There are compulsory modeling and meshing prerequisites for running a Microchip Encapsulation analysis.
In addition, consult the following:
Modeling the wire for microchip encapsulation analysis
Modeling for wire sweep detail analysis (3D)
Modeling the paddle for Microchip Encapsulation analysis
Modeling for cross-flow analysis for microchip encapsulation
The illustration below shows an example of a model which has been prepared for Microchip Encapsulation analysis. The illustration shows the pot (a), runner, wire (b), chip cavity (c), and leadframe (d). On the left is a top view. On the right is an angled view.
