ADHow to set the safe spacing and copper cutting of copper plating area in PCB? [Copy link]

After the PCB design is completed, in order to enhance the anti-interference performance, we often perform some copper operations, and sometimes require the safe spacing of the copper area to be different from the safe spacing of the PCB wiring.

We can achieve this in the following two ways:

1. Through the copper manager to achieve

We use the shortcut keys on the menu to perform copper operations. You can choose solid copper or grid copper mode, and then select Connect to Net under Net options to connect to the appropriate network, generally connected to the GND network, and generally select the Remove Dead Copper menu below. Then perform copper operations in the appropriate area.

After laying the copper, you can use Tools—Polygon Pours—Polygon Manager to perform some corresponding copper laying operations.

That's it.

Because the safety spacing has been modified,The system will automatically prompt to update the copper, click YES.

Second, set the safe spacing of the copper plating area through rules

In the PCB interface, use the D+R shortcut keys, right-click Design Rules—Electrical—Clearance on the left in the pop-up menu, add a new rule, then click on the Advanced menu on the right, then select Object Kinds is in the drop-down box in the pop-up menu, select Poly on the right, and then click OK.

In the pop-up menu, there is a word "Ispolygon". Please change this word to "Inpolygon", then write the number you need under the safety spacing below, and click OK.

Sometimes we need to delete some broken copper after laying the copper. Now we can do it very conveniently. Click Place—Polygon Pour Cutout.

Then select the copper you want to delete.

The system will prompt you to re-lay the copper, click YES.

After re-laying the copper, you can see that a piece of copper has been dug out, as shown in the following figure.

然后选择好你要删除的铺铜。

系统会提示你进行重新铺铜,点击 YES 。

重新铺铜后可以看到有一块铜皮被挖掉了,如下图所示.
