Abstract:

To investigate the long term reliability of plastic ball grid array packages in aerospace application, a design of experiments was conducted to address assembly process, primed circuit board pad type, underfill, and multiple environmental loadings. This paper discusses the design of experiments and the test results, including the failure analysis. Virtual qualification was also performed to simulate the solder joint reliability under thermal cycling and vibration loadings.
