Verification of Drop Impact Simulations Using High-Speed Camera Measurements

Abstract

The increased use of mobile appliances in today's society has resulted in an increase of reliability issues related to drop performance. A common method to assess the drop performance is the JEDEC specified drop impact test [1]. In this research the solder loading is investigated by means of drop impact simulations and high-speed camera measurements. The measurements are used to enhance the simulations by tuning the damping parameters. This results in models that are replicating the drop impact amplitudes and are thereby capable of determining the critical solder joint.
