Lead Frame Function of Lead Frame Mold

As the chip carrier of the integrated circuit, the lead frame is a key structural member that realizes the electrical connection between the terminal of the internal circuit of the chip and the outer lead by means of bonding materials (gold wire, aluminum wire, copper wire) to form an electrical circuit. As a bridge to connect with external wires, lead frames are required in most semiconductor integrated blocks, which are important basic materials in the electronic information industry.
