On April 16, 2018, the joint training base for college students of Xi'an Semipower Electronic Technology Co., Ltd. welcomed a new batch of students for student internship courses here. They are 25 students in the excellence class of integrated circuit design and integrated systems. The development of this course received great attention from Vice Dean Mr. Zhang Jincheng and Mr. Luo Yi, Chairman of Semipower. They held discussions and reached consensus on the following aspects.
1. Semipower has carried out joint training courses for nearly five years. Teachers and classmates said the results were very good and helped the school make outstanding contributions in talent cultivation. They expressed their gratitude;
2. Semipower currently has a relatively complete training program for excellence classes and postgraduate internships. On this basis, the two parties discussed how to effectively use resources to closely combine theoretical classes and practical classes for the current more than 500 undergraduate students in a grade, and arrange well for 2018. joint courses;
3. Regarding the new energy vehicle power control power supply research center project to be built by Semipower, it is closely related to the research on third-generation semiconductor (GaN, SiC) power devices. Although the strongest in the third-generation semiconductor is GaN microwave devices and circuits , but there is also a lot of accumulation in SiC power electronic devices, GaN power electronic devices and their power modules, and the two parties can certainly conduct in-depth cooperation together.
4. In the future, both parties will work together to organize various industry seminars and try their best to leverage the superior resources of both parties.
In its actual development, Semipower pays special attention to the joint training of students with schools. Each teacher has strict requirements in advance, actively prepares lessons, explains carefully, and evaluates in a timely manner, and takes "having knowledge, being able to apply, and being able to think" as the training requirements. basic requirements. This training includes three modes: on-site visit learning, theoretical learning, and operational practice learning:
On-site visits and learning, students are invited to the laboratory to get close contact with the equipment and experimental environment. At the same time, the supervisors of the Semipower laboratory introduced each test equipment in the four laboratories of the center one by one, and explained in detail the detection and experiments of chips to power products. Analyze the rigorous testing process and introduce the existing analysis and testing capabilities of the test application center and the upcoming testing directions;
Theoretical learning is mainly taught by front-line employees in the laboratory, and they understand the laboratory, packaging process, thermal resistance testing technology, MOSFET Datasheet, reliability basics, development and structural evolution of power devices, IGBT module packaging and testing, SW2601A project design introduction, etc.;
Operational practice learning mainly includes basic identification of electronic components, self-built circuit testing of MOSFET static parameters, charger sample production precautions, circuit board welding test exercises, sample production and final sample evaluation test and comments.
The five-day internship course on April 20th was a complete success. Through on-site visits to the Semipower Test Application Center, students in the Excellence Class gained a deeper understanding of the basic methods of laboratory testing and the principles of advanced equipment testing technology through a combination of theoretical study and hands-on operations. At the same time, the training students spoke highly of Semipower's R&D level, laboratory testing capabilities and product execution standards.
Through this internship, I gained a lot. This internship was a good opportunity for me to apply the theoretical knowledge in the book into practice. I also learned knowledge about packaging and testing that I had not touched in the classroom before. On the other hand, it also improved my ability to do projects by myself. ability. Through the detailed introduction by the laboratory teacher, I briefly understood the functions of various equipment. Unfortunately, due to the short time, I did not have the opportunity to learn the operation of large instruments and how to deal with problems that arise in instrument testing devices. (Wang Yang)
I recently interned at Semipower for a week and benefited a lot. I further understood the principle knowledge learned in school and was able to combine it with practical applications. I also learned about some technologies and improvement ideas in actual production, and also learned testing principles and other knowledge, which will be of great help for future study. help. At the same time, we visited the test laboratory, system laboratory, etc., and learned in depth how to use some instruments. The one-week internship has come to an end quickly, thank you for this interesting and meaningful opportunity! (He Xu)
My internship at Semipower was the first time I walked into a company and experienced its culture and operations first-hand. Thanks to Semipower, I have had a completely different experience from what I had in school. In the process of studying in school, most of the students’ knowledge comes from books. There are so many various experiments that we cannot understand each experiment in detail. The details of a device. At Semipower, their research on the products they produce is truly in-depth and thorough. From design and development, to tape-out and packaging, to various testing for a device. The teachers in the laboratory are serious and demanding. These are things that cannot be experienced on campus. For laboratories, the performance of the device may be the first priority, but considering emergencies in practical applications and the reliability of the device, this should also be the company's priority for the device. Reasons to ask for more. This will also be a key factor that I need to consider as a researcher in the future.
When making a charger by myself, the school's requirement is just to make it and be able to use it normally. But the requirements in Semipower are much stricter than normal use. Not only do we make a simple finished product, we also test the finished product, with a page full of data to verify its reliability, to ensure that the charger can be used without fear of various unexpected events. situation. Although we finally tested only part of it, we have not yet done more environmental simulation tests. However, this kind of testing environment and even testing methods are not available in schools. We have learned a lot from our studies here, and we have learned a lot from them. (Sun Xinhao)
