This paper reviews sub 1.00mm ball pitch solder joint reliability (SJR) challenges under compressive loaded thermal cycling stressing. It focuses on different types of heat sinks and their compressive load effect on solder joint thermal fatigue performance. Heat sink configuration and compressive load applied was found to be important factors in determining failure region across ball grid array (BGA). Lastly, board thickness effect under different heat sink configuration was also evaluated
