Dynamic dispensing for Underfill Encapsulation set up

Note: The option to Perform dynamic analysis is available only for 3D models.

Make sure you have assigned nodes along your dispensing path as injection locations, and you know which one will be the start of the dispensing path and which one will be the end. It is recommended that all nodes on the injection plane along the dispensing path have been assigned as injection locations.

Note: A minimum of 4 injection locations are required on each injection plane.

To set up dynamic dispensing, first you will define the properties associated with the start and end nodes, and then you will assign the start and end nodes.

1. Click (Boundary Conditions tab > Dispensing panel > Set Controller) to open the Set Dispensing controller dialog.
2. Click Edit to open the Dispensing controller dialog.
3. In the Dispensing controller dialog, in the Start node or end node of the pass section, select Start node from the drop-down menu, and type a unique name for the start node properties in the Name box.
4. Click Edit data to open the Dispensing data dialog.
5. Decide how many dispensing passes you would like to perform and the volume of encapsulant you would like to dispense in each pass, and enter the information in the relevant boxes. Make sure that the start time of the first pass is 0, and that the start time of all subsequent passes is after the end time of the previous pass. Click OK to close the Dispensing data dialog, then click OK again to close the Dispensing controller dialog.
6. In the Set Dispensing controller dialog, if you haven't already created an end node property, click New to create one.
7. In the Start node or end node of the pass section, select End node from the drop-down menu, type a unique Name for the end node properties, and click OK. The start node properties, end node properties, and number of passes have now been defined.

   Now you need to assign these properties to your chosen start and end nodes:

8. In the Set Dispensing controller dialog, select the start node properties you defined, then click on your model to select the start node of your dispensing path (this node must already have been defined as an injection location). A cross will appear on the selected node. The orientation of the cross is irrelevant, but confirm that the center of the cross is superimposed on your selected start node.
9. In the Set Dispensing controller dialog, select the end node properties you defined, then click on your model to select the end node of your dispensing path (this node must already have been defined as an injection location). A cross will appear on that node. The orientation of the cross is irrelevant, but confirm that the center of the cross is superimposed on your selected end node.
10. Close the Set Dispensing controller dialog.
11. Click (Home tab > Molding Process Setup panel > Process Settings) and activate dynamic dispensing by clicking on the Perform dynamic analysis checkbox, then click OK.
12. Once you have set all your other processing conditions, click Analyze in Cloud in the Study Tasks pane, to start the simulation.
