| Summary: | This paper will be discussed some aspects of surface morphology and elemental analysis on the solderability problem which caused non-wetting on top of die metallization layer. In this study few good and bad fresh die will be investigated along with the bad die which have non-wetting at die top. The surface analysis techniques will be used such as optical microscope and SEM to observe surface morphology. EDX investigation being done to determine the elements presents on the samples surface. Further details information using FIB also been performed. Contact angle analysis to measure the surface tension onto related area and FTIR analysis as support techniques. © 2004 IEEE. |
