計(jì)方面的考慮。
What You Can Learn From This Course:
This course covers the solder joint reliability performance for packaging and assembly applications. The mechanism of joint mechanical failure modes and approaches for improving reliability will be discussed. As to the electrical reliabilities, electromigration will be discussed in great details on solder, Cu pillar, and redistribution line due to the rapid advancement of miniaturization and the resultant serious electromigration problems. Regarding the component type, Package on package (PoP) as well as other bottom-terminated components will be reviewed thoroughly, including materials selection, processes, reliabilities, and approaches of enhancing the reliability. Being the solution with the highest potential, epoxy flux will be introduced and will be compared with other solutions. Finally, voiding control at reflow soldering, particularly at PoP and other packages more prone to have voids, will be instructed. The control includes considerations from materials, processes, and designs, with QFN thermal pad design serving as a demonstration on control.
