Description

本発明は、プリント配線板、特に補強板付きプリント配線板の製造方法に関する。   The present invention relates to a method for manufacturing a printed wiring board, particularly a printed wiring board with a reinforcing plate.

従来、リジットプリント配線板やフレキシブルプリント配線板においては、電子部品実装部の補強や、コネクタ部の補強の目的で補強板の貼り付けが行われている。補強板の貼り付けは、補強板とリジットプリント配線板あるいはフレキシブルプリント配線板に位置合わせピン嵌合用ガイド孔を設け、このガイド孔に位置合わせピンを挿入することで位置合わせを行う方法が主流をなしている。
しかし、現行のガイド孔を用いる方法では、位置合わせ精度に限界があり、昨今の電子部品の高集積化や製品の小型化の点で障害となっている。
Conventionally, in a rigid printed wiring board and a flexible printed wiring board, a reinforcing plate is attached for the purpose of reinforcing an electronic component mounting portion or a connector portion. The main method of attaching the reinforcing plate is to provide a positioning pin fitting guide hole in the reinforcing plate and the rigid printed wiring board or the flexible printed wiring board, and to perform the positioning by inserting the positioning pin into this guide hole. There is no.
However, the current method using a guide hole has a limit in alignment accuracy, which is an obstacle in the recent high integration of electronic components and the miniaturization of products.

1)ガラス・エポキシ基板の所定箇所に、両面の導通をはかるためのスルーホール用貫 通孔を、ドリルあるいはレーザ等を用いて開口する。
2)得られたガラス・エポキシ基板に無電解メッキ、電解銅メッキを施して前記貫通孔 の内壁面に導通層を形成する。
3)ガラス・エポキシ基板の両面の銅層表面にドライフィルムレジストを貼り付け、所 定のパターンを有するマスクを密接して、紫外線を照射し、その後現像してエッチ ングマスクを作成する。
4)露出している銅層をエッチングし、残存するエッチングマスクを除去して配線部を 形成する。
5)実装に必要なパッド部などを除き、露出している配線部にソルダーレジストを形成 する。
6)必要により一部の外形加工を行う。
7)所望の形状に加工された接着剤付きの補強板と、上記手順1)〜6)により作成され たリジットプリント配線板に設けた少なくとも一対のピン合わせ用ガイド孔を、 貼付け用治具のピンに挿入することで補強板の位置合わせを行ない貼り付ける。
8)熱プレスを使用して、配線板と補強板の間の接着層を仮硬化させ、ボックス炉でベ ーキングを行ない本硬化させる。
9)最終的な形状に外形加工を行って補強板付きのリジットプリント配線板が完成する 。

例えば、従来の補強板の貼り合わせを行うフレキシブルプリント配線板及びリジットプリント配線板の製造方法においては、プリント配線板や補強板の伸縮挙動、ガイド孔の加工精度を考慮して、補強板を貼り合わせる時の位置合わせに使用するガイド孔はピンに対して0.1mm程度大きい直径とする。
このように加工されたフレキシブルプリント配線板及びリジットプリント配線板と補強板の貼り合わせ精度は、ガイド孔の加工精度や補強板の加工精度なども考慮すると、±0.2mm程度が限界であった。
For example, in a conventional method for manufacturing a flexible printed wiring board and a rigid printed wiring board in which a reinforcing board is bonded, the reinforcing board is attached in consideration of the expansion / contraction behavior of the printed wiring board and the reinforcing board and the processing accuracy of the guide hole. The guide hole used for alignment when aligning is made to have a diameter about 0.1 mm larger than the pin.
The bonding accuracy of the flexible printed wiring board and the rigid printed wiring board thus processed and the reinforcing plate is limited to about ± 0.2 mm in consideration of the processing accuracy of the guide hole and the processing accuracy of the reinforcing plate. .

補強板の貼り合わせを行うフレキシブルプリント配線板及びリジットプリント配線板は、位置合わせ精度を考慮した設計を行うことが必要となるが、上記貼り合わせ精度が±0.2mm程度の場合は、現行の電子部品の高密度実装化や製品の小型化の障害になるといわれている。
補強板の貼り合わせ精度を向上させる方法としては、特許文献1に記載のように光学的な合わせマークを使用する方法も提案されているが、従来のピンによる位置合わせのみの場合に比べると、作業時間が長くなるか、或いは新たな装置が必要になることなどが考えられ、コスト面で不利である。
Flexible printed wiring boards and rigid printed wiring boards that bond reinforcing plates need to be designed in consideration of alignment accuracy. If the bonding accuracy is about ± 0.2 mm, the current It is said to be an obstacle to high-density mounting of electronic components and product miniaturization.
As a method of improving the bonding accuracy of the reinforcing plate, a method of using an optical alignment mark as described in Patent Document 1 has also been proposed, but compared with the case of only alignment with a conventional pin, This may be disadvantageous in terms of cost because work time may be increased or a new device may be required.

They are selected to so that.

以下、本発明の実施の形態を図示した実施例に基き説明する。
図1乃至3は本発明の互いに異なる実施例を示しており、何れも、(a)は補強板の平面図、(b)はフレキシブルプリント配線板或いはリジットプリント配線板の平面図、(c)はフレキシブルプリント配線板或いはリジットプリント配線板に補強板を貼り付けた状態の平面図である。図中、1は補強板、2はフレキシブルプリント配線板或いはリジットプリント配線板、3は下記のようにして補強板1に穿設された位置合わせピン嵌合用ガイド孔、4はガイド孔3に対応してリフレキシブルプリント配線板或いはジットプリント配線板2に穿設された位置合わせピン嵌合用ガイド孔、5は図示しない治具上に植設された位置合わせピンである。
Hereinafter, embodiments of the present invention will be described based on the illustrated examples.
1 to 3 show different embodiments of the present invention, in which (a) is a plan view of a reinforcing plate, (b) is a plan view of a flexible printed wiring board or a rigid printed wiring board, and (c). These are the top views of the state which affixed the reinforcement board on the flexible printed wiring board or the rigid printed wiring board. In the figure, 1 is a reinforcing plate, 2 is a flexible printed wiring board or rigid printed wiring board, 3 is a guide hole for positioning pin fitting formed in the reinforcing plate 1 as follows, and 4 corresponds to the guide hole 3 Then, alignment pin fitting guide holes 5 formed in the reflexible printed wiring board or the jit printed wiring board 2 are alignment pins implanted on a jig (not shown).

次に、図1を参照して、特定の場所P(例えば、補強板1の真中)を中心に位置合わせを行う場合について説明する。補強板1の位置合わせピン嵌合用ガイド孔3(図1(a))と、これに対応するフレキシブルプリント配線板或いはリジットプリント配線板2の位置合わせピン嵌合用ガイド孔4(図1(b))を、上記特定の場所Pから見て放射方向(対向する一対の位置合わせピン嵌合用ガイド孔3,3、4,4の中心を通る線分に沿う方向)では、位置合わせピン5(直径:2.0mm)との間のクリアランスが0.12mm以上となるように、また、この線分と直交する方向では上記クリアランスが0.02mmとなるように、それぞれ穿設する。位置合わせピン嵌合用ガイド孔3,3、4,4をこのように形成して、補強板1とフレキシブルプリント配線板或いはリジットプリント配線板2とを図1(c)に示すように貼り合わせるようにすれば、特定の場所での位置ずれを抑制でき、回転ずれも抑制することが可能で、伸縮による位置ズレを最低限とすることができる。   Next, with reference to FIG. 1, the case where it aligns centering on the specific place P (for example, the center of the reinforcement board 1) is demonstrated. Alignment pin fitting guide hole 3 of reinforcing plate 1 (FIG. 1A) and corresponding flexible printed wiring board or rigid printed wiring board 2 alignment pin fitting guide hole 4 (FIG. 1B) ) In the radial direction when viewed from the specific location P (the direction along the line passing through the center of the pair of opposing alignment pin fitting guide holes 3, 3, 4, 4), the alignment pin 5 (diameter : 2.0 mm), and the clearance is 0.12 mm or more, and the clearance is 0.02 mm in the direction perpendicular to the line segment. The alignment pin fitting guide holes 3, 3, 4 and 4 are formed in this way, and the reinforcing plate 1 and the flexible printed wiring board or rigid printed wiring board 2 are bonded together as shown in FIG. By doing so, it is possible to suppress a positional shift at a specific location, to suppress a rotational shift, and to minimize a positional shift due to expansion and contraction.

位置合わせピン嵌合用ガイド孔3,4をそれぞれ上記のような長孔とすることにより、補強板1の伸縮の違いによる同ガイド孔のずれを吸収することが可能となり、丸孔でクリアランスを小さくした時に予想される、位置合わせピン5に補強板1を挿入できなくなるという問題は発生しない。   By making the alignment pin fitting guide holes 3 and 4 long holes as described above, it becomes possible to absorb the deviation of the guide holes due to the expansion and contraction of the reinforcing plate 1, and the clearance is reduced by a round hole. The problem that the reinforcing plate 1 cannot be inserted into the alignment pin 5 is not expected.

また、例えば、貼り付けるべき補強板1が細長く、両端部に位置合わせピン嵌合用ガイド孔3がある場合は、図2に示すように、補強板1のピン嵌合用ガイド孔3とフレキシブルプリント配線板あるいはリジットプリント配線板2の位置合わせピン嵌合用ガイド孔4を長孔にするか、または、特定の場所の位置合わせ精度を求める場合には、図3に示すように、一方の位置合わせピン嵌合用ガイド孔を丸孔6,7とする。
この場合、長孔3,4は、補強板1の幅方向へは位置合わせピン5の直径(2.0mm)より0.02mm大きくし、長手方向へは位置合わせピン5の直径より0.12mm以上大きくする。丸孔6の内径は、位置合わせピン5の直径より0.02mm大きくする。この方法により、伸縮による位置ズレを最低限にすることができる。
Further, for example, when the reinforcing plate 1 to be attached is elongated and there are alignment pin fitting guide holes 3 at both ends, as shown in FIG. 2, the pin fitting guide hole 3 of the reinforcing plate 1 and the flexible printed wiring When the alignment pin fitting guide hole 4 of the board or the rigid printed wiring board 2 is made into a long hole, or when the alignment accuracy of a specific place is to be obtained, as shown in FIG. The fitting guide holes are round holes 6 and 7.
In this case, the long holes 3 and 4 are 0.02 mm larger than the diameter (2.0 mm) of the alignment pin 5 in the width direction of the reinforcing plate 1 and 0.12 mm larger than the diameter of the alignment pin 5 in the longitudinal direction. Make it bigger. The inner diameter of the round hole 6 is 0.02 mm larger than the diameter of the alignment pin 5. By this method, the positional deviation due to expansion and contraction can be minimized.

位置合わせピン嵌合用ガイド孔を上記のように長孔とするのは、補強板1のみのに適用されても良いし、フレキシブルプリント配線板あるいはリジットプリント配線板2のみに適用されても良い。また、位置合わせピン嵌合用ガイド孔を上記のように長孔とする場合のクリアランスは、製造される製品形態などによって任意に設定することができる。また、位置合わせピン嵌合用ガイド孔の数及び/又は位置は、製品の形態に合わせて任意に設定することができる。   Making the alignment pin fitting guide hole as a long hole as described above may be applied only to the reinforcing plate 1, or may be applied only to the flexible printed wiring board or the rigid printed wiring board 2. Further, the clearance when the alignment pin fitting guide hole is a long hole as described above can be arbitrarily set depending on the form of the product to be manufactured. The number and / or position of the alignment pin fitting guide holes can be arbitrarily set according to the form of the product.

以上の説明から明らかなように、本発明方法の最大の特徴は、フレキシブルプリント配線板或いはリジットプリント配線板2に補強板1を貼り付ける際に、補強板1又はフレキシブルプリント配線板或いはリジットプリント配線板2或いはその両者の位置合わせピン嵌合用用ガイド孔を長孔とし、位置合わせピンとガイド孔とのクリアランスの小さい方向と大きい方向を設けることで、従来の位置合わせピンを挿入する方法を用いて、補強板1あるいはフレキシブルプリント配線板或いはリジットプリント配線板2の伸縮の違いにより発生する位置ずれや回転ずれを最低限に抑えることができるようにした点にある。   As is clear from the above description, the greatest feature of the method of the present invention is that when the reinforcing plate 1 is attached to the flexible printed wiring board or the rigid printed wiring board 2, the reinforcing plate 1 or the flexible printed wiring board or the rigid printed wiring is used. Using the conventional method of inserting the alignment pin by making the guide hole for aligning the alignment pin of the plate 2 or both into a long hole and providing a direction in which the clearance between the alignment pin and the guide hole is small and large In addition, the positional deviation and rotational deviation caused by the expansion / contraction difference of the reinforcing plate 1, the flexible printed wiring board or the rigid printed wiring board 2 can be minimized.
