Bga Shock Vibration at Amelia Truebridge blog

Bga Shock Vibration. It is found that at elevated temperature, vibration and shock can cause the accumulation of inelastic strains and damage in solder joints. However, due to environmental loads such as vibration and impact during its production and application, defects inevitably emerge in bga. This investigation qualifies the random vibration response of five essential solder compositions in ball grid array (bga) solder joints. A variable mass shock test and an incremental shock test procedure were developed to evaluate bga solder joint shock failures. Studied the failure modes of snpb bga solder joints under random vibrations, temperature cycling, and combined conditions of. During random vibration, bga solder ball would endure not only mechanical shock, but also peeling and compressive stress. Test vehicles with daisy chain plastic and ceramic bgas (cbgas) ranging from 256 to 625 i/o count were subjected to random vibration/shock. Multiple shock damage failure of ball grid array (bga) solder joints is one of the important reasons for reusable spacecraft mission failure.
