SAC305 piece + xSb consists of several phases: phase 3 lak -Sn (white) is the phase of Cu6Sn5, Ag3Sn (Intermetallic compounds, IMCs) and Sb portion will melt in the phase of β-Sn.
Workpiece SAC305 + xSb phase consists of three main phases, phase -Sn (white) phase of Cu6Sn5, Ag3Sn (Intermetallic compounds, IMCs) and Sb partially dissolved in the phase of β-Sn.
The target SAC305 xSb consists of the main phase 3 phase is the phase - Sn (white) is the phase of the Cu6Sn5 Ag3Sn (Intermetallic compounds IMCs,,, And some Sb is dissolved in the phase of β - Sn.
