Description

A turntable lead frame detection device

Technical Field

The present disclosure relates to the technical field of automation equipment, and in particular to a turntable lead frame detection device.

Background technique

Lead frame is a structural carrier. As a special bonding material for semiconductor and microelectronic packaging, it is a key structure to form an electrical circuit. As a bridge connecting the internal circuit with the external wire, the lead frame plays a role in stabilizing the chip, conducting signals, and transferring heat. Lead frame is required in most semiconductor integrated blocks and is an important basic material in the electronic information industry.

Copper alloys for lead frames are roughly divided into copper-iron, copper-nickel-silicon, copper-chromium, copper-nickel-tin (JK-2 alloy), etc. Ternary, quaternary and other multi-component copper alloys can achieve better performance and lower cost than traditional binary alloys. Copper-iron alloys have the most grades and have good mechanical strength, stress relaxation resistance and low creep properties. They are a good type of lead frame material. Generally, in the production and processing of lead frames, lead frame detection equipment is required to perform optical detection on the lead frames.
