PROTEL DXP 中的内层分割是怎样的？

A3:在PROTEL DXP 中，电源层可以被分为许多独立的单元，此分割过程就是根据你所对分离距离设定的行的宽度，把内层切成许多部

分。如下是此过程的简要概述：

1． 把电源层变成ACTIVE LAYER，注意电源层在边界周围自动显示了一系列PULLBACK 线，显示当前的板子的形状。如果这个形状不正确

，你必须重新定义板框，请参考问题2。在LAYER STACK MANAGER 中定义PULLBACK 区域，编辑每一个电源层建立PULLBACK 区域。

2． 要把电源层分割为2个区域，从命令栏中选择Place>Line,然后开始调整边界外面的PULLBACK 线，在板上放线片段定义分开的路径，

当PULLBACK 线拉回外面结束。 当你右击鼠标退出电源层画线模式，被检查后，两个独立的区块被建立了，想要改变分隔宽度，只要在放

置线时，按住TAB键，就可修改。

3． 对每一个分离的区域进行分配网络。你也可以在NAVIGATOR中回顾和修改分离的区域。

注意：内层可以被分为任意多的区域，可以在PUULBACK线边和一个现有的分割线上开始和结束。

在内层上选择"Blow out"（创建自由区域的铜面），放置线段建立无铜区域。

In Protel DXP power planes can be split into any number of separate regions. You can think of the splitting

process like cutting or slicing the plane into sections, where the width of the line you place defines the

separation distance.

Following is a summary of the process:

1. Make the plane layer the active layer. Note that the plane layer automatically presents with a set of pullback

tracks around the boundary, tracing the current board shape. If this shape is not correct you must redefine the

board shape, refer to Item 3426 for details on defining the board shape. The pullback distance is defined in the

Layer Stack Manager, edit each plane layer to set the pullback distance.

2. To split the power plane into 2 regions, select Place " Line from the menus, then starting just outside the

boundary pullback tracks, place line segments across the board to define the separation path, finishing just

outside the boundary pullback tracks again. When you right-click to drop out of place line mode the plane is

analyzed, and the 2 independent split regions are created. To change the separation width during line placement

press the Tab key.

3. Double click on each split region to assign the net. You can also review and edit split planes in the

Navigator panel.

Notes:- The plane can be split into any number of regions, always start and end on a boundary pullback track or

an existing split line.

- To 'blow out' sections of a plane (create copper free regions), place line segments to build up the no-copper

region.
