• Units - use to select the default measurement units for the current PCB document. Default units are used to display any distance-related information on the screen or in reports. The default units are always used if a unit's suffix (mm or mil) is not entered when specifying any distance related information. 
• Designator Display - use this field to determine how designators are to be displayed. It can be difficult to position the designator strings in a multi-channel design, as they can end up being quite long. As well as choosing a naming option that results in a short name, another option is to display just the original, logical component designation instead. For example, C30_CIN1 would display as C30. This would of course necessitate some other notation being added to the board to indicate the separate channels, such as a box being drawn around each channel on the component overlay. The following options are available:
  • Physical - choose to display the physical designators. These are the designators displayed on the compiled tab views of the schematic source documents. For multi-channel designs, the designator format is determined by the Designator Format field on the Multi-Channel tab of the Project Options dialog. Physical designators are unique, e.g., R1_CH1.
  • Logical - choose to display the logical designators. These are the designators displayed on the Editor tab views of the schematic source documents. Logical designators are not unique; for example, the R1_CH1 physical designator will become simply R1.
• Sheet Settings - use this region to configure the PCB sheet.
  • X/Y - enter the X and Y coordinates for the bottom left corner of the sheet. This distance is measured from the absolute origin, which is the bottom left corner of the design space.

To specify the units when entering a size, add the mm or mil suffix to the value.
  • Width - enter a width for the sheet here. The sheet provides an area that emulates the traditional drawing sheet and is useful for placing information such as dimensions, notes and title blocks. Information placed on mechanical layers can be linked to the sheet so that they only display when the sheet is being displayed. Sheet size can be defined in either metric or imperial units regardless of the default units (which are determined by the Units setting). To specify the units when entering a size, add the mm or mil suffix to the value.
  • Height - enter a height for the sheet here. The sheet provides an area that emulates the traditional drawing sheet and is useful for placing information such as dimensions, notes and title blocks. Information placed on mechanical layers can be linked to the sheet so that they only display when the sheet is being displayed. Sheet size can be defined in either metric or imperial units regardless of the default units (which are determined by the Units setting). To specify the units when entering a size, add the mm or mil suffix to the value.

The Stackup tab allows you to edit the layer properties of the Layer Stack.

The Layer Stack Manager mode of the Inspector panel: an Overlay layer (left image), a signal layer (middle image), and a dielectric layer (right image).

• Layer
  • Name - the name of the layer.
  • Manufacturer - the layer manufacturer.
  • Material - the layer material.
  • Thickness - the thickness of the signal layer.
  • Dk - this is the Dielectric Constant (also referred to as εr in electromagnetics). This indicates the relative permittivity of an insulator material, which refers to its ability to store electrical energy in an electric field. For insulating purposes, a material with a lower dielectric constant is better and in RF applications, a higher dielectric constant may be desirable. In addition, the lower the relative dielectric constant, the closer the performance of the material to that of air. This property is critical to matching the impedance requirements of certain transmission lines.
  • Df - this is the Dissipation Factor. This indicates the efficiency of insulating material by showing the rate of energy loss for a certain mode of oscillation, such as mechanical, electrical, or electromechanical oscillation. In other words, this is the property of a material that describes how much of the energy transmitted is absorbed by the material. The greater the loss tangent, the larger the energy absorption into the material. This property directly impacts the signal attenuation at high speeds.
  • Process - displays the copper plating process that is applied to the base copper that makes up the outer signal layers of the PCB (the Top Layer and Bottom Layer). 
  • Weight - the weight of the copper per unit area, usually expressed in ounces/square foot (e.g., 0.5 oz/ft²).
  • Orientation - this defines which way the components point (orient) on that layer. For the top and bottom sides, this is set automatically for a new board. Choices include: Not allowed, Top, and Bottom.

  • Copper Orientation - this defines the direction that the copper is laminated onto the core. Use the drop-down to select Above or Below, which determines the direction from which it is etched.

    The Copper Orientation can also be chosen using the drop-down in the Copper Orientation column of the Layer Stack. To enable the column, right-click in the header, choose Select columns then enable the Copper Orientation entry in the Select columns dialog.
  • Frequency - this is the frequency at which the material is tested and the value that Dk / Df corresponds to a certain frequency. Frequency is also taken from material references.
  • Description - enter a meaningful description.
  • Constructions - for dielectric layers, this displays the constructions of the layer. The numerical reference relates to the structure of the woven glass fabric used in the dielectric layer material; these are standard references used by PCB fabricators.

  • Resin - displays the resin percentage of the layer.

    Notes on Constructions and Resin:

    The choice of laminate construction can significantly impact both cost and performance. As should be expected, a single-ply construction will typically represent cost savings compared to a multiple-ply construction. The magnitude of these savings will depend on the specific glass styles involved and a host of other parameters. Performance can also be affected and should be considered when specifying the constructions to be used. First, single-ply constructions are often lower in resin content.  The other main benefit of single-ply constructions is dielectric thickness control, beyond resin content considerations. Tighter thickness tolerances can be achieved using a single-ply construction.

    Constructions with relatively lower resin contents are often preferred since they result in less z-axis expansion and can, therefore, improve reliability in many applications. In addition, lower resin contents can also improve dimensional stability, resistance to warpage, and dielectric thickness control. On the other hand, constructions with higher resin contents result in lower dielectric constant values, which are sometimes preferred for electrical performance. In addition, a certain minimum resin content is required to ensure adequate resin-to-glass wet-out and to prevent voids from occurring within the laminate. The ability to wet out the glass filaments fully with resin is also important for CAP resistance.

  • GlassTransTemp - this is the Glass Transition Temperature (also known as T_G) and is the temperature at which the resin changes from a glass-like state to an amorphous state changing its mechanical behavior, i.e. expansion rate.
  • Note - enter any pertinent notes for the layer.
  • Comment - enter any necessary comments for the layer.
• Board
  • Layers - the number of conductive layers.
  • Dielectrics - the number of dielectrics.
  • Conductive Thickness - this is the sum of the thicknesses of all signal and plane layers (all copper or conductive layers).
  • Dielectric Thickness - the thickness of dielectric layer(s).
  • Total Thickness - the total thickness of the finished board.

The Via Types tab is used to define the allowed Z-plane layer-spanning requirements of the via(s) used in the design.

• Via Type
  • Name - the name of the via. The software automatically detects the type based on the layers that have been chosen and names the via accordingly.
  • First layer - the first layer the via spans.
  • Last layer - the last layer the via spans.
  • Mirror - when enabled, a mirror of the current via that spans the symmetrical layers in the layer stack is created.
