Abstract

一种印刷电路板，其包括一信号层及一电源层，该信号层包括一流有振荡电流的连接区块，该电源层处于该信号层下侧，该电源层对应该连接区块设有一防止该连接区块的振荡电流干扰该电源层的隔离区块。该印刷电路板能防止信号层的振荡电流对电源层的干扰。

Description

印刷电路板
技术领域
本实用新型涉及一种印刷电路板，特别是关于一种可防止信号层的振荡电流干扰电源层的印刷电路板。
背景技术
如图1所示，现有的印刷电路板10包括一信号层11、一电源层12及一接地层13。该信号层11处于该电源层12之上，该信号层11包括一连接区块112及一安置在该连接区块112上的开关元件111。该电源层12处于该接地层13之上，为了提供多个不同电压电源，该电源层被若干切割线隔成若干电压区域121、122、123，该连接区块112及该开关元件111处于该电压区域122正上方。
当该开关元件111处于工作状态时，其接受的为脉冲信号，该开关元件111在脉冲信号的影响下，不断地开通及闭合，造成流经该连接区块112的电流为振荡电流，使该连接区块112正下方的电压区域122的电压波动，从而影响该电压区域122的电压稳定性。
发明内容
鉴于以上内容，有必要提供一种可防止信号层的电流干扰电源层的印刷电路板。
一种印刷电路板，其包括一信号层及一电源层，该信号层包括一流有振荡电流的连接区块，该电源层处于该信号层下侧，该电源层对应该连接区块设有一防止该连接区块的振荡电流干扰该电源层的隔离区块。
相较于现有技术，所述印刷电路板的电源层对应该连接区块设有一隔离区块，当该连接区块中有振荡电流时，其产生的振荡干扰不会影响到电源层的电压。该印刷电路板能防止信号层的振荡电流对电源层的干扰。
附图说明
下面参照附图结合实施方式对本实用新型作进一步的描述。
图1是现有的印刷电路板分解示意图。
图2是本实用新型较佳实施例印刷电路板分解示意图。
图3是本实用新型较佳实施例印刷电路板正视图。
具体实施方式
请参阅图2，本实用新型较佳实施例印刷电路板20包括一信号层21、一电源层22及一接地层23。
该信号层21处于该电源层22之上，该信号层21包括一连接区块212及一布置在该连接区块212上的开关元件211。在本实施例中，该开关元件211为一MOS管。
该电源层22处于该接地层23之上，该电源层22被若干切割线隔离成若干电压区域221、222、223，该连接区块212及该开关元件211处于该电压区域222正上方，在该电压区域222中，该电源层22在该开关元件211的正下方设有一隔离区块224，该隔离区块224由一切割线225围绕而成，该切割线225将该电源层22以一定的宽度切割形成该隔离区块224，从而使该隔离区块224与该电压区域222无电性连接关系。
请一并参阅图2及图3，该连接区块212的正投影处在该隔离区块224中。当该开关元件211处于工作状态时，其接受的为脉冲信号，该开关元件211在脉冲信号的影响下，不断地开通及闭合，造成流经该连接区块212的电流为振荡电流，该连接区块212处于该电源层22的电压区域222的隔离区块224中，该振荡电流的干扰只影响该电源层22的隔离区块224，而隔离区块224与该电压区域222隔开，从而避免了该振荡电流影响到该电压区域222的电压稳定性。
在上述实施例中，该开关元件211可为其它接收脉冲信号的电子元件。该隔离区块224可与该连接区块212连接起来，有助于该连接区块212散热。可将接地层23对应于该电源层22的隔离区块224的区域以隔离线分割一隔离区块，防止接地层受到该开关元件211在工作状态时带来的干扰。
