4. Condition
If reflow, IMC layer occurs between the solder ball and substrate. IMC layer's composition changes depending on reflow time.
Temperatuer
255℃
Reflow time
1s, 1min, 5min, 10min, 20min
<Table 2> Experimental conditions
5. Analysis
IMC layer change was observed according to the reflow time.(Reflow time : 1s, 1min, 5min, 10min, 20min). Do refer to <Table 3>.
Reflow time
IMC layer
SEM micrographs
1s
(Ni,Cu)3Sn4
<Table 3> The SEM micrographs of the Sn–3.5Ag–0.7Cu/Ni interface reflowed at 255℃
