Abstract
The paper simulates the pressure of extreme marine environment, carries out pressure test on BGA devices, studies the changes and trends of BGA solder joints before and after test, analyses the reliability changes and the potential risks. The model of BGA solder joints is established by means of finite element modeling, and the influence of the position and size of voids in BGA solder joints after reflow soldering in pressure test is studied. Therefore, the preventive inspection measures for the corresponding reliability risk of BGA solder joints are put forward, which provides reliability assurance advice for BGA solder joints exposed to extreme marine environment.
