PROBLEM TO BE SOLVED: To provide a method for manufacturing a lead frame capable of preventing a steep rise in a manufacturing cost based on use of silver plating containing noble metal by suppressing silver plating usage during manufacturing as much as possible, with regard to a method for manufacturing a lead frame for an LED package.SOLUTION: A method for manufacturing a lead frame includes the steps of: creating a lead frame bar by forming a lead frame pattern on a metal bar; applying partial plating only to an upper surface of the lead frame in the lead frame bar; and applying highly-glossy silver plating to an upper surface of the partial plating and the whole surface of the lead frame bar. |
