Formation of Ag3Sn plates in SnAgCu solder bumps

solder during phase transformation. Series of such tests performed throughout reflow,
which enables to investigate the entire formation process of intermetallic Ag3Sn plates out
of liquid SnAgCu solder bumps. The results show that Ag3Sn plates are formed first in the
middle of the cooling stage. In the plane, they have two preferable growth directions. By varying thermal conditions during reflow, the formation mechanism of these plates is
discussed.
