Parametric Study of Thermal Characteristics of Plastic Ball Grid Array by Computational Fluid Dynamics
White Paper
ABSTRACT
This presentation provides a design guide for cavity-up over molded plastic ball grid array packages. It utilizes Mentor’s FloTHERM CFD simulator for parametric benchmarking in both forced and natural convection environments.
Factors investigated include material selection, component sizing, circuitry and thermal ball arrangement. Detailed modeling was necessary for accurate thermal characterization of each unique device.
