Engineer's internship summary

Engineer's Practice Summary (5 Selected Articles)

The hard and meaningful internship life is over again. Looking back on the past internship experience, I have gained a lot. At this time, I need to write an internship summary. Is it impossible to write without a clue? The following is a summary of the engineer's internship (5 selected articles) that I helped you organize for your reference, hoping to help friends in need.

Summary of engineer's internship 1 The short week will soon be over. In these five days, I learned something that I didn't learn in four years in college. Including process flow, production process requirements and basic knowledge learned in the prototype unit.

Process production flow. The company's main products are LED driving power supply and other driving power supplies. The main production part of driving power supply is the production of electronic circuit boards. Firstly, the electronic circuit board was designed and developed by R&D department, and the appropriate components were tested. Then hand over the whole design scheme to the relevant personnel in the engineering department. The engineering department submits the product list to the sample unit, and the personnel of the sample unit will prototype the components, the circuit board that has passed the SMT production process, and the assembly parts required for the whole driving power supply. The prototype unit has completed the trial production of new products through several parts, such as component assembly, wave soldering, product assembly, glue filling and testing, and obtained the relevant data of new products. Relevant personnel of the engineering department will evaluate the test data of the sample unit, analyze whether the new product can be used for production, and if so, put the new product into the production line. In the process of production line, it is necessary to analyze abnormal mass production to improve the first pass rate of production line. The main duties of PE assistant engineer are: new product introduction, trial production tracking, mass production exception handling and problem point tracking, improving the first pass rate of production line, handling customer complaints and defective product analysis, and assisting PE engineer to complete daily work.

Production process requirements. The design of each component on the circuit board is a design scheme obtained through very rigorous analysis and continuous testing. In the production process of the production line, every problem needs to be solved in the production process, such as the pin length of components, the direction of components, whether components need to be glued, whether components need to be bridged on the circuit board, and whether pins are soldered or soldered. In the production process, the influence of human factors is the greatest. The production line needs to reduce human factors and improve the first pass rate of production.

Learning sample unit. These days, I mainly understand the product production process, and have some understanding and understanding of product performance, component composition, preparation and matters needing attention in component assembly.

1. Before the circuit board is delivered to the sample set, some components of the circuit board will go through the pasting process, and the pasted components will be pasted on the circuit board with red glue.

2. Before assembly, the product needs to be trimmed. If the component foot is long, it will scratch the tin furnace during wave soldering, and if it is short, it will not be able to pass wave soldering. Components need K-pin and bridging, so they need to be adjusted according to the design of the circuit board. Some components, such as transistors and capacitors, need to be added with magnetic beads, which play the role of inductance.

3. Plug-in is the next procedure after foot cutting. Insert components in different positions according to the work order requirements, and pay attention to the direction of components, such as diodes, triodes, aluminum electrolytic capacitors, etc.

4, check the welding effect after welding, and deal with the phenomenon such as virtual welding, missing welding, components not protruding, so that the whole line is error-free. Input and output wire welding, power supply shell assembly.

This week, the follow-up work of the new product of the sample unit ended with the external assembly of the product. The knowledge learned is roughly in the above aspects, so I won't list the details one by one. I hope I can learn more knowledge in the future and get familiar with the product performance of the company as soon as possible. The learning process needs to pay attention everywhere, always care, think more and communicate frequently. I will ask more colleagues in the engineering department, hoping to be competent as soon as possible.

Engineer internship summary 2 During the internship, Mr. xxx will lead the maintenance and installation. A lot of maintenance, repair and installation have been carried out. In these processes, I have accumulated a lot of practical work experience. Basically, all the questions were completed under the guidance of teacher xxx. Under the careful and patient guidance of teacher xxx, I personally feel that my theoretical and technical knowledge and practical operation ability have been greatly improved, and my handling of some details and customer communication have also been improved accordingly. I learned a lot from teacher xxx in all aspects. First of all, technically speaking, individuals have been able to complete general maintenance independently, and must have certain fault judgment and maintenance experience accumulation. In the new installation, both physical positioning and electronic installation can be done independently. The following is a brief summary of the maintenance process:

1. Determine the fault location according to the fault phenomena provided by customers.

2. Confirm the fault location. You can check it on the spot or check the error code together. Fault must be accurately judged. Only in this way can the problem be fundamentally solved.

3. According to the fault location, the corresponding maintenance methods are given. Never be careless and perfunctory. In order to avoid repeated failures and leave a bad impression on customers.

4. Training during the new installation is also very important. Good training can bring great convenience to future work. It can also reduce a lot of unnecessary troubles.

5. Regular maintenance of the machine every month can effectively reduce the failure rate.

6. Good technology is always the foundation of good service.

For some common problems of the machine, Teacher xxx gave us a summary and classification, and gave common simple methods one by one. For example, there are often various reasons and solutions for withdrawing money, as well as some common error codes, which are summarized in great detail and I have learned a lot from them. More importantly, let me know that to do a good job, we must constantly learn and summarize.

In terms of service attitude and communication with fishermen:

1. Customer service mainly deals with customers, and politeness and image are particularly important. After all, the individuals outside represent the image of the company.

As a quasi-employee, you must have excellent skills first, which is the basis of service. Keep in mind that "technology is the survival means of customer service"

Secondly, pay attention to your ability to communicate with customers. Good communication skills can make our work more handy.

4. The problem of machine lock should be clarified and the solution should be clear. Explain clearly to customers, try to answer questions, and apologize to customers in time when you are uncertain.

Although the work of customer service is based on technology, communication with customers is also a very important link. It can also bring more convenience to our work.

During the three-month internship, I increased my theoretical knowledge and practical ability. Of course, I have encountered many problems and made mistakes. I realize that I still have many shortcomings. I know I still have a lot to learn and explore. I will study and work harder in the future and make myself an excellent customer service engineer as soon as possible. Able to handle machine problems and failures for customers independently, quickly and more satisfactorily. The needs of customers and companies are the direction of my efforts.

Summary of Engineer's Internship 3 My internship unit is a college, which is a full-time secondary specialized school that cooperates with the Municipal Education Commission, (Group) Company and German Foundation to explore and practice the "dual system" vocational education model in Germany. I am mainly responsible for the management of the campus intranet at school, which involves the normal login and access of the campus website, whether the hosts of various departments in the campus are interconnected normally, and whether they are infected and spread by viruses. Make the computers in the campus network run normally, and do a good job in the management and maintenance of the campus network.

From a student to an intern engineer, I have benefited a lot from just a few months' work. Not only in professional knowledge, but also in dealing with people. The society is changing rapidly, and the demand for talents is getting higher and higher. To look at problems from a developmental perspective, we must constantly improve our ideological understanding and ourselves. As an it practitioner, the social pressure will be heavier than other industries, so we should learn to innovate and change to meet the needs of society. In the company, from the assembly and maintenance of computers to the maintenance and testing of servers, everything needs to be done by one person independently. It can be said that these three months of work have made me grow a lot, and I have gained a lot of insights from it. The following is my little experience:

The first is sincerity: you can disguise your face and your heart, but you should never ignore the power of sincerity. On the first day of internship in the network center, I inevitably wondered: I don't know what the teacher is like, what should I do, what should I do, and so on! When I walked into the office, I saw some strange faces. I greeted them with a smile. From that day on, I got into the habit of saying "Good morning, teacher" with a smile every morning when I saw them. This is my sincere greeting. I always feel that there are often some subtle things that are easily overlooked by us, such as a gentle greeting, which expresses respect and concern for teachers, colleagues and friends, and also makes others feel valued and concerned. In just a few days, I became one with the teachers and communicated well. I think it should be my sincerity that won the trust of teachers. They regard me as a friend and are willing to guide me and assign me tasks.

The second is communication: if you want to learn as much as possible in a short internship, you need to have good communication with teachers and deepen mutual understanding. When you first arrive at the network center, the teacher doesn't know your work and learning ability, what you will do or what you want to know, so it is necessary to communicate with the teacher well. At the same time, I think this is also an indispensable key for us to step onto the society in the future. Through communication and understanding, the teacher gave me a general understanding and taught me some targeted knowledge. I am interested in network wiring, computer hardware installation, network troubleshooting, and application of working principle, so the teacher asked me to independently complete network maintenance and computer troubleshooting in all departments of the school. For example, the components of the secretariat office LAN and the server monitor in the central service room directly or indirectly ensure the normal operation and use of the campus network. In this work, we really learned the knowledge that is not available in the computer textbooks, consolidated the old knowledge, mastered the new knowledge, and even acquired the unrealistic old knowledge in the books in practice, which truly reflected the real value of knowledge and applied what we have learned.

The third is passion and patience: passion and patience, like fire and ice, seem completely different, but they can collide with the most beautiful sparks. When I was in the center, the teacher told me that passion and patience are essential to make a computer network. In terms of product renewal, this industry is like doing news work to make up for the renewal, which requires you to learn and improve your professional level with passion and patience. The same is true in some specific work: I remember that when I first came to the school for internship, the teacher arranged for me to install win98 operating system in the general department. I thought it would be easy for me, but I didn't expect many problems. At first, it was a hardware problem: the CD-ROM drive didn't work, which made me impatient when I first installed the system, and then after it was solved smoothly, the driver problem of the 98 system made me nervous!

It took me two whole days, from slowly installing the USB drive to checking the hardware model through hardware monitoring software, and finally successfully installing the system. From then on, I really figured out the hardware installation, maintenance and update of the computer. Then repeatedly installing and debugging various computer operating systems is naturally annoying, but I overcame these difficulties with my enthusiasm and patience and consulted my teacher. These are only acquired from ordinary books, and the perceptual knowledge that has really been practiced here is truly proficient. It also made me realize my own shortcomings and warned myself not to be arrogant in whatever I do, but to be good at learning.

There is also a look at the log records, which impressed me deeply, because the maintenance of the server is complicated and arduous, and it is necessary to ensure both physical security and system security. This requires querying the log log records. The status of the server has a log log record every minute, and it has a large amount of data and a lot of useless information, so it is "painful" to query the log. I deeply feel that I can't do such a job with passion and patience.

Summary of Engineer's Internship 4 In a blink of an eye, I have been in the company for almost a month. From the campus to the internship, the learning environment has changed, and the relationship with the people around you has also changed. At the beginning, the most important thing is to change roles and integrate into the environment. It is a very important role change from school students to company employees, and it is also a leap in life. For college students, this is not an insurmountable obstacle, and internship opportunities will also be a springboard for my future career. In the adaptation stage of internship, my most important change is the change of attitude, and I also realize that attitude is everything. As a newcomer and joining a new team, attitude is the most important thing to pay attention to. Have the habit of studying, reflecting and reviewing this week's study;

As a Java development engineer, Java virtual machine must be familiar with its memory partition and working principle, so this week I spent some time reading the specification document of Java virtual machine, learning the mechanism of classloader, and being familiar with the memory partition and various parameters of virtual machine. First of all, what is the class loader mechanism?

When we write a Java program, whether it is a CS or BS application, it is a complete Java application organized by several organizations. Class file. When a program is running, it will call an entry function of the program to call related functions of the system, and these functions are encapsulated in different class files, so it is often necessary to call methods in another class file from this class file. If another file does not exist, it will cause a system exception. When the program starts, it will not load all the class files used by the program at one time, but dynamically load a class file into the memory according to the needs of the program, so that only after the class file is loaded into the memory can it be referenced by other classes. So ClassLoader is used to dynamically load class files into memory.

The Java virtual machine provides a three-tier class loader.

Bootstrap classLoader: implemented by native code, it is a part of JVM and mainly loads classes needed by JVM itself, such as java.lang, java.uti, etc. These classes are located in $ java _ home/JRE/lib/rt.jar. Bootstrap ClassLoader does not inherit ClassLoader, because it is not an ordinary Java class, and its bottom layer is written by C++ and has been embedded in the JVM kernel. When the JVM is started, the Bootstrap ClassLoader is also responsible for loading the core class library and constructing the extended class loader and the App class loader.

ExtClassLoader: an extended class loader, which loads the extended jar located in the $JAVA_HOME/jre/lib/ext directory.

AppClassLoader: system classloader, the parent class is ExtClassLoader, which loads the directory and jar under $CLASSPATH, and it is responsible for loading the main function class of the application.

In fact, knowing the mechanism of class loader, I personally think it is more important to learn to customize class loader. Why learn to customize the class loader?

The class loader provided by JVM can only load jars and classes in the specified directory. If we want to load classes or jars in other places, such as loading a class file on the network, the default class loader can't meet our needs, so we need to define our own class loader.

Engineer internship summary 5 Hello! Because the company is busy recently, I haven't had time or settled down to write an internship summary. I hope this late summary will satisfy the teacher.

Just entering the society, I feel excited, nervous and sad. I am excited that I can finally grow up and start a real life; I am nervous about whether I can adapt to this society and overcome this new environment; Sadly, I will end this innocent student life from now on. Inner contradictions, thoughts turned upside down.

I am now working in xxx Technology Co., Ltd., and I am an operation and maintenance engineer. I have been in the company for more than half a month, and I have really felt a lot in this half a month. Talk more, talk more, talk less, talk less for more than half a month! Too much talk is enough to be familiar with the company's working system, working environment and workflow, but too little talk is far from being familiar with the company's network architecture and technical services. I also need my own continuous efforts to enrich myself technically and become a qualified company employee.

Over the past half a month, I have gradually become familiar with the company's working system and working environment. It is too early to say whether I am fully qualified for this job. I can't brag or say irresponsibly that I can finish the task well, even if I say so, no one will believe me (haha-...). Looking back on the past half month, I haven't really finished the task assigned to me by the company independently. Having said that, I haven't said what I have done since I came to the company. Now it's time to introduce what I mainly did during my stay in the company.

When I first joined the company, the company organized a week-long training for newcomers. The training content mainly introduces the company's workflow and matters needing attention in work, as well as a brief introduction to the company's network topology and network configuration. Even this simple introduction made me find that there are too many things I can't learn and there are still many things to learn!

During the time when I came to the company, the main thing every day was to be familiar with the network structure and configuration of the company and practice the installation of the server operating system. The system installation here is not simply to install the system, but to practice installing different operating systems according to the different needs of customers. The installed operating system is not only windows2003 or liunx, but also freebsd, centos and other operating systems that we have not touched. Because of the different needs of customers, the systems to be installed are also different.

For those who haven't practiced in school for the first time, it is very difficult to install the server system, so it is even more difficult for us to troubleshoot the server. Troubleshooting requires a person to have enough practical experience and be familiar with common faults in practical work, which a freshman does not have. I will not be discouraged in the face of immediate difficulties. On the contrary, I will study harder, constantly arm myself with knowledge, integrate myself into the company as soon as possible, be competent for the tasks assigned to me by the company as soon as possible, and become a qualified employee of the company as soon as possible. Let me introduce my duty first.

When I was on duty for the company for the first time, I was still a little nervous. Although the company had informed us that there were several new people on duty before the handover, and I made corresponding preparations in my heart, I didn't expect that I was the first on duty. In the face of the sudden notice that day, I was still on duty that day, which was unexpected and made me feel at a loss.

I'm afraid I can't deal with the problems I encounter. I'm afraid I'll make mistakes. Fortunately, with the help of my colleagues, I finally successfully completed the duty task. Let's talk about the main task of duty. Sounds simple, just monitoring the network. If it is found that the customer's machine can't ping or the packet loss is serious, notify the customer service and ask the customer service to inform the customer.

However, before notifying the customer service, we still need to determine whether the customer's machine is blocked or the packet loss is serious, which is a problem of our company's network, the public network or the customer's own network. This requires us to notify the customer service after judgment. And these are all things that I am not familiar with and need to learn by myself.

Finally, briefly summarize the problems I encountered in the company:

1. The customer reported that there was a particularly large delay and packet loss in a computer room.

Analysis method: First, log in to other testing machines (telecom, Netcom) to do a ping test to see if the delay is large. If the delay is really large, please conduct a tracert test to analyze which hop the delay starts to increase. If the tracert results show that the delay increases from the middle position, it can be judged that the problem occurs in the backbone network. If it is found in the tracert results that the delay increases from the last hop, it can be judged that there is a problem in the computer room.

2. The customer complained that the machines in the computer room could not be connected.

Analysis method: First, personally connect the customer's machine. If not, analyze the situation from the network aspect first. First, ping whether the gateway ip of this machine can be connected. Answer: If yes, this section of the network is normal, and then judge whether this server is down, whether there is a problem with the network cable (check whether the network card indicator is normal), and whether there is an arp spoofing attack (which can be solved by binding the mac address). B: If it doesn't work, log on to the testing machine in other places for tracert test, check which jump doesn't work, and then find out the cause of the problem.

3. The hard disk cannot be found when reinstalling the system.

1. There is no physical hard disk device.

2. Hard disk cable connection problem

3. The hard disk controller driver is not installed or the driver does not match (find the corresponding driver).

Internship is an important stage to lay the foundation for the future. Cherish every job opportunity, no matter who you are, what degree you have, what job you are engaged in, show your ability well and don't miss the good opportunity. Nothing is easy, but everything makes people grow, and they have to go through a process, joy or hardship. Although the way of experience is different, the result is the same, and we will all grow up because of the things involved.

The above is my experience these days. I hope the teacher can correct and guide my shortcomings. Thank you!
