Abstract
PURPOSE: To conduct the partial plating of a frame accurately and inexpensively even if the frame has complex patterns by coating each frame part requiring no plating with a resist film for a plating process together with the edge part and removing the resist film after the plating process.
CONSTITUTION: Various kinds of patterns which are not for mass production are provided to a substrate (a) to form an IC lead frame (b). Ink for a resist film with ductility and resistance to a plating soln. is applied to a part 5 of the frame (b) requiring plating from both sides, and the whole of each part 6 requiring no plating is coated with a resist film 7 for a plating process together with the edge part 9. After passing through the following plating process, the resist film 7 is removed from the frame (b).
