Documentation is a key part of the design process, and is particularly important for designs with a complex layer stack structure, such as a rigid-flex design. To support this, Altium Designer includes a Layer Stack Table, which is placed and positioned alongside the board design in the workspace.

Include a Layer Stack Table in the design documentation, note the small board map under the table that shows where the different layer stacks are used.

The Layer Stack Table was introduced in Altium Designer 14. The Layer Stack Table is an intelligent design object, meaning it can be placed and updated as the design progresses. Prior to this, the layer stack was documented by placing a Layer Stackup Legend from the Tools menu.

Placing a Layer Stack Table

To fully document the layer stack, place a Layer Stack Table (Place » Layer Stack Table). The Layer Stack Table details the: layers; material; thickness; and dielectric constant. It also includes a key and an option map, which shows the layer stack used in each region of the board.

When the command is launched:

  1. A Layer Stack Table will appear floating on the cursor, ready to be placed into the workspace onto the active layer.
  2. Click to place the Layer Stack Table.
  3. Note the Board Map that appears below the table, this is an outline of the board showing how the various layer stacks are assigned to regions of the board. It can be scaled, or hidden if required.
  4. Double click anywhere on the Table to open the Layer Stack Table dialog, as shown below. Edit the settings as required.

Configure the Layer Stack Table settings in the dialog.
