Description
本発明は、補強板付フレキシブル回路板の補強板が所定の厚さであるかどうかを検出する検出方法および検出システムに関する。 The present invention relates to a detection method and a detection system for detecting whether a reinforcing plate of a flexible circuit board with a reinforcing plate has a predetermined thickness.
薄型軽量という特長を生かして、電子機器内にはフレキシブル回路板が多用されている。フレキシブル回路板は、一般には以下のようにして作成される。まず、基材としてポリイミド樹脂フィルムと、金属箔として一般的に銅箔とを貼り合せた、フレキシブル回路板用積層板を用意する。次に、銅箔をエッチング等によりパターンニングし導体回路を形成する。 Taking advantage of the thin and lightweight features, flexible circuit boards are frequently used in electronic devices. The flexible circuit board is generally produced as follows. First, a laminate for a flexible circuit board is prepared, in which a polyimide resin film is bonded as a base material and a copper foil is generally bonded as a metal foil. Next, the copper foil is patterned by etching or the like to form a conductor circuit.
次に、絶縁被覆層として、予め導体回路露出個所を打抜き金型等を用いて取り除いた、ポリイミド樹脂フィルムの一方の面に熱硬化性接着剤が塗布されたカバーレイフィルムを導体回路側に貼り合せる。最後に、必要により露出した部分にめっきを施したり、強度が必要な部分に補強板を貼着したりして完成となる（例えば特許文献１）。 Next, a coverlay film with a thermosetting adhesive applied to one side of the polyimide resin film, where the exposed portions of the conductor circuit were previously removed using a punching die or the like, was applied to the conductor circuit side as an insulating coating layer. Match. Finally, the exposed portion is plated if necessary, or a reinforcing plate is attached to a portion requiring strength (for example, Patent Document 1).
しかし、近年、実装の高密度化が促進し、加工精度の向上は行われているものの、強度が必要な個所に貼着する補強板は、依然として人的作業によっている。そのため、補強板を間違って複数枚貼着するなどの問題があったが、これまでは作業者自信が確認したりしていたため、時折次工程に流出し、例えば部品に組み込むときに発見されることがあった。

以下、補強板付フレキシブル回路板１２０を構成する各部について説明する。 Hereinafter, each part which comprises the flexible circuit board 120 with a reinforcement board is demonstrated.
補強板付フレキシブル回路板１２０は、補強板２００とフレキシブル回路板１００とから構成されている。補強板２００としては、特に限定されるものではないが、例えば、ポリイミド樹脂フィルム、ポリエーテルイミド樹脂フィルム、ポリアミドイミド樹脂フィルム等のポリイミド樹脂系樹脂フィルム、ポリアミド樹脂フィルム等のポリアミド樹脂系フィルム、ポリエステル樹脂フィルム等のポリエステル樹脂系フィルムなどの樹脂フィルムが挙げられる。また、ガラス織布、ガラス不織布などにエポキシ系樹脂を含浸硬化させたガラスエポキシ基板や、紙基材に、エポキシ樹脂やフェノール樹脂などを含浸硬化させた紙エポキシ基板や紙フェノール基板などを用いることもできる。補強板２００の厚さは、特に限定はされないが、０．０２５ｍｍ〜１．６ｍｍが好ましく用いられる。 The flexible circuit board 120 with the reinforcing plate is composed of the reinforcing plate 200 and the flexible circuit board 100. The reinforcing plate 200 is not particularly limited. For example, a polyimide resin film such as a polyimide resin film, a polyetherimide resin film, a polyamideimide resin film, a polyamide resin film such as a polyamide resin film, a polyester, etc. A resin film such as a polyester resin film such as a resin film may be used. Also, use glass epoxy substrates impregnated and cured with epoxy resin in glass woven fabric, glass nonwoven fabric, etc., and paper epoxy substrates and paper phenol substrates in which epoxy resin or phenol resin is impregnated and cured for paper base materials. You can also. The thickness of the reinforcing plate 200 is not particularly limited, but 0.025 mm to 1.6 mm is preferably used.
フレキシブル回路板１００は、基材１５０と、基材１５０の面に導体回路１３０が形成されている。導体回路１３０のうち、検出に用いる導体パッド１３２は、導体回路１３０の一部を利用したものである。また、導体回路１３０と導体パッド１３２は、一部を残して表面被覆材で覆われている。 The flexible circuit board 100 has a base 150 and a conductor circuit 130 formed on the surface of the base 150. Of the conductor circuit 130, the conductor pad 132 used for detection uses a part of the conductor circuit 130. Further, the conductor circuit 130 and the conductor pad 132 are covered with a surface covering material, leaving a part.
基材１５０を構成する材料としては、例えば樹脂フィルム基材等が挙げられる。樹脂フィルム基材としては、例えばポリイミド樹脂フィルム、ポリエーテルイミド樹脂フィルム、ポリアミドイミド樹脂フィルム等のポリイミド樹脂系樹脂フィルム、ポリアミド樹脂フィルム等のポリアミド樹脂系フィルム、ポリエステル樹脂フィルム等のポリエステル樹脂系フィルムが挙げられる。このうち、弾性率と耐熱性を向上させる観点から、特にポリイミド樹脂系フィルムが好ましく用いられる。 Examples of the material constituting the substrate 150 include a resin film substrate. Examples of the resin film substrate include polyimide resin films such as polyimide resin films, polyetherimide resin films, polyamideimide resin films, polyamide resin films such as polyamide resin films, and polyester resin films such as polyester resin films. Can be mentioned. Of these, a polyimide resin film is particularly preferably used from the viewpoint of improving the elastic modulus and heat resistance.
基材１５０の厚さは、特に限定されないが、５〜５０μｍが好ましく、特に１２．５〜２５
μｍが好ましい。厚さがこの範囲内であると、特に屈曲性に優れる。
Although the thickness of the base material 150 is not specifically limited, 5-50 micrometers is preferable and especially 12.5-25.
μm is preferred. When the thickness is within this range, the flexibility is particularly excellent.
表面被覆材は、樹脂フィルム１１０と接着剤１７０で構成されたカバーレイフィルムでもよいし、熱硬化性樹脂を含む液状体の樹脂組成物をスクリーン印刷法などにより形成し加熱硬化してもよい。曲げ特性の面からカバーレイフィルムを用いることが好ましい。図１では、表面被覆材として、カバーレイフィルムを例示として挙げている。また、図示はしていないがフレキシブル回路板１００と補強板２００の間には接着層が設けられこの接着層を介して接着されている。 The surface covering material may be a cover lay film composed of the resin film 110 and the adhesive 170, or a liquid resin composition containing a thermosetting resin may be formed by screen printing or the like and cured by heating. It is preferable to use a coverlay film from the viewpoint of bending characteristics. In FIG. 1, a coverlay film is exemplified as the surface covering material. Further, although not shown, an adhesive layer is provided between the flexible circuit board 100 and the reinforcing board 200 and is bonded via this adhesive layer.
次に、センサー３００を構成する各部について説明する。 Next, each part which comprises the sensor 300 is demonstrated.
センサー３００は、進退自在に形成され、かつ、先端側は、貫通孔２０２に挿入可能な棒状体３２３を備える電極３０３を有している。センサー３００は、一般にプリント回路板の導体回路間の断線、短絡の確認用に用いられる電気検査治具と特に変わることころはない。センサーの基端側３２７は、補強板２００に設けられた貫通孔２０２よりも径が大きく、先端側は棒状体３２３になっており、基端側３２７が、補強板２００と当接した状態で、補強板２００が所定の厚さの時は先端部３２３１が導体パッド１３２と接触し、補強板２００が所定の厚さより厚いときは接触しないような長さになっている。また、棒状体３２３の基端側には弾性体３２５が設けられ、一定の圧力で導体パッド１３２と接触することによりより確実に導通確認ができるようにしてもよい。弾性体としては、特に限定はされないが、バネやゴムなど反復使用可能な部材を使用することが好ましい。 The sensor 300 is formed so as to be able to advance and retreat, and has an electrode 303 provided with a rod-like body 323 that can be inserted into the through hole 202 on the distal end side. The sensor 300 is not particularly different from an electric inspection jig generally used for confirming disconnection or short circuit between conductor circuits of a printed circuit board. The base end side 327 of the sensor is larger in diameter than the through hole 202 provided in the reinforcing plate 200, the tip end side is a rod-shaped body 323, and the base end side 327 is in contact with the reinforcing plate 200. When the reinforcing plate 200 has a predetermined thickness, the distal end portion 3231 is in contact with the conductor pad 132, and when the reinforcing plate 200 is thicker than the predetermined thickness, the length is such that it does not contact. Further, an elastic body 325 may be provided on the base end side of the rod-shaped body 323 so that the conduction can be confirmed more reliably by contacting the conductor pad 132 with a constant pressure. The elastic body is not particularly limited, but it is preferable to use a reusable member such as a spring or rubber.
また、電極３０３も基端側３２７が膨らんだ形状でなく、電極３０３が装着されている治具板が補強板２００と当接するように棒状体３２３の長さを調整してもよい。治具板を補強板２００と当接するようにすることで、基端側３２７の径が大きい電極３０３を用いなくとも済むという効果がある。電極３０３には、電線３１０が接続してあり、検出器によって電気的な接続を確認できるようになっている。また、棒状体３２３の先端部３２３１は、特に限定はされないが、針状になっていることが好ましい。 Further, the length of the rod-shaped body 323 may be adjusted so that the base plate 327 is not swelled in the electrode 303 and the jig plate on which the electrode 303 is mounted comes into contact with the reinforcing plate 200. By bringing the jig plate into contact with the reinforcing plate 200, there is an effect that it is not necessary to use the electrode 303 having a large diameter on the base end side 327. An electric wire 310 is connected to the electrode 303 so that the electrical connection can be confirmed by a detector. Further, the distal end portion 3231 of the rod-shaped body 323 is not particularly limited, but preferably has a needle shape.
次に、検出する方法について説明する。 Next, a detection method will be described.
検出方法は、以下の２つのステップに分けることができる。 The detection method can be divided into the following two steps.
第一のステップは、棒状体３２３を、貫通孔２０２の内部に挿入しつつ、棒状体３２３の基端側３２７を補強板２００面に当接させるステップである。 The first step is a step of bringing the proximal end 327 of the rod-shaped body 323 into contact with the reinforcing plate 200 surface while inserting the rod-shaped body 323 into the through hole 202.
第二のステップは、棒状体３２３の基端側３２７を補強板２００面に当接させたとき、補強板２００が所定の厚さであるとき、電極３０３の先端部３２３１が導体パッド１３２に接触し、接触したことを報知する。例えば、補強板２００が所定の厚さより厚いとき、電極３０３の先端部３２３１と導体パッド１３２は離間したままとなり報知することがない。 In the second step, when the proximal end 327 of the rod-shaped body 323 is brought into contact with the surface of the reinforcing plate 200, the distal end portion 3231 of the electrode 303 contacts the conductor pad 132 when the reinforcing plate 200 has a predetermined thickness. Then, the contact is notified. For example, when the reinforcing plate 200 is thicker than a predetermined thickness, the tip end portion 3231 of the electrode 303 and the conductor pad 132 remain separated from each other and no notification is given.
図２は、本発明による検出方法の他の実施形態を示す断面図であり、図２（ａ）は、補強板の厚さが適切である場合を、図２（ｂ）は、補強板の厚さが適切でない場合を示す図である。。この場合の検出方法は、上述の実施形態とは異なり、フレキシブル回路板１００に設けられた導体パッド１３２とセンサー３００を当接して、補強板２００の厚さが適切であるかを検出するのではなく、フレキシブル回路板１００と補強板２００とを貫通する貫通孔１０２、２０２と対向するように検出部分が設けられている。 FIG. 2 is a cross-sectional view showing another embodiment of the detection method according to the present invention. FIG. 2A shows a case where the thickness of the reinforcing plate is appropriate, and FIG. It is a figure which shows the case where thickness is not appropriate. . Unlike the above-described embodiment, the detection method in this case is to contact the conductor pads 132 provided on the flexible circuit board 100 and the sensor 300 to detect whether the thickness of the reinforcing plate 200 is appropriate. The detection portion is provided so as to face the through holes 102 and 202 that penetrate the flexible circuit board 100 and the reinforcing plate 200.
フレキシブル回路板１００と、フレキシブル回路板１００の少なくとも一方の面側に補強板２００とを貼着してなり、補強板２００には少なくとも一つの第一の貫通孔２０２が設けられるとともに、フレキシブル回路板１００には、第一の貫通孔２０２に対応するように第二の貫通孔１０２が設けられている。 The flexible circuit board 100 and a reinforcing board 200 are attached to at least one surface side of the flexible circuit board 100.

以下、補強板付フレキシブル回路板１２０を構成する各部について説明する。 Hereinafter, each part which comprises the flexible circuit board 120 with a reinforcement board is demonstrated.
補強板付フレキシブル回路板１２０は、補強板２００とフレキシブル回路板１００とから構成されている。補強板２００としては、特に限定されるものではないが、例えば、ポリイミド樹脂フィルム、ポリエーテルイミド樹脂フィルム、ポリアミドイミド樹脂フィルム等のポリイミド樹脂系樹脂フィルム、ポリアミド樹脂フィルム等のポリアミド樹脂系フィルム、ポリエステル樹脂フィルム等のポリエステル樹脂系フィルムなどの樹脂フィルムが挙げられる。また、ガラス織布、ガラス不織布などにエポキシ系樹脂を含浸硬化させたガラスエポキシ基板や、紙基材に、エポキシ樹脂やフェノール樹脂などを含浸硬化させた紙エポキシ基板や紙フェノール基板などを用いることもできる。補強板２００の厚さは、特に限定はされないが、０．０２５ｍｍ〜１．６ｍｍが好ましく用いられる。 The flexible circuit board 120 with the reinforcing plate is composed of the reinforcing plate 200 and the flexible circuit board 100. The reinforcing plate 200 is not particularly limited. For example, a polyimide resin film such as a polyimide resin film, a polyetherimide resin film, a polyamideimide resin film, a polyamide resin film such as a polyamide resin film, a polyester, etc. A resin film such as a polyester resin film such as a resin film may be used. Also, use glass epoxy substrates impregnated and cured with epoxy resin in glass woven fabric, glass nonwoven fabric, etc., and paper epoxy substrates and paper phenol substrates in which epoxy resin or phenol resin is impregnated and cured for paper base materials. You can also. The thickness of the reinforcing plate 200 is not particularly limited, but 0.025 mm to 1.6 mm is preferably used.
次に、センサー３００を構成する各部について説明する。 Next, each part which comprises the sensor 300 is demonstrated.
センサー３００は、固定されている第二の電極３２１と、進退自在に形成され、かつ、先端側は、貫通孔１０２、２０２に挿入可能な棒状体３２３を備える第二の電極３０３を有している。センサー３００は、一般にプリント回路板の導体回路間の断線、短絡の確認用に用いられる電気検査治具と特に変わることころはない。センサーの基端側３２７は、補強板２００およびフレキシブル回路板１００に設けられた貫通孔２０２よりも径が大きく、先端側は棒状体３２３になっており、基端側３２７が、補強板２００と当接した状態で、補強板２００が所定の厚さの時は棒状体３２３１が導体パッド１３２と接触し、補強板２００が所定の厚さより厚いときは接触しないような長さになっている。また、棒状体３２３の基端側には弾性体３２５が設けられ、一定の圧力で第二の電極３２１と接触することによりより確実に導通確認ができるようにしてもよい。弾性体としては、特に限定はされないが、バネやゴムなど反復使用可能な部材を使用することが好ましい。 The sensor 300 includes a second electrode 321 that is fixed, and a second electrode 303 that is formed so as to be able to advance and retreat, and has a rod-like body 323 that can be inserted into the through holes 102 and 202 on the distal end side. Yes. The sensor 300 is not particularly different from an electric inspection jig generally used for confirming disconnection or short circuit between conductor circuits of a printed circuit board. The base end side 327 of the sensor is larger in diameter than the through hole 202 provided in the reinforcing plate 200 and the flexible circuit board 100, the tip end side is a rod-shaped body 323, and the base end side 327 is connected to the reinforcing plate 200. When the reinforcing plate 200 has a predetermined thickness in the abutting state, the rod-shaped body 3231 is in contact with the conductor pad 132, and when the reinforcing plate 200 is thicker than the predetermined thickness, the length is such that it does not contact. Further, an elastic body 325 may be provided on the base end side of the rod-shaped body 323 so that the conduction can be confirmed more reliably by contacting the second electrode 321 with a constant pressure. The elastic body is not particularly limited, but it is preferable to use a reusable member such as a spring or rubber.
また、第一の電極３０３も基端側３２７が膨らんだ形状でなく、電極３０３が装着されている治具板が補強板２００と当接するように棒状体３２３の長さを調整してもよい。治具板を補強板２００と当接するようにすることで、基端側３２７の径が大きい第一の電極３０３を用いなくとも済むという効果がある。第一および第二の電極３０３、３２１には、それぞれ電線３１０が接続し、検出器につながっており、検出器によって電気的な接続を確認できるようになっている。また、棒状体３２３の先端部３２３１は、特に限定はされないが、針状になっていることが好ましい。 Also, the length of the rod-shaped body 323 may be adjusted so that the first electrode 303 does not have a shape in which the proximal end side 327 swells, and the jig plate on which the electrode 303 is mounted contacts the reinforcing plate 200. . By bringing the jig plate into contact with the reinforcing plate 200, there is an effect that it is not necessary to use the first electrode 303 having a large diameter on the base end side 327. An electric wire 310 is connected to each of the first and second electrodes 303 and 321 and is connected to a detector so that the electrical connection can be confirmed by the detector. Further, the distal end portion 3231 of the rod-shaped body 323 is not particularly limited, but preferably has a needle shape.
次に、検出する方法について説明する。 Next, a detection method will be described.
検出方法は、以下の２つのステップに分けることができる。 The detection method can be divided into the following two steps.
第一のステップは、棒状体３２３を、貫通孔１０２、２０２の内部に挿入しつつ、棒状体３２３の基端側３２７を補強板２００面に当接させるステップである。 The first step is a step of bringing the base end side 327 of the rod-shaped body 323 into contact with the reinforcing plate 200 surface while inserting the rod-shaped body 323 into the through holes 102 and 202.
第二のステップは、棒状体３２３の基端側３２７を補強板２００面に当接させたとき、補強板２００が所定の厚さであるとき、電極３０３の先端部が第二の電極３２１に接触し、接触したことを報知する。例えば、補強板２００が所定の厚さより厚いとき、第一の電極３０３の先端部３２３１と第二の電極３２１は離間したままとなり報知することがない。 In the second step, when the proximal end 327 of the rod-shaped body 323 is brought into contact with the surface of the reinforcing plate 200, the distal end portion of the electrode 303 becomes the second electrode 321 when the reinforcing plate 200 has a predetermined thickness. It contacts and it notifies that it contacted. For example, when the reinforcing plate 200 is thicker than a predetermined thickness, the distal end portion 3231 of the first electrode 303 and the second electrode 321 remain separated from each other and no notification is given.
