光モジュール等の光通信に用いる機器では、光学部品の組み立てにミクロンオーダの高精度の位置合わせ（調心）が要求され、光素子等を動作状態にしてアクティブに調心することが必要とされている。しかし、この調心方法は、調心装置を必要とすると共に調心に時間を要するため、コスト高なものとなる。これに対し、図６に示すような方法によれば、機械的に位置決めができるが、位置決めのためのガイド穴やガイド突起の加工を高精度で行う必要があり、加工方法によっては十分な位置決め精度が得られず、このためのコストを要している。   Devices used for optical communications such as optical modules require micron-order high-precision alignment (alignment) for assembly of optical components, and it is necessary to actively align optical elements and the like in an operating state. ing. However, this aligning method requires a aligning device and requires time for aligning, and is expensive. On the other hand, according to the method shown in FIG. 6, the positioning can be performed mechanically, but it is necessary to process the guide holes and the guide projections for positioning with high accuracy. The accuracy is not obtained, and the cost for this is required.

また、特許文献２には、光学部品の組み立に吸着手段を用いることが開示されているが、組み込み部品自体に吸着口や吸引口を設けるため、部品形状が大型化するという問題がある。また、この場合も、部品間の位置決めは、部品に設けたマーカやパワーメータを用いて行うため、光学系の調心には時間を要している。   Patent Document 2 discloses the use of a suction means for assembling an optical component. However, since the built-in component itself is provided with a suction port and a suction port, there is a problem that the size of the component increases. Also in this case, since positioning between components is performed using a marker or a power meter provided on the components, it takes time to align the optical system.

本発明は上述した実状に鑑みてなされたもので、複数の光素子が列状に配列された光素子アレイを備える光学部品に位置合わせのための加工を施したり、調心装置を用いたりすることなく光学部品との高精度の調心ができ、しかも、光学部品の調心状態の保持が効果的に行える光学部品の実装方法の提供を目的とする。 The present invention has been made in view of the above-described situation, and performs processing for alignment or uses an aligning device on an optical component including an optical element array in which a plurality of optical elements are arranged in a row. it can highly accurate alignment with no optical components, moreover, and an object thereof is to provide a mounting method of the optical engine's service life holding the alignment state of the optical component that can effectively.

本発明による光学部品の実装方法は、複数の光素子が列状に配列された光素子アレイを備える光学部品を実装基板に位置決めして実装する方法であって、前記光素子アレイの両端側に位置する少なくとも２つの光素子をそれぞれ観察する少なくとも２つの視認用の孔と、該視認用の孔に交差するように連通し前記光学部品を吸着するための吸引用の孔と、を備え、前記視認用の孔は、治具本体部の吸着面と視認面に開口するよう貫通形成されており、前記視認面における開口は透明蓋により閉塞されている光学部品調心治具を用意し、前記光素子アレイの両端側に位置する２つの光素子を２つの前記視認用の孔から視認し、前記２つの光素子と２つの前記視認用の孔がそれぞれ一致するように調心した後、前記光学部品を前記吸引用の孔からの吸引により吸着保持して、前記基板に位置決めして実装することを特徴とする。なお、光学部品調心治具は、光学部品を実装基板に位置決めして実装するガイド手段を備えている。
An optical component mounting method according to the present invention is a method of positioning and mounting an optical component including an optical element array in which a plurality of optical elements are arranged in a row on a mounting substrate, and is mounted on both ends of the optical element array. At least two viewing holes for observing each of the at least two optical elements positioned; and suction holes for communicating with the viewing holes so as to adsorb the optical component, A hole for visual recognition is formed so as to open to the suction surface and the visual recognition surface of the jig main body, and an opening in the visual recognition surface is prepared as an optical component aligning jig closed by a transparent lid, After viewing two optical elements located on both ends of the optical element array from the two viewing holes, and aligning the two optical elements and the two viewing holes, respectively , Optical component from the suction hole Adsorbed and held by suction, characterized by mounting to position the substrate.

図１により、本発明に用いる光学部品調心治具（以下、単に治具という）の一例を説明する。図中、１０は治具、１１は光学部品、１１ａは光素子、１２は治具本体、１２ａは吸着面、１２ｂは視認面、１２ｃは吸引面、１３ａ，１３ｂは視認用孔、１４ａ，１４ｂは吸引用孔、１５は透明蓋、１６ａ，１６ｂはガイド孔、１７ａ、１７ｂはガイドピンを示す。 An example of an optical component alignment jig (hereinafter simply referred to as a jig) used in the present invention will be described with reference to FIG. In the figure, 10 is a jig, 11 is an optical component, 11a is an optical element, 12 is a jig body, 12a is a suction surface, 12b is a viewing surface, 12c is a suction surface, 13a and 13b are viewing holes, and 14a and 14b. Is a suction hole, 15 is a transparent lid, 16a and 16b are guide holes, and 17a and 17b are guide pins.

本発明に用いる治具１０は、光学部品１１を吸着して保持し、ガイド孔１６ａ，１６ｂとガイドピン１７ａ，１７ｂによるガイド手段で、光学部品１１を実装基板上の所定位置に位置決めして実装するのに用いられる。光学部品１１は、多数の発光素子または受光素子（例えば、１２素子）からなる光素子１１ａを列状に配列した光素子アレイを備える。なお、各光素子１１ａは、光学部品１１の半導体基板に直接作り込まれたものとすることができる。 The jig 10 used in the present invention sucks and holds the optical component 11 and positions and mounts the optical component 11 at a predetermined position on the mounting substrate by guide means using guide holes 16a and 16b and guide pins 17a and 17b. Used to do. The optical component 11 includes an optical element array in which optical elements 11a including a large number of light emitting elements or light receiving elements (for example, 12 elements) are arranged in a line. In addition, each optical element 11a can be made directly on the semiconductor substrate of the optical component 11.

治具１０は、セラミックや樹脂等で成形された矩形状のブロックからなる治具本体１２と、透明樹脂等の透明蓋１５とで構成される。治具本体１２は、矩形状側面の４面の１つを光学部品の吸着面１２ａとし、該吸着面と反対側の面を視認面１２ｂとし、吸着面１２ａと視認面１２ｂと異なる面の１つを吸引面１２ｃとしている。そして、少なくとも２つの視認用孔１３ａと１３ｂが、吸着面１２ａから視認面１２ｂを貫通するように設けられる。なお、視認用孔１３ａと１３ｂは、例えば、光学部品１１の一列に配列された光素子１１ａの両端に位置する光素子１１ａ’と一致するように形成される。   The jig 10 includes a jig body 12 made of a rectangular block formed of ceramic, resin, or the like, and a transparent lid 15 made of transparent resin or the like. The jig body 12 has one of the four rectangular side surfaces as the suction surface 12a of the optical component, the surface opposite to the suction surface as the viewing surface 12b, and a surface different from the suction surface 12a and the viewing surface 12b. One is a suction surface 12c. Then, at least two viewing holes 13a and 13b are provided so as to penetrate the viewing surface 12b from the suction surface 12a. The visual recognition holes 13a and 13b are formed so as to coincide with the optical elements 11a 'located at both ends of the optical elements 11a arranged in a line of the optical component 11, for example.

吸引用孔１４ａ，１４ｂは、一端が吸引面１２ｃに通じ、他端が視認用孔１３ａ，１３ｂに交差し連通するように形成される。そして、視認面１２ｂには透明蓋１５が接合され、透視可能に視認用孔１３ａ，１３ｂの視認面側が封鎖される。これにより、吸引用孔１４ａ，１４ｂは、吸着面１２ａ側に通じるようになる。また、治具１０には、その両端部にガイド孔１６ａと１６ｂが設けられていて、光学部品１１を実装する実装基板に設けられたガイドピン１７ａと１７ｂに嵌合挿通させることにより、位置決めされるようになっている。   The suction holes 14a and 14b are formed so that one end communicates with the suction surface 12c and the other end intersects and communicates with the viewing holes 13a and 13b. And the transparent cover 15 is joined to the visual recognition surface 12b, and the visual recognition surface side of the visual recognition holes 13a and 13b is sealed so that it can see through. As a result, the suction holes 14a and 14b lead to the suction surface 12a side. The jig 10 is provided with guide holes 16a and 16b at both ends thereof, and is positioned by being fitted and inserted into guide pins 17a and 17b provided on a mounting board on which the optical component 11 is mounted. It has become so.

なお、透明蓋１５は視認用孔１３ａ，１３ｂの視認面側を封鎖した状態で、吸着面側に配置される光学部品１１（光素子１１ａ）を視認可能であればよく、例えば、ガラス板や透明プラスチック板で形成するのが好適である。また、治具１０にガイド孔１６ａと１６ｂが設けられている場合には、透明蓋１５にもガイド孔１６ａと１６ｂが連通して形成されているのが好適であるが、透明蓋１５には必ずしもガイド孔を設けなくても良い。さらに、図１では透明蓋１５は視認面１２ｂと同形としているが、異なる形状であってもよく、視認用孔１３ａ，１３ｂを別々の部材で個別に封鎖するよう、分割して構成しても良い。   In addition, the transparent cover 15 should just be able to visually recognize the optical component 11 (optical element 11a) arrange | positioned at the adsorption | suction surface side in the state which sealed the visual recognition surface side of the holes 13a and 13b for visual recognition, for example, a glass plate, It is preferable to form with a transparent plastic plate. Further, when guide holes 16 a and 16 b are provided in the jig 10, it is preferable that the guide holes 16 a and 16 b are also formed in the transparent lid 15. The guide hole is not necessarily provided. Further, in FIG. 1, the transparent lid 15 has the same shape as the viewing surface 12b. However, the transparent lid 15 may have a different shape, and the viewing holes 13a and 13b may be divided so as to be individually sealed by separate members. good.

治具１０の製造に際しては、例えば、後述する光コネクタのフェルールを軸方向と直交する方向でカットすることにより形成することもできる。光コネクタのフェルールは、光学部品１１の光素子１１ａと対応する位置に光ファイバの挿着孔が形成され、光コネクタ間の接続を形成する結合ガイド孔等が形成されている。すなわち、治具の視認用孔１３ａ，１３ｂは、光ファイバの挿着孔をそのまま利用でき、ガイド孔１６ａと１６ｂは、コネクタ接続の結合ガイド孔を利用することができる。   In manufacturing the jig 10, for example, it can be formed by cutting a ferrule of an optical connector described later in a direction orthogonal to the axial direction. In the ferrule of the optical connector, an optical fiber insertion hole is formed at a position corresponding to the optical element 11a of the optical component 11, and a coupling guide hole or the like for forming a connection between the optical connectors is formed. That is, the jig viewing holes 13a and 13b can use optical fiber insertion holes as they are, and the guide holes 16a and 16b can use connector-connected coupling guide holes.

上述した治具１０を用いて光学部品１１を吸着保持し、実装基板に位置決めして実装する具体的な方法については後述するが、光学部品１１を治具１０の所定の位置に位置決めして吸着するには、視認用孔１３ａ，１３ｂが用いられる。すなわち、光学部品１１の両端に位置する光素子１１ａ’を視認用孔１３ａ，１３ｂと透明蓋１５を通して視認し、両端に位置する光素子１１ａ’と視認用孔１３ａ，１３ｂとが一致するように調心する。治具１０と光学部品１１との調心が行われた後、吸引用孔１４ａ，１４ｂを通じて真空引きすることにより、吸着面１２ａに光学部品１１を吸着保持させる。 A specific method for picking and holding the optical component 11 using the jig 10 described above and positioning and mounting the optical component 11 on the mounting substrate will be described later. However, the optical component 11 is positioned at a predetermined position of the jig 10 and sucked. For this purpose, the visual recognition holes 13a and 13b are used. That is, the optical elements 11a ′ positioned at both ends of the optical component 11 are viewed through the viewing holes 13a, 13b and the transparent lid 15, and the optical elements 11a ′ positioned at both ends are aligned with the viewing holes 13a, 13b. Align. After the jig 10 and the optical component 11 are aligned, the optical component 11 is sucked and held on the suction surface 12a by vacuuming through the suction holes 14a and 14b.

上記の治具１０によれば、光学部品１１に位置合わせ用の穴やマークがなくても、両端に位置する光素子を２つの視認用孔１３ａ，１３ｂを通して観察することにより、精度良く調心することができ、調心のための溝や突起を形成する加工を省略することが可能となる。また、調心に用いた視認用孔１３ａ，１３ｂは、吸引用孔１４ａ，１４ｂにも通じているので、光学部品１１の調心が行われた後、直ちに、光学部品１１を治具１０に吸着保持させることができ、視認用孔１３ａ，１３ｂを光学部品の調心と吸着保持の両方に効果的に用いることができる。   According to the jig 10 described above, even if there is no alignment hole or mark in the optical component 11, the optical elements positioned at both ends are observed through the two visual recognition holes 13a and 13b, thereby accurately aligning. Therefore, it is possible to omit the process of forming grooves and protrusions for alignment. Further, since the visual recognition holes 13a and 13b used for alignment also communicate with the suction holes 14a and 14b, the optical component 11 is immediately attached to the jig 10 after alignment of the optical component 11 is performed. The holes 13a and 13b for visual recognition can be effectively used for both alignment and suction holding of the optical component.

図２〜４は、上述した光学部品１１を吸着保持して実装基板に位置決めして実装する具体的な方法を説明する図である。図中、１８は吸引具、１９は実装基板、２０は配線導体、２１はレンズ部品、２２は光コネクタのフェルールを示し、その他の符号は、図１で用いたのと同じ符号を用いることにより説明を省略する。
まず、図２（Ａ）に示すように、光学部品１１の両端の光素子を視認用孔１３ａ，１３ｂを通じて、治具１０と光学部品１１との位置関係を調心した後、吸引具１８により吸引用孔１４ａ，１４ｂから吸引を行う。この吸引により光学部品１１は、治具１０の吸着面に吸着される。 2 to 4 are diagrams for explaining a specific method for mounting the above-described optical component 11 by suction and positioning on the mounting substrate. In the figure, 18 is a suction tool, 19 is a mounting board, 20 is a wiring conductor, 21 is a lens component, 22 is a ferrule of an optical connector, and the other reference numerals are the same as those used in FIG. Description is omitted.
First, as shown in FIG. 2A, after aligning the positional relationship between the jig 10 and the optical component 11 through the visual recognition holes 13a and 13b, the optical elements at both ends of the optical component 11 are aligned with the suction tool 18. Suction is performed from the suction holes 14a and 14b. By this suction, the optical component 11 is attracted to the suction surface of the jig 10.

次いで、図２（Ｂ）に示すように、治具１０に光学部品１１を吸着させた状態を保って、治具１０の両側に形成されたガイド孔１６ａ，１６ｂを、実装基板１９に設けたガイドピン１７ａ，１７ｂに一致させて嵌合させる。図３（Ａ）は、ガイド孔１６ａ，１６とガイドピン１７ａ，１７ｂとが嵌合された状態を示し、この状態とすることにより、治具１０が位置決めされて実装基板１９の所定位置に載置される。そして、治具１０に吸着保持されている光学部品１１の実装基板１９上における位置決めがなされ、接着材等により固定されて実装される。   Next, as shown in FIG. 2B, guide holes 16 a and 16 b formed on both sides of the jig 10 are provided in the mounting substrate 19 while keeping the optical component 11 attracted to the jig 10. The guide pins 17a and 17b are fitted and fitted. FIG. 3A shows a state in which the guide holes 16 a and 16 and the guide pins 17 a and 17 b are fitted, and in this state, the jig 10 is positioned and placed on a predetermined position of the mounting substrate 19. Placed. Then, the optical component 11 sucked and held by the jig 10 is positioned on the mounting board 19 and fixed and mounted by an adhesive or the like.

光学部品１１が治具１０の案内により、実装基板１９の所定の位置に位置決めされ、実装された後は、図３（Ｂ）に示すように、治具１０の吸引状態が解除され、治具１０は光学部品１１の吸着保持を解放して退避される。
なお、実装基板１９には、光学部品１１の光素子を電気的に接続するための配線導体２０が形成されていて、光学部品１１の実装時に導電バンプによる電気接続、または、光学部品の導電部にボンディングワイヤ等を用いて電気接続される。 After the optical component 11 is positioned at a predetermined position on the mounting substrate 19 by the guide of the jig 10 and mounted, the suction state of the jig 10 is released as shown in FIG. 10 is released by releasing the suction holding of the optical component 11.
A wiring conductor 20 for electrically connecting the optical elements of the optical component 11 is formed on the mounting substrate 19. When the optical component 11 is mounted, electrical connection by a conductive bump or a conductive portion of the optical component 11 is performed. Are electrically connected using a bonding wire or the like.

次いで、図４に示すように、反射ミラーを備えたレンズ部品２１を介して、光学部品１１と光コネクタのフェルール２２とを光学的に結合するように組み付けることができる。レンズ部品２１と光学部品１１とは、例えば、治具１０の位置決めに用いたガイドピン１７ａ，１７ｂを用いて、位置決めすることができる。また、レンズ部品２１とフェルール２２も、ガイドピンとガイド孔（図示されず）を用いて位置決めすることにより結合される。この結果、光学部品１１の光素子とフェルール２２の光ファイバとは、それぞれ光学的に光結合される。   Next, as shown in FIG. 4, the optical component 11 and the ferrule 22 of the optical connector can be assembled so as to be optically coupled via the lens component 21 having a reflection mirror. The lens component 21 and the optical component 11 can be positioned using, for example, guide pins 17 a and 17 b used for positioning the jig 10. The lens component 21 and the ferrule 22 are also coupled by positioning using a guide pin and a guide hole (not shown). As a result, the optical element 11 of the optical component 11 and the optical fiber of the ferrule 22 are optically optically coupled.

図５は、上述した光学部品１１を実装基板１９に実装する工程の一例を説明する図である。図中、１７はガイドピン、２３は作業台、２４はアームを示し、その他の符号は図１〜４で用いたのと同じ符号を用いることにより説明を省略する。
まず、ステップＳ１で、光学部品を実装する実装基板１９に使用する治具１０をガイドピン１７を用いて仮結合する。次いで、ステップＳ２で、実装基板１９に治具１０を保持した状態で作業台２３に移送し、ステップＳ３で、実装基板１９を作業台２３上に載せて固定する。 FIG. 5 is a diagram illustrating an example of a process for mounting the above-described optical component 11 on the mounting substrate 19. In the drawing, 17 is a guide pin, 23 is a work table, 24 is an arm, and the other reference numerals are the same as those used in FIGS.
First, in step S <b> 1, the jig 10 used for the mounting substrate 19 on which the optical component is mounted is temporarily coupled using the guide pins 17. Next, in step S2, the jig 10 is held on the mounting board 19 and transferred to the work table 23. In step S3, the mounting board 19 is placed on the work table 23 and fixed.

実装基板１９を作業台２３上に固定したら、ステップＳ４で、治具１０を上方に退避させるか、または、作業台２３側を下方に退避させる。次いで、ステップＳ５において、治具１０の下面側に光学部品１１がアーム２４により搬送され、治具１０と光学部品１１との調心（位置合わせ）が行われる。この調心が行われた後、ステップＳ６において、アーム２４を上方に移動して光学部品１１を治具１０に吸着保持させ、次いで、ステップＳ７で、アーム２４を退避させる。   When the mounting substrate 19 is fixed on the work table 23, the jig 10 is retreated upward or the work table 23 side is retreated downward in step S4. Next, in step S <b> 5, the optical component 11 is transported by the arm 24 to the lower surface side of the jig 10, and alignment (positioning) between the jig 10 and the optical component 11 is performed. After this alignment, in step S6, the arm 24 is moved upward to attract and hold the optical component 11 on the jig 10, and then in step S7, the arm 24 is retracted.

次のステップＳ８では、治具１０を作業台２３上の実装基板１９にガイドピン１７を用いて位置決めして載置し、吸着保持している光学部品１１を実装基板１９に接触させ、接着材等で固定する。この後、ステップＳ９で、治具１０は光学部品１１に対する吸着を解放し、ガイドピン１７との嵌合を外して退避させる。さらに、必要に応じてステップＳ１０において、レンズ部品２１が光学部品１１の上方にガイドピン１７を利用して位置決めされ、組み付けられる。そして、ステップＳ１１で、レンズ部品２１は光学部品１１と光結合されて実装基板１９に接着材等で固定される。   In the next step S8, the jig 10 is positioned and placed on the mounting board 19 on the work table 23 using the guide pins 17, the optical component 11 held by suction is brought into contact with the mounting board 19, and the adhesive is used. Fix with etc. Thereafter, in step S9, the jig 10 releases the suction to the optical component 11, and removes the fitting with the guide pin 17 and retracts it. Further, if necessary, in step S10, the lens component 21 is positioned and assembled using the guide pin 17 above the optical component 11.
