    • A flexible cable is provided in which a transmission characteristic can be ensured in a high frequency band, and electromagnetic noises can be suppressed. A flexible cable 11 includes a sheet-like base member (dielectric substance) 1; an adhesive (dielectric substance) 2 which bonds the base member 1 to a cover member (dielectric substance) 3; a shield member 4 which covers the cover member 3 and is bonded or printed to the cover member 3 to suppress electromagnetic noises to be radiated; and a top coating member 5 which covers the shield member 4 to protect the shield member 4. The flexible cable 11 has a differential signal wire group 7 including differential signal wires 6 through which differential signals pass and guard ground wires 9a which prevent the interference from other differential signals; a low-speed signal wire 8 through which a low-speed signal passes; a ground wire 9 used as a ground; and a shield ground wire 10 which is adapted to allow the electric potential of the shield member 4 to be identical to the electric potential of the ground, all of which are provided in the adhesive 2. The differential signal wires 6 are not covered with the shield member 4.
    • 提供一种柔性电缆,其中可以在高频带中确保传输特性,并且可以抑制电磁噪声。 挠性电缆11包括片状基体(电介质)1; 将基材1与盖部件(电介质)3接合的粘合剂(电介质)2; 遮盖构件4,其覆盖盖构件3,并且被接合或印刷到盖构件3,以抑制要辐射的电磁噪声; 以及覆盖屏蔽构件4以保护屏蔽构件4的顶部涂覆构件5.柔性电缆11具有差分信号线组7,差分信号线组7包括差分信号通过的差分信号线6,并且防止接地线9a防止干扰 其他差分信号; 低速信号通过的低速信号线8; 用作地面的地线9; 以及屏蔽接地线10,其适于允许屏蔽构件4的电位与地面的电位相同,所有这些都设置在粘合剂2中。差分信号线6不被覆盖 屏蔽构件4。

    • A printed wiring board in which an opening existing around a pad which is a photovia land is arranged so that it is not overlapped with the pad, the area of an opening existing around a pad and that of another opening are equalized, the quantity of resin which is filled in each opening or is equalized throughout a printed wiring board and the quantity of resin overflowing from each opening or when resin is filled in each opening or is uniformed is provided. According to such a printed wiring board, a reliable printed wiring board wherein secure connection is enabled without causing disconnection can be realized when a circuit pattern provided on an interlayer insulating board formed on the printed wiring board and a conductor pad are connected by arranging an opening existing around a conductor pad so that it is not overlapped with the conductor pad and substantially equalizing the quantity of resin which is filled in an opening around a conductor pad and that of resin which is filled in another opening.
    • 本发明提供一种印刷线路板,该印刷线路板中,在作为光电晶体管的焊盘周围存在的开口以不与焊盘重叠的方式配置,焊盘周围的开口部的面积与其他开口的面积相等, 其填充在每个开口中或者在整个印刷线路板中均匀化,并且提供从每个开口溢出的树脂量,或者当树脂被填充在每个开口中或者被均匀化时。 根据这样的印刷布线板,当在印刷布线板上形成的层间绝缘板上提供的电路图案和导体焊盘通过布置开口而连接时,可以实现可靠的印刷布线板,其中可靠地连接而不会导致断开 存在于导体焊盘周围,使得其不与导体焊盘重叠并且实质上均衡填充在导体焊盘周围的开口中的树脂量和填充在另一个开口中的树脂量。
