Training Experience (1) Electronic technology training is a highly technical basic course, and it is also an important practical link for the science and engineering department of our college to carry out engineering training, learn technical knowledge and improve comprehensive quality. From the second week to the fifth week, I will do this internship for four hours every Tuesday afternoon.
The internship task is to make a multimeter. I didn't know what to do in the electronic technology internship at first. I thought it would be like the previous metalworking internship. Later, I learned that I made the multimeter myself, and I can take the work back. It sounds really funny, so it should be fun to do! In this way, I started this internship trip with great interest and fun.
On the first day of practice, that is, the second week, I watched the scope and technology of electronic technology practice in the video, as well as the high-tech skills of teachers in the video, and I was envious. This afternoon, I had a preliminary understanding of electronic technology practice, a necessary understanding of circuit boards and circuit components, and necessary guidance for my practical operation in the next three weeks.
In the third week, I didn't learn how to make it, but I did some basic work exercises and practiced how to weld resistors and wires with an electric soldering iron. The soldering iron is strange to me, so I take the opportunity of this practice very seriously.
Let me talk about the welding process again. First, insert the prepared components into the designated position on the printed circuit board. After heating with an electric soldering iron, use some proper amount of solder on the cutting edge of the welding head, and the amount of solder depends on the size of the solder joint.
When welding, the cutting edge of the welding head should contact the solder joint and the component lead, and make necessary movement according to the shape of the solder joint, so that the flowing solder can cover the solder joint and penetrate into the gap of the welded object for about 3-5 seconds, and then remove the electric soldering iron. The time, direction and speed of removing the soldering iron determine the quality and appearance of welding. The correct way is to withdraw the soldering iron quickly when leaving the solder joint, and then leave the solder joint quickly, so that the solder joint is bright, smooth and burr-free.
When welding, the welding time should not be too long to avoid scalding components, but it should not be too short to cause false welding or virtual welding. After welding, clamp the welded parts with tweezers and pull them out properly to check whether the parts are welded firmly. If it is found to be loose, it must be welded again.
Welding looks simple, but there are many skills that need to be paid attention to, such as the strength of the side clamp to clamp the wire, the amount and time of solder wire in the welding process, and we can't do more or less! I think the most difficult thing is soldering. I always can't grasp the quantity of solder wire and the time of soldering iron. I think this is a good practice, or I don't understand how many originals I have to weld.
In the fourth and fifth weeks, we started the welding of the last multimeter. I was a little excited to think that the multimeter usually used in the physics laboratory could be welded by myself at this moment.
Practical experience (2) Electrical and electronic practice is my first practice after I entered the second year of college. Of course, when I was a freshman, I was a metalworking intern. Although I have a necessary understanding of internship and experience, I will inevitably make some mistakes when doing electrical and electronic internship. Fortunately, I'm not fighting alone. Our classmates in Class 20xx help each other. From the nine-day electrical and electronic internship, I learned and gained not only the working principle and architecture of the radio, but also how to analyze and solve problems and potential. Of course, in this internship, my class has also become more United and friendly.
During the whole internship, I was deeply touched. From simple welding to complex assembly, I learned that learning and practice are unified and interdependent. Without both, it is impossible to make a radio successfully. Although the course is over, there is no end to learning, and the ocean of knowledge is boundless. I still have a lot to learn. The charm of electronic originals has just begun in my world. Only by continuing to learn and summarize based on the feelings and experiences of electronic practice can we improve ourselves better.
For this internship, my experience is summarized as follows:
1, have a more direct understanding of electronic technology, and have a more comprehensive understanding of amplifiers and rectifier circuits. Although I have disassembled a simple single-tube radio before, compared with this, it is incomparable in principle and actual operation.
2. I have a clearer understanding of the welding procedure, and I am more familiar with the welding methods and skills.
I have made great progress in analyzing and dealing with problems. Because of my blind action at first, I made many low-level mistakes, such as soldering components on the back of printed boards at first, soldering integrated blocks first and so on. With the progress of practice, I deeply realized the importance of analyzing and planning in advance, which I believe people who have not carried out such practical activities cannot understand.
I am experienced in debugging and correcting electronic products. My radio production is really unlucky. From turning on the power for the first time, there was no response at all, and finally I could listen to multiple channels. I have been debugging and correcting errors for many days. After carefully checking every solder joint and analyzing the wiring of the circuit board, I finally solved the problem perfectly.
5. It is very helpful to cultivate the sense of teamwork. Although one hand is holding the soldering iron, there are many brains behind it to command and support it. Let's analyze the circuit diagram and solve every problem in front of us together. It also makes the friendship between students deeper and the class more United!
Experience of practical training (3) In the first week of school, we ushered in the first class of the new semester-electronic technology practical training class. I have a feeling that I can't wait for new courses and new knowledge in the new semester.
This semester, our first contact is a preliminary understanding of electronic components, as well as the structure and layout of the circuit. The most important thing in this training course is the welding seen in daily life. In class, the teacher instructs us on the use of electric welding, because heated electric welding is more dangerous in the welding process. If it is not used properly, it will cause harm to yourself or others. Therefore, we must use electric welding in strict accordance with the relevant regulations and use it correctly to avoid scalding accidents.
When we have mastered the welding methods and skills of electronic components, we can begin to try to weld some circuit board components. The layout of electronic components is very important. Because this is related to the convenience and simplicity of circuit connection.
A short week has passed. In this week, without the guidance of the teacher, our training will be a great failure and the training course can't be completed. Secondly, in this training, I understand that cooperation and communication with peers are very important. Team spirit should be kept in mind. Isn't it a perfect thing to share the joy of success with the same sex?
The training course has gradually come to an end. Through this period of time, we have gained a lot of valuable knowledge, which is inseparable from the hard work of teachers. Here, all my classmates and I say thank you to the teacher!
Practical experience (4) Through this week's practical training, I have learned a lot of knowledge that I have never been exposed to before. Only in this way can we effectively combine knowledge with practice. It also makes us deeply realize that hands-on and theory are inseparable.
In practice, we have learned a lot about electrical equipment and their performances, uses and functions. They bring a lot of convenience to our life. Through practical training, the friendship of the students has also improved a lot, and many experiments that they can't do well have been completed with the help of the students. Through learning from each other, communicating with each other and studying together, we have done many quite successful experiments, and a sense of accomplishment and pride arises spontaneously. The whole training room is full of class unity.
And our conscientious teachers are also busy with us in full swing. Looking at the people around him, he will always patiently explain to us until we understand. So thank our teacher!
Experience of training (5) Through the classroom explanation of the teachers in the training center and the training of enterprise standards, I have deepened my understanding of my major. So as to determine the direction of their future efforts. If you want to learn as much as possible in a short period of training, you need to communicate well with teachers or classmates to deepen mutual understanding. Only by communicating with teachers more and letting teachers know more about us can we really get training. As a result, class culture "* * * pleasure" has gradually formed in life.
"I think it's an armchair strategist. I don't know if it should be done!" In this short time, I deeply felt the lack of professional knowledge in practical application. Let me really understand the meaning of the sentence "endless learning" that the teacher said in the professional understanding week, which is not in the textbook and is very practical for us, adding colorful luster to our training. I understand how professional knowledge is applied and practiced in real life. In these processes, I not only understand the professional knowledge needed for my career, but also deeply understand the importance of cooperation among team members. Being good at teamwork and making good use of the wisdom of others is great wisdom. It is difficult to complete a big project by one force alone. When working as a team, we should listen to the opinions of each member patiently to make our combination more perfect.
This training brought me too many feelings, which made me understand the hardships in my work and the hardships on my career path. Let me understand that the actual work is not as simple as studying at school.
People are not born to know, although my knowledge structure is still very poor at the moment, but I understand that the knowledge to be learned depends on hard work and diligence. Without practice, learning is water without a source and a tree without a foundation. This training made me grow up instantly: we can't stay in the ivory tower forever and live a carefree life. We always have to go to society, and society depends on our younger generation to promote it. This is our experience and feeling of training in different places. Soon, I will face the pressure of employment or further study. I think I should manage my time well, enrich and improve myself, and don't leave any blank in my life! In addition to learning a lot of professional knowledge, I also learned some social realities, including interpersonal communication, communication methods and related etiquette information. For team development, unity makes me deeply understand. Teamwork pays attention to communication and trust, and can't disdain to do small things. We should always be friendly and frank, and apply professional theory to concrete practice, which not only deepened my mastery and application of theory, but also gave me unforgettable development managers again and again, which is also the biggest gain of training.
At the moment, I deeply feel that "a person's greatest wealth is his life experience and network", because it really helps us a lot. Besides, the knowledge in textbooks is limited after all. Through practical training, students in our class have a feeling that there is a big gap between theoretical knowledge and practical work in textbooks, knowledge alone is far from enough, and professional skills need to be improved urgently.
From being clumsy at the beginning to being able to develop software skillfully according to the process at the moment, it is inseparable from the efforts of everyone in my class. Ten months of practical training has taught us a lot, and at the same time, it has also exercised everyone's practical and steady potential. Everyone cherishes this hard-won practical training opportunity.
In practical work, you often deal with different people, but their attitude is not flattering, and you will feel his impatience and arrogance, so you need to learn communication methods and speaking skills and learn to respond flexibly. Through the ten-month training, the students have gained a lot and are satisfied with the training on the whole. Although training is very tiring, I go out early and come back late every day. But I am really grateful to the school for bringing us such a good training opportunity and to Neusoft for giving us a training platform. We deeply understand that only after experience can we appreciate the taste. For me, I like to experience life. I can say that through this training, I really understand what is software development and what is software engineering, and my initial view of software has also changed substantially! Programmers are not only a profession, but also an interpretation of carefulness+patience+responsibility = the value of life. We are about to go to work, and we should constantly strengthen our professional skills. Society will not want a useless person, we should change from a school person to a social person more quickly. To this end, we will continue to work hard in the days to come, constantly inspire our experience, constantly hone ourselves, and take up our jobs as soon as possible.
I recommend it carefully.
