    • PURPOSE: A printed circuit board and a manufacturing method thereof are provided to prevent an open defect of a via by including a via land. CONSTITUTION: A via land(130) is separated from an inner circuit layer(120) and is arranged on a first insulation layer. A second insulation layer(140) is arranged on the first insulation layer. A first outer circuit layer(181) and a second outer circuit layer(182) are arranged on the outer sides of the first insulation layer and the second insulation layer. A via(150) passes through a hole of the via land and the first and second insulation layers. The via electrically connects the first and second outer circuit layers.
    • 目的:提供印刷电路板及其制造方法,以通过包括通孔接地来防止通孔的开放缺陷。 构成:通孔焊盘(130)与内部电路层(120)分离,并且布置在第一绝缘层上。 第二绝缘层(140)布置在第一绝缘层上。 在第一绝缘层和第二绝缘层的外侧设置有第一外部电路层(181)和第二外部电路层(182)。 通孔(150)穿过通孔焊盘的孔和第一绝缘层和第二绝缘层。 通孔电连接第一和第二外部电路层。
