Test Rig

Define the geometry, placement, and physics of the JEDEC test rig using Generic and PCB QuickParts.

To define the table:
  1. Right-click the QuickParts node and select New QuickPart > Generic > Block.
  2. In the Edit dialog, set Name to Table.
  3. Set the following Geometry properties:
    Property Setting
    X 305.0 mm
    Y 305.0 mm
    Z 12.5 mm
  4. To preview the block geometry in the Graphics window, click Update at the bottom of the dialog. Change the view to obtain a similar table position to the one shown below.
    For information on how to change the view in the Graphics window, see Mouse Configurations and Changing the View.


  5. Click OK.
To define the PCB test board:
  1. In the Graphics window, right-click the top surface of the table and select New QuickPart > PCB > Rectangular.
  2. In the Edit dialog, set the following Geometry properties:
    Property Setting
    X 114.5 mm
    Y 101.5 mm
  3. To define a centered Placement of the PCB above the table, set the Location vector to [0.0, 0.0, 145.0] mm.
  4. Click Update.


To account for the effect of conductive tracks and non-conductive substrate on the heat transfer within the PCB, set the following Physics properties:
  1. Set the Thermal Specification to Specify By Layer.
  2. Set the metal fractions of the layers to the following values:
    Name Metal Fraction
    Layer 1 0.9
    Layer 2 0.01
    Layer 3 0.9
  3. Click OK.
To define the PCB-edge:
  1. In the Graphics window, right-click the PCB face that is highlighted below (note the coordinate system) and select New QuickPart > Generic > Block.


  2. In the Edit dialog, set Name to PCB-edge.
  3. To set the height of the block based on the thickness of the PCB, right-click one of the short edges of the PCB as highlighted below and select Set Dimension... > X.


  4. Set the following Geometry properties:
    Property Setting
    Y 80.0 mm
    Z 5.0 mm
  5. Set the Location vector to [0.0, 0.0, 0.0] mm.
  6. Click Update.


  7. Within the Physics section, click the Solid material box and select Al.
  8. Click OK.
To define the connector:
  1. On the PCB, right-click the face that is highlighted below and select New QuickPart > Generic > Block.


  2. In the Edit dialog, set Name to Connector.
  3. Set the following Geometry properties:
    Property Setting
    X 5.0 mm
    Y 110.0 mm
    Z 10.0 mm
  4. Set the Location vector to [0.0, 0.0, 0.0] mm.
  5. Click Update.


  6. Click OK.
Subtract the PCB-edge from the Connector:
  1. Right-click the QuickParts > Connector node and select Edit Interactions.
  2. In the Subtract group box, click the Solid Quick Objects box and select PCB-edge.
  3. Click Apply and Close.
To define the stand:
  1. On the connector, right-click the face that is highlighted below and select New QuickPart > Generic > Block.


  2. In the Edit dialog, set Name to Stand.
  3. Set the following Geometry properties:
    Property Setting
    X 171.0 mm
    Y 200.0 mm
    Z 12.5 mm
  4. Click Update.
  5. Using <Ctrl>, multi-select the top surface of the table and the bottom surface of the stand. Right-click and select Position... > Snap.


  6. Multi-select the two faces that are highlighted below, right-click and select Position... > Set Distance.


  7. In the Set Distance dialog, set Distance to 13.0 mm and click OK.
  8. Click OK.
    The setup of the test rig is now complete.


  9. Save the simulation .
