Further, the present invention relates to a method for processing the next process, an apparatus for connecting the members to each other, and an apparatus for pressing and sticking a tape to the members.

  Conventionally, as a method of manufacturing a printed wiring board in which circuits are formed on both surfaces of a thin plate-like member, a long member (a member in which a thin conductor film is formed on both surfaces of a thin plate-like base member such as polyimide) is predetermined. The cut members are overlapped with each other, and through holes are simultaneously formed. Through holes are plated in the through holes, and etching is performed on both surfaces of each member subjected to the through holes. A method of forming a circuit is known.

  The through-hole plating is performed for electrically connecting circuits formed on both surfaces of the printed wiring board to each other.

  In the conventional method, when a circuit is provided for each member plated with the through hole, a circuit is formed for each member separated by one.

  By the way, in the printed wiring board manufacturing method, since the through holes for through-hole plating are formed almost simultaneously with a plurality of members superimposed, the through holes can be efficiently formed. When a circuit is formed on both sides, a circuit is formed for each member separated from each other, and therefore there is a problem that the circuit cannot be formed efficiently.

  In the connecting device, the roller is urged by an actuator such as a pneumatic cylinder, and the member is sandwiched and conveyed by each roller. Therefore, the force to sandwich the member becomes uneven in the longitudinal direction of the roller, and the member May be bent and conveyed.

  As described above, when the members are bent and conveyed, the members may be bent and connected.

  Further, in the apparatus for connecting, since the connecting tape is attached to the abutting portion of each member and the members are connected to each other by the operator's manual work, the members cannot be connected efficiently. There is.

  Note that the above-described problem in transporting is a problem that occurs not only when transporting a member of a printed wiring board but also when transporting a thin plate-like member having flexibility, for example.

  In addition, the problem in connecting the above-mentioned members is not only when the members of the printed wiring board are connected to each other, but also with the linear end surface provided on the plate-like first member and the plate-like first surface. This is a problem that also occurs when the linear end surfaces provided on the two members are brought into contact with each other and connected with a connecting tape.

  The present invention has been made in view of the above problems, and a printed wiring board having a circuit on both surfaces and having a through hole for electrically connecting the circuits on both surfaces to each other is provided. It aims at providing the manufacturing method of the printed wiring board which can be manufactured efficiently.

According to the first aspect of the present invention, in the method for manufacturing a printed wiring board, a cutting step of cutting a long member having a predetermined width into a predetermined length at a cutting line extending in the width direction, and the cutting A perforating step of overlapping a plurality of formed members with each other to form a through hole, a plating step of performing through-hole plating on each member with the through holes formed, and end portions of the respective members facing each other a member connecting step for connecting the respective members together, the connected member in sending to the longitudinal direction, possess a circuit formation step of forming a circuit on the member, the member connecting step, each member The cut end faces are arranged close to each other, and a connecting tape having a predetermined width is stretched in the extending direction of the adjacent end faces so as to extend from one surface in the thickness direction of each member. Close to each other Applied so as to cover the position, the a step of connecting the members together, feeding of the member in the circuit formation step, the printed wiring the member is configured to be made to adsorb in vacuo adsorbable belt conveyors It is a manufacturing method of a board.

According to the first aspect of the present invention, a printed wiring board having circuits on both sides and having through holes for electrically connecting the circuits on both sides to each other is manufactured more efficiently than in the past. There is an effect that can be.

  FIG. 1 is a diagram showing an outline of a method for manufacturing a printed wiring board according to an embodiment of the present invention.

  The printed wiring board (printed circuit board) manufactured by the manufacturing method according to the embodiment of the present invention is provided with a thin conductive film (for example, a conductive film formed of copper) on both the front and back surfaces in advance. In addition, the conductive film of the thin plate-like member (material) W3 having flexibility is processed and manufactured.

  Here, the manufacturing method of the printed wiring board will be described in detail.

  First, a long member having a predetermined width is cut into a predetermined length at a cutting line extending in the width direction using a cutting machine (S1).

  A plurality of the cut members W3 are overlapped with each other, and through holes are formed in the respective members W3 almost simultaneously (S3), and through holes are plated on the respective members W3 in which the through holes are formed (S5).

  In order to prevent the members W3 plated with the through-holes from overlapping each other in the thickness direction, the members W3 are connected to each other and formed long with the ends of the members W3 facing each other (S7).

  When the connected and long member W3 is extended in the longitudinal direction and sent, a thin circuit is formed (S9).

  Subsequently, the connected members W3 are separated (S11), and after this separation, thin coverlays are attached to both surfaces of the member W3 (S13) to manufacture the printed wiring board.

  Here, each of the steps will be described in detail.

  In the member connecting step of connecting the members W3 to each other, the cut end surfaces of the members W3 are brought close to each other (in contact with or slightly apart from each other, or in the vicinity of the end surfaces). Each of the parts W3 is arranged in such a manner that the portions overlap each other in the thickness direction of the member, and a connecting tape having a predetermined width is stretched in the extending direction of the adjacent end faces. Affixing is performed so as to cover the parts close to each other from one surface in the thickness direction, and the members W3 are connected to each other.

  In the punching step of making a through-hole for through-hole plating in the member W3, the plurality of members (about 20) are overlapped so that the end surfaces of the members W3 coincide with each other, and the plurality of members Almost simultaneously with W3, a through hole is made using a punch or a drill.

  In the circuit forming step for forming the circuit, the member W3 is long formed in the connecting step and is wound around the outer periphery of the first member (first bobbin) having a cylindrical side surface shape, for example. Is transferred to the outer periphery of a second member (second bobbin) having a cylindrical side surface shape, a circuit is formed on the member W3 by an etching process.

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

  Subsequently, a part of the thin conductive film is removed by an etching process, and a circuit having the same form as the circuit of the pattern substrate is formed on both surfaces of the member W3. Thereafter, the dry film remaining on both surfaces of the substrate is removed.

  According to the method for manufacturing a printed wiring board, a plurality of cut members W3 are overlapped with each other to form a through hole, and through hole plating is performed on each member W3 with the through hole formed. The through-holes can be efficiently formed, and the members W3 plated with through-holes are connected to each other, and the circuit is formed when the connected members W3 are extended and sent in the longitudinal direction. The circuit can be formed almost continuously, and the circuit can be formed efficiently.

  That is, a printed wiring board having circuits on both sides and having through holes for electrically connecting the circuits on both sides can be manufactured more efficiently than in the past.

Although details will be described later, the tape 33 is attached to the member W3 by moving the frame 33 (roller 59) of the tape applicator 29 from one end to the other end in the width direction of the member W3. It is pasted.

  In the initial state, the tip of the tape P1 extending from the reel 37 is present at the position cut by the cutter 53, and the tape P1 is attached to the tape suction member of the tape pulling means 47. 49 is vacuum-adsorbed. The tape adsorbing member 49 is located on the side closest to the first roller 41.

  Further, in the initial state, the roller 67 of the second tape pressing means 65 is located at the rising end.

  From the initial state, the tape adsorbing member 49 moves in the direction of the cutter 53 and pulls out the tape P1 while vacuum-adsorbing the tape P1. By pulling out, as shown in FIG. 6, the tip end portion of the tape P <b> 1 is slightly away from the cutter 53 than the lower end portion of the roller 59 (on the roller 67 side of the second tape pressing means 65). To position.

  Subsequently, when the frame 33 is lowered by the first moving means 61, as shown in FIG. 7, the tip end portion of the tape P1 and one end portion of the member W3 come into contact with each other. At the contacted portion, the tape P1 is sandwiched between the member W3 and the roller 59, and the roller P59 biases the tape P1 toward the member W3 so that the tape P1 sticks to the member W3. ing.

  Note that immediately after the state shown in FIG. 7 is reached, the suction of the tape P1 by the tape suction member 49 is released, and the tape P1 can move freely with respect to the tape suction member 49. ing.

  After the vacuum suction by the tape suction member 49 is released, the frame 33 is moved to the other side of the member W3 by the second moving means 63 while the tape P1 is urged toward the member W3 by the roller 59. Move to the end side. During the movement by the second moving means 63, as shown in FIG. 8, the tape P1 affixed to the member W3 is further pressed toward the member W3 by the second tape pressing means 65. .

  Subsequently, as shown in FIG. 9, when the cutter 53 is positioned almost directly above the other end of the member W3, the movement of the frame 33 by the second moving means 63 is temporarily stopped, and the The tape P1 is cut with a cutter as shown in FIG.

  Thereafter, the movement of the second moving means 63 is started again, and as shown in FIG. 11, the frame until the roller 67 of the second tape pressing means 65 is positioned at the other end of the member W3. 33, and thereafter the movement of the frame 33 by the second moving means 63 is stopped.

  Thereafter, as shown in FIG. 12, the first moving means 61 moves the frame 33 in a direction away from the table 31 (upward), and the tape adsorbing member 49 is moved to the tape reverse running preventing means. The tape P1 is vacuum-sucked by the tape suction member 49.

  Subsequently, the frame 33 is moved in the direction of one end of the member W3 by the second moving means 63, and the initial state shown in FIG. 5 is obtained.

  By repeating such an operation by the member connecting device 1 and the tape attaching device 29, each member W3 is long connected by the connecting tape P1.

  According to the member connection device 1, since the member W3 is conveyed by being vacuum-sucked, the member W3 can be held with a uniform force, compared to the case where the member is sandwiched between rollers as in the prior art. It is possible to avoid that the member W3 is bent and conveyed when the operation is performed.

  Then, the member W3 is bent and conveyed, thereby avoiding the possibility that the members W3 are bent and connected.

  In addition, since the member W3 is vacuum-sucked, the pressure applied to the member is smaller and the member (printed wiring board) is less likely to be scratched than when the member is sandwiched between rollers as in the prior art. .

  Further, according to the member connecting apparatus 1, since the member W3 connected by the tape attaching means 7 and conveyed by the conveying means 5 is wound around the reel 9, the member W3 after connection is saved in space. Can be stored efficiently.

  Moreover, according to the member connection apparatus 1, since the member is conveyed by the belt conveyor 17 which can convey the member W3 while being vacuum-sucked, the member W3 can be continuously and efficiently conveyed without meandering. .

  Furthermore, according to the member connection apparatus 1, since the protrusion 25 is inserted into the through hole W3E provided in the member W3 and the member W3 is positioned, the member W3 can be positioned reliably and easily, When connecting the members W3 to each other, the member W3 can be vacuum-sucked, so that when the member W3 is connected, the member W3 can be prevented from being lifted from the table 31, and the member W3 can be conveyed. In doing so, since the member W3 can be blown very weakly, the table 31 and the member W3 are separated from each other when the member W3 is conveyed, and the member W3 can be prevented from being damaged.

  If a through hole plated with the through hole is used as the through hole W3E for positioning, it is not necessary to provide a through hole for positioning separately, and the configuration of the printed wiring board is simplified.

  Further, according to the tape applicator 29 that operates as described above, since the connecting tape P1 can be applied to the members W3 and the members W3 can be connected to each other without manual intervention, The member W3 can be connected more efficiently.
