Figure 9
IPF maps and IPF density of β-Sn solder in the second specimen before and after the thermal cycling. IPF (xs, ys, ND) maps and their densities before thermal cycling are illustrated in (a)–(f). IPF (xs, ys, ND) maps and their densities after thermal cycling are illustrated in (g)–(l), respectively. Noticeable orientation changes are observed, especially in the IPF (ND) map. After the thermal cycling test, the a axis tended to align parallel to the specimen ND, and smaller fractions of grains exhibited alignment of the c axis or the [221] direction parallel to the ND. In the case of IPF (xs) and IPF(ys), weak texture components at the [112] direction, and between the [011] and the [021] directions are observed. The orientations of selected individual grains (A, B, C, and D) before and after thermal cycling are shown in (m) and (n), respectively. |
