The growth history of technicians who have been engaged in SMT work for 10 years
In the blink of an eye, I have been engaged in the SMT industry for nearly 10 years, from a young man in his early 20s to an elderly working man in his 30s! For the SMT industry, I have a sense of belonging to SMTHOME. I once invested in this industry with high enthusiasm. I once imagined that I could carry a bag and go to various factories to repair equipment and become a manufacturer. What a happiness and pride; How to forget about an equipment problem; once madly reading through various craft magazines and craft books; once used the pleasure of mastering knowledge to solve one craft problem; once after the financial crisis, there was a manpower crisis, and the efforts made for it .
In the past ten years, there have been gains and omissions, joys and sorrows. Pack up and get back on the road! It was 2001. NOKIA 8210/8250 mobile phones were very popular (now many people probably forget NOKIA), hehe I just bought it yesterday. IPONE4S. At that time, I had just graduated from the technical secondary school and I was going back to Nanjing, because many of my classmates came to work in Suzhou. I thought it was fun. I also passed an interview at the school and passed an interview with an EMS company in the park, and started my future life! On October 15, 2001, I remember this day as clearly as my birthday. I came to an EMS company in the park to report that I lived in a 3-bedroom house rented by 8 classmates. The TV was playing 24 hours a day. At that time, it was just in time for the top ten in Asia. At the end of the move, the TV (peacock brand) was broken and the landlord lost 50 RMB. The conditions are naturally more difficult, and I still have a very happy time in retrospect! (Because of simplicity and joy from the heart!) After entering the company, I was assigned to the plug-in line. At that time, I was very happy. The reason is simple: my station is to print labels for PHS, and I use Fujitsu notebooks. The notebook is very advanced for me! This situation didn't last long. The dot-com bubble crisis came, and orders for production lines dropped sharply and were often turned off. Fortunately, the line leader (female) was kind to me and lent me a BB calling machine so that I could be notified at any time to go to work. Within a few months, due to the poor business in the workshop, I still had a group of classmates assigned to another SMT workshop. An episode made me almost surpassing the SMT industry! At that time, I was assigned to SMT together with another classmate. -Line 4 (remember that there is an SMT template frame behind the machine), I was sent to the warehouse preparation area! It seemed that I was going to be a material clerk. Later, an SMT supervisor saw that I was thinner than my classmate (My weight at that time: 120 kg, and now I am far overweight!), I felt it was suitable for learning SMT equipment and I entered SMT industry.
Later, the SMT supervisor promoted me again, and said to him here: Thank you! (Sometimes people need to meet your noble person!) At first, I had a master who taught me (FUJI, Universal Equipment), I seem to be stupid and belong to the kind of slower progress. The line I have online is long It's a man, who pushes me every day, making my life very sad! Haha, I later asked a few classmates to take advantage of him to come back online at night, beat him up, and then invited him to a meal. I spent more than a year in the production line without knowing it. (It's cool to think about beating people!) As soon as the SARS period came in 2003, I paid attention to how many people died and whether there were any cases of infection in this city! At that time, we had to take our body temperature at work. A colleague jogged at work. Once the temperature was exceeded, he took 10 days of paid vacation! (That was really a special period) Someone in the workshop was wearing a mask! At that time, I remembered a slogan: unite together to fight SARS! I was promoted to a technician in May 2003 and I was very excited for a day! (It was still promoted by the SMT supervisor in front) But it didn't take long to find out that it was SMT equipment maintenance, not with wires, and I was a bit lost! It is also the equipment maintenance experience that makes me engage in equipment maintenance or equipment management in the future, and have more feelings and awareness than others! During that period of equipment maintenance, we had maintenance plans almost every day, and we were very tired! Since then, I have gradually read various equipment materials, such as DEK265: I go home at night to check circuit diagrams, adjust the equipment (fortunately, my major is electronics, and I have learned well), and I use idle equipment during the day to compare related circuits and Parts, just like that I am lurking and learning! At this time, I am already the leader of the maintenance team, taking advantage of all equipment maintenance opportunities (including manufacturer maintenance) to learn! Generally, no one wants to spend time on repairing edge equipment such as SMT track and plate washer in our place, but I am very enthusiastic about repairing. These experiences made my equipment maintenance ability very extensive and not limited to a certain type of equipment. My ability has reached the level of workshop SMT equipment engineering! (Similar to how to master equipment maintenance as soon as possible, I had a lesson before).
At the beginning of 2005, I was promoted to be an SMT engineer in charge of repairing the equipment in the workshop (more than 3 years since I joined the company!). I attach great importance to every failure of the equipment, even if someone else fixes it, I will research it thoroughly. Since then, my equipment capabilities have become more and more proficient and more accessible, and I am having a very happy life! (Actually, the upper-level struggle is very fierce, I only pay attention to my equipment!) It was also this year that I got married and bought a house, and I was under great pressure! ! ! On April 10, 2006, I left my first company. Very reluctant, in fact, I really miss it! On the last day of the trip, I took a picture of my usual toolbox (hex wrench, multimeter, gauge, etc.) and took a picture (I have a chance to upload!), and bid farewell to my colleagues one by one! My second company is an SMT equipment agent (well-known in the industry), which fulfills my two goals: 1. To be an equipment maintenance agent and to walk the world with tools; 2. Get married and live under pressure. The salary has gone up!
It didn’t take long for me to work as an agent, and I discovered that repairing equipment is not my pursuit! (Many things look beautiful, but not after you get in touch with them) Leave the equipment agent to consider:
1. I have been a senior equipment maintenance engineer for more than 5 years, just like that, I will be a certain kind of machine; 2. In the future, the agent status will be lower and lower, and special maintenance equipment will not be as popular as in the early days; 3. For manufacturers in the future, agents are not whether they can repair the equipment, but the key is whether they can bring added value to the factory---for example: equipment capacity optimization experience; equipment efficient management; equipment asset operation, etc.! In addition, I just had a child at that time, and it was inconvenient to travel frequently! (If I am now, I guess I would have to go on a business trip to work! Haha!) I have been working in an agent for nearly a year, I have learned a lot from it and I have a more comprehensive understanding of the equipment! I also got acquainted with many industry experts!
Thank you for that time, thank you for that experience! At the beginning of 2007, I joined a European SMT company responsible for SMT equipment. I learned a lot about equipment, craftsmanship, handling and handling of things there! In fact, there are more mixed ones than mine, my colleagues and friends! Maybe in the last 5 years, there has been little momentum, little development, and we have stayed in place! Perhaps compared to the old dicks at the same time, I have not put down my tools on the front line, repaired, maintained, adjusted, analyzed and solved process problems by myself, and the combat effectiveness has been maintained, perhaps only for the emotion of SMT! (A bit silly Come on!!!) Let’s talk about the European company that I entered at the end of 2006 (10/7). I just joined as an equipment engineer. (Thanks to the factory manager who recruited me!) It is a small-scale enterprise, and the total line body is about 5 lines. I really wanted to leave after I went there for about a month, and I felt like I was in the wrong job! (Unexpectedly, it will last for 6 years)
the reason: 1. The whole factory does not seem to have much planning, and the production site is rather messy; 2. The equipment is quite old; 3. I just went there and nobody paid any attention to me, and I felt very depressed; 4. It turns out that technicians and assistant engineers don't want me to come, you know! It caused me a lot of trouble, think about how a person from an agent can be so angry! (At that time, I was stupid and couldn't see some things clearly) I was suffering from the two-month trial period, but the annual prize was not given to me and I was not rated.
I had a firm belief at the time: if I can't handle these people, how can I have confidence in these devices in the future! The technician made trouble for me (the technician and I are not managed by the same boss!), and reported a small problem. I was a big fan at the time. I believe in my technical strength. If there is a problem, the key is that the equipment has been maintained for at least one year. Like CP6-holder, the card is very dead, so it is proposed to carry out maintenance immediately. Otherwise, these soft faults cause downtime and loss every day. It was originally well maintained, but it went to the factory manager! (Really funny!) The technician insists that there is no way to disassemble the holder without a special fixture. My insistence is that the situation is urgent now and the production task is tight. The equipment must be maintained and adjusted as soon as possible, rather than delayed. I said that there is a way to clean the holder without disassembling it, and the technician still insists stubbornly that this will damage the parts and so on! In the end, I said yes, stand beside me and see if I have taken care of it! In this way, I gradually did basic maintenance of the SMT equipment, and I gradually became familiar with the condition of the equipment here, and gradually the soft failures of similar equipment were reduced! In fact, the first half of my visit was not good, and the boss didn’t think of me very well! I have gradually gained the recognition and trust of upper-level managers just by taking things seriously and studying regardless of specialization. (A lot of things require time running and your persistence!)
After experiencing the heavy snow in early 2007 (does anyone remember?) I took a lot of snow scene photos with my newborn son and wife in our hometown. Thinking about time is really a killer. (My son will report to the first grade in a few days. I hope that he can overcome himself in the future and keep moving forward! Learning smoothly!) In May 2007, the technicians who sang against me were gone. . I also recruited technicians again, so I'm naturally obedient! I gradually entered the role and started to manage the daily production, equipment, and process of SMT. At the end of the year, I was promoted to equipment supervisor. I would like to thank my manager for giving me trust and growth! A lot of things also happened in 2007, such as: new equipment purchases, replacement storms, etc.! ------Sometimes you have to stick to it! This is a question of professionalism! In an instant, the freezing disaster in early 2008, no one has forgotten it! (It takes me 3 hours to commute to and from get off work every day, so the road is not easy!)
Remember the photos of the armed police soldiers at Guangzhou Railway Station? It’s touching! I heard about the Sichuan earthquake in the factory on May 12, 2008, and I thought it was nothing! As soon as I turned on the TV when I went home, I was anxious. I don’t know the situation of Beichuan, Beichuan and Beichuan? At that time, I felt that the hearts of the people of the whole country had reached Sichuan, Beichuan, and Yingxiu Town! The most talked about topic at work is the Wenchuan earthquake! It was also during that time that the Olympic flame was robbed in Europe. The overseas post-80s have come forward. Who said that the post-80s are Jiaodi’s only-child generation. As a post-80s generation, I am determined to stand up for it! Nowadays, many of us have entered a new year, life is confused, and pressure makes our generation feel that we can't be charming! The Olympics kicked off on August 8, 2008. I remember that I had an appointment with my classmates at the school. See you at the opening of the Olympics in Beijing. Haha! The opening ceremony was too dreamy, unparalleled and no exaggeration! It seems that we are hosting the Olympics more glamorously than the London Olympics. In September 2008, the foreigner boss bought some FUJI equipment from abroad. About a month later, Lehman in the United States went bankrupt! The US subprime mortgage crisis has come, and it seems that the global economy is still in a downturn.
Our company went on to lay off people, so naturally I am not among them (I am already the main player). The production line is basically laid off at a rate of 50%, and my SMT operators have basically been laid off! (For the subsequent year-long production turmoil planted hidden dangers) By April 2009, our production gradually increased, but the people are gone, the key is that many skilled and old employees including technicians are missing. During this period, recruitment, training, resignation, and re-recruitment fell into such a vicious circle. I had to work overtime until 8 o'clock every day. At that time, equipment was no longer my focus, but people, people, and people! In this way, we continue to evaporate. Under the manager's plan, we gradually established a training mechanism and a skill assessment mechanism. Problems such as declining output, poor quality, and inability to recruit personnel broke out this year, and it was this year of training that made me more comprehensive in SMT, and I became more calm and confident in dealing with difficulties in future work! Everything has basically stabilized in 2010, and I gradually turned to the craft field. In fact, I have been doing it before, but I have spent a lot of time in it since 2010. Looking at materials science and engineering mechanics, these basic process theories require knowledge, including various professional journals in the industry, foreign technology frontiers, process paper analysis papers, failure analysis, etc. Participating in special lectures held by various experts, encountering process problems in combination with my actual work, and being familiar with IPC related technical specifications and recommendations, gradually I have a considerable ability to analyze problems independently! Until now, I am still fighting on the front line of SMT, but I have a more comprehensive understanding and views on SMT!
In the blink of an eye, it is only ten years. The development of SMT in mainland China has gradually changed from a high-tech, high-input, high-paying industry to a mature technology, low threshold input, and no competitive salary! Whether SMT new dicks or old dicks like me, everyone is thinking about their future. In fact, no matter whether you will continue to work in the SMT industry in the future (I saw many people have fled!), as long as we are still in this industry, we must have a perseverance mentality and we will gain!
Four special electroplating methods for circuit board electroplating
It is often necessary to plate rare metals on board edge connectors, board edge protruding contacts or gold fingers to provide lower contact resistance and higher wear resistance. This technique is called finger row plating or protruding part plating. Gold is often plated on the protruding contacts of the board edge connector with the inner plating layer of nickel. The gold fingers or the protruding parts of the board edge are manually or automatically plated. At present, the gold plating on the contact plug or gold finger has been plated or lead , Instead of plated buttons. The process is as follows:
1) Strip the coating to remove the tin or tin-lead coating on the protruding contacts
2) Rinse with washing water
3) Scrubbing with abrasives
4) Activation is diffused in 10% sulfuric acid
5) The thickness of nickel plating on the protruding contacts is 4 -5μm
6) Clean and demineralize water
7) Gold penetration solution treatment
8) Gold plated
9) Cleaning
10) Drying
The second type, through-hole plating
There are many ways to build a layer of electroplating layer that meets the requirements on the hole wall of the substrate drilled hole. This is called hole wall activation in industrial applications. The commercial production process of its printed circuit requires multiple intermediate storage tanks. The tank has its own control and maintenance requirements. Through-hole plating is a necessary follow-up process of the drilling process. When the drill bit drills through the copper foil and the substrate underneath, the heat generated melts the insulating synthetic resin that constitutes most of the substrate matrix, the molten resin and other drilling debris It is accumulated around the hole and coated on the newly exposed hole wall in the copper foil. In fact, this is harmful to the subsequent electroplating surface. The molten resin will also leave a layer of hot shaft on the hole wall of the substrate, which exhibits poor adhesion to most activators. This requires the development of a class of similar stain removal and etch back chemical technology.
A more suitable method for prototyping printed circuit boards is to use a specially designed low-viscosity ink to form a highly adhesive and highly conductive film on the inner wall of each through hole. In this way, there is no need to use multiple chemical treatment processes, only one application step, followed by thermal curing, can form a continuous film on the inside of all the hole walls, which can be directly electroplated without further treatment. This ink is a resin-based substance that has strong adhesion and can be easily adhered to the walls of most thermally polished holes, thus eliminating the step of etchback.
The third type, reel linkage type selective plating
The pins and pins of electronic components, such as connectors, integrated circuits, transistors, and flexible printed circuits, all use selective plating to obtain good contact resistance and corrosion resistance. This electroplating method can be manual or automatic. It is very expensive to selectively plate each pin individually, so batch welding must be used. Usually, the two ends of the metal foil that is rolled to the required thickness are punched, cleaned by chemical or mechanical methods, and then selectively used like nickel, gold, silver, rhodium, button or tin-nickel alloy, copper-nickel alloy , Nickel-lead alloy, etc. for continuous electroplating. In the electroplating method of selective plating, first coat a layer of resist film on the part of the metal copper foil board that does not need to be electroplated, and electroplating only on the selected copper foil part.
The fourth type, brush plating
Another method of selective plating is called "brush plating". It is an electrodeposition technique, and not all parts are immersed in the electrolyte during the electroplating process. In this kind of electroplating technology, only a limited area is electroplated, and there is no effect on the rest. Usually, rare metals are plated on selected parts of the printed circuit board, such as areas such as edge connectors. Brush plating is used more when repairing discarded circuit boards in electronic assembly shops. Wrap a special anode (a chemically inactive anode, such as graphite) in an absorbent material (cotton swab), and use it to bring the electroplating solution to the place where electroplating is needed.
PCB manufacturing and assembly of permanent magnet rotary vibrating pelvic inflammation treatment instrument
Scope of application: Pelvic inflammatory disease and infertility caused by obstructive fallopian tube. 1. Inflammatory tubal obstruction and infertility: any part of the fallopian tube is blocked, blocked, unobstructed, fluid in the tube cavity, and the umbrella end is raised. 2. Chronic pelvic inflammatory disease: pelvic peritonitis, metritis, adnexitis (oophoritis, salpingitis), surrounding connective tissue and ligamentitis. Applicable departments: Reproductive center, infertility department, gynecology department. According to industry data, it can be seen that the clinical incidence of female pelvic inflammatory disease is high, and the age of onset is large (from 15 to 55 years old). It is a common disease that seriously affects women's health. If the condition is repeated and troubled for a long time, it can cause neurosis; if inflammation involves the fallopian tube, it can cause the fallopian tube to be blocked or blocked, leading to ectopic pregnancy or infertility. Infertility due to obstructive fallopian tube is the main cause of female infertility, and the incidence continues to increase. Statistics in recent years have shown that: tubal obstructive infertility has accounted for about 50% of female infertility. The device perfectly combines oscillating magnetic field, rotating magnetic field, magnetic vibration wave, mechanical wave, and low-frequency sound wave, and the physical effects produced by them can reach deep organs and tissues of the pelvis. At the same time, the mechanical vibration of a specific frequency and its synergy can help loosen the adhesion of deep tissues and organs of the pelvic cavity. It has the clinical effects of reducing swelling, relieving pain, promoting the absorption of inflammatory secretions, eliminating inflammation and adhesion, and restoring the patency and function of the fallopian tube. The permanent magnet rotary vibration treatment device is a comprehensive gynecological treatment device that combines a pelvic inflammation treatment device and a fallopian tube blockage treatment device. FASTPCBA specializes in undertaking medical electronic PCBA proofing and PCB assembly batches and other related businesses. It mainly focuses on high-end SMT placement and proofing. It has 5 fully automatic placement processing production lines that can achieve the smallest size of 01005 component placement; reflow oven adopts For the nitrogen furnace with twelve temperature zones, the company has an independent nitrogen generator, which provides strong support for the realization of vacuum welding and oxidation resistance.
From the previous handicraft industry to the current advanced power, under the global COVID-19, technology has been encouraging China's advanced development.
In today's in-depth development of globalization, countries are closely linked and interdependent. No country can stay out of the epidemic, and no country can respond to the epidemic alone.
When inspecting the progress of the research work on epidemic prevention and control research at the Military Medical Research Institute and Tsinghua University School of Medicine, President Xi Jinping pointed out: The most powerful weapon for humans to fight against diseases is science and technology. .
So now the most scarce resource is medical equipment. Advanced medical equipment is a powerful weapon for human beings to overcome various diseases, setting an example for global scientific research cooperation. In the face of the new coronary pneumonia epidemic that is ravaging the world, China attaches great importance to international scientific research cooperation in epidemic prevention and control, as does FASTPCBA, in order to build semiconductor production for "prevention and control of new coronary pneumonia research." Several new equipment were introduced from yesterday to speed up production. I hope to give China a trivial force.
In the face of the rampant epidemic, Chinese technology has never stopped to cheer for the motherland. Many researchers have been struggling on the front line of scientific and technological innovation: the application of 5G technology in many fields, the launch of spacecraft with more than 20,000 kilograms for the first time in China and even Asia, the first 3D printing of space in China, the release of the world ’s first new crown vaccine animal experimental research results Sub-sampling robots ... Science and technology are prosperous for the nation, while science and technology are strong for the country. FASTPCBA wishes that the flower of Chinese science and technology will become more and more splendid, and the light of struggle will shine through the stars.
