etched lead frame

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

Benefits of Photo Chemical Etching

high lead density,high conductivity ,high precision ,ultra-fine tolerance

Ultra smooth and clean surface without burrs and stress
