    • A method for manufacturing a printed wiring board including providing an insulating resin substrate having first and second surfaces, irradiating laser upon the first surface such that a first opening portion having an opening on the first surface and tapering inward is formed, irradiating laser upon the second surface such that a second opening portion having an opening on the second surface, tapering inward and communicated to the first opening portion is formed and that a penetrating-hole having the first and second opening portions is formed, forming an electroless plated film on an inner wall surface of the penetrating-hole, and forming an electrolytic plated film on the electroless plated film such that a through hole conductor structure is formed in the penetrating-hole. The opening of the first portion has an axis of the center of gravity offset with respect to that of the opening of the second opening portion.
    • 一种制造印刷电路板的方法,包括:提供具有第一和第二表面的绝缘树脂基板,在第一表面上照射激光,使得形成在第一表面上具有开口并向内逐渐变细的第一开口部分,在第二表面上照射激光 形成第二开口部,该第二开口部在第二面上形成有向内侧逐渐变细并且与第一开口部连通的第二开口部,形成有具有第一开口部和第二开口部的贯通孔,在内部形成无电解电镀膜 并且在所述化学镀膜上形成电解镀膜,使得在所述贯通孔中形成贯通孔导体结构。 第一部分的开口具有相对于第二开口部分的开口偏心的重心轴线。

    • A printed wiring board has an insulating resin substrate having a first surface and a second surface, the insulating resin substrate having one or more penetrating-holes passing through the insulating resin substrate from the first surface to the second surface, a first conductor formed on the first surface of the insulating resin substrate, a second conductor formed on the second surface of the insulating resin substrate, and a through-hole conductor structure formed in the penetrating-hole of the insulating resin substrate and electrically connecting the first conductor and the second conductor. The penetrating-hole has a first portion having an opening on the first surface and a second portion having an opening on the second surface. The first portion and the second portion are connected such that the first portion and the second portion are set off from each other.
    • 印刷电路板具有具有第一表面和第二表面的绝缘树脂基板,所述绝缘树脂基板具有从所述第一表面到所述第二表面穿过所述绝缘树脂基板的一个或多个贯穿孔,形成在所述绝缘树脂基板上的第一导体 绝缘树脂基板的第一表面,形成在绝缘树脂基板的第二表面上的第二导体和形成在绝缘树脂基板的穿透孔中的通孔导体结构,并将第一导体和第二导体 。 所述贯穿孔具有在所述第一表面上具有开口的第一部分和在所述第二表面上具有开口的第二部分。 第一部分和第二部分被连接成使得第一部分和第二部分彼此脱离。
