Description

【０００１】
【発明の属する技術分野】
本発明は、金属補強板材料を有する可撓性回路基板の実装用捨て基板と共に出荷する形態であって、金属補強板材料から金属補強板領域を簡便に分離できるようにした可撓性回路基板に於ける補強板の取り付け構造に関する。
【０００２】
【従来の技術とその問題点】
この種の可撓性回路基板に於ける補強板の取り付け構造としては、特開２００２−１６３２５公報のように、金属補強板材料に離脱しないように連結部を介して区画形成した金属補強板の領域に可撓性回路基板の所定箇所を貼付け、その金属補強板と連結部との境界部の両面部位には形成位置が相互に僅かに異なる溝状の分離用スリットを設けたものがある。
【０００３】
しかしこのような構造では、製品側のみに分離部分を設けているので、その連結部位が必ず捨て基板部分に残り、製品のすぐ近傍に破断面が残ることになる。また、この連結部は捨て基板部分と共に実装用ラインに乗せる為、製品とあわせて実装工程を流れることになる。
【０００４】
従って、回路基板の形成後、クリーム半田印刷、部品搭載、リフロ−及び洗浄などの回路基板を実際に使用する為に必要な多くの工程を通過する。このため、工程中で連結部が破断して製品に亀裂、打痕や傷を与える場合があり、また、製品搬出時に連結部が引っかかって工程の一時停止を起こす場合や、連結部の切り離し作業中に金属の鋭利な破断面に触れて負傷する危険性もある。
【０００５】
そこで、本発明は上記不都合を解消できる可撓性回路基板に於ける補強板の取り付け構造を提供するものである。
【０００６】
【課題を解決するための手段】
その為に本発明に係る可撓性回路基板に於ける補強板の取り付け構造では、金属補強板材料に離脱しないように連結部を介して区画形成した金属補強板の領域に可撓性回路基板の所定箇所を貼付け、前記金属補強板と前記連結部との境界部及び前記連結部と捨て基板部との境界部のそれぞれの両面部位には形成位置が相互に僅かに異なる溝状の分離用スリットを設けるように構成したものである。
【０００７】
ここで、前記連結部にはこの連結部の分離を容易化する為の切り欠き部を設けることができ、また、前記溝状の分離用スリットはエッチング手段で同時に形成することができる。
【０００８】
【発明の実施の形態】
以下、図示の実施例を参照しながら本発明を更に説明する。図１は本発明による可撓性回路基板に於ける補強板の取り付け構造の要部平面構成図であって、１は可撓性回路基板を含む製品部を示し、２はこの製品部１を連結部３を介して一体に支持する為の捨て基板部である。
【０００９】
可撓性回路基板はその所定箇所が、金属補強板材料に離脱しないように連結部３を介して区画形成した金属補強板の領域に貼付けられており、連結部３も金属補強板材料により一体に形成されている。
【００１０】
そして、製品部１に於ける金属補強板と連結部３との境界部及び連結部３と捨て基板部２との境界部のそれぞれの両面部位には形成位置が相互に僅かに異なる溝状の分離用スリット４を両面同時のエッチング手段で設けるように構成してある。
【００１１】
このように連結部３の両端に溝状の分離用スリット４を設けることによって、連結部３の分離は容易となり、また、他の部分に可撓性回路基板のみで接続部分を設けることにより実装工程前に破断部分を取り除くことができるので、既述した従来の不具合を好適に防止できる。
【００１２】
しかし、上記のように分離用スリット４を連結部３の両端に設けただけでは、この連結部３の特性上、一方の分離用スリット４の部分で破断すると他方の分離用スリット４の部分が容易に変形して連結部３が離脱しない場合がある。
【００１３】
そこで、連結部３の中央部などに穴状の切り欠き部５を形成し、この切り欠き部５に適当な治具等を押し当てると、上記のような不具合を生ずることなく確実に連結部３の分離を行える。
【００１４】
このような切り欠き部は、図２に示すように連結部３の中央部両側に矩形状の切り欠き部６に形成してもよく、また、図３のようにＶ字状の切り欠き部７に形成してもよく、いずれにしても連結部３を押す治具等がその切り欠き部に嵌合して分離用スリット４に引っ張り力がかかる形状であればその他の任意の形状を採用できる。
【００１５】
【発明の効果】
本発明に係る可撓性回路基板に於ける補強板の取り付け構造によれば、補強板として金属補強板材料を使用しても製品部と捨て基板部との連結部を容易確実に分離できる。
【００１６】
従って、製品の傷、亀裂、打痕の防止など品質の向上を図れるほか、プレス工程やバリ取り作業の削除など工程の省略ができ、また、金属板打ち抜きの為の型も不要であるなどの工具の簡易化も図れる。

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a flexible circuit board which is shipped together with a disposal board for mounting a flexible circuit board having a metal reinforcing board material, wherein the metal reinforcing board area can be easily separated from the metal reinforcing board material. The mounting structure of the reinforcing plate in the above.
[0002]
[Conventional technology and its problems]
As a mounting structure of a reinforcing plate in a flexible circuit board of this type, as disclosed in Japanese Patent Application Laid-Open No. 2002-16325, a metal reinforcing plate partitioned and formed via a connecting portion so as not to separate from a metal reinforcing plate material is used. In some cases, a predetermined portion of the flexible circuit board is attached to the region, and groove-shaped separating slits whose formation positions are slightly different from each other are formed on both sides of the boundary between the metal reinforcing plate and the connecting portion.
[0003]
However, in such a structure, since the separation portion is provided only on the product side, the connection portion always remains on the discarded substrate portion, and a fracture surface remains immediately near the product. In addition, since this connecting portion is put on the mounting line together with the discarded substrate portion, the mounting process flows together with the product.
[0004]
Therefore, after the formation of the circuit board, it goes through many steps required for actually using the circuit board, such as cream solder printing, component mounting, reflow and cleaning. For this reason, the connecting part may be broken during the process, causing cracks, dents or scratches on the product.The connecting part may be caught when the product is carried out, causing a temporary stop in the process, or disconnecting the connecting part. There is also a danger of being injured by touching a sharp metal fracture surface.
[0005]
Therefore, the present invention provides a structure for mounting a reinforcing plate on a flexible circuit board which can solve the above-mentioned disadvantages.
[0006]
[Means for Solving the Problems]
Therefore, in the mounting structure of the reinforcing plate in the flexible circuit board according to the present invention, the flexible circuit board is formed in a region of the metal reinforcing plate partitioned and formed via the connecting portion so as not to be separated from the metal reinforcing plate material. A predetermined position is stuck on the boundary between the metal reinforcing plate and the connection part and the boundary between the connection part and the discarded substrate part on both sides of the groove. It is configured to provide a slit.
[0007]
Here, the connecting portion may be provided with a notch for facilitating separation of the connecting portion, and the groove-shaped separating slit may be formed simultaneously by etching means.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be further described with reference to the illustrated embodiments. FIG. 1 is a plan view of a main part of a mounting structure of a reinforcing plate in a flexible circuit board according to the present invention, wherein 1 denotes a product section including the flexible circuit board, and 2 denotes a product section. It is a discarded substrate part for integrally supporting via the connecting part 3.
[0009]
A predetermined portion of the flexible circuit board is affixed to a region of the metal reinforcing plate partitioned and formed via the connecting portion 3 so as not to be separated from the metal reinforcing plate material, and the connecting portion 3 is also integrated with the metal reinforcing plate material. Is formed.
[0010]
A groove-shaped part whose formation position is slightly different from each other is formed on both sides of the boundary between the metal reinforcing plate and the connection part 3 and the boundary between the connection part 3 and the discarded substrate part 2 in the product part 1. The separation slit 4 is provided by means of simultaneous etching on both sides.
[0011]
By providing the groove-shaped separating slits 4 at both ends of the connecting portion 3 in this manner, the connecting portion 3 can be easily separated, and mounting is performed by providing a connecting portion only with a flexible circuit board in other portions. Since the broken portion can be removed before the process, the above-mentioned conventional problems can be suitably prevented.
[0012]
However, if the separating slits 4 are provided only at both ends of the connecting portion 3 as described above, due to the characteristics of the connecting portion 3, if one of the separating slits 4 breaks, the other separating slit 4 portion will break. There is a case where the connecting portion 3 is not easily detached due to deformation.
[0013]
Accordingly, a hole-shaped notch 5 is formed at the center of the connecting portion 3 and the like, and an appropriate jig or the like is pressed against the notch 5 so that the connecting portion can be reliably formed without the above-described problem. 3 can be performed.
[0014]
Such a notch may be formed in a rectangular notch 6 on both sides of the central portion of the connecting portion 3 as shown in FIG. 2, or a V-shaped notch as shown in FIG. In any case, any other shape may be used as long as a jig or the like that presses the connecting portion 3 fits into the cutout portion and applies a pulling force to the separation slit 4. it can.
[0015]
【The invention's effect】
According to the mounting structure of the reinforcing plate in the flexible circuit board according to the present invention, the connecting portion between the product section and the discarded board section can be easily and reliably separated even if a metal reinforcing plate material is used as the reinforcing plate.
[0016]
Therefore, it is possible to improve the quality such as prevention of scratches, cracks and dents on the product, and to omit the steps such as the pressing process and the deburring work, and it is not necessary to use the mold for punching the metal plate. The tool can be simplified.
