Abstract:
Improvement in shock-resistant strength of a soldered joint is aimed at, and the variation in the plating film formed on an electrode pad is reduced.In the step which forms a plating film (for example, Ni film) by an electrolytic plating method on the surface of an electrode pad, the first layer is formed in the front surface of the electrode pad with the first current density, and the second layer is formed in the front surface of the first layer with the second current density higher than the first current density after that.
