FIG. 4 is a diagram illustrating the configuration of the main control board 300. Note that FIG. 4 shows a front view of the main control board 300 as viewed from the surface 340a (one side). Further, in FIG. 4, for convenience of explanation, some of the electronic components arranged on the main control board 300 are shown, and in reality, electronic components (not shown) are also arranged on the main control board 300. Further, in FIG. 4, for convenience of explanation, the wiring pattern formed on the main control board 300 is omitted. The main control board 300 is mounted on the mass-produced gaming machine 100, and is the same as the one conforming to the type test, whether or not it has been tampered with in the inspection by the Public Safety Commission of the prefecture, etc. It is desirable to be able to determine whether it looks like it.

The main control board 300 is provided with a board main body portion 340. The substrate main body 340 is a double-sided substrate in which wiring patterns are formed on the front surface 340a and the back surface 340b (other surfaces, see FIG. 5). A plurality of electronic components are arranged on the surface 340a of the substrate main body 340. Examples of the electronic components arranged in the board main body 340 include a main CPU 300a (built-in main ROM 300b and main RAM 300c), IC 342, resistor 344, capacitor 346, LED 348, connector 350, switch 352, inductance (not shown) and the like. be.

Here, even if an attempt is made to connect the electronic components to each other by a wiring pattern formed only on the surface 340a, there may be a case where the patterns intersect and cannot be electrically separated. Therefore, these electronic components are connected to each other by a wiring pattern formed on the front surface 340a and the back surface 340b of the substrate main body 340.

Further, a plurality of via holes 354 for conducting the wiring pattern formed on the front surface 340a and the wiring pattern formed on the back surface 340b are formed on the substrate main body portion 340. The details of the beer hall 354 will be described in detail later.

Since the main control board 300 does not conform to the type test unless the electric components that can be arranged are DIP (Dual Inline Package) type electric components mounted on one side according to the rules, the occupied area of the electric components tends to increase. be. Here, if the occupied area is simply increased, the substrate main body portion 340 may become larger or the substrate main body portion 340 may become larger, which may make the arrangement design difficult. Therefore, by devising the arrangement of the electric parts in the substrate main body 340, the increase in the occupied area is suppressed.

The main CPU 300a and the IC 342 are integrated circuits in which electrical components such as transistors, diodes, resistors, and capacitors are integrated. Further, the main CPU 300a and the IC 342 are composed of a main body formed in a flat plate shape and three or more leads 356 (see FIG. 5) protruding outward from the side surface of the long side of the main body. The leads 356 are arranged in the same number and evenly spaced on the two long side surfaces of the main body, and terminal numbers are sequentially assigned in the horizontal direction from the lower left to the lower right in front view, and further, in the horizontal direction from the upper right to the upper left. Terminal numbers are assigned in sequence.

As described above, since the main CPU 300a and the IC 342 are formed vertically symmetrically in the front view, various measures are taken to prevent erroneous recognition of the vertical direction. For example, in an arrangement (normal arrangement) in which the first terminal is in the lower left in the front view, a character string (not shown) is printed in the longitudinal direction at the center of the main body so as to be in the positive direction in the front view. Various notations such as alphabets, numbers, kana, kanji, and symbols can be applied to such character strings.

Further, in the main CPU 300a, an identifier is formed on the left side surface of the short side by cutting out a part of the left side in a semicircular shape so that the terminal 1 is located at the lower left in the front view. Further, in the IC 342, the terminal 1 is arranged at the lower left in the front view, and a circular identifier indicating the position of the terminal 1 is formed in the vicinity of the terminal 1.

The resistor 344, the capacitor 346, and the inductance are composed of a columnar or prismatic main body and leads 356 protruding outward from both ends thereof. The resistance 344, the capacitor 346, and the inductance are arranged parallel to the surface 340a of the substrate main body 340 (along the surface 340a). Further, on the resistance 344, the capacitor 346, and the inductance, endless bands having a color extending in a direction intersecting the direction in which the terminal protrudes (protruding direction) are lined up in the protruding direction on the side surface portion of the columnar main body. Multiple prints are made. Then, the resistance value and accuracy of the resistor 344, the capacitance and accuracy of the capacitor 346, and the inductance and accuracy of the inductor can be specified by the color combination (color code) of the bands arranged in the protruding direction. Although the resistor 344 and the inductor have no polarity, some capacitors 346 have no polarity. It is desirable that the resistance 344, the capacitor 346, and the inductance can be visually determined to have the same performance without reading the color code values. Therefore, by arranging the resistors 344 having the same color code, the capacitor 346, and the inductance in the same direction, it is obvious that they are the same electronic components when visually checked without having to read the values from the color code. It has become.

Here, an example is given in which all the electronic components are arranged on one surface (surface 340a) of the substrate main body 340. In addition, although the example of the DIP type is given as the mounting type of the electronic component, it is not limited to this case, and various mounting such as SIP (Single Inline Package), SOP (Small Outline Package), QFP (Quad Flat Package), etc. are given. The type can be adopted. In DIP, since the distance between terminals is standardized, a single electronic component occupies a certain area. Therefore, the effect of reducing the occupied area by devising the arrangement of the electronic components as shown below is likely to be remarkably generated for the DIP type electronic components.

Further, on the board main body 340, identification displays (CPU, IC1 to IC11, R1 to R9, C1 to C11, corresponding to the main CPU 300a, IC342, resistor 344, capacitor 346, LED348, connector 350, and switch 352 to be mounted, LEDs1 to LED5, CN1 to CN5, SW1) are printed in the vicinity thereof. Here, since the mounting location of the electric component can be visually recognized, it is possible to prevent erroneous mounting. Further, the identification display is arranged at a position that can be visually recognized (not hidden) from the front even after the electric component is mounted. Therefore, it is possible to improve workability even in the confirmation after mounting. Further, in the identification display, a character string is printed so as to be in the positive direction in an arrangement in which the first terminal of the IC 342 is located at the lower left when viewed from the front. Therefore, it is possible to prevent erroneous recognition of the mounting direction of the IC 342.

Further, on the surface 340a, the display directions of such electrical component identification displays (CPU, IC1 to IC11, R1 to R9, C1 to C11, LEDs1 to LED5, CN1 to CN5, SW1) are unified as much as possible. By doing so, workability can be improved even in the confirmation after mounting. Further, with the resin case (not shown) for enclosing the main control board 300 attached to the gaming machine 100, the identification display (CPU) of the main CPU 300a and the identification display (IC1 to IC11) of the IC 342 are all on the front surface. It is attached to the surface of the main control board 300 so as to be in the positive direction visually. As a result, the operator can easily visually recognize the identification number even when the resin case for enclosing the main control board 300 is attached to the gaming machine 100, and the workability can be improved even in the confirmation after mounting. It will be possible.

Further, on the surface 340a, a guidance display for preventing misidentification of the mounting direction of the main CPU 300a and the IC 342 to be mounted is printed. For example, in an arrangement in which the first terminal of the main CPU 300a is in the lower left when viewed from the front, when an identifier is formed on the left side surface in the lateral direction by cutting out a part of the left side in a semicircular shape, the main CPU 300a is used as a substrate. A guidance display imitating the shape of the notch is printed on the substrate near the semicircular notch so that it can be placed correctly on the top. Further, when the IC 342 is arranged so that the 1st terminal is on the lower left and a circular identifier indicating the position of the 1st terminal is formed in the vicinity of the 1st terminal, the IC 342 can be correctly arranged on the substrate. A triangular (Δ) guidance display is printed on the substrate near the circular identifier. By doing so, it is possible to prevent erroneous recognition of the mounting direction of the IC 342, and it is possible to improve workability even in confirmation after mounting. If the capacitor has polarity, a positive (+) guide sign indicating the positive electrode may be printed on the substrate near the positive electrode of the capacitor.

Further, in order to smooth the input power of the IC 342, capacitors 346 are arranged respectively. As described above, one or a plurality of electric components may be arranged in association with each other in the IC 342. When arranging the capacitor 346 on the IC 342, it is necessary to bring the capacitor 346 as close to the IC 342 as possible in order to smooth the input power.

Therefore, in the main control board 300, when a capacitor 346 is arranged in the vicinity of the IC 342 and the IC 342 and the capacitor 346 are regarded as one unit (observed integrally), one unit of long side x short side Place the capacitor 346 in a position and orientation that reduces the area. For example, in the example of FIG. 4, the longitudinal direction of the capacitor 346 is arranged along the lateral direction of the IC 342. Here, the lengths of the long side of the capacitor 346 and the short side of the IC 342 are close to each other (including the fact that the lengths are equal), and even if the longitudinal direction of the capacitor 346 is arranged along the lateral direction of the IC 342. The rectangular shape can be roughly maintained, and the area thereof is also the short side of the IC 342 × (the long side of the IC 342 + the short side of the capacitor), so that the occupied area can be reduced.

Further, in IC 342, power supply terminals having different polarities are often arranged on two longitudinal side surfaces of the main body (for example, in IC 342, the positive electrode is the 20th terminal and the negative electrode is the 10th terminal). Therefore, by arranging the longitudinal direction of the capacitor 346 along the lateral direction of the IC 342, the connection between the power supply terminals having different polarities and both terminals of the capacitor 346 can be made the shortest, and the wiring pattern can be minimized. Can also be minimized.

Here, an example of associating one capacitor 346 with one IC 342 has been described, but not limited to this case, a plurality of electric components (resistance 344, capacitor 346, conductance) with respect to one IC 342. May be associated with. In this case, it is preferable to juxtapose the plurality of electric components so that the longitudinal directions are parallel to each other, and arrange all the electrical components along the lateral direction of the IC 342. Further, here, an example of associating one capacitor 346 with one IC 342 path has been described, but the type and number of electric parts are not limited.

Further, when a plurality of (for example, two) electric parts are associated with one IC 342, the plurality of electric parts are arranged in series so that their longitudinal directions are equal to each other, and the longitudinal directions of the plurality of electric parts are set to the IC 342. It may be arranged along the longitudinal direction of. Here, the length of the long side when a plurality of electric parts are arranged in series and the length of the long side of the IC 342 are approximate (including the same length), and the longitudinal direction of the plurality of electric components is the longitudinal direction of the IC 342. Even if it is arranged along the direction, the rectangular shape can be roughly maintained, and the area is also the long side of the IC342 x (the short side of the IC342 + the short side of the electrical component), so it is possible to reduce the occupied area. Become.

Further, in the substrate of FIG. 4, a resistor group in which a plurality of resistors 344 (here, nine) are provided as pull-up resistors and pull-down resistors may be arranged with respect to the IC 342. In this case as well, in order to fully utilize the functions of the pull-up resistor and the pull-down resistor, it is necessary to bring the resistance group as close to the IC 342 as possible.

Therefore, in the example of FIG. 4, when a plurality of resistors 344 are arranged in the vicinity of the IC 342 (IC7) and the IC 342 and the resistance group are regarded as one unit (observed integrally), the long side of one unit is taken. × Place the resistance group at a position and posture where the area of the short side becomes small. For example, in the example of FIG. 4, the plurality of resistors 344 are juxtaposed so that the longitudinal directions are parallel to each other, and the juxtaposed directions are arranged along the longitudinal direction of the IC 342. Here, the short side of the resistor is shorter than the distance between the terminals of the IC 342, the length of the resistance group in the juxtaposed direction and the length of the long side of the IC 342 are close (including the same length), and the resistance group is juxtaposed. Even if the direction is arranged along the length of the IC 342, the rectangular shape can be roughly maintained, and the area is also the long side of the IC 342 × (the short side of the IC 342 + the long side of the resistor), so that the occupied area should be reduced. Is possible.

Further, in the IC 342, terminals having equal functions such as input / output may be continuously arranged. Therefore, by arranging the juxtaposed direction of the resistance group along the length of the IC 342, the connection between the continuous terminal of the IC 342 and one end of a plurality of resistances can be minimized, and the wiring pattern can be minimized. Can also be planned.

Here, an example of associating an electric component group having nine electric components (resistors 344) with one IC 342 has been described, but not limited to this case, the number of electric components is arbitrarily determined. be able to. Further, here, an example of associating a resistance group in which a plurality of resistors 344 are provided with one IC 342 has been described, but the type and number may not matter as long as the shapes and functions of the electric parts are the same. Further, although a resistance group having a separate resistance 344 is applied here, for example, a resistance array (aggregate resistance) in which a plurality of resistances are integrally formed by molding or the like may be applied.

Further, by reducing the occupied area as described above, the density of electric parts per unit area can be increased. However, when the density of electric components increases, it takes time to grasp the mounting position of the electric component and to confirm the mounting position after mounting, which reduces workability. Here, workability is improved by improving the distinctiveness.

For example, in the region shown by the broken line on the substrate of FIG. 4, the IC 342 and the capacitor 346 are regularly arranged. Specifically, the positions of the left short sides of the IC 342 are aligned (equalized or almost equalized) in the left-right direction in the front view. In addition, the positions of the left short sides of the IC 342 are aligned in the vertical direction (equalized or almost equalized) in the front view. In addition, the positions of the capacitors 346 are aligned in the left-right direction (equalized or almost equalized) in the front view. In addition, the positions of the capacitors 346 are aligned in the vertical direction (equalized or almost equalized) in the front view. Then, the capacitors 346 and IC 342 are arranged in order (alternately) from the left side of the front view, and their center positions are aligned in the vertical direction (equalized or almost equalized). Further, the IC 342 is associated with a capacitor 346 having the same subscript.

Here, by arranging the electric parts regularly, it is possible to predict the position of another electric part from one electric part according to the rule. Therefore, the distinctiveness is improved, it becomes easy to grasp the mounting position of the electric component and to confirm the mounting position after mounting, and the workability can be improved.

For non-polar electric components such as a resistor 344, a capacitor 346, and an inductor, there is no problem even if the two terminals are attached in either the vertical (left or right) direction. However, here, the directions are aligned (unified) between electrical components having the same function. For example, in FIG. 4, the arrangement (appearance) of the color codes of the resistance 344 and the capacitor 346 is arranged so as to be the same in the front view. With such an arrangement, it is possible to easily identify that the electric parts are equal to each other or different from each other, and it is possible to improve workability.

Further, here, an example in which the color codes of the resistors 344 or the capacitors 346 are arranged so as to be the same in all the main control boards 300 has been described, but the main control is not limited to this case. At least a part of the substrate 300 may be arranged so that the arrangement of the color codes of the plurality of electronic components is the same in the front view.

In addition, at the time of inspection of the electric element attached to the main control board 300, for example, at the time of operation inspection in the production line of the gaming machine 100, the type test of the Hotsukyo Association (Hotsukyo), which is a designated test organization of the Public Safety Commission. It is possible to improve workability at the time of inspection at the time of inspection, on-site inspection by police or the like, at the time of inspection for identifying the faulty part when the gaming machine 100 fails, and the like.

FIG. 5 is a diagram illustrating joining of electronic components on the main control board 300. In FIG. 5A, the substrate main body 340 is shown in cross section. 5 (b) is a partially enlarged view of FIG. 5 (a). Here, IC 342 will be described as an example of an electronic component, but other electronic components are also joined in the same manner.

As shown in FIG. 5A, the IC 342 is provided with a plurality of leads 356. The number of leads 356 differs for each electronic component.

Further, a through hole 358 penetrating from the front surface 340a to the back surface 340b is formed in the substrate main body 340 in order to insert the lead 356 of the IC 342. The through hole 358 is formed to have an inner diameter through which the lead 356 can be inserted. Further, in the through hole 358, copper plating extends over the inner peripheral surface in order to conduct at least one of the wiring pattern formed on the front surface 340a and the wiring pattern formed on the back surface 340b and the lead 356 of the IC 342. It is given.

Then, when the IC 342 is joined to the substrate main body 340, the IC 342 is arranged on the substrate main body 340 from the surface 340a side, and the lead 356 of the IC 342 is inserted into the through hole 358. The tip of the lead 356 inserted through the through hole 358 protrudes from the back surface 340b. After that, the conductive solder 360 is soldered to the lead 356 protruding from the back surface 340b by a flow method. As a result, the IC 342 is joined to the board main body 340, the IC 342 is fixed to the board main body 340, and the IC 342 is electrically connected to the wiring pattern formed on the main control board 300.

In the main control board 300, after all the electronic components are arranged on the surface 340a of the board body 340, that is, after the leads 356 of all the electronic components are inserted into the through holes 358, the board body 340 By immersing the back surface 340b in the molten solder, the molten solder flows between the lead 356 and the through hole 358, and the electronic component is bonded to the substrate main body 340.

By the way, as shown in FIG. 5B, the back surface 340b is covered with an insulating resist 364 while forming a wiring pattern 362. While the resist 364 covers the wiring pattern 362, it is not applied around the through hole 358 (annular).

Then, the periphery of the through hole 358 functions as a land 366 in which the wiring pattern 362 is exposed. The solder 360 joins the lead 356 to the substrate main body 340 so as to cover the land 366. As a result, the lead 356 conducts with the wiring pattern 362 via the solder 360.

FIG. 6 is a diagram illustrating a via hole 354. As shown in FIG. 6, the via hole 354 is formed by a through hole penetrating from the front surface 340a to the back surface 340b. The inner diameter of the via hole 354 is, for example, 0.2 to 0.3 mm. The via hole 354 is connected to the wiring pattern 362 provided on the front surface 340a of the substrate main body 340 and the wiring pattern 362 provided on the back surface 340b.

The via hole 354 is provided with copper plating 368 over the inner peripheral surface for conducting the wiring pattern 362 applied to the front surface 340a of the substrate main body 340 and the wiring pattern 362 applied to the back surface 340b. That is, in the via hole 354, the wiring pattern 362 applied to the front surface 340a of the substrate main body 340 and the wiring pattern 362 applied to the back surface 340b are made conductive by the copper plating 368.

Here, the via hole 354 is usually hollow. However, when the via hole 354 is hollow, the pattern width of the copper-plated 368, that is, the cross-sectional area is narrower than that of the wiring pattern 362, so that the impedance is higher than that of the wiring pattern 362. More specifically, the via hole 354 has a higher resistance than the wiring pattern 362 and has a slightly higher inductance and capacitance.

Then, in the via hole 354, the influence on the high frequency signal and the voltage drop when the current flows may occur, and the circuit operation may become unstable.

Therefore, in the main control board 300 of the present embodiment, the front surface 340a and the back surface 340b of the board main body 340 are covered with the resist 364 so that the wiring pattern 362 is exposed around (annular) the via hole 354. Then, the portion where the wiring pattern 362 is exposed functions as a land 370.

Further, the inside of the via hole 354 is filled with conductive solder 372. In the main control board 300, when the electronic components arranged on the board main body 340 are soldered by the flow method, the land 370 formed on the back surface 340b is heated by the heat of the molten solder and the copper plating 368 is formed. Is heated. Then, the melted solder adheres to the land 370 and flows into the copper plating 368 due to surface tension, and the inside of the via hole 354 is filled with the solder 372. Therefore, since the via hole 354 can be filled with the solder 372 together with the joining of the electronic components, the via hole 354 can be easily filled with the solder 372. The solder 372 may cover at least the land 370 (back surface 340b).

By filling the inside of the via hole 354 with the solder 372 in this way, the pattern width (cross-sectional area) of the via hole 354 can be made wider than the wiring pattern 362 formed on the front surface 340a and the back surface 340b of the substrate main body 340. can. As a result, the impedance of the via hole 354 can be made lower than that of the wiring pattern 362, and the stability of the circuit operation can be improved.

Ideally, all the via holes 354 provided in the main control board 300 are filled with solder 372, but even if only some of the via holes 354 are filled with solder 372, the effect of lowering the impedance is achieved. There is.

Ideally, the via hole 354 is completely filled with solder 372 from the front surface 340a to the back surface 340b, but even if only a part from the front surface 340a to the back surface 340b is filled with the solder 372, the impedance is increased. It has the effect of lowering.
