Due to cost considerations, many factories are gradually entrusting the soldering of electronic components to professional technical factories. Among them, SMT is currently the most mainstream soldering technology. 2, What is SMT?SMT (Surface Mount Technology), also known as surface mounting technology, refers to a technology that installs electronic components such as resistors, capacitors, transistors, and volume circuits onto the surface of a circuit board (PCB). Surface soldering is mainly done by printing Solder Paste on the circuit board to be soldered, placing electronic components, melting the paste at high temperature, allowing the paste to coat the electronic components, and when the temperature cools and solidifies, surface soldering is completed. 3, What are the differences between SMT, SMD, SMA and SME?These three words are all closely related to SMT. In simple terms, SMT is a soldering technology, SMD and SMA are electronic components to be soldered, and SME is the soldering machine. Abbreviation, full name, Chinese explanationSMT Surface Mount Technology is the technology of installing electronic components on the surface of a circuit boardSMD Surface Mount Device (SMT) is a single electronic component installed on the surface of a circuit board, such as resistors, capacitors, and integrated circuitsSMA Surface Mount Assembly (SMT) is an electronic component installed on the surface of a circuit board, and this component contains one or more combinations of electronic components, such as Bluetooth modules and WIFI modulesSME Surface Mount Equipment is a machine that installs SMDS on the surface of circuit boards 4, SMT production processTo successfully install electronic components on a circuit board through SMT, mainly three processes need to be gone through: Process description: Use the equipmentSolder paste printingPrint solder paste at the positions on the PCB where electronic components need to be installed with a solder paste printer2. Make a patchPlace electronic components at the positions where solder paste is printed on the PCB with a component placement machine3. Re-welding heatingThrough the reflow oven heating, the solder paste on the PCB is melted to connect and fix the electronic components to the PCB in the reflow oven 5, Advantages of SMT TechnologyThe biggest difference between SMT and the previous through-hole mounting technology is that SMT does not require reserving through-holes for the pins of electronic components, thus allowing for the use of smaller electronic components. There are mainly the following three advantages for electronic products to adopt SMT technology: 1. Thinner and lighter in size:By using smaller electronic components, the required circuit board area will also decrease, and the volume of electronic products can become lighter. 2. More high-end products:When electronic components become smaller and thinner, electronic products can be applied to more diverse fields, such as micro-robots, cpus, portable electronic products, etc., and more precise and high-end products can be designed. 3. Easier mass production:SMT uses machinery and equipment to complete surface soldering. Compared with the manual insertion operation in the past, it is more suitable for mass production, and the manufacturing process is also more stable than through-hole insertion. 6, Introduction to SMT Equipment Dispensing machine SMT equipment recommendation - The dispensing machine is used to precisely dot, inject, apply and drip liquid to the correct position of the product. It can be used for dotting, drawing lines, circular or arc-shaped shapes. This model is patented for the Automatic Process Calibration Injection Technology (CPJ), which can automatically compensate for the viscosity of the colloid to maintain a fixed amount of glue. It will also automatically measure the weight of each glue point and adjust the pressure to maintain the consistency of the glue amount for each component Fully automatic solder paste printing machineSMT Equipment Introduction - The fully automatic solder paste printer is a fully automatic model. After setting the relevant parameters, it can automatically feed in the board, align, print solder paste, and discharge the board. It can automatically optically correct the printing position. The printing accuracy is ±12.5. The two-stage waiting mode can reduce the machine's transportation time. It supports multiple printing demolding modes and can select the best printing conditions for different parts. Nitrogen reflow soldering furnaceProfessional SMT equipment - nitrogen reflow ovenUniformly heated gas is provided to melt the solder paste, allowing electronic components to be connected to the circuit board. Compared with the common reflow oven, the nitrogen reflow oven can effectively reduce the bubbles at the solder joints and avoid thermal damage to power devices at a high-quality level. Chip placement machineSMT equipment application - A surface mount technology (SMT) placement machine is a device that accurately places electronic components on a PCB by moving the placement head. It can identify various types of component patterns and place components at high speed and high precision. It is divided into two sections, with each section consisting of two tables for CHIP processing. Each Table is equipped with 12 suction nozzles, capable of simultaneously processing 12 CHIP components. Selective wave solderingSMT product equipment - Selective wave soldering is used in through-hole mounting processes. By taking advantage of the easy movement of small nozzles, the PCB is fixed on the rack, and the nozzles are moved to bring the solder solution into contact with the solder pins of electronic components. The tin pot and tin pump system can move freely in the X/Y/Z axis directions, and the entire process can precisely control the tin eating position through the program. Welding selection machineHigh-quality SMT equipment - adjustable PCB positioning frame of the soldering machine, two tin POTS with independent Z-axis control, increase the flexibility of soldering, and two nozzles of different sizes can be used according to different solder joints. Automatic soldering machineThe automated SMT equipment - the automatic soldering machine is an automated soldering device that can significantly save the time for replacing fixtures. During the soldering process, it can simultaneously position the products to be soldered. It is equipped with a soldering iron thermometer to measure the temperature and make corrections based on the actual temperature. It is also equipped with a built-in temperature check system. If the temperature is abnormal, it cannot act. Automatic pneumatic nozzles and roller brushes can also be used to clean the soldering iron tip. Selective coating/dispensing systemTaiwan SMT equipment - Selective coating/dispensing system is used to precisely spray liquids and colloids onto the correct positions of products, providing a stable amount of adhesive for a wide range of PCBS, BGA, etc. The mechanical drive mechanism with XYZ repeatability accuracy of 25 microns can flexibly perform conformal coating and dispensing.

Preheating module system       After the PCB board is sprayed with flux, it will reach the preheating zone to heat and activate the flux. The preheating module is mainly equipped with the top hot air and the bottom infrared heater, and the power heating mode is also configured for the PTH complex process PCB. To ensure efficient, safe and uniform heating.   Welding module system     After entering the welding zone from the preheating zone, the machine will position the pcb and start welding. The welding module is driven by electromagnetic pump. It can be configured with double tin cylinder to meet the production demand. At the same time, it has nitrogen protection to ensure durable and reliable welding.   Tin bead cleaning module system     After the welding is completed, the cleaning module will clean the residual tin beads on the welding plate.

"During the Spring Festival alone, nearly 100 investment institutions asked people to introduce them to see if there was an opportunity to invest in DeepSeek." In the face of the phenomenon of DeepSeek, a large model released by domestic AI companies, an angel investor admitted to the Surging news reporter, "We need to think about why projects like DeepSeek were previously missed by us." DeepSeek technology boom triggered a global shock, the stock prices of many technology giants on the other side of the ocean plunged, and artificial intelligence leader Nvidia fell 4.3 trillion yuan in market value overnight. "DeepSeek does not have a promotional budget, nor does it have an annual salary of 10 million people, it is a clear goal to invest in research and launch products." The above investor comments. Another large model unicorn told reporters that "DeepSeek founder Liang Wenfeng is a person with AI beliefs, and the technical romanticism he insists on is very well-known in the industry." "Don't miss the next DeepSeek because you follow DeepSeek, what we need is not a rush to pursue and imitate, the era of artificial intelligence will force humans to return to the source of value." Fudan University School of Computer Science and technology professor, Shanghai Key Laboratory of data science director Xiao Yanghua told reporters. In his view, behind the rise of DeepSeek is the epitome of China's AI power, and a group of artificial intelligence startups similar to DeepSeek are standing on the world stage. Why DeepSeek broke through "DeepSeek was out of my reach last year. Now it's out of my reach." Tao Ru, an algorithm engineer at an AI company in Shanghai, told Surging news reporters with a smile that as an algorithm graduate of a top domestic university, he had received an olive branch from DeepSeek last year, but finally gave up because he was worried that the company was not well-known enough and would not focus on AI. On social media, many fresh graduates have shown DeepSeek's job invitation, and the words are quite regrettable. Also "missing" DeepSeek there is a circle of investment institutions, "DeepSeek company executives are clearly not interested in commercialization, just want to do technical research." Investment institutions need to commercialize the company, have revenue profit and capitalization requirements for the company, and also need the founder to surrender a certain degree of equity and freedom." An investor admitted that, in fact, no practitioner of AI investment does not know DeepSeek, and some people extended an olive branch before the explosion. But the end result is that no VC (venture capital firm) has successfully invested in the company. Some people who know DeepSeek told reporters that they had interviewed some talents in the field of AI, and finally rejected their own company and went to DeepSeek, on the grounds that they had a good scientific research atmosphere and were a team that really did things. "In terms of salary package, DeepSeek is only in the middle of the industry, not the highest." He admitted, "The density of talent may not be as good as the head of the big factory, not that the people in the big factory are not smart, but the smart people in the big factory spend too much energy outside of technology." "Big companies pay well, but their internal struggles are fierce, and the desire to focus on technology is not as pure as a technology company like DeepSeek." "DeepSeek's popularity was due to chance, but more to necessity." Xiao Yanghua told reporters. "The parent company behind it, Magic Capital, has strong technical strength and computing power foundation in the field of quantitative trading and intelligent finance. At the end of 2022, when OpenAI just launched ChatGPT, there were few domestic clusters of Wanka, except magic Square. In addition, the convergence of a large number of AI-related talents in the financial field also gives DeepSeek a deep talent advantage." "It's more about the change in mindset." Xiao Yanghua admitted that most AI companies in the past were eager to achieve success, busy with brush list, publicity, realization and capital accounting, while DeepSeek was calm and focused on technical exploration, allowing the team to drive research and development based on curiosity, and was not eager to commercial realization. In terms of environmental factors, Hangzhou, where DeepSeek is located, has an advanced innovation environment. The government has created an atmosphere of tolerance, trial and error and exploration, and only built platforms without interfering with the innovation direction of enterprises, which is very conducive to the development of enterprises. Tan Jian, associate professor of intelligent interaction design at Beijing University of Posts and Telecommunications, believes that the key changes brought by DeepSeek mean that, as the cost of the model decreases, in the future, high-level AI applications will be promoted by small and medium-sized enterprises, and form a "hundred flowers" situation, and in the short and medium term, cloud computing, edge computing, and server three types of manufacturers. "At present, the three major operators and many Internet computing service platforms have connected to DeepSeek and provided Internet access, and it can be predicted that the revenue of these traditional cloud services and computing platforms will rise steadily as the entire population registers AI services." DeepSeek is not the only Chinese DeepSeek's explosion also lets the outside world see that China has formed a number of powerful and influential companies in the large model industry, including ByteDance, Ali, Tencent and other large factories, and there are start-ups such as Moon's dark side, Wisdom spectrum and MiniMax. On the first day of the New Year after DeepSeek hit the whole network, Ali Yuntongyi team released its flagship model "Qwen2.5-Max", becoming the second Chinese large language model that can match the o1 series of OpenAI company in the United States, which once again caused a shock. According to the ranking of the third-party platform, "Qwen2.5-Max" ranked 7th in the overall list with 1332 points, surpassing the deep search "DeepSeek-V3" and OpenAI's "o1-mini". In math and programming, "Qwen2.5-Max" ranked first and second in Hard prompts. The AI unicorn "Dark Side of the Moon" was established in April 2023, and its legal representative Yang Zhilin graduated from Tsinghua University. He earned a doctorate from Carnegie Mellon University in the United States and started his own business in Beijing. According to third-party data, as of January, the company valuation on the dark side of the month has reached $3.3 billion. MiniMax, a Shanghai-based AI unicorn, was founded in December 2021 with large multi-modal models of text, voice, music, images and video. A highlight worth noting is that MiniMax is at the forefront of the country in terms of AI going to sea. The latest data show that MiniMax's Conch AI overseas version topped the global AI video list in December last year, with more than 27 million monthly visits. Liu Hua previously told surging news reporters that the United States is in a leading position in AI large model technology as a whole, and in voice, video and other segments, China's large model catch-up speed is fast, such as conch AI and Kuaishou's large model are widely used in the United States, and at present in these fields, the technical level of the two countries has reached a stage of equal. "In fact, the rate of iteration and evolution of large model technologies in the United States today is actually slower than before." Liu Hua said, "At present, the leading enterprises in the United States have or are building 100,000 card clusters. There are even plans to build million-card clusters to train more advanced models. However, the realization of the million-card cluster faces many challenges, among which whether the local large-scale power facilities support is one of the key factors." Against this backdrop, Chinese companies are rapidly catching up with their American rivals. DeepSeek is like a "catfish", once again stimulating the vitality of AI competition. "The large model field has not yet formed an absolute moat, the industry is still in the early stage of development, and there is still a long way to go from the mature stage." Chen Cheng, a veteran observer of the AI industry, told Surging news reporters that he guessed that competition and internal volume in the large model industry would be further intensified after DeepSeek exploded. "The fierce competition between manufacturers, the most benefit is undoubtedly the user of the large model, that is, the ordinary user, they will enjoy the continuous evolution of the large model capability, the continuous improvement of the cost of the dividend." A well-known AI company told reporters that DeepSeek is not perfect, v3 model mainly in mathematics and code and other capabilities are more prominent, other general class text generation, understanding and other effects have room to improve, on its particularly low training costs, does not include all costs. (Editor's note: v3's published training cost is about $5.576 million. A third party report points out that the $5.576 million figure mainly refers to the cost of the GPU for model pre-training, and does not include other important costs such as R&D, data collection, and cleaning.) "After the explosion of DeepSeek, it will undoubtedly stimulate all parties in the industry to further invest in benign technology competition, which is extremely beneficial to the development of the entire industry." At present, in the large model circuit, companies are working hard to achieve better performance, and this dynamic competitive atmosphere is very rare." Another AI startup insider admitted to reporters that "at this stage, who will fall behind and who can stand out are still unknown." In order to survive and develop in the competition, we will definitely invest more resources, and the whole industry is full of vitality and development potential." How does the DeepSeek effect work Hu Yanping, chief expert of FutureLabs FutureLab, said that DeepSeek has become an effect, including four aspects, namely, the cost effect of computing power, the user detonating effect, the confidence boosting effect and the open source ecological effect: "Next, there will be a new phenomenon, many slightly strong related enterprises will be based on the base of the large model to do a variety of post-training, distillation fine-tuning, combined with knowledge base, etc., and then to face thousands of industries, forming a large model industry in the AI 2.0 era of the back of the market." Based on this observation, Hu Yanping believes that the AI industry has three potential directions next: the first direction is the end of the first cycle of AI 2.0 represented by the large language model, and the second cycle represented by multi-modal, embodied intelligence, space-time intelligence, etc.; The second direction is the aftermarket of AI large models, that is, the ecological emergence of the waist and long tail; The third direction is end-to-end AI agents, especially those that can be integrated with workflows and individual needs. In Xiao Yanghua's view, many AI startups have a good university background, and there is no shortage of talent and funds, but there is a general problem of mental anxiety, too eager, but not conducive to original innovation. "Companies need a more relaxed development atmosphere and develop steadily according to their own pace and strategic direction." He believes that, in fact, governments around the world are now very concerned about AI companies, but the lack of truly excellent, take out of hand enterprises, "the government's concern should be moderate, after building a good environment and platform, there will be no more intervention." "Caring too much can disrupt the pace of business. It's more important to be a smart carer." In addition, the emergence of DeepSeek, proved that AI enterprises rely on burning money volume "investment flow" "customer" path is not feasible, the past Chinese AI large model "volume" computing power, "volume" price, "volume" customer, "volume" liquidity ability, now people more recognize the original innovation of long-term, enterprises should think about structural innovation and low-cost research and development, Instead of burning money. "Big AI models are a very risky investment track with huge amounts of money, and only a few companies will survive, which means that many investments in companies will fail." The vice president of a large model enterprise told the Surging news reporter that in the current environment, the US dollar fund cannot achieve the traditional "investment and financial tube withdrawal" path because of the reason of fund-raising limitation, "the large model industry must accept a reality, and the government will guide the foundation to play a more important role." From a formal point of view, he suggested that you can refer to the current domestic and international computing power coupons. For example, now the state-owned enterprises can establish a computing power cluster to provide computing power for large model enterprises, and after the investment, most of the investment funds will be returned to the hands of state-owned enterprises in the form of computing power leasing fees. Xiao Yanghua believes that the wave of entrepreneurship set off by the large model industry means that private enterprises and small and micro enterprises play an important role in the national science and technology innovation system, and will drive more enterprises to flourish in the future. "Enterprises are often the most curious and creative in the start-up and small and micro stage. Curiosity is like a precious spark. It is so precious that the whole society should take good care of it so that the seeds of innovation can continue to take root and grow in the right soil."
