Description

Technical Field

[0001] The present invention relates to the technical field of semiconductor processing, and in particular to a field effect tube packaging mechanism. Background Art

[0002] In today's era of rapid development of electronic technology, field-effect transistors (FETs), as extremely important semiconductor components, occupy a core position in many electronic devices and systems, and are widely used in communications, computers, consumer electronics, automotive electronics and many other fields. As these fields continue to expand and upgrade, the demand for FETs has exploded, and more stringent requirements have been placed on their performance, quality and production efficiency. In the process of miniaturization and high performance of electronic devices, the packaging process of FETs has become a key link, so a FET packaging mechanism is designed.

[0003] Existing field-effect transistor packaging devices have exposed many problems in practical applications:

[0004] First, the chip delivery process is severely under-automated, often relying on manual operation or semi-automated equipment. This not only leads to low production efficiency but also makes it difficult to ensure the stability and accuracy of the chip delivery process.

[0005] Secondly, there are serious design flaws in the suction nozzle, a key component for adsorbing chips. When the suction nozzle needs to be replaced, due to the lack of an effective protective mechanism, the suction nozzle is very likely to accidentally fall into the machine. Once this happens, the suction nozzle may be stuck in the machine's precision transmission parts or other key structures, directly causing the machine to jam or even damage the internal parts of the machine. This will not only cause the equipment to be shut down for maintenance, consuming a lot of time and manpower costs, but will also seriously affect production progress and cause huge economic losses to the company.
