Description

印刷电路板
【技术领域】
本发明涉及一种印刷电路板，特别涉及一种对不同接口的针脚孔共同布线(layout)的印刷电路板。
【背景技术】
由于规范更新换代和技术的不断改进，为了满足不同厂商对接口的需求，同时有效的节省布线空间，在对印刷电路板进行布线设计时会考虑对不同的接口的针脚孔采用共同布线。针脚孔是设置在印刷电路板上的孔，接口零件的针脚可插入并焊接于其内，以实现接口器件与印刷电路板上对应信号线间的电气连接。
比如，目前计算机主要采用两种串行外设接口—USB(Universal SerialBus，通用串行总线)接口和IEEE(The Institute of Electrical and ElectronicsEngineers，电机电子工程师协会)1394接口，此两串行外设接口均集成于印刷电路板上。USB接口是一种计算机系统与外围设备连接的输入/输出接口。USB接口通过一个4针脚的标准插头，采用菊花链形式把所有的外设连接起来。IEEE 1394接口是一具有视频数据传输速度的串行接口，它是将PC和消费类电器连接起来的重要桥梁。目前，IEEE 1394接口广泛应用于数字成像领域，是唯一支持数字摄录机的总线接口。随着用户需求的不断提高，USB接口和IEEE 1394接口将同时提供不同的服务以共同处理所有外部输入输出。
请参阅图1至图3，印刷电路板上IEEE 1394接口的安装区10中A区的针脚孔与图2中USB接口的安装区20中B区的针脚孔的布局完全对应，如IEEE1394接口的针脚孔12与USB接口针脚孔22对应。故在印刷电路板布线设计时，可以对A区及B区进行共同布线，即在印刷电路板布线时，把A区及B区对应的针脚孔重叠，以节省布线空间。
请继续参阅图4，在设计过程中，理想情况下A区IEEE 1394接口的针脚孔12的中心点O1与B区USB接口的对应针脚孔22的中心点O2应该完全重合于一点，相应的信号线40将连接至该重合点以同时完成不同接口的电气连接。但是由于设计工具存在误差，所以上述两针脚孔12、22的中心点O1、O2不能完全重合。如果所述信号线40接至IEEE 1394接口的针脚孔12的中心点O1，则USB接口工作时信号传输将会出现断路；同理，如果所述信号线40接至USB接口的针脚孔22的中心点O2，则IEEE 1394接口工作时信号传输将会出现断路；从而影响了整个印刷电路板的工作稳定性。故设计过程中必须花费大量时间分析和解决所述断路问题，以使上述两接口接入时均可正常工作，从而浪费了人力并将浪费大量时间。
【发明内容】
鉴于以上内容，有必要提供一种可满足共同布线针脚孔的不同接口同时正常工作的印刷电路板。
一种印刷电路板，包括一第一接口的针脚孔、一第二接口的针脚孔及一信号线，所述第一接口的针脚孔及第二接口的针脚孔重叠；所述信号线对应电气连接至所述第一接口的针脚孔的中心点或所述第二接口的针脚孔的中心点；所述重叠的两针脚孔之间由铜箔进行导通。
相较现有技术，本发明所述两重叠的针脚孔之间由铜箔进行导通，从而使得每一重叠的针脚孔的中心点与所述印刷电路板上的信号线连接，减少了设计时的排错分析及验证改进过程，提高了设计效率。
【附图说明】
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。
图1是现有印刷电路板上IEEE 1394接口的安装区的示意图。
图2是现有印刷电路板上USB接口的安装区的示意图。
图3是现有印刷电路板上IEEE 1394接口及USB接口共同布线的示意图。
图4是现有技术中IEEE 1394接口及USB接口共同布线的针脚孔的放大示意图。
图5是本发明印刷电路板的较佳实施方式的部分共同布线的针脚孔的放大示意图。
【具体实施方式】
请参阅图5，本发明印刷电路板的较佳实施方式以印刷电路板上IEEE1394接口和USB接口对应的针脚孔来加以说明。所述印刷电路板包括两信号层(图未标示)、若干IEEE 1394接口的针脚孔、若干USB接口的针脚孔及若干信号线。所述IEEE 1394接口的针脚孔及USB接口的针脚孔布局相同的部分采用共同布线。所述信号线对应电气连接至所述IEEE 1394接口的针脚孔的中心点或所述USB接口的针脚孔的中心点。
如图示，IEEE 1394接口的针脚孔52与对应USB接口的针脚孔54采用共同布线，即两者重叠设计。所述IEEE 1394接口的针脚孔52及USB接口的针脚孔54均贯穿所述印刷电路板，其中所述IEEE 1394接口的针脚孔52的中心点为A1，所述USB接口的针脚孔54的中心点为A2。所述信号线56电气连接至所述IEEE 1394接口的针脚孔52的中心点A1或USB接口的针脚孔54的中心点A2。如果所述信号线56连接至所述IEEE 1394接口的针脚孔52的中心点A1，则IEEE 1394接口器件的针脚与所述印刷电路板上的对应信号线56实现电性连接；如果所述信号线56连接至所述USB接口的针脚孔54的中心点A2，则USB接口器件的针脚与所述印刷电路板上的对应信号线56实现电性连接。
在IEEE 1394接口的针脚孔52与USB接口的针脚孔54共同布线时，理论上所述IEEE 1394接口的针脚孔52的中心点A1与USB接口的针脚孔54的中心点A2应该重合于一点，但在印刷电路板布线设计时，由于设计工具恒存在误差，故A1、A2不可能重合。故，本较佳实施方式中，将所述IEEE 1394接口的针脚孔52与USB接口的针脚孔54之间通过铜箔58来进行导通。所述铜箔58位于所述印刷电路板的上层信号层。由于在印刷电路板工艺制造过程中，针脚孔会吸铜，从而可使两针脚孔的中心点A1和A2之间恒电气连接，从而可使所述信号线56同时与所述IEEE 1394接口的针脚孔52的中心点A1及USB接口的针脚孔54的中心点A2都电气相连，达到了设计目的，提高了整个印刷电路板的质量和稳定性。
由于上述IEEE 1394接口的针脚孔52及USB接口的针脚孔54共同布线，所以按照该方法设计的印刷电路板的同一外设接口既可以使用IEEE 1394接口设备，也可使用USB接口设备，更好的满足了不同客户的要求。
同理，对于可共同布线的其它不同接口的针脚孔，也可应用上述方法来设计。
