    • PURPOSE: A manufacturing method of a PCB is provided to form micro-pattern by forming a circuit pattern using an additive mode. CONSTITUTION: A core substrate having a metal layer is prepared in both sides of an insulating layer(S100). A via hole is formed in both sides of a core substrate(S200). A process forming the via hole comprises a step of opening one side of the via hole and a step of blocking up the other side of the via hole with a metal layer. A seed layer is formed in the via hole(S300). A plating resist having an opening is formed in both sides of the core substrate(S400). The via and a circuit pattern are formed by a predetermined plating method(S500). The plating resist is removed. The seed layer and the metal layer revealed in the surface are removed(S600).
    • 目的:通过使用添加模式形成电路图案,提供PCB的制造方法以形成微图案。 构成:在绝缘层的两侧制备具有金属层的芯基板(S100)。 在芯基板的两侧形成通孔(S200)。 形成通孔的工艺包括打开通孔的一侧的步骤和用金属层封闭通孔的另一侧的步骤。 在通孔中形成种子层(S300)。 在芯基板的两侧形成具有开口的电镀抗蚀剂(S400)。 通孔和电路图案通过预定的电镀方法形成(S500)。 去除电镀抗蚀剂。 去除在表面露出的种子层和金属层(S600)。

    • PURPOSE: A printed wiring board is provided to lowly suppress a thermal expansion rate by laying a glass fiber cloth in an insulation layer of a buildup layer. CONSTITUTION: A printed wiring board(11) includes a carbon fiber. The printed wiring board includes a core substrate with intensity to maintain a shape with a single body. A plurality of buildup layers(26,27) are successively formed on the core substrate. The buildup layer is comprised of the laminate of a plurality of insulation layers(28) and conductive wiring layers(29). The insulation layer is made of resin material impregnated to the fiber. The thermal expansion rate is lowly suppressed in the buildup layer based on the fiber. The thermal expansion rate is lowly suppressed in the core substrate based on the carbon fiber. The thermal expansion rate of the buildup layer is controlled according to the thermal expansion rate of the core substrate. The crack is prevented inside the buildup layer. The disconnection of the conductive wiring layer is prevented.
    • 目的:提供一种印刷电路板,通过将玻璃纤维布铺放在堆积层的绝缘层中来低压抑制热膨胀率。 构成:印刷电路板(11)包括碳纤维。 印刷电路板包括具有强度以单体保持形状的芯基板。 多个堆积层(26,27)依次形成在芯基板上。 堆积层由多个绝缘层(28)和导电布线层(29)的叠层构成。 绝缘层由浸渍在纤维中的树脂材料制成。 在基于纤维的堆积层中,热膨胀率被低抑制。 在基于碳纤维的芯基板中,热膨胀率低。 堆积层的热膨胀率根据芯基板的热膨胀率进行控制。 裂缝在堆积层内被阻止。 防止了导电布线层的断开。
