METHOD FOR PROTECTING LEADFRAME, LEADFRAME COMPOSITE, BOX AND OUTSIDE CONTAINER

A method (10) for protecting leadframe, a leadframe composite (20), a box (26) and an outside container (34) are provided. The method (10) includes: step (12), providing a leadframe (22) of a first standard electrode potential; step (14), providing a protection material (24) of a second standard ele...

Beschreibung
Zusammenfassung:A method (10) for protecting leadframe, a leadframe composite (20), a box (26) and an outside container (34) are provided. The method (10) includes: step (12), providing a leadframe (22) of a first standard electrode potential; step (14), providing a protection material (24) of a second standard electrode potential, the second standard electrode potential being lower than the first standard electrode potential; and step (16), contacting the protection material (24) with the leadframe (22) so that the protection material (24) acts as a sacrificial anode to protect the leadframe (22) as a cathode from corrosion/oxidization. Embodiments of the present disclosure may help to protect the leadframe (22) without changing the alloying condition of the leadframe (22), without increasing the processing cost of the leadframe (22), etc.
