Description

  The present invention relates to an optical wiring manufacturing method and apparatus capable of efficiently transmitting a required optical signal to a required place in a signal processing portion where an optical signal or an optical signal and an electrical signal are mixed.

There are the following three methods for producing a conventional optical wiring.
The first method is a method in which a glass film or a polymer film having a good light transmittance is formed on a substrate and is manufactured by a manufacturing method similar to that for forming a circuit pattern used for manufacturing an LSI. It is prepared by applying a photosensitive agent on the surface of a glass film or polymer film, exposing it using a mask having an optical wiring pattern, and then removing unnecessary parts by etching. However, the above process is repeated twice. This technology has the advantages of being able to write complex patterns and making optical elements together, but on the other hand, it requires large-scale semiconductor equipment, cannot make large-scale devices, and cannot make wiring that connects substrates. There are disadvantages.

  The second method uses an optical fiber for wiring. Although this conventional method is simple, it has the disadvantage that it is unstable and takes up space because the wires are simply bundled and fixed with wires. Further, when the number of optical fibers to be bundled is increased, it becomes difficult to manage how the optical fibers are connected.

The third method is a method in which an optical fiber is sandwiched and fixed by a polymer sheet. Since the wiring can be patterned, management can be easily performed even if the number of optical fibers is increased. In addition, there is an advantage that a large apparatus is not required. However, since the structure is sandwiched between polymer sheets, it is impossible to fabricate an optical wiring on a substrate or on a plate connecting the substrates.

A large-scale semiconductor facility, which is a disadvantage of the manufacturing method similar to the circuit pattern formation used for LSI manufacturing, is necessary, large-sized devices cannot be made, and wiring that connects substrates to each other cannot be made To solve the problem of using unstable and space, which is a disadvantage of the method of using optical fiber for wiring, and managing how the optical fiber is connected becomes difficult as the number of optical fibers increases. It is a problem to solve the problem that optical wiring cannot be formed on a substrate or a plate connecting the substrate and the substrate, which is a disadvantage of the method of sandwiching and fixing with a polymer sheet.
That is, the object of the present invention is not to require expensive equipment such as an LSI manufacturing apparatus, and since an LSI manufacturing apparatus is not used, large optical wiring and wiring connecting the substrate and the substrate are not required. In addition, since the optical fiber is fixed with an adhesive, it is stable and space-saving, and since the optical fiber is not fixed by sandwiching it with a polymer sheet, the substrate and backplane, and the wiring that connects the substrate and the substrate are manufactured. An object of the present invention is to provide an optical fiber wiring method and apparatus that can be used.

  In order to solve the above-mentioned problem, the optical fiber wiring method according to the first aspect of the present invention is an optical fiber transport mechanism on the substrate, which is any one of the forward / backward movement, the left / right movement, the vertical movement, and the rotation.

The second invention is characterized in that a mechanism for feeding the optical fiber onto the substrate is fixed, and a stage on which the substrate is fixed is provided. An optical wiring is formed on the substrate by moving.

  According to a third aspect of the present invention, an optical fiber is moved to a predetermined wiring location by moving or moving back and forth, moving left and right, moving in the vertical direction, rotating, or a combination thereof by an optical fiber transport mechanism on a substrate. Then, the optical fiber is tracked and an adhesive is discharged to bond the substrate and the optical fiber, thereby bonding and solidifying the substrate and the optical fiber to form an optical wiring on the substrate. The fourth aspect of the invention is characterized in that a mechanism for sending an optical fiber onto a substrate is fixed, and an optical wiring is formed on the substrate by moving a stage to which the substrate is fixed.

  A fifth invention is characterized in that, in any one of the first to fourth inventions, the optical fiber is an optical fiber made of a polymer, and the sixth invention is any one of the first to fifth inventions.

A transport device for feeding onto the substrate, an adhesive discharge device for discharging the adhesive and applying the adhesive to the optical fiber immediately before the optical fiber comes into contact with the substrate or just before the optical fiber contacts the substrate, and the substrate The eighth invention fixes a mechanism for sending an optical fiber onto a substrate, and the stage on which the substrate is fixed moves up and down, left and right, and moves in the vertical direction. It is characterized in that any one of rotation movement or compound movement is possible, and the ninth invention is capable of any one of movement in the front and rear, movement in the left and right, movement in the vertical direction, rotation, or compound movement. Light phi Conveying device for sending the bar onto the substrate, an adhesive discharging device for tracking the optical fiber sent onto the substrate and discharging the adhesive to bond the substrate and the optical fiber, and a stage for fixing the substrate According to a tenth aspect of the present invention, there is provided a mechanism for feeding an optical fiber onto a substrate, and a stage on which the substrate is fixed is moved up and down, left and right, moved in the vertical direction, rotated, or combined. The eleventh invention uses an adhesive that cures when irradiated with ultraviolet rays as the adhesive, and cures the adhesive that is wired on the substrate and holds the optical fiber. An ultraviolet irradiation unit for irradiating ultraviolet rays for the purpose is provided.

  According to the optical fiber wiring method of the present invention, large-scale optical wiring and a substrate and a backplane, and a substrate and a substrate are connected because an expensive facility such as an LSI manufacturing device is not required and an LSI manufacturing device is not used. Wiring is possible, and the optical fiber is fixed with an adhesive, so it is stable and space-saving. In addition, the optical fiber is not sandwiched and fixed with a polymer sheet, so the wiring that connects the substrate and backplane, and the substrate and substrate Can be produced.

A preferred embodiment of the present invention will be described in particular regarding a mechanism for feeding an optical fiber onto a substrate.
First, the configuration of the entire apparatus will be described with reference to FIG.
This apparatus is moved in the X direction by the main body 1, the two struts 2 and 2 disposed on both sides of the main body, the X direction moving means 3 supported by the two struts, and the X direction moving means 3. A moving block 4, a shaft 5 extending downward from the lower end of the moving block 4, and a head portion 6 fixed to the shaft 5, and a Y-direction moving means is arranged inside the main body 1. The work table 7 is moved in the Y direction by the Y direction moving means. A substrate for wiring the fiber is placed on the work table 7.
In addition, a Z-direction moving means and a θ-direction moving means are disposed inside the moving block 4 so that the shaft can be moved in the Z direction (up and down direction), and the shaft is the length of the shaft. The direction can be rotated (θ direction) about the rotation axis.
Accordingly, the head portion 6 fixed to the shaft 5 can be moved in the vertical direction, and the head portion 6 can be rotated.
Furthermore, since the moving block 4 is moved by the X direction moving means 3, the head unit 6 can also be moved in the X direction by moving the moving block 4 in the X direction.
With this configuration, the work table 7 and the head unit 6 can be moved relative to each other in the front-rear, left-right, and up-down directions, and the head unit 6 is rotated with respect to the surface of the work table 7. It can be moved.

Next, the configuration of the head unit will be described with reference to FIG. 2 (see FIGS. 8 and 9).
The head portion is roughly composed of a bobbin 9 that winds and stores the fiber 8, a roller that feeds the fiber 8, a blade 10 that cuts the fiber 8, and a discharge mechanism that supplies an adhesive to the fiber 8. 11 is provided.
Specifically, a head base is fixed to the shaft 5.
A bobbin 9 in which the optical fiber 8 is wound and accommodated is detachably disposed on the head base, and the optical fiber 8 is sent out from the guide C to the outside via the guide A and the guide B. A roller A and a roller B are disposed between the guide A and the guide B, and the optical fiber is sandwiched between the roller A and the roller B. The fiber 8 can be moved in the direction in which the fiber 8 is accommodated in the bobbin 9 by the operation of rotating from the guide C and rotating in the direction opposite to the feeding direction of the fiber 8 of the roller A.
Here, the motor A is communicated with a rotation driving means (not shown), and the roller A is configured to rotate in conjunction with the rotation of the motor A. The roller B is in contact with the roller A and rotates in the direction opposite to the rotation direction of the roller A by the rotation operation of the roller A.
Further, a fiber cutting means 16 is arranged between the guide B and the guide C. Here, the optical fiber between the guide B and the guide C is between the blade connected to the actuator and the blade receiver, and the cutting edge of the blade 10 moves toward the optical fiber 8 by the advance movement of the actuator. The optical fiber 8 is cut by the action that occurs between the blade edge and the blade receiver.
The head base includes a liquid ejection mechanism 11.
Here, the liquid ejection mechanism 11 communicates with the nozzle 12 having an ejection port for ejecting liquid, the syringe 13 communicating with the nozzle and storing liquid material, and the syringe, and transmits pressure to the liquid in the syringe. And an adapter tube 14 to be used.
The adapter tube 14 communicates with a dispenser that supplies a desired pressure for a desired time.
The roller is connected to the motor. The roller feeds the fiber as the motor rotates. Since the bobbin 9 is configured to rotate smoothly, unnecessary tension is not applied to the fiber even when the roller feeds the fiber.
The roller A is preferably capable of feeding an appropriate amount of fiber from the guide C to the outside by controlling the rotation amount according to the relative moving speed of the head portion and the work table.

In order to allow the mechanism 11 to move back and forth, to the left and right, to move in the vertical direction, to rotate, or to move in combination, the mechanism, that is, the head unit 6 is required to move the workpiece (workpiece). The head of the robot in which the head unit 6 and the substrate move relatively to move relative to the table 7) in the front-rear, left-right, and vertical directions and to rotate relative to the work surface. When this mechanism is mounted on the door, combined movement becomes possible.
When the mechanism is fixed, the mechanism, that is, the head portion is fixed to the shaft.
The method of fixing to the shaft may be fixed by a generally known method such as screw tightening or split tightening.

For the stage for fixing the substrate, the optical fiber is laid in a desired pattern on the substrate by relatively moving the stage and the head unit, so the positional relationship between the stage and the substrate on the stage is constant. There must be. That is, the substrate should not be displaced on the stage.
In order to prevent this, it is necessary to fix the work on the substrate. For this, the substrate may be appropriately fixed by a conventionally known method such as fixing by vacuum pressure adsorption. In order to use the present invention, no special substrate fixing method is required.
In the present embodiment, the stage is fixed in the Y direction and the head portion is in the X direction. The stage for fixing the substrate can be moved up and down, left and right, moved in the vertical direction, rotated, or combined. A desired shape is drawn by moving in the axial direction, the Z-axis direction, and the direction of rotation about the Z-axis, respectively.
However, since wiring is performed by relatively moving the substrate and the head unit, the head unit is fixed, and the table is moved or combined in the X direction, Y direction, Z direction, and rotation direction, so that the light It is possible to route the fiber, although not shown.

The liquid discharge mechanism 11 corresponds to the means for discharging the adhesive immediately before the optical fiber comes into contact with the substrate or before the optical fiber contacts the substrate or by tracking the optical fiber. That is, the nozzle, the syringe for storing the liquid material, and the dispenser (pressure device for supplying regulated air) are the basic components, and the air pulse is sent to the syringe 13 by means such as the dispenser. It is given to the liquid, and the liquid is discharged from the nozzle tip.
The nozzle 12 and the syringe 13 are detachably fixed to the head base.
As described above, the head unit 6 moves in the x-axis direction, moves in the z direction, and rotates (in the θ direction).
It is preferable to pressurize and discharge the liquid material in the syringe in synchronization with the operation of the robot.
As described above, the head portion rotates in the θ direction immediately before the optical fiber comes into contact with the substrate or the positional relationship between the means for tracking the optical fiber and discharging the adhesive and the mechanism for feeding the optical fiber onto the substrate. Therefore, the head portion during fiber wiring controls the angle of the head by rotating the shaft so that the nozzle is behind the fiber with respect to the traveling direction.
It is preferable to synchronize the rotation amount of the feed mechanism and the robot speed. That is, it is preferable to send a fiber having the same length as the movement amount of the robot (head), and it is preferable that the moving speed and the fiber feeding speed are the same.

An optical fiber made of a polymer is a plastic fiber. The core part through which the optical signal propagates and the surrounding cladding part are all made of plastic. Compared to quartz-based optical fibers, they are cheaper and have a feature that they are strong against bending and are not easily broken. Further, they have features such as low cost, ease of handling, and safety.
The adhesive can be selected and used depending on the application, such as thermosetting and ultraviolet curable. Regarding the solidification (curing) of the adhesive, the used adhesive is cured. Heat is applied to the adhesive if it is a thermosetting adhesive, and ultraviolet light is applied to the adhesive if it is an ultraviolet curable resin. For example, it can be cured by placing a heater on the table and controlling the temperature of the substrate after fiber wiring, or curing from the side of fiber wiring by arranging ultraviolet irradiation means on the head part. Is also possible. Thus, it is also possible to harden by devising this apparatus. After fiber wiring, it may be appropriately cured by other means different from the present apparatus.

  When UV adhesive is used for curing by irradiating with ultraviolet rays, the adhesive is cured by irradiating the applied adhesive with ultraviolet rays, and the optical fiber is fixed on the substrate. Is done. The positional relationship between the means for tracking the optical fiber and discharging the adhesive and the ultraviolet irradiation means (ultraviolet irradiation section for irradiating ultraviolet rays) is basically irradiated after drawing. The head is rotated to achieve this positional relationship.

For optical wiring, after placing the optical fiber at the predetermined wiring location by the optical fiber transport mechanism with respect to the substrate or the substrate and the backplane or the substrate and the substrate, the optical fiber is not displaced from the predetermined wiring location. And the optical fiber is bonded and solidified on the substrate or the back plane to produce an optical wiring.
The backplane is a socket for connecting a rotating board or a receiving circuit board or device having a slot. It is mainly located on the back of the housing, and can be connected to connectors, cables, and other devices. The backplane may be abbreviated as “B / P”.

FIG. 3 is a diagram for explaining the first embodiment, showing an outline of the optical fiber wiring device of the present invention and a wiring substrate formed by using the device, and a mechanism for feeding the optical fiber onto the substrate. It moves relative to the substrate.
The optical fiber wiring device includes a nozzle 15 that sends out the optical fiber 8, a device 16 that cuts the optical fiber 8 provided in the vicinity of the tip of the delivery port of the nozzle 15, a nozzle 12 that discharges the adhesive, and an adhesive discharge. , A device 18 for controlling the delivery of the optical fiber, a control device 25 for controlling both the delivery of the optical fiber and the discharge of the adhesive, a device 17 for controlling the discharge of the adhesive, and the control device 25. Are connected to each other, a cord 27 for connecting the optical fiber discharge device 18 and the control device 25, and an arm 28 for moving a mechanism for feeding the optical fiber 8 onto the substrate.
In addition, the wiring board formed by the above device includes a substrate 19, an optical fiber 20 wired and bonded on the substrate 19, a backboard 21 connecting the substrate and the substrate or another device, and an electrical signal. Are formed by a semiconductor chip 22 for processing, electrical wiring 23 for connecting the chips on the substrate, and a semiconductor chip 24 for performing photoelectric conversion.

  FIG. 4 is a view showing a method of bonding an optical fiber with an adhesive, in which 29 is an adhesive. FIG. 5 is a diagram for explaining the optical fiber 20 bonded to the substrate with an adhesive 29 in more detail, in which 30 is a cladding portion of the optical fiber 20 and 31 is a core portion of the optical fiber 20.

  In order to form the optical wiring by the optical fiber, in addition to the program for the normal robot that moves the arm 28, the program that moves in cooperation with the control device 25 that controls both the delivery of the optical fiber and the discharge of the adhesive is written. The arm 28 and the device 17 for controlling the ejection of the adhesive and the device 18 for controlling the ejection of the optical fiber are driven simultaneously. After the optical fiber discharged from the nozzle 15 reaches the substrate 19 or the backboard 21, an adhesive is discharged from the nozzle 12 that tracks the optical fiber.

  There are four ways to discharge the adhesive as shown in FIG. A method of covering and bonding at a point as in (1), a method of covering and bonding at a specific length as in (2), a method of covering by mixing the above methods as in (3), For example, a method of covering all optical fibers as in (4). These bonding methods are selected depending on the shape of the optical fiber wiring. For example, in the case of wiring in a straight line, the force to be shifted to the optical fiber is not applied, so that the point (1) can be adhered, but the force to be shifted is applied to the curved shape, and the relatively long coating of (2) is applied. A bonding method that holds the wiring shape by bonding is suitable.

By selecting the amount and viscosity of the adhesive 30, the shape in which the optical fiber adheres to the substrate or backboard can be selected. High viscosity and increasing the amount can thick covered adhesively bonded as in (1) in FIG. This bonding method is effective for protecting an optical fiber. If the amount is low and the amount is small, the adhesive can be hardly seen on the upper surface of the optical fiber as shown in (2). This bonding method is suitable for high-density wiring of optical fibers.
With this method and apparatus, the optical signal can be easily connected between the substrate and the substrate through the connection of the optical signal between the substrate and the backboard, and the connection between the substrate and the backboard.

FIG. 6 is a diagram for explaining the second embodiment and shows an outline of the optical fiber wiring device of the present invention. The substrate moves back and forth with respect to the mechanism that sends the optical fiber onto the substrate, and the mechanism that sends the optical fiber onto the substrate moves left and right with respect to the substrate.
In the figure, 32 is a tube through which an adhesive passes, 33 is a stage for moving back and forth, 34 is a drive unit for the stage for moving back and forth, 35 is a rail for moving back and forth, and 36 is a mechanism for moving the optical fiber onto the substrate to move left and right. A rail 37 is a drive unit in which a mechanism for sending the optical fiber onto the substrate moves left and right, and 38 is a cord for connecting the control unit 25 for controlling these drive units.

In order to form the optical wiring by the optical fiber, the control devices 17 and 18 for controlling the ejection of the optical fiber and the ejection of the adhesive, the drive unit 34 of the back and forth moving stage, and the mechanism for sending the optical fiber onto the substrate move to the left and right A program that moves in conjunction with the driving unit 37 is written to the control device 25.
As a result, an optical wiring using an optical fiber fixed with an adhesive could be produced on the substrate. The propagation loss of light on the optical wiring manufactured in this way is equivalent to the optical fiber used. Wiring crossing transmission lines, which is impossible with an optical circuit using an LSI process, is also possible. In addition, the time required for manufacturing the optical circuit has been greatly shortened, the cost required for manufacturing has been reduced, and the economy has been improved.

  In Example 1, when an optical fiber made of a polymer is used as the optical fiber, since the dimensions of the core portion 31 and the cladding portion 30 of the optical fiber are large, the accuracy of the pattern, the connection between the optical fiber and other optical components, and The accuracy of the connection between the optical fiber and the optical fiber has become loose, making it easier to fabricate the optical wiring. Further, since the optical fiber is soft and the refractive index difference between the core portion 31 and the clad portion 30 can be increased, the radius of curvature of the circuit curve can be reduced and the optical wiring can be reduced. Furthermore, the wettability and adhesion between the optical fiber and the adhesive are good, and this characteristic also facilitates the production of optical wiring. In addition, when the optical fiber is cut after the optical wiring is formed, the result is simple because it is soft.

FIG. 7 is a diagram for explaining the fourth embodiment. The optical fiber 20 bonded to the substrate 19 or the backboard 21 by the adhesive 29 that is cured by ultraviolet irradiation is immediately irradiated with ultraviolet rays by the ultraviolet irradiation unit 39. The optical wiring is cured in a short time on the substrate 19 or the backboard 21, and is basically the same as in the other embodiments, but the adhesive 29 is an ultraviolet curable adhesive. The difference is that an ultraviolet irradiation unit 39 is provided behind the nozzle 12 that discharges the adhesive in the working direction.
In the figure, reference numeral 40 denotes a cord for supplying power to and controlling the ultraviolet irradiation unit 39.

This will be described with reference to FIG. In the apparatus shown in FIG. 2, the syringe 13 and the nozzle 12 illustrated here are further inclined with respect to the fiber 8. By doing so, the tip of the nozzle 12 that was directed to the fiber on the substrate at the position of FIG. 2 is positioned to face the fiber 8 just before contacting the substrate 19.
Therefore, as shown in FIG. 8, it is possible to apply the adhesive to the fiber 8 delivered from the guide C and immediately before contacting the substrate 19.
In addition, by making the syringe 13 and the nozzle 12 have an angle with respect to the optical fiber 8, the method of FIG. 2 in which an adhesive is applied to the fiber after the substrate wiring, or after the fiber 8 just before the substrate wiring is applied An apparatus can also be constructed that can also allow the method of FIG. 8 to be placed on a substrate. Either wiring is possible with one unit.

Further, in the apparatus shown in FIG. 2, the adhesive is applied to the fiber 8 just before contacting the substrate 19 by the application method shown in FIG. 8, that is, by attaching the curved nozzle 12 to the syringe 13. It is possible to apply and apply the adhesive-attached optical fiber on the substrate. This is shown in FIG.
By simply replacing the nozzle, this also allows the method of FIG. 2 to apply the adhesive to the fiber after the substrate wiring, or the method of FIG. 8 that can be placed on the substrate after being applied to the fiber just before the substrate wiring. It can be.

  By the optical wiring manufacturing method and apparatus capable of efficiently transmitting a required optical signal to a required place according to the present invention, various methods having a signal processing portion in which an optical signal or an optical signal and an electric signal are mixed are provided. Applicable to the field. The scope of application of the present invention is wide, and it can be any machine as long as it uses electrical signals as well as parts of home appliances that handle optical signals and electrical signals such as MD players and DVD players. There is a possibility of being used for manufacturing parts such as airplanes.
