• This slide shows an instance of the FEA-based warpage analysis.

• We can see how idealizations supported by the APM are used and displayed in the lower left region of the screen.

• The user enters the temperatures of interest (e.g., for the lamination temperatures as here) and clicks the <Calculate> button to see the deformations on a local PWB section.

• The program automatically extracts idealized attributes from the APM and creates a finite element job file and submits it to the FEA tool (Ansys in this case) for automated execution.

• The user receives results back in PWB-specific terms that are then checked against allowable values.
