A method of manufacturing a lead frame and a clip frame

Abstract

A method of manufacturing a lead frame and a clip frame in a combined process, comprising the steps of: providing a sheet material; stamping the sheet material, thereby removing residual material, creating an array of a plurality of flat frame layouts, the array having a first array direction and a second array direction perpendicular to the first array direction, each flat frame layout consisting of lead frames and clip frames, the plurality of flat frame layouts interconnected by connecting bars extending along one array direction; bending the array of a plurality of flat frame layouts to create an array of a plurality of bended frame layouts along one or more bending lines parallel to the one array direction; singulating the bended frame layouts from the array of bended frame layouts.
