… The recent trend in circuit assemblies is to bond larger IC packages to PCB (Printed-circuit Board) by BGA (Ball Grid Array) solder joint and underfills. … This would induce more intricate CTE (Coefficient of Thermal Expansion) mismatches among the PCB, the IC package, the solder joint and the underfill. … The underfill, which fills the gap between solder balls, is usually used to increase mechanical strength, and to improve the reliability of the solder joint. …
