用protel设计四层板的实例过程及内电层分割
--------------------------------------------------------------------------------
本教程将详细的讲解Protel99SE的四层板的设计过程,以及在其中的内电层分割的用法。
事先声明:
本教程用于初学者的入门与提高;对于高手们,也欢迎看看,帮小弟指出其中不当的做法~
下面,就打开你的电脑及软件开始了。
(------好像是废话,嘿嘿.....)一、准备工作
新建一个DDB文件,再新建相关的原理图文件,并做好相关准备设计PCB的准备工作,这个相信想画四层板的朋友都会,不用我多讲了。
二、新建文件
新建一个PCB文件,在KeepOutLayer层画出PCB的外框,如下图,用过Protel的朋友们应该都会。
三、设置板层
在PCB界面中点击主菜单Design再点击LayerStackManager如图:
点击后弹出下面的层管理器对话框,因为在Protel中默认是双面板,所以,我们看到的布线层只有两层。

现在我们来添加层,先单击左边的TopLayer,再单击层管理器右上角的AddPlane按钮,添加内电层,这里说明一下,因为现在讲的是用负片画法的四层板,所以,需要添加内电层,而不是AddLayer。
单击后,将在TopLayer的下自动增加一个层,双击该层,我们就可以编辑这一层的相关属性,如下图:
在Name对应的项中,填入VCC,点击确定关闭对话框,也就是将该层改名为VCC,作为设计时的电源层。
按同样的方法,再添加一个GND层。
完成后如图:
四、导入网络

回到原理图的界面,单击主菜单Design==>UpdatePCB如图:

选择要更新的PCB文件,点击Apply,

再点击左边的,查看我们在原理图中所做的设计是否正确。
这里,我们把项打上勾,只查看错误的网络。

在这里,我们没有发现有任何错误网络时,可以单击将网络导入PCB文件了。
这种导入网络的方法是Protel的原理图导入网络到PCB的一个很方便的方法,不用再
去生成网络表了。
同时,修改原理图后的文件,也可用此方法快速更新PCB文件。
五、布局
由于这个基本大家都会,所以省略了,完成后如图
:

六、设置内电层
我们再执行主菜单Design下的LayerStackManager弹出层管理器,
双击VCC层,在弹出的对话框中,在Netname的下拉对话框中选择VCC网络,给这一层真正定义为VCC网络,之前的只是取个VCC的名称而已,与VCC网络相同的元件管脚及过孔,均会与该层自动连接,从而不用布线。
用同样的方法给GND层定义网络,将其定义为GND网络。
点击OK关闭对话框。
这时,我们发现,在PCB中,有些元件的PAD的中心有一个十字,这是因为,这个焊盘的网络是VCC或者GND,说明已经与相对应的网络连通。
如图:

在图中,焊盘上的十字架的颜色就代表相对应连接内电层的颜色。
如:
内电层GND为棕色,则焊盘的十字也为棕色。
7、看内电层
在PCB内层设置完毕后,我们要来查看内层是否正确,当然,最先是用眼睛来查看整个板了。
下面,我们来看看下面这个图
