Abstract
A method for making a lead frame comprising overflow plating the lead frame to form a plating layer thereon; and heating the plated lead frame at a predetermined temperature to rearrange the plating layer. Therefore, the rearrangement of the overflow-plated lead frame, by thermal treatment, effectively eliminates the number of pores formed in the plating layer of the lead frame, thereby greatly reducing the number of corrosive portions.
