| Abstract: | Flip-chip onto organic substrate becomes a mature process with a stable structure.Underfill technology effectively enhances the flip-chip cycle fatigue life and reliability of packaging process.The issues of lack of reworkability limiting the final yield of this technology and leading to the increase of cost are analyzed.It is pointed out that reworkable underfill is the key method for addressing nonreworkability of the underfill,so it is very important for electronic packaging.Reworkable underfill technolo... |
