具体实施方式 Detailed ways

[0022] 下面结合附图及较佳实施方式对本发明作进一步详细描述: [0022] The present invention will be described in further detail in conjunction with the accompanying drawings and preferred embodiments:

[0023] 请参考图2,本发明印刷电路板的较佳实施方式包括一顶层11 (其它层图中未示),该顶层11上设置有一内存控制器12。 [0023] Referring to FIG. 2, the preferred embodiment of the present invention is a printed circuit board 11 includes a top layer (not shown in FIG other layers), the top layer 12 is provided with a memory controller 11. 当然,诸如显卡插槽、中央处理器插槽等组件亦设置于顶层11上,图1中并未示出。 Of course, such as a card slot assembly, the central processor slot, are also provided on the top layer 11, not shown in FIG. 1. 本实施方式中,该印刷电路板为一主板10。 In the present embodiment, the printed circuit board 10 is a motherboard.

[0024] 该主板10包括一第一缺15及一第二缺25,该第一缺15的长度与一第一内存16 的长度相当,该第二缺25的长度与一第二内存沈的长度相当。 [0024] The main board 10 includes a first 15 and a second missing missing 25, missing the first length 15 and the length of a first memory 16 rather, the lack of a second length 25 and a second memory sink considerable length. 该主板10于第一缺15及第二缺25处分别设置有若干金手指18及观,该若干金手指18及观通过对应的迹线与内存控制器12电连接。 The board 10 and the second to the first missing missing 15 respectively provided at a plurality of gold fingers 25 and 18 concept, the concept of a plurality of gold fingers 18 and electrically connected by corresponding trace with the memory controller 12.

[0025] 请参考图3,一第一连接器19的第一端用于容纳第一缺15处的若干金手指18,第二端用于容纳第一内存16的若干金手指17。 [0025] Please refer to FIG. 3, a first end of a first connector 19 for receiving a first plurality of golden fingers 15 missing at 18, a second end 17 for receiving a plurality of gold fingers of the first memory 16. 本实施方式中,该第一连接器19可利用两个现有的内存插槽190及192连接而成,其中第一内存插槽190用于容纳第一缺15处的若干金手指18,第二内存插槽192则用于容纳第一内存16的若干金手指17。 In the present embodiment, the first connector 19 may utilize two conventional memory slots 190 and 192 connected to each other, wherein the first plurality of memory slots 190 for receiving a first missing Goldfinger 15 at 18, two memory slots 192 for receiving a plurality of gold fingers 17 of the first memory 16. 由于两内存插槽190及192电连接,故内存控制器12即可通过第一缺口15处的金手指18以及第一连接器19与第一内存16之间互相通讯。 Since the two memory slots 190 and 192 are electrically connected, so that the memory controller 12 to communicate with each other between the first 19 and the memory 16 through a first notch 15 at the golden finger 18 and the first connector. 且当第一内存16插入到第二内存插槽192时,该第一内存16的板体与该主板10的板体平行。 And when the first memory 16 into second memory slot 192, the plate 16 is parallel to the first memory board 10 of the board.

[0026] 同理,一第二连接器四的第一端用于容纳第二缺口25处的若干金手指观,第二端用于容纳第二内存26的若干金手指27,且当第二内存沈插入到第二连接器四的第二端时,该第二内存26的板体与该主板10的板体平行。 [0026] Similarly, a second connector terminal for receiving a first four of the second plurality of notches 25 Goldfinger View second end for receiving a second plurality of memory Goldfinger 2726, and when the second memory sink inserted into the second end of the second four connectors, the second memory board 26 is parallel to the board plate 10. 如此一来即可使得主板10在插上第一内存16及第二内存沈后厚度基本不变,且还可以根据需要安装不同容量的内存。 Such that the motherboard 10 can result in a plug in the first memory and the second memory 16 Shen substantially constant thickness, and can also install a different capacity of memory needed. 另外,第一内存16及第二内存沈还组成双内存通道,以使得内存的带宽增加一倍。 Further, the first memory and the second memory 16 composed of dual sink further memory channels, so that the memory bandwidth doubled.

[0027] 另外,主机板10的顶层11上,第一缺口15处的金手指18到内存控制器12之间的距离与第二缺口25处的金手指观到内存控制器12之间的距离相等。 [0027] In addition, the top layer 10 on the motherboard 11, a first notch at a Goldfinger 1518 to the distance between the memory controller 12 to the finger 25 at a second distance between the notch 12 View memory controller equal. 如此,由于两缺口处的金手指18及观与内存控制器12之间的距离相等,故在设计包括双通道内存插槽的印刷电路板时,第一缺口15处的金手指18与第二缺口25处的金手指28到内存控制器12之间的迹线可采用相同的布线长度及规则,不仅简化了设计的复杂度,亦减少了设计人员的负担与失误。 Thus, due to the equal distance between the two notches at the Goldfinger View 18 and memory controller 12 and, when it is designed as dual-channel memory slots of a printed circuit board, finger at the first and the second notch 1518 Goldfinger 28 at notch 25 to the memory controller 12 may be employed between the traces of the wiring length and the same rule, not only simplifies the complexity of the design, and also reduces the burden on the designer's mistakes. 本实施方式中,金手指18及观到内存控制器12之间的距离可以金手指18 及28的中心点到内存控制器12的中心点为准。 In the present embodiment, finger 18 and the distance between the concept of the memory controller 12 can cheat the center point 18 and 28 to the center point of whichever memory controller 12.
