[Prior Art] In the electronic device, as the electronic components for mounting the surface of the surface of the 1C chip, the resistor, the capacitor, and the like are miniaturized, the printed wiring board on which these are mounted is often required to have a high density and a plurality of layers. The multilayer printed wiring board is composed of a conductor layer exposed to the outside of the front and back layers and a conductor layer of an inner layer which is not exposed to a plurality of layers. An insulating substrate is interposed between the respective conductor layers to form a structure in which the conductor layer is followed by the substrate. In the multilayer printed wiring board, for example, at least two reference holes for pre-positioning are to be cut into the double-sided wiring board, and a pattern of the front and back surfaces is formed on the basis of the reference hole. The pattern of the front and back of the two-sided printed wiring board is flat to maintain its position. A pattern of the same coordinate position is used for the double-sided wiring board of such a plurality of sheets to form a pattern or the like. In the pattern of the double-sided printed wiring board formed on the inner layer board, in addition to the pattern of the single wiring board, a guide mark for a new reference hole and a guide mark for displaying the position of the reference hole for the identification of the front and back are prepared. These guide marks are also formed in the etching process. The double-layer printed wiring board for the inner layer which is formed by laminating a plurality of sheets is etched, and the positional relationship of the patterns of the conductor portions formed in the respective wiring boards is made uniform, which is called a junction layer (L a y u p ). In order to carry out the layering, a jig plate of -5- (2) 1310709 plurality of pins is prepared. Usually, the pin is placed at a position suitable for the set reference hole. In order to more accurately match the pattern of each layer of the completed multilayer wiring board, a reference hole for a new layer is sometimes provided. A two-sided wiring board that has been inscribed by a piece of contact is inserted into the pin of the jig plate at its reference hole and placed on the jig plate. A substrate material (referred to as a prepreg) in which the heated reference holes are heated is placed thereon. Also, the other two-sided wiring board is inserted into the pin of the jig plate at its reference hole and overlaps the jig plate. At this stage, if the outer periphery of the prepreg placed therebetween is printed with copper foil of the conductor material on both sides of the layered layer, the prepreg between the double-sided wiring boards is heated and the bonding between the conductors is completed. Then, the reference hole of the case is cut, and the base conductor wiring pattern is etched, the through plating process, the rustproof process, and the like, and the plate is cut into a reference hole formed in the multilayer printed wiring board and formed in the desired shape. In the hot press, in addition to the pattern of the single wiring board forming the multilayer printed wiring board, the mark of the part is set in the etching process, and the coordinates of the mark are set as the holding system. The two sides of the wiring board and the finish layer. When the prepreg and the pressurization are placed on both sides of the brushed wiring board, the copper foil or the insert is hardened (insulated) and changed on the substrate, and the opening of the outermost layer is performed in accordance with the inner layer of the multilayer wiring board as a reference. Hole processing, etc. Further, the electric power is divided into a single wiring by mechanical processing to complete the multilayer printed wiring board. In the process, the reference hole is two types of reference holes after the use of the layering process. In the two-sided printed wiring board of the inner layer described above, the guide mark for a plurality of reference holes is also etched. The coordinates of the pattern of the single wiring board and the position of the position can be used to identify the coordinates of the pattern constituting the circuit -6-(3) 1310709. Observe the plurality of guide marks and the like. In order to obtain the coordinates of the new reference hole based on the result calculated from the observation ,, and to make the opening of the reference hole, a hole opening device is usually used. In the case of the processing object of the hole opening device, the first is the multilayer printed wiring board after the end of the layering process and the hot pressing process, and the second is the double-sided printed wiring board before the layering process of the member constituting the multilayer printed wiring board. . That is, in the case of the workpiece of the reference hole opening device, there are a plurality of printed wiring boards of both sides, and the latter will be collectively referred to as a workpiece or sometimes only as a printed wiring board. As described above, the front and back surfaces of the multilayer printed wiring board which is heated and pressurized by hot pressing are covered with a non-scale conductor layer, and the visible light rays are not visually recognized to clearly indicate the guide marks formed on the inner layer. In view of the fact that it is impossible to observe with visible light, various observation methods are being investigated. For example, other measurement methods such as ultrasonic waves that do not use visible light are often used, and X-ray (reference hole) opening machines are often used. The multilayer wiring board is seen with a weak X-ray, and the guide marks of the conductor layers formed on the inner layer are observed. The processing accuracy of the printed wiring board is determined by the accuracy of the reference hole. For the technique of improving the processing precision of a printed wiring board, for example, there is a second patent document. Patent Document 1 describes a technique for performing correct opening of a printed circuit board with a simple configuration. The technique of Patent Document 1 is to prepare a jig plate in which a plurality of holes are provided in a jig plate on a work table. The transmission image of the plurality of holes is taken by two imaging means to obtain the positional deviation between the center position and the center of the image. Since the interval between the holes is known, the interval between the two imaging means can be calculated. Here, setting the printed substrate 'takes two identification marks by two cameras (4) 1310709, and performs image processing to obtain the positional deviation between the center position and the image center, and the two imaging means The interval between the identification marks is calculated by the interval between them. Here, only the amount of error in the interval between the identification marks and the interval between the holes to be perforated is corrected, and the opening position is set, and the drill hole is opened here.

Yes) ,X線攝影機6的攝像中 心與鑽頭7的開孔位置的關係應是一致於治具板5〇的攝 像孔中心與治具孔中心(在容許誤差的範圍)。 於是,將在原封不動地保持X線攝影機6與鑽頭7的 位置之下,在印刷配線板60中開鑿基準孔60h。亦即,在 原封不動地使X移動架台10、Y移動架台Π及鑽頭移動 架台7a保持於校正完成的狀態下,將開鑿基準孔60h的 -23- (20) 1310709 印刷配線板60載置於治具板50,調節可動工作台1 2 ’而 使印刷配線板60的標記60m對合於X線攝影機6的攝像 中心(步驟S 7 )。 然後,在原封不動地保持該狀態下,使鑽頭7昇降, 而來開鑿基準孔60h (步驟S 8 )。此刻,如上述’最好是 與在鑽頭位置的校正時於校正用基板61中開鑿孔61h同 動作來開鑿基準孔60h。 圖1 〇是表示將印刷配線板6 0載置於治具板5 〇 ’使標 記6 0m對合於X線攝影機6的攝像中心’而用鑽頭7開 鑿基準孔6Oh之工程。圖1 0的(a )是表示將印刷配線板 60載置於治具板50,而X線攝影機6的攝像中心與標記 6 0m偏移的狀態。圖10的(b)是表示調節可動工作台12 來使印刷配線板60的標記60m對合於X線攝影機6的攝 像中心之狀態。圖1 〇的(c )是在印刷配線板6 0的標記 6〇m對合於X線攝影機6的攝像中心之狀態下’用鑽頭7 來開鑿基準孔60h的狀態。 爲了使印刷配線板60的標記60m對合於X線攝影機 6的攝像中心,而使用圖6所説明的可動工作台1 2的X -Y-Y機能。首先,將可動工作台12平行移動於X軸及Y 軸方向,而例如使左側的標記6 0m對合於一方的X線攝 影機6的攝像中心。其次,藉由圖像計測來測定2個X線 攝影機6與右側的標記60m所成的角度,以能夠形成無角 度誤差的方式來調節圖6的Y2工作台12f。由於標記60m 是非一致於可動工作台1 2的框架1 2 g的支點’因此隨著 -24 * (21) 1310709 Y2工作台1 2f作動’左側的標記60m會偏離χ線攝影機 ό的攝像中心’所以事先計算偏移量來調節X 1工作台1 2 C 及Υ 1工作台1 2e。亦即’以可動工作台1 2的旋轉中心能 夠形成已經對合於X線攝影機6的攝像中心的標記6〇m 的中心之方式來控制可動工作台1 2。 回到圖7的流程圖’在印刷配線板6 〇中開鑿基準孔 60h之後’判定是否有應開鑿基準孔6〇h的印刷配線板6〇 (步驟S9 )。若有應開鑿基準孔6〇h的印刷配線板60 ( 步驟S 9 ;

Further, the jig holes 53 divided into two are respectively cut around the imaging hole 52. The center of the imaging hole 52 and the center of the jig hole 53 are formed correctly with respect to the position of the mark 60m and the cutting reference hole 60h of the printed wiring board 60, respectively. In the jig plate 50, as described above, the adsorption portion 5 1 is formed at the center portion. The plate 5 1 b (see FIG. 5( c )) in which the hole 5 1 a is bored is fitted in the adsorption portion 5 1 , and the air is sucked by the intake pipe 51 c connected to the suction device (not shown). A workpiece (printed wiring board 19-(16) 1310709 ό〇 or calibration substrate 61) placed on the jig plate 50. The printed wiring board 60 is placed such that the mark 60m is located substantially at the center of the imaging hole 52 (see FIG. 5). FIG. 6 is a view showing the operation of the movable table 12. 6(a) is a plan view of the movable table 12, (b) is a plan view of the movable table 12 in a rotating state, and (c) is an elevational view of the movable table 12. The movable table 12 is supported by an XI table 1 U XI table 12d that moves in the X direction. The XI table 12c is moved in the X-axis direction by a ball screw nut. The XI table 12d is connected to the X-direction table 12c and the XI table 12d is connected by the frame 12g along the piece 12d2. Therefore, the XI table 12d is operated by the XI table 12c. A Y1 table 12e is provided on the XI table 12c. The Y2 table 12PY1 table 12e and Y2 table 12f are provided on the XI stage 12d to operate independently in the γ-axis direction. The frame 12g is screwed to the Y1 table 12e and the Y2 table 12f. By operating the table 12e and the 工作2 table 12f simultaneously in the same direction, the frame moves in parallel in the Y-axis direction. For example, if the Y1 table is fixed and the Y2 table I2f is actuated, the table IJ XI table 12d is free to move in the X direction, so the frame 12g will be rotated by the Y1 table 12e. For example, as shown in Fig. 6(b), when the frame 1 2g is rotated by an arc, the distance between the Y1 table axis of the frame 12g and the Y2 table axis is set such that the Y2 table 12f is actuated by Lsine. At this moment, the XI workbench can (b) be ok 2c and the rod and X guide work interlocking work from t Y1 丨12g 1 2e to move the heart as long as L, 1 2d -20- (17) 1310709 is moving L ( L-cose ). The position and angle of the frame 12g are measured by observing the two holes 12h, 12i provided in the frame 12g. Since the movable table 12 does not have to be moved at a large angle, a linear motion can be performed as in the Y 1 table 1 2e or the Y2 table 1 2f. By realizing the linear motion of replacing the rotational motion of the movable table 12 with the Y2 table 12f (or the Y1 table 12e), it is possible to obtain an accurate angular displacement with a simple mechanism. g Next, the operation of the hole opening device 1 will be described with reference to Fig. 7 to Fig. 1 . FIG. 7 is a flowchart showing an example of the operation of the hole opening device 1. Fig. 8 is a view showing a state in which the position of the drill 7 is corrected using the correction substrate 61. Further, as described above, the operation of the aperture device 1 is that the control unit 21 coordinates the main memory unit 2, the external memory unit 23, the operation unit 24, the input/output unit 6, the X-ray camera 6, the X mobile station 10, and the Y. The gantry 11, the movable table 12, and the drill moving table 7a are moved. Beforehand, the interval between the two X-ray cameras 6 is the interval between the marks 60m of the printed wiring board φ (hereinafter referred to as the substrate) 60, and the position of the X moving stage 10 is determined. Further, the position of the drill 7 is set to the X-ray camera 6 so that the position of the reference hole 60h of the mark 60m can be formed. That is, when the X-ray camera 6 is located at the center of the imaging hole 52, the drill head 7 is located at the jig hole 53. First, the center of the imaging hole 52 of the jig 50 is correctly aligned with the imaging center of the X-ray camera 6 (step s 1 ). At this time, only the movable table 12 can be moved, or the X moving stage and the gamma moving stage 11 can be operated. However, the relative position of the X-ray camera 6 and the drill bit 7 does not change. -21 - (18) 1310709 Next, the calibration substrate 61 is placed on the jig plate 50, and the center of the imaging hole 52 of the jig plate 50 is correctly aligned with the imaging center of the X-ray camera 6. In this state, the drill bit 7 is raised and lowered, and the boring hole 6 1 h is opened (step S2). This state is shown in (a) of Fig. 8 . In a state where the imaging center of the X-ray camera 6 is aligned with the center of the imaging hole 52, the hole 6 1 h is cut at four places of the jig hole 5 3 of the correction substrate 6 1 . In order to drill the hole 61h in the correction substrate 61 by the drill 7, the drill bit 7 can be lifted one by one to be cut one by one, or all of them can be simultaneously cut. When the reference hole 60h is cut into the printed wiring board 60 to be described later, it is preferable to operate the same. The movable table 12 is moved, and the opening position is moved to the imaging center of the X-ray camera 6, and the error of the hole 6 1 h to be cut in the jig hole 53 and the correction substrate 6 1 is measured (step S3). (b) of Fig. 8 shows a case where the inside opening position is moved to the imaging center of the X-ray camera 6. (c) of Fig. 8 is a view showing when the opening position of the front side is moved to the imaging center of the X-ray camera 6. In the present embodiment, since the position of the hole 6 1 h is bilaterally symmetrical, it can be measured simultaneously. When the position of the hole 6 1 h is not bilaterally symmetrical, it is measured one by one to the imaging position of the X-ray camera 6. Fig. 9 is a view showing an example of an error of the jig hole 53 and the hole 61h. In the center of the jig hole 53, the center of the hole 61h is shifted by Δχ in the X-axis direction and offset by Ay in the Y-axis direction. Moreover, the error of the X-ray camera center and the center of the jig hole was also measured. The error between the X-ray camera camera center and the center of the jig hole is the movement error of the movable table 12. Returning to the flowchart of Fig. 7, second, the position of the drill bit 7 (bit cutter 7b) -22-(19) 1310709 is corrected (step S4). The hole 61 h was originally opened at the center of the jig hole. Therefore, the position of the drill bit 7 is corrected for the X-ray camera 6 in such a manner that B is sufficient to eliminate the error of the center of the hole and the center of the hole 6 1 h. For example, as shown in Fig. 9, if the errors are Δχ and Ay, the position of the drill bit 7 is corrected by the amount of -δχ and -. The error is corrected in the same manner for the entire drill bit 7. That is, if the error correction of the entire drill bit 7 is not completed (step S5; No), the steps, _S3 and step S4 are repeated. When all the drills 7 complete the error correction (step S5; Yes), if the error is judged whether or not the error is an allowable range (step S6), and the error is not within the allowable range (step S6; No), a new correction substrate is to be used. 61 is placed on the jig plate 50' for correction of the bit position (step S2 is repeated to step S6). The tolerance of the center of the jig hole 5 3 and the center of the hole 6 1 h is, for example, determined by the resolution of the X-ray camera 6 and the decomposition of the drill moving frame 7a. In a state where the error of the center of the jig hole 53 and the center of the hole 6 1 h is within the allowable range (step S6; Yes), the relationship between the imaging center of the X-ray camera 6 and the opening position of the drill bit 7 should be identical to The center of the camera hole of the fixture plate and the center of the fixture hole (in the range of tolerance). Then, the reference hole 60h is cut in the printed wiring board 60 under the position where the X-ray camera 6 and the drill 7 are held as they are. In other words, the X-moving gantry 10, the Y-moving gantry, and the drill-moving gantry 7a are held in the state where the correction is completed, and the -23-(20) 1310709 printed wiring board 60 on which the reference hole 60h is cut is placed. The jig 50 adjusts the movable table 1 2 ', and the mark 60m of the printed wiring board 60 is aligned with the imaging center of the X-ray camera 6 (step S7). Then, while the state is maintained as it is, the drill 7 is moved up and down to drill the reference hole 60h (step S8). At this point, as described above, it is preferable to open the reference hole 60h in the same manner as the hole 61h in the correction substrate 61 at the time of correction of the bit position. Fig. 1 is a view showing a process in which the printed wiring board 60 is placed on the jig plate 5 〇 ' so that the mark 60 0 is aligned with the imaging center ' of the X-ray camera 6 and the reference hole 6Oh is drilled by the drill 7. (a) of Fig. 10 shows a state in which the printed wiring board 60 is placed on the jig 50, and the imaging center of the X-ray camera 6 is shifted from the mark 60m. (b) of Fig. 10 shows a state in which the movable table 12 is adjusted to match the mark 60m of the printed wiring board 60 to the image center of the X-ray camera 6. (c) of FIG. 1 is a state in which the reference hole 60h is drilled by the drill bit 7 in a state where the mark 6〇m of the printed wiring board 60 is aligned with the imaging center of the X-ray camera 6. In order to match the mark 60m of the printed wiring board 60 to the imaging center of the X-ray camera 6, the X-Y-Y function of the movable table 12 described with reference to Fig. 6 is used. First, the movable table 12 is moved in parallel in the X-axis and Y-axis directions, and for example, the left mark 60m is aligned with the imaging center of one of the X-ray cameras 6. Next, the angle between the two X-ray cameras 6 and the mark 60m on the right side is measured by image measurement, and the Y2 table 12f of Fig. 6 is adjusted so that the angle error can be formed. Since the mark 60m is non-identical to the fulcrum of the frame 1 2 g of the movable table 1 2, so with the -24 * (21) 1310709 Y2 table 1 2f action 'the mark 60m on the left side will deviate from the camera center of the 摄影 line camera '' Therefore, the offset is calculated in advance to adjust the X 1 table 1 2 C and the Υ 1 table 1 2e. That is, the movable table 12 is controlled such that the center of the mark 6〇m of the imaging center of the X-ray camera 6 can be formed by the center of rotation of the movable table 12. Returning to the flowchart of Fig. 7, 'after the reference hole 60h is cut in the printed wiring board 6', it is determined whether or not there is a printed wiring board 6A to which the reference hole 6?h is to be cut (step S9). If there is a printed wiring board 60 to which the reference hole 6〇h is to be cut (step S9; Yes), the process returns to step S7 to cut the reference hole 6〇h of the printed wiring board 6〇. If there is no printed wiring board 60 to be opened (step S9; No), the operation is terminated. In this way, as long as the conditions of the hole opening device 1, such as the wear or temperature of the drill bit 7b, are not changed, the position of the drill bit 7 can be corrected once, and the batch of the plurality of printed wiring boards 60 can be correct. Ground the reference hole 60h. Since the perforating device 1 of the present invention is in response to the jig plate 50 for feedback control, the opening accuracy of the perforating device 1 of the present invention is in accordance with the accuracy of the jig plate. As long as the accuracy of the imaging hole 52 of the jig 50 and the jig hole 53 are improved, the accuracy of the reference hole 60h of the printed wiring board 60 can be improved. In the hole opening method of the present invention, when the position of the drill bit is corrected, the position of the drill bit 7 is actually moved and adjusted so that the hole 7 can be opened at a specific position. Once the adjustment is completed, the drill bit 7 will maintain the position as it is. It will not move from this location in the future. Therefore, the positional deviation of the reference hole 60h is not caused by the error in moving the drill 7. -25- (22) 1310709 The hole opening device of the present invention is provided with a jig hole 53 in a movable table 12 on which a printed wiring board 60 is placed. The movement result is fed back with the jig hole 5 3 as a reference, whereby the positioning can be performed while verifying that the movement is at the correct position. By this method, the error in moving the opening position of the printed wiring board 60 to the position of the drill bit can be eliminated. Others, the aforementioned hardware configuration or flowchart is an example thereof, and may be arbitrarily changed and corrected. In the above-described embodiment, the number of the marks on the printed wiring board is two at the both ends, and the reference marks of the two marks are cut at equal intervals for each mark. However, the present invention is not limited thereto. For example, the position of the mark may also be non-left-right symmetric, or the reference holes are not equally spaced. Further, in the case of the mark, the reference hole may not be two places but one or more places.
