A lead frame is a solderable metallic lead frame in the form of a frame or comb for the machine production of semiconductor chips or other electronic components. The individual contacts ('leads') are still connected to each other, and the frames of the individual products are also connected to each other and are delivered rolled up. In addition, lead frame also describes the shape of the microchips produced with lead frames, i.e. the shapes with (protruding) connections.

Lead frames are mounted on an insulating support or in a housing. If the contacts are mechanically fixed, they can be separated from one another. Lead frames are punched, but can also be laser cut for smaller quantities.
