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 tubes, 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. With the continuous expansion and upgrading of these fields, the demand for field effect tubes has exploded, and more stringent requirements have been put forward for their performance, quality and production efficiency. In the process of miniaturization and high performance of electronic equipment, the packaging process of field effect tubes has become a key link, so a field effect tube packaging mechanism is designed.

[0003] Existing field effect tube packaging devices have exposed many problems in practical applications: First, the degree of automation in the chip delivery process is seriously insufficient, often relying on manual operation or semi-automatic equipment, which not only leads to low production efficiency, but also makes it difficult to ensure the stability and accuracy of the chip delivery process; 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 get stuck in the machine's precision transmission components or other key structures, directly causing the machine to get stuck or even causing damage to the machine's internal parts. This will not only cause the equipment to shut down for maintenance, consuming a lot of time and manpower costs, but will also seriously affect production progress, causing huge economic losses to the company.
