Nickel is commonly coated on the outer leads for T8 metal package. The leads electrodeposited by conventionaldull or bright nickel over 5μm at direct current from Watt bath are hard to pass the bend fatigue test for three times. Nickelelectrodeposited at multi waveform current including direct current, single and double pulse from sulfamate bath can im-prove the bend fatigue strength of leads. Such nickel plating has a multilayer structure, its morphology of sublayers can beclearly seen in its cross section with SEM. The electrochemical study shows that these sublayers have different corrosionpotentials. The bend fatigue test of leads with such plating for T8 metal package shows that the number of bend increaseswith the decrease of average current density of multi waveform, which can be attributed to the reduction of every sublayerthickness and the increase of layer numbers under the same condition of total thickness.
