    Abstract: A manufacturing method for a composite metal wire used as semiconductor packaging wire and products thereof. Au, Ag and Cu materials are melted in a vacuum melting furnace, and then trace metal elements are added into the vacuum melting furnace and melted together with Au, Ag and Cu materials to obtain a composite material. The obtained composite material is drawn by a fist thick drawing machine, a second thick drawing machine and a first thin drawing machine to obtain a composite metal wire with a predetermined diameter. An Au layer is electroplated to the surface of the composite metal wire. The composite metal wire with Au layer is then drawn by a thin drawing machine, a very thin drawing machine and an ultra thin drawing machine to obtain an ultra thin composite metal wire with a predetermined diameter. Finally, the surface of the composite metal wire is washed and the composite metal wire is heat treated to ensure a final product with desirable physical properties, e.g. breaking load and elongation.
