Description

【0001】
【発明の属する技術分野】
本発明は、配線パターンが形成され、不要輻射を抑制することができるフレキシブル配線基板および撮像装置に関する。
【0002】
【従来の技術】
フレキシブル配線基板(以下、FPCという)には、両面に配線パターンが形成された両面FPCと片面に配線パターンが形成された片面FPCがあり、このFPCは、その薄さや屈曲性の良さ等からデジタルカメラやコンピュータ機器等の様々な機器で使用されている。
【0003】
中でも比較的規模の大きい回路を形成する場合には両面FPCが用いられることが多いが、この両面FPCは、非導電性材料の両面に導体を貼付しているため、製造が面倒である上に値段も高価であり、しかも、多くの屈曲を繰り返すうちに破断等が生じやすくて耐屈曲性に弱いという欠点がある。
【0004】
このため、両面FPCに比べて比較的製造が容易で値段も安く、屈曲を繰り返し行うような電子回路を搭載する場合には、片面FPCを使用することが多い。
【0005】
ところで、FPCは、このFPCに実装される電子回路と本体回路とを接続して電子回路と本体回路との間でクロック信号等の高周波電流を伝達するため、不要輻射が発生して周辺機器に電気的に悪影響を与えるため、不要輻射対策が施されている。
【0006】
このような不要輻射対策としては、片面FPCの両面に電磁シールドを接着剤によって貼り付けることにより、不要輻射の発生を抑制することが一般的である(例えば、特許文献1参照)。
【0007】
【特許文献1】
特開平7−111371号公報(第2頁、第3頁、図1)
【0008】
【発明が解決しようとする課題】
しかしながら、このような片面FPCにあっては、片面FPCの両面に電磁シールドを接着剤によって貼り付けるようになっていたため、不要輻射の発生を抑えることができるが、厚みが増大してしまい、屈曲を繰り返し行う場合に破断等が発生し易く、耐屈曲性に弱いという問題があった。
【0009】
本発明は、上記従来の問題を解決するもので、不要輻射が発生するのを抑制することができるとともに、耐屈曲性に強いフレキシブル配線基板および前記フレキシブル配線基板を備えた撮像装置を提供することを目的とするものである。
【0010】
【課題を解決するための手段】
本発明のフレキシブル配線基板は、片面に電子回路が実装可能な実装面を有するとともに、前記実装面に前記電子回路に接続可能な配線パターンが形成された回路実装部と、前記回路実装部から前記配線パターンと共に延在し、延在方向端部に本体回路に接続可能な接続部が設けられた長尺部と、前記回路実装部から前記長尺部と異なる方向に延在し、前記実装面の背面に当接するように折り曲げられる折り曲げ部と、前記折り曲げ部に設けられた導電性の平面部材とを有するものから構成される。
【0011】
このような構成により、電子回路が実装された回路実装部の実装面の背面に導電性の平面部材が当接するので、電子回路からの不要輻射を平面部材によって遮蔽することができ、すなわち、平面部材が電磁シールドの機能を果すことにより、不要輻射の発生を抑制することができる。
【0012】
また、フレキシブル配線基板が、片面に配線パターンが形成された片面フレキシブル基板から構成されるので、屈曲を多く繰り返す場合でも破断し難く、耐屈曲性に強いフレキシブル配線基板を提供することができる。
【0013】
また、本発明のフレキシブル配線基板は、前記回路実装部に設けられた複数の配線パターンの一部が前記アース線から構成されるとともに、前記平面部材がアース線に接続されたアース電極から構成される。
【0014】
このような構成により、電子回路が実装された実装面の背面にアース電極が当接するため、配線パターンとアース電極で構成されるループ面積を小さくすることができ、不要輻射をより一層抑制することができる。
【0015】
また、本発明のフレキシブル配線基板は、前記平板部材が前記回路実装部と略同一形状となるように構成される。
【0016】
このような構成により、不要輻射を遮蔽することができる面積を増大させることができるため、不要輻射の発生をより一層抑制することができる。
【0017】
また、本発明のフレキシブル配線基板は、前記折り曲げ部が前記実装面の背面に接着されるように構成される。
【0018】
このような構成により、平面部材と実装面の背面を密着させることができ、不要輻射が電子回路から外部に漏れるのを防止することができる。
【0019】
また、本発明のフレキシブル配線基板は、前記電子回路が実装された前記回路実装部を覆う導電性のハウジングを設けたものから構成される。
【0020】
このような構成により、電子回路がハウジングによってシールドされるので、不要輻射の発生をより一層抑制することができる。
【0021】
また、本発明の撮像装置は、片面に電子回路が実装可能な実装面を有するとともに、前記実装面に前記電子回路に接続可能な配線パターンが形成された回路実装部、前記回路実装部から前記配線パターンと共に延在し、延在方向端部に本体回路に接続可能な接続部が設けられた長尺部、前記回路実装部から前記長尺部と異なる方向に延在し、前記実装面の背面に当接するように折り曲げられる折り曲げ部、および前記折り曲げ部に設けられた導電性の平面部材を有するフレキシブル配線基板と、前記フレキシブル配線基板の前記回路実装部に実装される撮像素子とを備えたものから構成される。
【0022】
このような構成により、電子回路が実装された回路実装部の実装面の背面に導電性の平面部材が当接するので、電子回路からの不要輻射を平面部材によって遮蔽することができ、すなわち、平面部材が電磁シールドの機能を果すことにより、不要輻射の発生を抑制することができる。
【0023】
そして、このようなフレキシブル配線基板に撮像素子を搭載することにより、不要輻射の発生を抑制することができる撮像装置を提供することができる。
【0024】
【発明の実施の形態】
以下、本発明の実施の形態を図面に基づいて説明する。
図1、図2は本発明のフレキシブル配線基板および撮像装置の第1の実施の形態を示す図である。
【0025】
まず、構成を説明する。図1において、FPC1は非導電性のポリイミド等からなるベース2の片面に銅箔からなる配線パターン3が形成されたものから構成されており、回路実装部4、長尺部5および接続部6の部分から構成されている。なお、このFPC1は、例えばデジタルカメラ等の撮像装置に内蔵されるものである。
【0026】
回路実装部4の実装面4aにはCCD撮像素子7、A/Dコンバータ8、画像補正回路9等の電子回路が実装されており、このCCD撮像素子7、A/Dコンバータ8、画像補正回路9の端子は配線パターン3上に接続されている。
【0027】
長尺部5は回路実装部4から配線パターン3と共に延在しており、接続部6は長尺部5の延在方向端部に設けられ、デジタルカメラの図示しない本体回路に配線パターン3が接続されるようになっている。したがって、CCD撮像素子7、A/Dコンバータ8、画像補正回路9は本体回路と配線パターン3を介して接続される。
【0028】
一方、回路実装部4には折り曲げ部10が設けられており、この折り曲げ部10は回路実装部4から長尺部5と異なる方向に延在している。この折り曲げ部10には銅箔からなるアース電極11が設けられており、このアース電極11は回路実装部4と略同一形状に形成されている。
【0029】
折り曲げ部10は回路実装部4の実装面4aの背面に折り曲げられるようになっており、折り曲げ部10は実装面4aの背面に折り曲げられたときに接着剤12によって実装面4aの背面に固定され、アース電極11の全面が回路実装部4に当接するようになっている。なお、配線パターン3の一部はCCD撮像素子7、D/Aコンバータ8、画像補正回路9等を接地するためにアース電極11に接続されるアース線3aから構成されている。
【0030】
このような構成を有するFPC1は、CCD撮像素子7と本体回路の間に介装されており、CCD撮像素子7はピントを合わせるために移動されることから、CCD撮像素子7が光軸方向に移動する度に屈曲される。
【0031】
本実施の形態では、FPC1を片面FPCから構成しているため、屈曲を多く繰り返す場合でも破断し難く、耐屈曲性に強いFPC1を提供することができる。
【0032】
また、CCD撮像素子7等の電子回路が実装された回路実装部4の実装面の背面4aにアース電極11を当接させたので、電子回路からの不要輻射をアース電極11によって遮蔽することができ、すなわち、アース電極11が電磁シールドの機能を果すことにより、不要輻射の発生を抑制することができる。
【0033】
また、回路実装部4の実装面4aの背面にアース電極11を当接させているため、配線パターン3とアース電極11で構成されるループ面積を小さくすることができ、不要輻射をより一層抑制することができる。
【0034】
また、アース電極11を回路実装部4と略同一形状となるように構成したため、不要輻射を遮蔽することができる面積を増大させることができ、不要輻射の発生をより一層抑制することができる。
【0035】
また、折り曲げ部10を実装面4aの背面に接着剤12によって接着したため、アース電極11と実装面4aの背面を密着させることができ、不要輻射が電子回路から外部に漏れるのを防止することができる。
【0036】
また、本実施の形態では、FPC1にCCD撮像素子7を搭載した撮像装置を構成することができるため、不要輻射の発生を抑制することができる撮像装置を提供することができる。
【0037】
なお、本実施の形態では、デジタルカメラに内蔵されたFPC1を例にしているが、このFPC1はコンピュータ機器やOA機器等の各種機器に適用することができることは言うまでもない。
【0038】
図3、図4は本発明のフレキシブル配線基板および撮像装置の第2の実施の形態を示す図である。なお、本実施の形態では、ハウジングを設けた点が第1の実施の形態と異なり、第1の実施の形態と同様の構成には同一番号を付して説明を省略する。
【0039】
図3、図4において、回路実装部4および折り曲げ部10には導電性のハウジング21が取付けられており、このハウジング21はCCD撮像素子7等の電子回路が実装された回路実装部4を覆う本体部22と、本体部22に設けられCCD撮像素子7が突出するように開口する開口部22aと、本体部21の4角から突出し、半田24によって折り曲げ部10が接着固定される4つの脚部23とを備えている。
【0040】
本実施の形態では、折り曲げ部10を回路実装部4の実装面4aの背面に折り曲げて接着剤12によって実装面4aの背面に接着した後、半田24によって折り曲げ部10にハウジング21を接着固定することにより、ハウジング21を回路実装部4と折り曲げ部10に取付けるようになっている。
【0041】
本実施の形態では、電子回路をハウジング21によってシールドすることができるので、不要輻射の発生をより一層抑制することができる。
【0042】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a flexible wiring board on which a wiring pattern is formed and capable of suppressing unnecessary radiation, and an imaging device.
[0002]
[Prior art]
Flexible wiring boards (hereinafter, referred to as FPCs) include a double-sided FPC having a wiring pattern formed on both sides and a single-sided FPC having a wiring pattern formed on one side. The FPC is a digital type because of its thinness and flexibility. It is used in various devices such as cameras and computer devices.
[0003]
Above all, a double-sided FPC is often used to form a relatively large-scale circuit. However, since a double-sided FPC has conductors attached to both sides of a non-conductive material, the production is troublesome. The cost is high, and furthermore, there is a drawback that breakage or the like is liable to occur during repeated bending and weak in bending resistance.
[0004]
For this reason, when mounting an electronic circuit that is relatively easy to manufacture and inexpensive compared to a double-sided FPC and that repeatedly bends, a single-sided FPC is often used.
[0005]
By the way, an FPC connects an electronic circuit mounted on the FPC to a main body circuit and transmits a high-frequency current such as a clock signal between the electronic circuit and the main body circuit. Unnecessary radiation measures are taken to adversely affect the electrical environment.
[0006]
As a countermeasure against such unnecessary radiation, it is common to suppress the generation of the unnecessary radiation by attaching an electromagnetic shield to both surfaces of the single-sided FPC with an adhesive (for example, see Patent Document 1).

However, in such a single-sided FPC, an electromagnetic shield is adhered to both sides of the single-sided FPC with an adhesive, so that generation of unnecessary radiation can be suppressed. When the process is repeatedly performed, there is a problem that breakage and the like are apt to occur and the bending resistance is weak.

With such a configuration, since the conductive planar member abuts on the back surface of the mounting surface of the circuit mounting portion on which the electronic circuit is mounted, unnecessary radiation from the electronic circuit can be shielded by the planar member. When the member performs the function of the electromagnetic shield, the generation of unnecessary radiation can be suppressed.
[0012]
Further, since the flexible wiring substrate is formed of a single-sided flexible substrate having a wiring pattern formed on one surface, it is possible to provide a flexible wiring substrate that is hardly broken even when repeatedly bent and has high bending resistance.

[0017]
Further, the flexible wiring board of the present invention is configured such that the bent portion is adhered to a back surface of the mounting surface.
[0018]
With such a configuration, the flat member and the back surface of the mounting surface can be brought into close contact with each other, and unnecessary radiation can be prevented from leaking from the electronic circuit to the outside.
[0019]
Further, the flexible wiring board according to the present invention is provided with a conductive housing that covers the circuit mounting portion on which the electronic circuit is mounted.
[0020]
With such a configuration, the electronic circuit is shielded by the housing, so that generation of unnecessary radiation can be further suppressed.
[0021]
Further, the imaging device of the present invention has a mounting surface on one side on which an electronic circuit can be mounted, and a circuit mounting portion in which a wiring pattern connectable to the electronic circuit is formed on the mounting surface; A long portion extending with the wiring pattern and having a connection portion connectable to a main body circuit at an end in the extending direction, extending from the circuit mounting portion in a direction different from the long portion, and A bending portion that is bent so as to be in contact with the back surface, a flexible wiring board having a conductive planar member provided in the bending portion, and an imaging element mounted on the circuit mounting portion of the flexible wiring substrate. It is composed of things.
[0022]
With such a configuration, since the conductive planar member abuts on the back surface of the mounting surface of the circuit mounting portion on which the electronic circuit is mounted, unnecessary radiation from the electronic circuit can be shielded by the planar member. When the member performs the function of the electromagnetic shield, the generation of unnecessary radiation can be suppressed.
[0023]
By mounting an image sensor on such a flexible wiring board, it is possible to provide an image pickup apparatus capable of suppressing generation of unnecessary radiation.
