ABSTRACT:
An IC packing device comprises a semiconductor device, a piece of flexible resin film provided with an opening for receiving the semiconductor, wires arranged on the piece of flexible resin film and slits cut into the piece of film from the edges of the opening. The slits cut into the flexible resin film allow the film to be flexed downward toward the semiconductor, along with the wires which to establish electrical connection with the semiconductor. In this manner, the downwardly bent flexible film provides reduction in the possibility of a wire breaking due to excessive bending of the wire in order to make contact with the semiconductor.
