In this paper we investigate the appropriate reflow profiles for simulated CSP solder joints using Sn-Ag-Bi-In solder, which has a lower melting point than Sn-Ag-Cu solder. We have examined the relationship between the interfacial microstructure and

A stacked device called SEP (System Embedded Package) was developed to drastically increase LSI density relative to its area on the circuit board. This was achieved by fabricating an LSI package in a stacked structure. This device has been applied to
