Our warpage solver primarily considers two main effects: differential temperature and differential shrinkage effects.

Differential shrinkage effects The differential shrinkage displacement represents the in-plane shrinkage due to PVT distribution. The displacement is calculated based on the average volumetric shrinkage across the thickness of the same cutting plane. Since this effect averages across the thickness, it does not vary in the vertical (thickness) direction.

On the other hand, Differential temperature effect displacement is calculated with the difference of volumetric shrinkage through thickness. it represents the out-of-plane warpage.

 

• • Users can select the option to output the results for both the differential shrinkage and differential temperature effects.
