Objet: Re: [LF] Failure mechanism of Sn-Ag-Cu


Dear Mr Quadir, dear all,

Late reaction because of summer holiday. Sorry!

In the BRITE/EURAM project IDEALS we found the following degradation modes
for various alloys:
SnCu eutectic:  cell boundary fracture; virtually no intergranular
deformation
SnBiAg alloy:  ibid
SnAgCu eutectic: intergranular as well as cell boundary deformation,
comparable ti tin-lead eutectic.
More details will be presented during the second week of September in Europe
Goes Green - Berlin Germany and in IPCWorks 2000 in Miami.

Regards, Erik

Classification: Restricted
Hi All,

I was wondering if anybody on this list has worked on failure mechanism
of the above solder alloy due to thermal cycling. Some initial work done
in my institute suggest that SAC alloy has trans-granular failure and
not inter-granular failure as in Sn-Pb solder.
I hope somebody can confirm this result.

Thanks and Regards
