Inverse Design for Low Warpage Ultra-Thin Packages Using Constrained Particle Swarm Optimization
IEEE Access, 2021 Warpage of electronic packages is the result of mismatch in the coefficient of thermal expansion (CTE) between the silicon die (CTE = 2.6ppm/°C) and the substrate (CTE = 15–25 ppm/°C).
