[Figure 8] 1 is an example of a hardware configuration of a computer for realizing the functions of a confirmation device according to the present disclosure. DETAILED DESCRIPTION OF THE INVENTION
[0014] Hereinafter, each embodiment will be described with reference to the drawings. In all drawings, the same or corresponding components are denoted by the same reference numerals, and common descriptions will be omitted. It should be noted that in this disclosure, the drawings may relate to one or more embodiments.
[0015] First Embodiment Hereinafter, an embodiment according to the present disclosure will be described with reference to the drawings. As shown in FIG. 1, the wiring board 1 includes a substrate 2 and a solder resist 3. For example, the wiring board 1 may be a PWB.
[0016] The substrate 2 has wiring 21 . The solder resist 3 is an insulating material. The solder resist 3 covers the wiring 21 . In FIG. 1, an area E shown in the center of the board 2 is a component mounting area where electronic components are mounted.
[0017] For example, the substrate 2 may have a copper foil portion including wiring 21 and soldering pads. In this case, the solder resist 3 may cover the wiring 21 while avoiding the soldering pads. Furthermore, the solder resist 3 may cover the substrate 2 while avoiding the peripheral edge portion 2A of the substrate 2 and the substrate dividing area 4.
[0018] The substrate dividing area 4 is positioned across the substrate 2 and is a zone for dividing the substrate 2 along the central cutting lines L1 and L2. Then, in the subsequent V-groove processing step, a V-groove is formed along the cutting lines L1 and L2 using a cutting method such as an upper and lower disc cut method or a linear split method. The upper and lower disc cutter is a cutting method that cuts the V-groove with upper and lower rotating circular blades, and is divided into two types: an electric type that forcibly rotates the blade, and a manual type that rotates the blade naturally by pressing on the board. The linear split type is a cutting method that combines a rotating circular blade (upper blade) and a linear blade (lower blade).The V-groove part of the board is set on the lower blade while it is being split, so the cutting line does not shift.
[0019] Next, the confirmation mark 10 (mark) for ensuring that no omissions are made in the V-groove processing step will be described with reference to FIGS. The confirmation mark 10 is placed in the substrate dividing area 4 where the grooves of the substrate 2 will be processed, and is made of the same insulating material as the solder resist 3.
[0020] The confirmation mark 10 is also placed away from the solder resist 3 via an isolation area 11 that has a certain distance between it and the solder resist 3 . Furthermore, this isolation area 11 is provided along the periphery of the confirmation mark 10 with the substrate dividing area 4 interposed therebetween, i.e., it is provided around the entire periphery of the confirmation mark 10, thereby isolating the confirmation mark 10 from the solder resist 3.
[0021] Furthermore, the confirmation mark 10 is not a simple circle or square, but is formed in a special shape (a polygonal shape in the illustrated example) as shown in FIGS. The confirmation mark 10 illustrated in this embodiment is formed in an arrow feather shape with the corners of the periphery (indicated by symbols 10A and 10B in Figures 2 and 3) aligned with the cutting lines L1 and L2 of the substrate dividing area 4. Furthermore, although the illustrated confirmation mark 10 is divided into two separate portions (indicated by reference numerals 12 and 13 in FIGS. 2 and 3), the number of portions into which it is divided can be selected as appropriate.
[0022] Furthermore, such an arrow feather-shaped confirmation mark 10 makes it easy for an operator or a monitoring device to determine whether or not groove processing (the groove processing portion is indicated by the symbol M in Figures 1 and 3) has been performed in the board division area 4 of the wiring board 1 along the cutting lines L1 and L2. In other words, because the confirmation mark 10 has a special shape, it is easy for the worker or the monitoring device to recognize that the confirmation mark 10 before groove processing (see Figure 2) changes to its shape after groove processing (see Figure 3), thereby preventing omissions in groove processing work.
[0023] In the wiring board 1 of this embodiment described above, at the time of design, V-groove processing omission confirmation marks 10 prepared in advance in a library are placed on the front and back surfaces at the V-groove processing locations, thereby clearly indicating the V-groove processing positions. This allows the state of the V-groove to be clearly confirmed during the manufacturing of the wiring board 1 and in subsequent processes such as an inspection process and a component mounting process. That is, before the V-groove processing, the confirmation mark 10 has a shape as shown in the left-hand diagram of FIG. 1 and FIG. 2, but after the V-groove processing, it has a shape with a groove processing portion M as shown in the right-hand diagram of FIG. 1 and FIG. 3, and it can be confirmed whether or not the product is a "good product" that has been V-grooved. As a result, with the wiring board 1 of this embodiment, it is possible to prevent the need to discard the board together with the mounted components or to go back and do the work again, which would occur if the V-groove processing was forgotten.
[0024] On the other hand, if the groove processing portion M is not found in the confirmation mark 10, the wiring board 1 is determined to be a "defective product" in which the V-groove processing has not been performed. This confirmation work can be performed not only by visual inspection by an operator, but also by an image recognition device that has previously stored the shape of the confirmation mark 10 as reference data.
[0025] Furthermore, in the wiring board 1 of this embodiment, the confirmation mark 10 is positioned away from the solder resist 3 on the substrate 2, so that if a burr occurs in the confirmation mark 10 during V-groove processing and the portion peels off, there is little impact on the solder resist 3. Therefore, according to the wiring board 1 of this embodiment, peeling of the solder resist can be suppressed. For example, if peeling of the solder resist can be prevented, short circuits of the copper wires of the substrate 2 can be prevented.
[0026] Second Embodiment Hereinafter, an embodiment according to the present disclosure will be described with reference to the drawings. As shown in FIG. 4, the checking method includes steps S1 and S2.
[0027] The wiring board has a substrate having wiring and a solder resist covering the wiring. In step S1, a mark that is isolated from the solder resist and made of an insulating material is provided in the divided area of the board where the grooves will be processed. In the next step S2, it is determined based on the shape of the mark whether or not groove processing has been performed in the substrate division area where the grooves are to be processed on the substrate.
[0028] According to the above-described confirmation method, if the mark does not show the groove processing area M that would be formed when groove processing is performed, it can be confirmed that the wiring board 1 is a "defective product" in which V-groove processing has not been performed. Furthermore, since the mark is disposed separately from the solder resist on the board, even if a burr occurs in the mark during V-groove processing and the burr peels off, the impact on the solder resist is minimal. Therefore, according to the checking method of this embodiment, peeling of the solder resist can be suppressed.
[0029] Third Embodiment Hereinafter, an embodiment according to the present disclosure will be described with reference to the drawings. As shown in FIG. 5, the wiring board 1-1 includes a substrate 2-1 having wiring 21-1, a solder resist 3-1, and a mark 10-1. The solder resist 3-1 covers the wiring 21-1. The mark 10-1 is provided in the groove processing location 4-1 of the substrate 2-1, is isolated from the solder resist 3-1, and is made of an insulating material.
[0030] With the wiring board 1-1 described above, if the mark 10 does not show the groove processing portion formed after the groove processing, it can be confirmed that the wiring board 1-1 is a "defective product" in which V-groove processing has not been performed.
[0031] Furthermore, since the mark 10-1 is disposed separately from the solder resist 3-1 on the substrate 2-1, even if a burr occurs in the mark 10-1 during V-groove processing and the burr peels off, the impact on the solder resist 3-1 is minimal. Therefore, according to the wiring board 1 of this embodiment, peeling of the solder resist can be suppressed.
[0032] <Fourth embodiment> Hereinafter, an embodiment according to the present disclosure will be described with reference to the drawings. As shown in FIG. 6, the checking method includes steps S20 to S22.
[0033] In step S20, the marks on the wiring board are recognized before grooves are formed on the wiring board 1. The wiring board 1 includes wiring, a solder resist covering the wiring, and a mark formed of an insulating material and isolated from the solder resist in a substrate dividing area where grooves will be processed in the substrate.
[0034] In the next step S21, the mark on the wiring board is recognized after the groove is formed in the wiring board 1. In the next step S22, it is determined whether or not groove processing has been performed in the substrate division area where groove processing is to be performed, based on the shape of the mark.
[0035] According to the above-described confirmation method, if it is determined based on the result of step S22 that the mark on the wiring board does not show the groove processing portion that will be formed after groove processing, it can be confirmed as a "defective product" that has not undergone V-groove processing.
[0036] Furthermore, since the mark is disposed separately from the solder resist on the board, even if a burr occurs in the mark during V-groove processing and the burr peels off, the impact on the solder resist is minimal. Therefore, according to the checking method of this embodiment, peeling of the solder resist can be suppressed.
[0037] Fifth Embodiment Hereinafter, an embodiment according to the present disclosure will be described with reference to the drawings. As shown in FIG. 7, the verification device 100 includes a first recognition unit 101, a second recognition unit 102, and a determination unit 103.
[0038] The first recognition unit 101 recognizes the mark on the wiring board before grooves are formed in the wiring board. The wiring board includes a substrate having wiring, a solder resist covering the wiring, and a mark formed of an insulating material and isolated from the solder resist in a substrate dividing area where the grooves are to be processed in the substrate.
[0039] The second recognition unit 102 recognizes the mark on the wiring board after the groove is formed in the wiring board. The determining unit 103 determines whether or not groove processing has been performed in the substrate division area where groove processing is to be performed, based on the shape of the mark.
[0040] According to the above-described verification device 100, if it is determined based on the result of the determination unit 103 that the mark on the wiring board does not show the groove processing portion that is formed after the groove processing, it can be confirmed as a "defective product" that has not undergone V-groove processing.
[0041] Furthermore, since the mark is disposed separately from the solder resist on the board, even if a burr occurs in the mark during V-groove processing and the mark peels off, the effect on the solder resist is minimal. Therefore, the checking device 100 of this embodiment can prevent the solder resist from peeling off.
[0042] <Hardware configuration of each device> An example of a hardware configuration for realizing all or part of the verification device 100 in the above-described embodiment will be described with reference to FIG. As shown in Figure 8, the verification device includes a computer 90 having the following hardware: a processor 91, a memory 92, a storage / playback device 93, a communication I / F (communication interface) 94, and an IO I / F (input output interface) 95.
