  • Methods and apparatus to reduce growth formations on plated conductive leads
    Patent number: 7368326
    Abstract: A process includes annealing one or more plated conductive leads at a predetermined temperature. The one or more plated conductive leads are plated with one or more layers, where each layer comprises a material. The predetermined temperature is greater than or equal to approximately a melting point of one of the materials. The annealing can reduce growth formations, such as whiskers, on the one or more conductive leads. Lead frames and other devices having plated conductive leads may be subjected to the process, and the resultant plated conductive leads will have fewer growth formations than plated conductive leads not subjected to the process. The plated conductive leads may be trimmed and formed prior to or after the anneal.
