  Therefore, even if the next rear single plate is advanced by the single plate moving and conveying device, the front single plate is not crumpled between the tape application region and the single plate moving and conveying device. The distance between the rear end portion and the front end portion of the next rear single plate can be advanced to a good state, and a connection tape can be attached and connected.

  Embodiments of the present invention will be described below with reference to the drawings.

  The printed wiring board (printed circuit board) according to this embodiment is provided with a thin conductive film (for example, a conductive film formed of copper foil) in advance on both the front and back surfaces of a thin plate-like member, It is manufactured by processing a conductive film. The thin plate-like member (material) is, for example, a sheet-like copper-clad laminate (usually referred to as “CCL”) having flexibility, and a conductive film is in close contact with both sides of a polyimide base film. Is formed.

  Here, a method for manufacturing the printed wiring board will be schematically described.

  Referring to FIG. 6, first, a long sheet-like CCL having a predetermined width is cut into a predetermined length by a cutting line extending in the width direction to form a single plate. The predetermined width of the CCL is usually 250 to 500 mm (step S1).

  After the plurality of single plates (about 20) are overlaid so that their end faces coincide with each other, through holes are formed in the plurality of single plates almost simultaneously using a punch or a drill. This through hole is a hole for connecting the circuits on both sides. Thus, the working efficiency is improved by punching a plurality of single plates together (step S2).

  Next, each single plate having the through holes is subjected to through-hole plating so that the circuits on both sides are electrically connected (step S3).

  Next, a single plate connecting step of connecting the single plates subjected to the through-hole plating to each other is performed. That is, the ends of the single plates are arranged close to each other (in contact with or slightly apart from each other) so as not to overlap each other in the thickness direction. The end portions of the adjacent single plates are pasted with a connecting tape having a predetermined width so as to cover the adjacent end surface portions from one surface in the thickness direction of the single plates. Then, they are connected to each other and formed long, and are wound, for example, on a reel (bobbin) in a roll shape (step S4).

  Next, a circuit forming process for forming circuits on both surfaces of each single plate is performed. Each single plate formed long and wound in a roll shape as described above is fed into the processing apparatus while being fed out from the roll, and the printed wiring board after being processed into each single plate is taken up by another roll. A roll-to-roll (RR) system is adopted. At this time, when the roll-shaped single plate is sent to another roll, thin circuits are formed on both surfaces of each single plate. That is, a printed circuit is formed through processes such as surface conditioning, dry film lamination, exposure, development, etching, and circuit polishing that clean the surface of the conductive film of each single plate.

  More specifically, first, a surface-conditioning process for removing an oil film and fine dust is performed by removing the oxide film on the surface of the thin conductive film provided on both surfaces (front and back surfaces) of the single plate. .

  A dry film is affixed to the surface of the conductive film subjected to the surface conditioning treatment, and exposure is performed in a state where masks for forming circuits on both surfaces of the single plate are placed on the dry film.

  The pattern substrate is removed and development processing is performed, and the circuit configuration of the pattern substrate is transferred to the dry film.

  Subsequently, a part of the conductive film is removed by etching, and circuits having the same form as the circuit of the pattern substrate are formed on both surfaces of the single plate. Thereafter, the dry film remaining on both surfaces of the substrate is removed.

  As described above, since a plurality of single plates are overlapped with each other to form a through hole, a through hole for through-hole plating can be efficiently formed. Furthermore, after connecting each single plate with through-hole plating and winding it into a roll, when each roll-shaped single plate is fed out and sent to another roll, it is attached to both sides of each single plate. Since the circuit is formed, the circuit can be efficiently formed almost continuously (step S5).

  Subsequently, each of the connected single plates is separated (step S6). After this separation, a thin coverlay is attached to both surfaces of each single plate, and then die cutting is performed (step S7). A board is manufactured.

  As described above, the manufactured printed wiring board has circuits on both sides and has through holes for electrically connecting the circuits on both sides to each other. More efficiently.

  In addition, according to the printed wiring board manufacturing method described above, since the connecting tape is used to connect the single boards, the influence on the single boards is reduced (for example, the single board is damaged at the connection site). In other words, the single plates can be connected quickly and easily, and the connected single plates can be easily separated.

  Next, the single plate connecting device 1 in the method for manufacturing a printed circuit board will be described with reference to the drawings. This single plate connecting device 1 is used in the single plate connecting step of step S4 described above.

  Referring to FIG. 1, a veneer connecting apparatus 1 is a thin veneer 3 (for example, a printed wiring board) having a predetermined width and a predetermined length and having a rectangular shape and having flexibility. It is a device for connecting materials.

It can be moved up and down.

  More specifically, a connecting tape 5 having a predetermined width is wound around a reel and stored in a frame 13 which is a main body of the tape applicator 11. 3A and 3B are fed out in a direction substantially coinciding with the abutting portions of 3A and 3B, and the leading end side of the connecting tape 5 protruding downward from the lower surface of the frame 13 is pressed against the bonding table 9 from above by a pressing roller provided in the frame 13. It is a configuration. Note that an adhesive layer is provided on the lower surface side of the drawn connection tape 5.

  Further, when the frame 13 travels and the connecting tape 5 is stretched in the abutting direction of the end portions 3AR and 3BF of the single plates 3A and 3B and pasted so as to cover the end portions 3AR and 3BF, the connection tape 5 is attached. In this configuration, the tape 5 is cut by a tape cutting unit made of a cutter or the like provided in the frame 13.

  In addition, a single plate fixed transport device 15 for moving the front single plate 3A to the front side in the transport direction is provided on the front side in the transport direction with respect to the tape application region 7.

  This single plate fixing and conveying device 15 is unidirectional (in the direction of the arrows shown in FIGS. 1 and 2) in the direction of traveling through the front single plate 3A while vacuum-adsorbing one surface in the thickness direction of the front single plate 3A. By pulling and transporting in the transport direction), the front single plate 3A and the next rear single plate 3B connected to the front single plate 3A are transported.

  The single plate fixed transport device 15 will be described in detail. The single plate fixed transport device 15 is constituted by a belt conveyor 17 in this embodiment, and the belt 19 that rotates in an endless ring of the belt conveyor 17 has a front single unit. A plurality of rows of through holes 21 arranged in the conveying direction of the plate 3A are provided. Further, a flat guide member 23 is provided on the inner side of the belt 19 traveling on the upper side. The guide member 23 is provided with a plurality of rows of a plurality of grooves (not shown) formed to extend in the transport direction at positions corresponding to the through holes 21 of the belt 19.

  The groove-formed surface of the guide member 23 is close to or in contact with the inner surface of the belt 19, and the surface of the belt 19 opposite to the guide member 23 is the groove of the guide member 23 and the belt 19. The front single plate 3 </ b> A on the upper surface of the belt 19 can be vacuum-sucked through each through hole 21.

  The single plate fixed conveying device 15 is configured so that the belt 19 can be rotationally driven by a driving device such as a servo motor and stopped at an accurate position, and the driving device is connected to a control device (not shown). .

  Further, after being connected by the tape applicator 11 on the front side (right side in FIGS. 1 and 2) in the transport direction with respect to the single plate fixed transport device 15, the single plate fixed transport device 15 transports the single plate fixed transport device 15. A single plate take-up device 27 is provided for winding the connected single plates 3 on a reel 25 (bobbin). The reel 25 is rotatably provided with respect to the base (not shown), and is driven to rotate to wind up the plurality of connected single plates 3 by an actuator such as an electric motor (not shown). is there.

  Further, in the tape affixing region 7, the front end 3BF of the next rear veneer 3B hangs down at the rear part in the transport direction (left part in FIGS. 1 and 2), that is, at the rear part of the bonding table 9. A veneer front end portion placement area 29 is provided in which a portion is placed at the tape application height position PL of the bonding table 9.

  3A and 3B, the rear end portion of the veneer front end placement area 29 of the laminating table 9 has a comb-shaped first shape in this embodiment. A comb tooth portion 31 is provided. The first comb tooth portion 31 is provided with, for example, a sensor cutout window 35 as a position detection device cutout portion for providing, for example, an end position sensor 33 as an end position detection device, which will be described later. Yes.

  The position detection device notch is not limited to the sensor notch window 35, but may be a so-called mere notch using a part of the first comb tooth portion 31, for example. The sensor notch window 35 is desirable in that both ends in the width direction of the front end portion 3BF of the rear single plate 3B are placed on the first comb tooth portion 31.

  The reason is that the end position sensor 33 is preferably provided at a lower position where both ends in the width direction of the rear single plate 3B pass, so that the notch for the position detection device is merely a notch. When both ends in the width direction of the front end portion 3BF of the rear single plate 3B are hanging down in the width direction, when the rear single plate 3B moves forward, the above-described hanging portion is cut off. A situation occurs in which the front end of the notch collides. However, such a situation can be prevented with the sensor cutout window 35 as described above.

  The position of the sensor cutout window 35 is located on the front side of the position of the front end portion 3BF of the rear single plate 3B placed in the single plate front end placement region 29.

  Moreover, it is desirable that the comb-teeth shape of the first comb-teeth portion 31 is disposed so that both ends in the width direction of the front end portion 3BF of the next rear single plate 3B can be placed. The reason for this is that even if both ends in the width direction of the front end portion 3BF of the rear single plate 3B hang down in the width direction, the first comb tooth portion 31 inevitably corrects, so the rear single plate 3B It is because it can move forward without any trouble.

  Further, the rear end of the front single plate 3A is disposed in the tape application region 7 in the rear part in the transport direction (left part in FIGS. 1 and 2), in this embodiment, in the sensor cutout window 35. For example, an end position sensor 33 is provided as an end position detecting device for detecting the position of the portion 3AR or the position of the front end 3BF of the next rear single plate 3B. As the end position sensor 33, a combination of a reflection mirror and a reflection type photoelectric sensor, a transmission type photoelectric sensor, or another sensor is used.

  As shown in FIG. 1, the end position sensor 33 of this embodiment is disposed below the vicinity of the position where both side ends of the single plate 3 pass in the width direction orthogonal to the transport direction. Yes. In this embodiment, four end position sensors 33 are arranged in the width direction, and the two outer end position sensors 33 detect both side ends of the single plate 3 having a width of 500 mm. The two end position sensors 33 detect both side ends of the single plate 3 having a width of 250 mm.

  The end position sensor 33 is illustrated so as to send detection data that detects the position of the rear end 3AR of the front single plate 3A or the position of the front end 3BF of the next rear single plate 3B. Not connected to the control device.

  The end position sensor 33 does not detect a spot-like range, but has a light beam shape of a rectangular shape of, for example, 20 mm × 2.5 mm, and the light beam shape is processed into a single plate 3. The long side has a length twice or more as long as the hole, and the long side is arranged in parallel to the end portion of the single plate 3 to be detected.

Combine. When connecting the single plates 3A and 3B to each other with the tape applying device 11, the movable table 37 vacuum-sucks the next rear single plate 3B, and the single plate fixed conveying device 15 The single plate 3A is configured to be vacuum-sucked.

  Further, when the rear single plate 3B connected together with the front single plate 3A is transported by the single plate fixed transport device 15 after the single plates 3A and 3B are connected, the protrusion 41 is the upper surface of the movable table 37. It is configured to be immersed further downward and air floated on the upper surface of the movable table 37.

  Next, operation | movement of said single-plate connection apparatus 1 is demonstrated.

  As the single plate connecting step of the single plate connecting device 1, when the front single plate 3A is transported forward in the transport direction by the belt 19 of the single plate fixed transport device 15, reference numeral 2 in FIG. 1 and FIG. As indicated by the dashed line, the position of the rear end 3AR in the direction in which the front veneer 3A travels is detected by the end position sensor 33, and the detected data is sent to the control device. The control device calculates based on the position data of the rear end portion 3AR of the front single plate 3A, and the single plate so that the rear end portion 3AR of the front single plate 3A stops at a predetermined position in the tape application region 7. A command is given to the fixed conveyance device 15.

  When the single veneer 3A on the front side is conveyed forward in the conveying direction as indicated by an arrow in FIGS. 1 and 4A and passes through the end position sensor 33, it is shown in FIG. 5A. As shown in FIG. 5, the distance D between the end position sensor 33 and the bonding center position TCL is conveyed, and the rear end 3AR of the front veneer 3A is a predetermined position in the tape applying region 7, that is, FIG. ) And stop at the bonding center position TCL as shown in FIG.

  In FIGS. 5A and 5B, the bonding table 9 is elongated to the front side, and a vacuum suction device for vacuum-sucking the front veneer 3A to the stretched portion when stopped. The heater 9 </ b> A is embedded in the bonding table 9 so as to be positioned in the tape application region 7, but the vacuum suction device and the heater may not be provided.

  The front single plate 3 </ b> A is vacuum-sucked on the upper surface of the belt 19 of the single plate fixed conveyance device 15. When the belt 19 is rotationally driven, the single plate winding device 27 is also rotationally driven in synchronism, and the plurality of connected single plates 3 are wound on the reel 25 on the front side.

  Next, the next rear single plate 3B indicated by a two-dot chain line in FIG. 4A protrudes from the upper surface of the movable table 37 into a positioning reference hole 3H provided in the rear single plate 3B. By inserting the protrusion 41, the positioning is performed on the upper surface of the movable table 37 as shown in FIGS. 1 and 4B. The next rear single plate 3 </ b> B is vacuum-sucked on the upper surface of the movable table 37.

  The portion of the rear single plate 3B that protrudes forward from the front end of the second comb-tooth portion 39 of the movable table 37 is its own weight, particularly when the rear single plate 3B is thin without plating. In some cases, a sagging state may occur due to the deformation, and this sagging state will be described below.

  3A and 5A, the depth of the rear end of the first comb tooth portion 31 of the bonding table 9 and the second comb tooth portion 39 of the movable table 37 is determined. The distance between the rear end surface is A, the distance between the front end surface of the depth of the first comb tooth portion 31 of the bonding table 9 and the front end of the second comb tooth portion 39 of the movable table 37 is B, and the bonding table 9 The distance between the front end portion 3BF of the rear single plate 3B placed in the single plate front end portion placement region 29 and the pasting center position TCL is C, and the end position sensor 33 and the pasting center position TCL The distance between the rear end of the first comb tooth portion 31 of the bonding table 9 and the front end of the second comb tooth portion 39 of the movable table 37 is E, and the first comb tooth portion 31 and the second When the depths of the comb teeth 39 are substantially the same dimension F and the distances A and B are substantially the same dimension (A≈B), A (≒ B) is a distance C greater dimensions. In addition, the portion of the rear single plate 3B that protrudes forward from the front end of the second comb tooth portion 39 of the movable table 37 has a size larger than the distance E.

  Accordingly, when the rear single plate 3B is positioned on the upper surface of the movable table 37, as shown in FIGS. 3 (A), 4 (B) and 5 (A), the rear single plate 3B. The front end 3BF of 3B is necessarily placed on the single plate front end placement area 29 of the bonding table 9. As a result, the sagging state of the front end 3BF of the rear veneer 3B is inevitably corrected and positioned at the tape application height position PL of the bonding table 9.

  Next, when the operator turns on the switch for operating the movable table 37, the movable table 37 is transported to the next rear single plate 3B as indicated by the arrows in FIGS. 1 and 4B. The position of the front end 3BF in the direction in which the next rear single plate 3B advances is detected by the end position sensor 33, and the detected data is sent to the control device.

  In the control device, the data of the position of the front end 3BF of the rear veneer 3B and the rear end 3AR of the front veneer 3A already stopped at a predetermined position of the bonding table 9 in the tape application area 7 Based on the position data, a command is given to the movable table 37 so as to stop at a position close to the rear end 3AR of the predetermined front veneer 3A in the tape adhering area 7 through an appropriate distance. It is done.

  When the movable table 37 moves forward, as shown in FIGS. 3 (B), 4 (C) and 5 (B), the inverted comb of the second comb tooth portion 39 provided at the front end of the movable table 37 is used. The tooth shape fits with the comb tooth shape of the first comb tooth portion 31 at the rear end portion of the laminating table 9, and the movable table 37 is connected to the rear end portion 3AR of the front single plate 3A and the rear single portion. The bonding interval with the front end 3BF of the plate 3B stops at an appropriate position.

  Even if the front end 3BF of the rear veneer 3B is placed on the veneer front end placement area 29 of the laminating table 9, the front end 3BF of the rear veneer 3B is largely deformed so that the upper side When it comes to bulge, the above-mentioned deformation can be corrected by the operator pressing lightly from above. If the movable table 37 is moved forward in this correction state, the rear single plate 3B moves forward in contact with the bonding table 9, so that the front end 3BF of the rear single plate 3B is in the tape applying region 7. It stops exactly at a predetermined position of the pasting center position TCL. That is, the accuracy of the bonding interval is improved.

  In this embodiment, the first comb tooth portion 31 is provided at the rear end portion of the bonding table 9, and the second comb tooth portion 39 that fits the first comb tooth portion 31 at the front end portion of the movable table 37. Thus, there is an effect that the portion of the single plate 3B that protrudes forward from the front end of the movable table 37 can be reduced, and an effect that the moving distance of the movable table 37 can be shortened.

  For example, when described with the dimensions shown in FIG. 3A, the length dimension of the portion protruding forward from the front end of the movable table 37 only needs to be slightly larger than the distance E. When the first comb tooth portion 31 and the second comb tooth portion 39 are not provided, the distance E needs to be larger than the distance C (E> C). However, the first comb tooth portion 31 and the second comb tooth When the portion 39 is provided, the distance A needs to be larger than the distance C (A> C). However, since the distance E in the latter case is (AF), it can be made smaller by the depth F of the first comb tooth portion 31 (and the second comb tooth portion 39) than in the former case. Therefore, the moving distance of the movable table 37 can be reduced.

  Next, when the frame 13 of the tape applicator 11 is lowered, the leading end side of the connecting tape 5 previously drawn out from the reel inside the frame 13 is drawn to the lower surface side of the frame 13, so that the leading end side of the connecting tape 5 is It is pressed and stuck to the left end side in FIG. 2 of the end portions 3AR and 3BF of the single plates 3A and 3B on the bonding table 9 from above by a pressing roller. Then, when the frame 13 of the tape applicator 11 moves to the right in FIG. 2, the connecting tape 5 is pressed by the pressing roller while being pulled out from the reel, so that the connecting tape 5 is attached to each of the single plates 3A and 3B. The single plates 3A and 3B are connected by being attached so as to cover the end portions 3AR and 3BF. Thereafter, the connecting tape 5 is cut by the tape cutting portion on the right end side in FIG. The frame 13 returns to the original position.

  In response to a command from the control device, the protrusion 41 is immersed below the upper surface of the movable table 37, air is blown out from a plurality of small through holes 43 on the upper surface of the movable table 37, and the rear single plate 3 </ b> B is air floated. Are switched as follows. On the other hand, since the belt 19 of the single plate fixed transport device 15 is driven again and the front single plate 3A is transported forward in the transport direction, both the single plate 3B on the rear side connected to the front single plate 3A are also included. It is conveyed forward. At the same time, the movable table 37 moves backward and returns to the original position, and air blowing from the plurality of small through holes 43 stops, and the protrusion 41 protrudes upward from the upper surface of the movable table 37.

  When the front single plate 3A and the rear single plate 3B are transported forward in the transport direction, as described above, the position of the rear end portion 3BR of the rear single plate 3B is an end portion. Based on the detected data, the rear end 3BR of the rear veneer 3B stops at a predetermined position in the tape application region 7 based on the detected data, as shown in FIGS. 1 and 4A. It will be in the initial state.

  By repeating the operation as described above, the plurality of single plates 3 </ b> A and 3 </ b> B are long connected with the connection tape 5.

  From the above, according to the single plate connecting apparatus 1 of this embodiment, the rear end portion 3AR of the front single plate 3A and the next single plate 3B on the next rear side are disposed on the rear side of the tape application region 7. An end position sensor 33 for detecting the position of the front end 3BF, a single plate fixed transport device 15 for transporting the front single plate 3A forward, and the next rear single plate 3B are moved forward for positioning. A movable table 37 as a single plate moving and conveying device, and position data of the rear end portion 3AR of the front single plate 3A by the end position sensor 33 and a front end of the next rear single plate 3B. By controlling the moving distance of the front single plate 3A by the single plate fixed conveying device 15 and the moving distance of the next rear single plate 3B by the movable table 37 based on the position data of the section, The rear end 3AR of the front veneer 3A and the next The distance between the front end 3BF of the rear veneer 3B can be brought close to the correct position. In other words, the interval between the butted portions of the single plates 3A and 3B can be controlled to a position that is as narrow as possible (closer) and never overlaps in the thickness direction of the single plate 3.

  In addition, a single plate front end placement region 29 for placing the front end portion 3BF of the rear single plate 3B at the tape attachment height position PL is provided at the rear portion of the tape application region 7, and the movable table 37 is configured as described above. When the rear single plate 3B is installed, the front end 3BF of the rear single plate 3B is configured to stand by at a position where it can be placed in the single plate front end placement region 29. No matter how much the front end 3BF of the rear single plate 3B hangs down, only the rear single plate 3B is placed on the movable table 37, and the hanging portion is placed in the single plate front end placement region 29. Therefore, the tact time can be corrected efficiently without extending.

  Therefore, even if the rear single plate 3B advances, the rear single plate 3A and the rear end portion 3AR of the front single plate 3A and the next are not caught between the bonding table 9 and the movable table 37. The distance from the front end 3BF of the rear single plate 3B can be advanced to a good state.

  Therefore, since the single plates 3A and 3B can be connected to each other in a good state by attaching the connecting tape 5, even if the connected single plates 3 are wound in a roll shape, wrinkles and swelling do not occur. Since the peeling operation of the connecting tape 5 becomes good in the subsequent process, the yield can be improved.

  In addition, since each of the above operations is automatically performed, it is possible to efficiently connect the plurality of single plates 3A and 3B.

  The present invention is not limited to the embodiment of the invention described above, and can be implemented in other modes. For example, when the movable table 37 moves forward, it is possible to cope with the structure in which the tip of the movable table 37 is retracted under the bonding table 9 or the structure in which the movable table 37 is bent so as not to interfere with the bonding table 9. is there.
