PCB Layout CAD : PCB Settings

Layers

Configure layer settings for PCB documents. In the Layer setting dialog, it is possible to configure "Physical Layer", "Layer Settings" and Display Layer Settings.

Item Description

Physical Layer

Configures electrical layers such as Top and Bottom layers.
It is possible to set the number of board layers such as a 2-layer board or 4-layer board, and the materials.

Layer Settings

Customize layers such as layers for Dimensions and layers for comments can be added to Physical Layers.
It is also possible to set display/lock, object color, and the fill style for each layer.

Display Layer Settings

Toggling can be done easily by registering display of the PCB drawing that is being designed.

 

For more details about opening the PCB Settings screen, refer to About PCB Settings.


Layer Screen

Explanation of Layers
Layers Description

Top, Bottom

Indicates the Top layer(Component side) and Bottom layer(Solder side). (These cannot be deleted because they are predetermined layers.)

noname

Indicates an added inner signal layer. Its layer name can be changed.

Other

Common layers such as Board (Board Outline) for all layers.

System

Layer used for the system such as Drills and Rats. (These cannot be added or deleted because they are predetermined layers.)

 


Physical Layer

Configure Physical Layer settings.
For a 2-layer board, configure settings for the "Top" and "Bottom" layers.
For a 4-layer board, configure settings for the "Top", "Layer2", "Layer3", and "Bottom" layers.

Thickness and materials, etc., are used for Recommended Width (Impedance Control).
When not necessary, etc., it is OK not to configure these settings.

Adding Physical Layers
The following will explain how to add physical layers.
(1) Click "Add".
An inner layer will be added.
You can also add inner layers by entering the number of layers from the "Layers" button.
Inner layers will be added according to the specified number of layers.

 

Deleting Physical Layers
The following will explain how to delete physical layers.
(1) Select an inner layer and then click "Delete".

*When deleting a layer, execute by selecting the lowest layer of the inner layers (noname〇).
If another layer is specified, it will not be possible to select "Delete".
The selected inner layer will be deleted.
You can also delete inner layers by entering the number of layers from the "Layers" button.
Inner layers will be deleted according to the specified number of layers.

It is also possible to add/delete layers while designing. However, when deleting an added layer,
it is necessary to delete all objects placed on that layer.


Layer Settings

It is possible to configure customize layers included in each layer and color settings.

For surface layers (Top/Bottom), "Silk", "Electric", "Paste", "Solder", "Assembly", "KeepOut", "DesignRule", and "Dimension" layers are automatically prepared.
When a Physical Layer is added to an inner layer, an "Electric", "KeepOut", and "DesignRule" layer are created automatically.
For Other layers, "Board", "KeepOut", "DesignRule", and "Dimension" layers are prepared.
For System layers, "Drill", "Rat", "ConnectionPoint", "DRC/MRC Error", "DRC/MRC Error(Approved)", "Background Color", "Cursor", "Selected Item", "GRID", "GUIDE", and "Origin Point" are prepared.
In addition to the above, it is possible to add customize layers (Dimension, Comment, Assembly Drawing) freely.


Explanation of Default Layers

The following will explain the default layers that are prepared automatically.
Default layers cannot be deleted.

Layers Description

Silk

This is the Silk object layer, and it includes Non-Electric Objects such as References, Lines, and Text.

Electric

This is the Copper layer, and electric objects such as Routes, Planes, Pad Lands, and Via Lands are automatically included in this "Electric" layer.

Route

This is the Route object layer in the Electric layer.

Plane

This is the Plane object layer in the Electric layer.

PadStack

This is the Pad Land object layer in the Electric layer.

ViaStack

This is the Via Land object layer in the Electric layer.

Paste

This is the metal mask and paste mask layer. When metal mask settings are configured for the CHIP pad,
objects will be created in this layer automatically. It is also possible to place objects such as Lines arbitrarily.

Solder

This is the solder resist and solder mask layer. When Solder Resist Settings are configured for a Pad/Via,
objects will be created in this layer automatically. It is also possible to place objects such as Lines arbitrarily.

Assembly

This is the official outline line layer for components. For IPC Footprints, official outline lines for components are created in this layer automatically. It is also possible to prepare this when creating a footprint.

KeepOut

This is the Keep Out Area layer.
When this setting is configured for individual layers, it is created in the KeepOut layer of each layer.
When common for all layers, it is created in the KeepOut layer for Other.

DesignRule

This is the Design Rule Area layer.
When this setting is configured for individual layers, it is created in the DesignRule layer of each layer.
When common for all layers, it is created in the DesignRule layer for Other.

Dimension

This is the Dimension layer.
For "Create Component Dimension Automatically", by default, dimensions are automatically created in the Dimension layer.
For "Create Board Outline Dimension Automatically", by default, dimensions are automatically created in the Dimension layer for Other.

Board

This is the Board Outline layer. A closed drawing is drawn using Lines and Arcs, etc.

 


System Layer
Layers Description

Drill

The color of the Drill on the board can be set. Drills created using Pads and Vias are recognized automatically.

Rat

The color settings for Lines (Rats Net) that express Net connections can be configured.

ConnectionPoint

The color settings for Connection Point objects can be configured.

DRC/MRC Error

The color of DRC/MRC error marks can be configured. The color of error marks for "Not yet" errors is set by this setting.
