Compared to DC plating, Sn plating films prepared using periodic reverse current(PR)were more effective at suppressing whiskers induced by external stress. Results obtained by XRD confirmed that they had almost entirely non-oriented structures and strong oxide films. However, the strains of both DC and PR plating were similar. The internal stresses were much weaker than the external stresses.
