Adding and Removing Layers

Layers can be added three ways: though the Layer menu, by right-clicking in the Stackup page, and in the Layer pane. With each method, select whether to insert the new layer above or below a layer selected in the Grid Control pane. Right-click Grid Control to access quick options to insert a new signal or dielectric layer.

Via layers are only available in overlapping stackups and are added in a unique process.

Adding a Layer

1. From the Grid Control pane of the Edit Layers window, click a layer that are above or below the new layer.
2. Do one of the following:
   • From the Grid Control pane, right-click selected layer and click an Insert command.
     Note:

     If you click an Insert signal or Insert dielectric command, the layer is added with no further steps.

   • Open the Layer menu and click an Insert command.
   • From the Layer pane, click Insert to open the Add Stackup Layer window.

     

3. Enter a name for the new layer in the Name field.

4. Select a type of layer on the Type drop-down menu. Different types are available for physical (stackup) layers and non-physical (non-stackup) layers.

   Type	Physical Layer	Purpose
   signal	Y	For drawing traces.
   dielectric	Y	Acts as a substrate upon which signal layers border. Infinite in the XY plane.
   assembly	N	For assembly geometry and text. Only one assembly type layer can be defined.
   silkscreen	N	For silkscreen geometry and text. Only one silkscreen type layer can be defined.
   soldermask	N	For soldermask geometry. Only one soldermask type layer can be defined.
   solderpaste	N	For solderpaste geometry. Only one solderpaste type layer can be defined.
   glue	N	For glue geometry. Only one glue type layer can be defined.
   user	N	For user-defined geometry and text. Any number of user type layers can be defined.
   post-processing	N	Provides placement for a 3D Line primitive that can then be used for post-processing calculations.

5. Click OK. The layer is added above or below the selected layer, depending on what was picked.

Removing a Layer

1. From the Edit Layers window, click the layer(s) you want to remove on the stackup.
2. Do one of the following:
   • From the Grid Control pane, right-click unwanted layer and click Remove.
   • Open the Layer menu and click Remove command.
   • From the Layer pane, click Remove.
3. Confirm the action. The layers you selected are removed on the stackup.
