    • A printed circuit board (PCB) includes a top layer, a memory controller, two gaps, and two connectors. The memory controller is located on the top layer. A number of golden fingers are respectively set on the top layer near each gap and electrically connected to the memory controller. Each connector includes a first slot to hold the gold fingers near a corresponding one of the gaps and a second slot to hold a number of gold fingers of a corresponding one of two memory chips. The first slot is electrically connected to the second slot. Each memory chip and the PCB are coplanar.
    • 印刷电路板(PCB)包括顶层,存储器控制器,两个间隙和两个连接器。 内存控制器位于顶层。 多个金手指分别设置在每个间隙附近的顶层上并电连接到存储器控制器。 每个连接器包括用于将金手指保持在相应的一个间隙附近的第一槽和用于保持两个存储器芯片中对应的一个的多个金手指的第二槽。 第一槽电连接到第二槽。 每个存储芯片和PCB都是共面的。

    • A printed circuit board (PCB) includes first and second signal layers. First and second pairs of signal transmission lines are respectively laid out on the first and second signal layers. The first pair of signal transmission lines includes first positive and negative differential signal transmission lines. The second pair of signal transmission lines includes second positive and negative differential signal transmission lines. The first positive differential signal transmission line is electrically connected to the second negative differential signal transmission line by a first vertical interconnect access (via). The first negative differential signal transmission line is electrically connected to the second positive differential signal transmission line by a second via. An angle between a centerline of each of the first via and second via and a surface of the PCB is an acute angle.
    • 印刷电路板(PCB)包括第一和第二信号层。 第一和第二对信号传输线分别布置在第一和第二信号层上。 第一对信号传输线包括第一正和负差分信号传输线。 第二对信号传输线包括第二正和负差分信号传输线。 第一正差分信号传输线通过第一垂直互连接入(via)与第二负差分信号传输线电连接。 第一负差分信号传输线通过第二通孔电连接到第二正差分信号传输线。 第一通孔和第二通孔中的每一个的中心线与PCB的表面之间的角度是锐角。
