About dynamic dispensing

Dynamic dispensing for underfill encapsulation enables you to simulate the filling pattern from dispensing path(s) more realistically.

Dynamic dispensing is supported for the following mesh types:

Multiple dispensing paths

You can set up multiple dispensing paths, but each path must have a start controller and an end controller. When setting up multiple dispensing paths, ensure that you leave at least 1 layer of nodes free from injection cones, between one dispensing path and the next.

Different dispensing volumes per pass

Decide how many dispensing passes you want. For each dispensing pass, the dispensing speed is constant. However, different passes can have different speeds. Specify different dispensing volumes for different passes in the Dispensing data dialog.

The sum of the dispensing volumes, over all passes, should total at least 100% of the cavity volume to avoid short shot. The total dispensing volume can be greater than 100% of the cavity volume.
