Realistic Simulation for High Tech
Manufacturers and suppliers use Realistic Simulation Solutions from SIMULIA to evaluate design alternatives, collaborate on projects and leverage computing resources for more efficient design analysis.
Circuit Boards
Circuit board designers must place components to optimize both thermal and mechanical performance. The design of flexible circuit boards poses additional challenges—the determination of the flat board shape and layer structure for optimal performance in the flexed configuration and then the fatigue performance as the circuit board flexes.
The Abaqus Unified FEA product suite from SIMULIA allows manufacturers of rigid and flexible circuit boards to make important decisions about component placement and support design. The SIMULIA solution includes state-of-the-art simulation techniques for modeling circuit boards undergoing mechanical (bending, shock/drop, flexing) and thermal loading. For flexible circuit boards, fatigue can be considered to allow lifecycle predictions. Modern circuit boards are complex, multi-layered structures and our solution also includes industry leading progressive fracture/failure capabilities to allow delamination modeling.
