焊點可靠性，POP組裝與空洞控制培訓(xùn)班(李寧成)課程介紹：

您能從此課程中學(xué)到哪些內(nèi)容：
本課程涵蓋了電子封裝和組裝應(yīng)用中軟釬焊焊點的可靠性表現(xiàn)。討論了焊點的機(jī)械失效模式機(jī)制和提高可靠性的方法。在電可靠性方面，詳細(xì)討論了由于微型化的快速發(fā)展而導(dǎo)致的嚴(yán)重的焊點，銅柱以及再分布線的電遷移問題。在組件類型方面，詳盡地回顧了POP以及其他的底部終止組件封裝方式，包括材料選擇，工藝，可靠性，和提高可靠性的方法。介紹了環(huán)氧助焊劑這種最具潛力的解決方法，并將其與其他解決方案進(jìn)行比較。最后，以QFN熱板設(shè)計為實例，講授了回流焊中，特別是在PoP和其他更容易產(chǎn)生氣孔的封裝方式中氣孔控制方法。這些控制方法包括在材料，工藝和設(shè)計方面的考慮。
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.

誰應(yīng)該參加此課程：
凡對電子封裝和組裝應(yīng)用中實現(xiàn)焊點高可靠性（特別是對PoP封裝）感興趣的，并想了解如何實現(xiàn)的焊點高可靠性的人員均可參加本課程
Who Should Take This Course:
Any one who care about achieving high reliability solder joints for packaging and assembly applications, particularly that of PoP, and like to know how to achieve it should take this course.
