Pads copper-clad design settings

 

Section 13th-copper-clad (copper pouring)
Many Printed Board (printed circuit board) design systems support various types of copper-coated (copper)
Pouring) or area filling mode, but it rarely reaches the pads layout copper (copper pour) such
This feature is powerful and flexible. Once you have learned some basic strategies, you can quickly
Quickly create and edit the area of the insulated copper area, power supply, and ground layer used to shield (shielding.
This section of this tutorial introduces the following:
· Create a copper pour outer border (outline)
· Flooding copper-clad border (pour outline)
· Edit the copper pour filling (hatch)
· Some advanced copper-coated Functions
· Copper operation
Create a copper pour border (outline)
Pour outline defines the ry of the copper pour.
When you use the perfusion (flood) command to establish the injected copper area, the copper-coated border (pour outline) now
It is not visible for the moment. After pads layout is filled with copper hatching, copper-coated
Border (pour outline ). The copper-clad border (pour outline) still exists. If you enter the Po, press back
Enter, you can still see them. This command can switch the display back and forth, that is, display the copper-clad edge
Switch between pour outline and poured copper hatch.

Edit copper pour hatch)
The hatch areas is an area created based on the hatch outline.
The method is the same as the method used to edit the copper border (pour outline ),
Select them and then select commands from the pop-up menu to execute them. When you change the fill
After the border (hatch outline), you must regenerate the specific internal filling content.
You can use the following two methods to regenerate the internal filling content:
· Select the fill icon from the drafting tool box, and re-select the selected area
Generate.
· Select Tools/pour manager and select the hatch table.

1. Select to fill all (hatch all) or quickly fill (fast hatch) to regenerate the fill

Save design backup
Save the design with a new file name.
1. Select File/Save As. The File Save As dialog box appears.
2. Enter previewpour. PCB in the file name box.
3. Select save ).
Pads layout saves changes and makes previewpour. PCB the current file.
Note: You can perform the following operations to introduce the advanced functions and copper pasting functions of the copper filling part.
Exercise, but do not follow the steps and save part of this tutorial.
Assign a network by clicking the mouse
After a copper pour shape outline is drawn, select the shape of the entire outline,
Right-click query/modify in the pop-up menu to bring up the query/modify drafting dialog box.
To assign a network, click the assign net by click button in the lower-right corner of the window, and then
Zoom out this dialog box and go to the PCB diagram to find the desired network location. Click the left mouse button.
You can select a network without looking for it in the Network List. When you press this button, you can view
The following prompt appears in the lower left corner of the pads layout work interface: Assign net to copper: click at
Pin, via, copper, link or trace of net to assign .. Prompt that you can click the corresponding network manager
Designate a network, such as foot, pass hole, copper skin, or strip.

Flood over via settings
If you need to overwrite all the holes (flood over) during copper filling, click the drafting properties field.
The options button in the upper-right corner will pop up the following dialog box.

Select the option flood over vias. their respective effects are as follows: the left side is normal.
The Effect of Copper filling on the hot pad is shown in the figure on the right. Note: This setting
Only for the set copper pour, and it only affects via. If this effect is required for pad,
Additional settings are required.

Define the priority of the copper pour
When multiple copper pour overlaps, we can set the priority levels of each copper pour.
For copper filling. The following two parts overlap with each other in the copper pour. We can set their own
First Grade Copper filling. We use different colors to distinguish two networks.

1. Right-click the menu and select shapes. Click a yellow shape on the left.
Right-click query/modify, and click the Options button in the upper-right corner &
In the hatch preferences dialog box, enter 1 at the flood priority in the lower-right corner. Click OK
Button, on the pop-up proceed with flood? Dialog box, select No.

2. perform the same operation on the green copper pour on the right and set its priority value to 2.
3. Start copper filling now. Select Tools/pour manager... /Flood, select flood all, and
Click Start. The result of copper filling is as follows. The yellow copper pour takes precedence over the green one.

4. input the Po using the modeless command. We can see that the outline format is displayed.
We edit the yellow priority again, which is similar to the previous operation and sets its priority to 3.
5. We will perform the copper filling operation again. The effect of copper filling is as follows. green copper pour takes precedence over yellow.

From the above operations, we can see that the lower the number, the higher the priority.

Tip: priority numbers can be set from 0 to 250.
Copper Function
The difference between copper and copper pour is that after drawing the shape Frame of the copper,
All of the inside is covered with copper instead of any network and components. The shape of the copper pour
After the frame is completed, flood will be implemented, which will avoid the welding pad and overholes of different networks at full distance.
For the target of the same network, use the flower hole or flood over for connection.
Next we will look at the copper paste operation process.
In the case of a PCB diagram opened above,
