and the outer periphery of the first reinforcement SUS foil 7 projects outward from the outer periphery of the LSI 3. I have.
[0015]
On the upper surface side of the LSI 3, a second reinforcing SUS foil 8 as a second reinforcing body having the same size as the LSI 3 and a thickness of 20 μm is integrated by bonding.
The substrate 2, the LIS 3, and the antenna pattern 4 are covered with a top sheet 10 and a back sheet 11 as covering materials. A filler 12 is filled between the top sheet 10 and the back sheet 11.
[0016]
The wireless card 1 configured as described above operates a LSI 3 by converting radio waves supplied from outside the card into electric power, returns a response with the remaining electric power, and enables non-contact data communication.
By the way, the wireless card 1 may be erroneously bent when used, for example, as shown in FIG. At this time, bending stress is generated in the wireless card 1, but the first reinforcing SUS foil 7 has an outer dimension larger than that of the LSI 3, and its outer peripheral portion 7a projects outward from the outer peripheral portion of the LSI 3. Therefore, the outer peripheral portion 7a functions as a bending resistance of the wireless card 1.
[0017]
Therefore, the wireless card 1 does not bend sharply at the corner on the upper surface side of the LSI 3, the bending stress is dispersed, and the topsheet 10 is not damaged (cracked).
[0018]
FIGS. 4 and 5 show a wireless card 15 according to a second embodiment of the present invention.
Note that the same parts as those described in the first embodiment are denoted by the same reference numerals and will not be described.
[0019]
In this embodiment, a third reinforced SUS foil 16 as a third reinforced body is provided between the second reinforced SUS foil 8 of the LSI 3 and the topsheet 10. The third reinforcing SUS foil 16 has a thickness of 20 μm and an outer dimension larger than the outer dimension of the LS 13, and its outer peripheral portion 16 a protrudes outward from the outer peripheral portion of the LSI 3.
[0020]
When the wireless card 15 configured as described above is bent, for example, as shown in FIG. 5, a bending stress is generated in the wireless card 15, but a third reinforcing SUS foil is provided between the LSI 3 and the topsheet 10. Since the outer peripheral portion 16a is protruded outward from the outer peripheral portion of the LSI 3, the outer peripheral portion 16a functions as a bending resistance of the wireless card 15.
[0021]
Therefore, the wireless card 15 does not bend sharply at the corner on the upper surface side of the LSI 3, the bending stress is dispersed, and the topsheet 10 is not damaged (cracked).
[0022]
6 and 7 show a wireless card 20 according to a third embodiment of the present invention.
Note that the same parts as those described in the first embodiment are denoted by the same reference numerals and will not be described.
[0023]
In this embodiment, a first reinforcing member provided on the lower surface side of the LSI 3 is constituted by a pair of reinforcing SUS foils 21 and 22.
The pair of reinforced SUS foils 21 and 22 have a thickness of 20 μm, and their portions 21a and 22a are projected outward from the corners of the LSI 3, and the projected dimension is twice as large as the card thickness. I have.
[0024]
When the wireless card 20 thus configured is bent, for example, as shown in FIG. 7, bending stress occurs in the wireless card 20, but the pair of reinforcing SUS foils 21 and 22 form portions 21 a and 22 thereof. The protrusions 21a and 22a function as bending resistance of the wireless card 1 so as to protrude outward from the corners of the LSI 3.
[0025]
Therefore, the wireless card 20 does not bend sharply at the corner on the upper surface side of the LSI 3, the bending stress is dispersed, and the topsheet 10 is not damaged (cracked).
[0026]
8 and 9 show a wireless card 25 according to a fourth embodiment of the present invention.
Note that the same parts as those described in the first embodiment are denoted by the same reference numerals and will not be described.
[0027]
In this embodiment, a cushion material 26 is provided on the outer peripheral portion of the LSI 3.
When the wireless card 25 configured as described above is bent, for example, as shown in FIG. 9, bending stress occurs in the wireless card 25, but since the cushion material 26 is provided on the outer peripheral portion of the LSI 3, The wireless card 20 does not bend sharply at the corner on the upper surface side of the LSI 3, stress concentration is eased, and the topsheet 10 is not damaged (cracked).
[0028]
In addition, it is a matter of course that the present invention can be variously modified within the scope of the gist.
[0029]
【The invention's effect】
As described above, according to the present invention, even when the card is bent, stress concentration on the outer peripheral portion of the electronic component mounting portion can be avoided, and the effect of preventing damage to the covering member can be obtained.
