A method for forming a plating layer of a lead frame having excellent anti-corrosion properties is provided. At least a portion of a lead frame is plated, then a first heating of the plated portion of the lead frame to a first temperature is performed, and finally a second heating of the first heated plated portion of the lead frame to a second temperature higher than the first temperature is performed. The lead frame manufactured by this method has excellent anti-corrosion properties, such that deterioration of the plating layer, by cracking and inferior solderability, is not observed. |
