Description

Technical Field

[0001] The utility model relates to the technical field of lead frames, in particular to a high-matching folding lead frame. Background Art

[0002] As the chip carrier of integrated circuits, the lead frame is a key structural component that uses bonding materials (gold wire, aluminum wire, copper wire) to achieve electrical connection between the internal circuit lead ends of the chip and the external leads to form an electrical circuit. It serves as a bridge to connect to external wires. Lead frames are required in most semiconductor integrated blocks and are an important basic material in the electronic information industry.

[0003] The lead frame is generally placed in an electrical appliance housing. Due to the limited space in the electrical appliance housing, when the lead frame is long, it is easy to make the lead frame difficult to install in a shorter electrical appliance housing. At the same time, the electrical appliance housing has a certain thickness, and the thickness of the lead frame is relatively small, resulting in the thickness of the electrical appliance housing cannot be fully utilized, which is not conducive to the installation and use of the lead frame.
