    • To provide a method for manufacturing a printed wiring board which can easily and surely form a fine wiring pattern having a small layer thickness while enhancing the productivity by simplifying a process, when forming a wiring structure having a filled via. The method for manufacturing a printed wiring board according to the present invention includes: bonding a metal foil 20 provided with a carrier foil having a carrier foil layer 22 and a metal foil layer 21 onto a resin substrate 11 (insulator) so that the metal foil layer 21 can contact one surface of the resin substrate 11; subsequently forming a via hole V (connection hole); filling the via with a film 32 formed by plating; then peeling the carrier foil layer 22 of the metal foil 20 provided with the carrier foil from the metal foil layer 21; and patterning the metal foil layer 21 which remains on the resin substrate 11 in a bonded state to form a wiring pattern 23.
    • 提供一种制造印刷电路板的方法,其可以容易且可靠地形成具有小层厚度的精细布线图案,同时通过简化工艺来提高生产率,当形成具有填充通孔的布线结构时。 根据本发明的制造印刷电路板的方法包括:将具有载体箔层22和金属箔层21的载体箔的金属箔20接合到树脂基板11(绝缘体)上,使得金属箔 层21可以接触树脂基板11的一个表面; 随后形成通孔V(连接孔); 用通过电镀形成的膜32填充通孔; 然后从金属箔层21剥离设置有载体箔的金属箔20的载体箔层22; 并且在接合状态下图案化保留在树脂基板11上的金属箔层21,以形成布线图案23。

    • In a portable data erasing device, to prevent data leaks from magnetic disk devices to be disposed, data is erased by a simple operation. The data erasing device using a magnetic field generated by permanent magnets to erase data comprises a sliding tray, a main body and a swinging tray. The sliding tray is movable into and out from the main body, two permanent magnets, adjacently arranged so that the north and south poles thereof have mutually attracting polarities, are attached to the front end of the sliding tray. One end of the swinging tray is fixed to the upper surface of the main body by a shaft, so that a magnetic disk device can be mounted and swung on top of the main body. While the sliding tray is extracted stepwise from the main body, the magnetic disk device can be swung, and data on the magnetic disks erased.
    • 在便携式数据擦除装置中,为了防止数据从磁盘装置泄漏出来,通过简单的操作来擦除数据。 使用由永磁体产生的磁场来擦除数据的数据擦除装置包括滑动托盘,主体和摆动托盘。 滑动托盘可移动进入主体和从主体移出,两个永磁体相邻地布置成使得其南极和南极具有相互吸引的极性,附接到滑动托盘的前端。 摆动托盘的一端通过轴固定在主体的上表面,从而可以在主体的顶部上安装和摆动磁盘装置。 当滑动托盘从主体逐步抽出时,磁盘装置可以摆动,并且磁盘上的数据被擦除。
