- a printed wiring board in which an insulating material is filled between conductor circuits is a build-up printed wiring board.
- a conductor circuit and an interlayer resin insulation layer are alternately laminated on a core substrate, and the conductor circuit located in the lower layer and the conductor circuit located in the upper layer open the interlayer resin insulation layer.
- a gap between wiring patterns constituting each conductor circuit is filled with an interlayer insulating layer made of a dielectric, and each wiring pattern is formed so that its cross-sectional shape is substantially rectangular. ing.
- An object of the present invention is to provide a printed wiring board capable of suppressing crosstalk and signal delay even if the minimum conductor width LZ minimum interval S is miniaturized, by solving the above-mentioned problems of the prior art. is there.
- the present invention In the printed wiring board in which an insulating material is filled between conductor circuits,
- the conductor circuits are substantially trapezoidal in cross-sectional shape, and when the interval between adjacent conductor circuits is W 1 as the upper interval between the conductor circuits and W 2 as the interval between the lower sides of the conductor circuits, these conductor circuits In relation to the conductor circuit thickness T, the following equation:
- W 1— W 2 I is 0.1 when the thickness of the conductor circuit is T.
- the opposing side walls of the adjacent conductor circuits are not parallel to each other, so that the capacitor capacity between the adjacent conductor circuits can be reduced. Therefore, crosstalk and signal delay can be suppressed even if an IC that is driven at high speed is installed.
- the cross-sectional shape of the conductor circuit is substantially trapezoidal J is not only that the corner on the upper side of the conductor circuit is recognized as a geometric acute angle or obtuse angle, but is slightly rounded. If it has a rounded shape, or if the hypotenuse of the conductor circuit is slightly curved rather than straight, if the top surface of the conductor circuit is slightly rounded overall, or on the top and / or slope of the conductor circuit This also includes the case where a roughened surface consisting of irregular irregularities is formed, meaning that the cross-sectional shape of the conductor circuit is visually recognized as a trapezoid rather than a rectangle.
- the conductor circuit is preferably formed by an additive method (full additive method, semi-additive method), and can also be formed by vapor deposition or the like.

- the conductor circuit formed by such a method is formed by etching away the metal layer exposed in the portion where the etching resist is not formed, but not only in the direction perpendicular to the surface of the substrate but also in the horizontal direction. Since the direction is also etched, the cross-sectional area of the conductor circuit is reduced. As a result, the conductor resistance becomes higher compared to the conductor circuit formed by the additive method.
- the “conductor circuit upper interval W1” is defined as the distance between the upper ends of adjacent conductor circuits when the corner on the conductor circuit upper side is recognized as a geometrical acute angle or obtuse angle.
- the conductor circuit lower interval W2 is defined as the distance between the lower end portions of two opposite hypotenuses in the vertical cross-section of adjacent conductor circuits.
- W1 is an extension line of two straight sides of the opposite hypotenuse and a straight portion of the upper side in the vertical cross section of the conductor circuit adjacent to each other.

- the printed wiring board according to the present invention is a printed wiring board in which an insulating material is filled between conductor circuits, and each conductor circuit has a substantially trapezoidal cross-sectional shape, as shown in FIG.
- W 1 for the upper distance of the conductor circuit
- W 2 for the distance of the lower surface of the conductor circuit-these distances in relation to the thickness T of the conductor circuit are 0. 1 OT ⁇ IW 1— W 2 I ⁇ 0. 7 3
- the reason why the thickness ⁇ of the conductor circuit is included in such a relational expression is that the thickness ⁇ of the conductor circuit affects the capacitor capacity between adjacent conductor circuits. If the opposing side walls of adjacent conductor circuits are not parallel but are facing diagonally, the conductor circuit The capacitance of the capacitor is reduced compared to the case where the opposite side walls are parallel.
- the preferable range of W1 -W2 I is 0.35 T to 0.73 mm, and the optimal range is 0.10 mm to 0.35 mm. This is because, within this range, a sufficient conductor volume can be secured even with a conductor circuit of L / S-1 2.5 / 12.5 m or less. In addition, the capacitor capacity between the conductor circuits is also reduced. In the present invention, the LZS of the conductor circuit is more significant in that the finer one has a larger capacitor capacity (capacitance) between the conductor circuits, but 5/5 ⁇ m to 15 5 15 A range is preferred.
- the thickness of the conductor circuit is preferably 5 to 25 m. The reason is that if the thickness is less than 5 ⁇ m, the electrical resistance value of the conductor circuit is large, while if it exceeds 25 / m, the capacitor capacity increases, which is disadvantageous for high-speed signal transmission. This is because if an IC chip of 6 GHz or higher is mounted, malfunctions are likely to occur.
- a printed wiring board includes a plurality of products, for example, a 340X51 Omm size, but in the present invention, I W1 -W2 I within one product (equal to one product)
- the data is divided into 4 parts, and 8 data randomly extracted from each divided area (2 data is extracted from each divided area) is represented by the standard deviation ⁇ . (0. 04 ⁇ + 2) below is preferred.
- the transmission speed of each signal line is constant, so there is no difference in transmission speed between the signal lines.
- a malfunction occurs with a large difference in transmission speed between signal lines.
- a roughened surface is formed on at least the side wall of the conductor circuit.
- the presence of a roughened surface significantly increases the surface area of the conductor circuit side wall. Accordingly, the capacitance of the capacitor between the conductor circuits also increases. Therefore, applying the present invention to a printed wiring board having a roughened surface on the side wall of the conductor circuit has a great effect.
- the roughened surface is not particularly limited, and can be formed by etching such as blackening, interplate, or Cz treatment.
- the trapezoidal area connecting the four vertices A, ⁇ , C, and D in the cross section of the conductor circuit is also represented by S in the conductor circuit formed by the additive method, as schematically shown in Fig. 11. . If the cross-sectional area of the conductor circuit is S, 0.

- the reason is that if the thickness is less than 1 O jli m, the electric resistance of the conductor is too large to supply power instantaneously when the IC voltage drops, i.e., it cannot return instantaneously to the IC drive voltage, on the other hand, This is because if the thickness exceeds 2500 m, the thickness of the interlayer insulating layer will not be uniform due to the unevenness of the circuit forming part and the circuit non-forming part.
