RF Passion, Craftsman’s Journey: Over 30 Years of Steadfast Dedication — Interview with Kinghelm Chief Engineer Mr. Qin hongxiang
Kinghelm Chief Engineer Mr. Qin hongxiang Kinghelm Chief Engineer Mr. Qin hongxiang emphasized: "Kinghelm’s flagship products are RF microwave antennas, signal connectors, and related components. The company is also involved in three major communication technologies: RF microwave, high-speed data transmission, and optical communication. Our product strategy follows the development trends of the times and national planning. For example, satellite communication and optical communication components (optical devices) are markets with enormous demand. China is simultaneously advancing three major mega-constellation satellite programs — the GW constellation with 13,000 satellites, the ‘Qianfan’ constellation with 15,000 satellites, and the ‘Honghu-3’ constellation with 10,000 satellites, with a total scale exceeding 40,000 satellites. This will unlock trillions of yuan in market demand." Notably, in August 2025, the Guiding Opinions on Optimizing Business Access to Promote the Development of the Satellite Communication Industry was released, setting a target of over 10 million satellite communication users and large-scale direct-to-cell satellite applications by 2030. In June 2026, the Implementation Opinions on the Innovative Development of "Artificial Intelligence + Information and Communication" (2026–2028) was issued, designating satellite internet as a core breakthrough track for the next three years. It explicitly calls for deep integration of satellite communication, 5G/6G, artificial intelligence, and other next-generation information and communication technologies. Satellite communication, as the "space version" of microwave communication, represents one of the largest application scenarios for RF microwave technology. 6G, the sixth-generation mobile communication technology, aims for an ultimate "space-air-ground integrated" form — where satellite communication solves coverage, optical communication solves capacity, and AI handles scheduling. Artificial intelligence (AI) is driving the construction of high-speed optical communication networks and bringing disruptive changes to every industry. "AI + High-Speed Mobile Connectivity" is set to become the mainstream landscape of future society. Kinghelm started by developing and producing "Kinghelm" brand Beidou (BDS)/GPS antennas and has long focused on RF microwave technology. These strengths position the company well to seize new opportunities. Ⅰ. Learning Comes First Mr. Qin during an exclusive interview with the Kinghelm reporter team In this issue, the Kinghelm reporter team interviewed Chief Engineer Mr. Qin. Born in the 1970s in Chengdu, Sichuan, he graduated from the University of Electronic Science and Technology of China (UESTC) in Chengdu. Describing the renowned vibrant atmosphere of Chengdu and the Sichuan-Chongqing region, he said: "The cultural character of Chengdu and the broader Sichuan-Chongqing area is one of comfort, ease, and unhurriedness. People here strike an excellent balance between work and life. They devote themselves fully during the five workdays with high intensity and pressure, but after intense work, they need relaxation and rejuvenation. Chengdu’s living environment is excellent — people enjoy nightlife on weekdays and engage in outdoor activities, vacations, farm stays, card games, fishing, cycling, hiking, rural leisure trips, and parent-child activities on weekends. These are all normal ways to relieve stress." Only by loving life can one truly love learning. Mr. Qin stressed that among all things, learning ranks first. He graduated in 1992 from the prestigious 985 university UESTC and shared: "My father was also a graduate of a 985 university. From a young age, I saw how knowledge can change destiny. My parents always taught that knowledge is the core and foundation of all things." Indeed, without a solid knowledge base, one cannot see the true nature of things, analyze problems correctly, reach sound conclusions, or solve issues effectively. Mr. Qin deeply understands that in the face of a complex society, knowledge gives me inner conviction and confidence. Regarding learning first, he recalled a major life decision during his school years: whether to enter high school and pursue university or attend technical secondary school and start working early. His father had a long heart-to-heart talk with him. He chose decisively to enter high school and aim for university because he wanted to accumulate sufficient knowledge and continuously improve himself to better face the future. Work is the best form of learning. Mr. Qin has been deeply engaged in the RF microwave field for over 30 years, constantly advancing through learning, thinking, practice, and reflection. His career can be divided into three stages. From 1992 to 1999, his experience in a state-owned enterprise laid a solid technical foundation in microwave and RF. "My university major was radio technology. After graduation, I was assigned to Chengdu No. 630 Factory, where I worked on the R&D of receiver systems and TV transmitter systems." From 2000 to 2006, he specialized in microwave equipment for mobile communications. "In 1999, during the wave of state-owned enterprise layoffs, I moved to Shenzhen and joined Germany’s Kathrein Telecom, working on microwave equipment for mobile communications and leading the engineering technical team. Later, I went to Suzhou and joined Andrew Telecom, continuing to deepen my expertise in microwave equipment for mobile communications." From 2007 to the present, he returned to the Pearl River Delta to contribute his technology and experience. "Years of cutting-edge technical research gave me sharp insight. I recognized early on the extraordinary vitality and competitiveness of the Pearl River Delta. It is a hotbed of entrepreneurship and innovation. So I made a life decision to return. I successively joined listed companies such as Foxconn, Luxshare, and Comba, gaining practical experience in managing R&D systems, building RF antenna technology platforms, and establishing antenna business units. In August 2025, seeing the strong momentum of Kinghelm and SLKOR, along with the vision and ambition of founder Mr. Song Shiqiang, I chose to join Kinghelm Electronics as Chief Engineer and embarked on a new journey of work and learning." Ⅱ. At Kinghelm Chief Engineer Mr. Qin deeply engaged in his work Mr. Qin outlined his four main areas of focus.The first is providing strong technical support to the sales team by promptly answering technical questions from salespeople and responding to customers’ technical requirements.The second is future product planning, where he is currently leading the implementation of the Kinghelm Future Product Roadmap. The third is professional technical training for headquarters staff, which aligns with the product planning. The fourth is supply chain management, ensuring stable quality, efficient delivery, and comprehensive technical service for Kinghelm’s global network of tens of thousands of customers. 1.Training First Kinghelm Chief Engineer Mr. Qin (first from left) training brand agent New Oriental Electronics!

Regarding the Kinghelm Future Product Roadmap, Chief Engineer Mr. Qin shared key signals. The plan began implementation in early 2026, and all work is progressing in an orderly manner. In 2026, Kinghelm will establish an initial product layout, with gradually enriched navigation antenna categories and the introduction of optical communication components. Kinghelm will formally enter the optical communication field. Although the technical barrier is high and brand building takes time, the company will first launch mainstream optical communication accessories and gradually rise from a latecomer to a leading player, helping the sales team open the market.On the implementation of this plan, he further stressed: "Looking back over the past thirty years, technological disruption has brought unprecedented changes. We must not rest on past achievements, become complacent, or allow our thinking to become rigid and closed. We must continuously drive technological innovation and product iteration." Ⅲ. Striving Upward, Embracing the Sun Chief Engineer Mr. Qin’s bright and airy office A good environment nurtures and transforms people, giving them strength and motivation. Chief Engineer Mr. Qin is proficient in English and Japanese. He said: "English and Japanese were my first and second hobbies in university. Working at the German company Kathrein gave me a natural English-speaking environment, while I learned Japanese purely out of interest. In my view, there are two keys to mastering a language: first, the right environment and atmosphere; second, passion as the driving force." He also loves experiencing nature and drawing energy from the heavens and earth. "I work out year-round and am passionate about outdoor cycling. I have a full set of professional mountain bike equipment. I often ride alone dozens of kilometers in forest parks, or cycle from Shenzhen to Zhuhai or Guangzhou and back — over 200 kilometers in a single day. I enjoy the process of cycling and love clearing my mind in nature." Lush plants in Chief Engineer Mr. Qin’s office nourish the spirit General Manager Mr. Song Shiqiang emphasized that since joining Kinghelm, Chief Engineer Mr. Qin has taken on responsibility and delivered results in technical support, headquarters staff training, future product planning, and supply chain management. He has helped elevate the team’s technical capabilities, advanced the company’s knowledge engineering, increased the knowledge density of both Kinghelm and SLKOR, and even promoted knowledge co-creation and sharing across the industry. When asked why he firmly chose to join Kinghelm, Mr. Qin replied candidly: "First, General Manager Song Shiqiang’s sincerity. During the interview, he shared the company’s plans, management methods, and philosophy, which aligned closely with my own thinking. He views the relationship between the company and employees not as a simple employment relationship but as one of mutual benefit, win-win cooperation, and joint pursuit of a better future. Second, employees feel respected and gain a sense of achievement. Mr. Song affirms that every employee who contributes sweat has the opportunity to share in the company’s future success. Third, the company’s care for employees. Kinghelm practices genuine humanistic care. When employees face difficulties, Mr. Song provides timely help and support — real assistance when it’s needed most." Kinghelm and SLKOR headquarters all-hands meeting, presided over by General Manager Song Shiqiang (first from right) Mr. Qin generously shared his over 30 years of work experience. In technology, one must be down-to-earth because technical accumulation is built step by step with no shortcuts. Product technical R&D must be done personally to gain first-hand experience. One must maintain an open mind and be good at accepting others’ opinions, as the biggest taboo in technology is rigid thinking and rejecting different views. Sharing and researching technology is a very joyful thing. The most important thing is to stay true to your heart, do the present well, and keep an eye on the world by following the latest technologies and societal trends to keep pace with the times. Maintain a positive mindset, do not impose your own knowledge and abilities on others, acknowledge your shortcomings, and have the courage to address them and strive to catch up and surpass. At the end of the interview, Chief Engineer Mr. Qin sincerely hoped that under General Manager Song Shiqiang’s leadership, the Kinghelm and SLKOR teams will unite, work together to improve, and drive development. He looks forward to both companies achieving brilliant success with a promising future, and for all employees to create extraordinary lives!

After Two Consecutive Titles, We Are Still making progress——Slkor Interview with Sun Gaofei
After winning the monthly sales team championship of the company's "A-team" for March and April, and with core member Luo Yanping winning individual sales champion twice, Sun Gaofei, Director of Sales Department I at Slkor, is leading his team to challenge for a third title. During the interview, he said, "The current state of our team is: going up the mountain to hunt tigers, and even the tigers are afraid of us." He then laughed, "But that's just an inside joke. Winning this championship is the result of everyone's hard work." Song Shiqiang, General Manager of Kinghelm & Slkor, presenting an award to Sales Department I Sun Gaofei majored in Applied Electronic Technology in college. After graduation, he worked in R&D for three years. His technical background has been a great help in leading the team – clients' technical staff are willing to have in-depth conversations with him, and he can directly help team members solve problems. However, when talking about the methods for winning the championship, he focused on team operations. His thinking is very clear: first break down the team's goals for each person, then have each person implement them with specific clients. In March, they proactively managed demand by having some clients place orders early. Entering April, he anticipated that this early consumption would lead to a slowdown, so he quickly adjusted the strategy – requiring the team to dig deeper into existing clients for other product models to generate incremental performance. "Since clients are already cooperating with us, their trust in us is very high." The effect of this deeper digging showed up in April, and the team fought another outstanding performance battle. Song Shiqiang, Luo Yanping, Sun Gaofei In his view, everyone's strategies are quite similar, and the most critical factor for success is the team's mindset. "One characteristic of our team is that whenever I say we need to push for performance, everyone is full of confidence and enthusiasm." The atmosphere where everyone is striving and trusts each other is the true competitive edge. After Luo Yanping won the individual sales champion for two consecutive months, Sun Gaofei specifically asked her to give a full-process sharing session – covering everything from client development, client follow-up, securing orders, to delivery schedule management, payment collection, and client maintenance. "Once a benchmark is set, everyone realizes this is not the ceiling, but the highest flag for now, and everyone wants to chase it." That sharing session received a good response within the team, especially for new members who were unclear about their goals; after listening, they knew in which direction to focus their efforts. Sales Department I champion trophy and mobile red flag The team's ability to charge ahead would not be possible without strong support from the back end. Sun Gaofei repeatedly mentioned the importance of the Slkor brand's reputation and cross-departmental cooperation: "The brand effect is very significant. Now the Slkor brand has gained recognition in the market, and the number of daily inquiries is stable. With timely cooperation from the supply chain, warehouse, and finance departments, we are able to close the deals. Performance is not just about the sales team fighting for orders; it is accomplished together by everyone." Sun Gaofei, Director of Sales Department I, during the interview Having served as Director of Sales Department I for over two years, Sun Gaofei believes the two most critical things in leading a team are: helping members solve problems and fairly distributing benefits. "As the team leader, you must solve problems satisfactorily, not just paint a rosy picture without taking action." He gave an example: while a team member was on maternity leave, her client in Zhongshan had a complaint. He immediately rushed there with an engineer and resolved the issue that same day. "Salespeople have sharp eyes; they know very well whether you can truly help them solve problems." Sun Gaofei's "Standardized Summary of Master-Apprentice Training" In terms of training newcomers, Sun Gaofei's first step is to "give a preventive shot". "In the semiconductor industry, no newcomer can achieve a breakthrough immediately after joining. Real growth comes from starting with small clients and moving to large ones, from following sample trials to mass production – this is a long process. But once you succeed, one good project can bring continuous returns for three to five years." In terms of specific coaching, he emphasizes eight words: "Be proactive, act with integrity." "Newcomers are confused when they join; we assign them mentors, but you must take the initiative to ask. The principle of our Sales Department I is that whenever a newcomer asks a question, we share everything we know." He says he has taught many people, but how much they learn depends on their aptitude. "The person who is proactive will definitely learn the fastest." Sun Gaofei training new salespeople on professional knowledge Slkor semiconductor product series Looking ahead to the semiconductor market in May, Sun Gaofei admitted that this time of year is usually peak season, but this year there is a slowdown, with even fewer clients asking for quotes. The team is currently adopting new strategies to maintain performance growth, but he is not comfortable disclosing them in advance. "It's not good to talk about things that haven't materialized yet." As for whether they can win the championship for the third time, his answer was very straightforward: "Stay tuned." General Manager Song Shiqiang expressed his hope that the several sales teams of Kinghelm and Slkor would maintain their fighting spirit, strengthen cooperation amid competition, and grab more orders in the market. He wished the company and his colleagues ever better performance!

After Two Consecutive Titles, We Are Still making progress——Slkor Interview with Sun Gaofei 2026-06-11
After winning the monthly sales team championship of the company's "A-team" for March and April, and with core member Luo Yanping winning individual sales champion twice, Sun Gaofei, Director of Sales Department I at Slkor, is leading his team to challenge for a third title. During the interview, he said, "The current state of our team is: going up the mountain to hunt tigers, and even the tigers are afraid of us." He then laughed, "But that's just an inside joke. Winning this championship is the result of everyone's hard work." Song Shiqiang, General Manager of Kinghelm & Slkor, presenting an award to Sales Department I Sun Gaofei majored in Applied Electronic Technology in college. After graduation, he worked in R&D for three years. His technical background has been a great help in leading the team – clients' technical staff are willing to have in-depth conversations with him, and he can directly help team members solve problems. However, when talking about the methods for winning the championship, he focused on team operations. His thinking is very clear: first break down the team's goals for each person, then have each person implement them with specific clients. In March, they proactively managed demand by having some clients place orders early. Entering April, he anticipated that this early consumption would lead to a slowdown, so he quickly adjusted the strategy – requiring the team to dig deeper into existing clients for other product models to generate incremental performance. "Since clients are already cooperating with us, their trust in us is very high." The effect of this deeper digging showed up in April, and the team fought another outstanding performance battle. Song Shiqiang, Luo Yanping, Sun Gaofei In his view, everyone's strategies are quite similar, and the most critical factor for success is the team's mindset. "One characteristic of our team is that whenever I say we need to push for performance, everyone is full of confidence and enthusiasm." The atmosphere where everyone is striving and trusts each other is the true competitive edge. After Luo Yanping won the individual sales champion for two consecutive months, Sun Gaofei specifically asked her to give a full-process sharing session – covering everything from client development, client follow-up, securing orders, to delivery schedule management, payment collection, and client maintenance. "Once a benchmark is set, everyone realizes this is not the ceiling, but the highest flag for now, and everyone wants to chase it." That sharing session received a good response within the team, especially for new members who were unclear about their goals; after listening, they knew in which direction to focus their efforts. Sales Department I champion trophy and mobile red flag The team's ability to charge ahead would not be possible without strong support from the back end. Sun Gaofei repeatedly mentioned the importance of the Slkor brand's reputation and cross-departmental cooperation: "The brand effect is very significant. Now the Slkor brand has gained recognition in the market, and the number of daily inquiries is stable. With timely cooperation from the supply chain, warehouse, and finance departments, we are able to close the deals. Performance is not just about the sales team fighting for orders; it is accomplished together by everyone." Sun Gaofei, Director of Sales Department I, during the interview Having served as Director of Sales Department I for over two years, Sun Gaofei believes the two most critical things in leading a team are: helping members solve problems and fairly distributing benefits. "As the team leader, you must solve problems satisfactorily, not just paint a rosy picture without taking action." He gave an example: while a team member was on maternity leave, her client in Zhongshan had a complaint. He immediately rushed there with an engineer and resolved the issue that same day. "Salespeople have sharp eyes; they know very well whether you can truly help them solve problems." Sun Gaofei's "Standardized Summary of Master-Apprentice Training" In terms of training newcomers, Sun Gaofei's first step is to "give a preventive shot". "In the semiconductor industry, no newcomer can achieve a breakthrough immediately after joining. Real growth comes from starting with small clients and moving to large ones, from following sample trials to mass production – this is a long process. But once you succeed, one good project can bring continuous returns for three to five years." In terms of specific coaching, he emphasizes eight words: "Be proactive, act with integrity." "Newcomers are confused when they join; we assign them mentors, but you must take the initiative to ask. The principle of our Sales Department I is that whenever a newcomer asks a question, we share everything we know." He says he has taught many people, but how much they learn depends on their aptitude. "The person who is proactive will definitely learn the fastest." Sun Gaofei training new salespeople on professional knowledge Slkor semiconductor product series Looking ahead to the semiconductor market in May, Sun Gaofei admitted that this time of year is usually peak season, but this year there is a slowdown, with even fewer clients asking for quotes. The team is currently adopting new strategies to maintain performance growth, but he is not comfortable disclosing them in advance. "It's not good to talk about things that haven't materialized yet." As for whether they can win the championship for the third time, his answer was very straightforward: "Stay tuned." General Manager Song Shiqiang expressed his hope that the several sales teams of Kinghelm and Slkor would maintain their fighting spirit, strengthen cooperation amid competition, and grab more orders in the market. He wished the company and his colleagues ever better performance!

The company's vision is that after 30 years of unremitting efforts, colleagues will make Slkor a "leading enterprise in the semiconductor industry"! 1.1 Name: Slkor DW03 Lithium Battery Protection Application Solution 1.2 Application: Single-cell lithium-ion battery pack; lithium polymer battery pack 2. The chip comes in a SOT23-5 package. 2.1 Product Features The DW03 product is a highly integrated solution for protecting single-cell lithium-ion/lithium polymer rechargeable battery packs. The DW03 includes an advanced power MOSFET, high-precision voltage detection circuits, and delay circuits. The DW03 provides all necessary battery protection functions such as overcharge, over-discharge, overcurrent, and short circuit, with very low power consumption during operation. This chip is not only designed for mobile phones but is also suitable for all kinds of information products that require lithium-ion or lithium polymer rechargeable batteries for long-term power supply. 2.2 The DW03 monitors battery voltage and current, and protects a single-cell rechargeable lithium battery from damage due to overcharge voltage, over-discharge voltage, overcharge current, over-discharge current, and short circuit by disconnecting the charger or load. The system has a simple external circuit. The MOSFET is built-in, with a typical equivalent resistance of 65mΩ. 3.1 Charger detection; 0V battery charging function; internally set delay time; high-precision voltage detection. 3.2 Low quiescent current: Normal operating current: 2.8uA; Standby current: 1.5uA; RoHS and lead-free compliant. 4. Slkor DW03 Lithium Battery Protection Application in Electric Shaver Solution: Figure 1 Figure 2 Figure 3 Application Principle Slkor single-cell lithium battery protection DW03. The DW03 includes an advanced power MOSFET, high-precision voltage detection circuits, and delay circuits, and is widely used in small household appliances. In the shaver application circuit shown in the figure, USB Type-C supplies power to charge the single-cell lithium battery. During charging, the MCU's ADC I/O port collects the charging voltage and displays the battery level on a digital tube. The charging circuit is built with Slkor SL4056 charging management and simple peripheral circuits. In the motor drive section, Slkor 3400 MOSFET is used, and the MCU I/O port collects key signals to control the motor on/off. DRV is the gate drive signal. When the MCU detects that the key is pressed, DRV outputs a high level and the shaver starts to rotate. 5.1 Figure 1 is only a reference circuit for the MCU to collect lithium battery charging. Note that the DW03 connects to the positive terminal of the lithium battery through a 100R resistor, pin 2 of the chip connects to the negative terminal of the lithium battery, and pins 4 and 5 connect to GND. Users can follow the specifications to design and easily build a corresponding single-cell lithium-ion battery protection circuit. The DW03 protects a single-cell rechargeable lithium battery from damage due to overcharge voltage, over-discharge voltage, overcharge current, over-discharge current, and short circuit. If no abnormal conditions are detected, the output transistor remains on, and charging and discharging can switch freely. This is called normal operation mode. During normal discharging, when the battery voltage drops below the over-discharge detection voltage (VDL) and the duration reaches or exceeds the over-discharge voltage detection delay time (TDL), the DW03 disconnects the battery from the load and stops discharging. This is called over-discharge voltage condition. In normal operation mode, when the discharge current is equal to or higher than the set value (VM voltage is equal to or higher than the overcurrent detection voltage) and the duration reaches the over-discharge current detection delay time, the DW03 turns off the discharge FET and stops discharging. This is called over-discharge current condition. During normal charging, if the VM voltage drops below the charge detection voltage (VCHA) and the duration exceeds the overcharge current detection delay time (TCU), the DW03 turns off the charge FET and stops charging. This is called abnormal charge current detection, etc. 5.2 In Figure 2, the bidirectional TVS for surge protection is Slkor SMF5.0CA, with VRWM voltage of 5.0V and excellent clamping capability, with a peak pulse power capability of 200W under 10/1000 µs waveform. Q2 and Q4 are both Slkor MOSFETs. The MCU enable signal controls Q2 to turn on Q4, and after Q4 conducts, Type-C outputs voltage VCC to power the load. 5.3 In Figure 3, D4 and D5 mainly serve as a battery and Type-C power switching circuit. When the charger is unplugged, the lithium battery supplies power. D4 and D5 are Slkor 1N5819WT Schottky diodes, with reverse leakage current of 1uA, voltage rating of 40V, maximum forward current of 1A, and low forward voltage drop, making them very suitable for low-current applications such as MCUs. 6.

Song Yuanming's Speech at Huaqiang Lecture: The Path to Global Branding for Kinghelm and Slkor 2026-06-05
On May 16, 2026, Song Yuanming, International Director of Kinghelm/Slkor, was invited to speak at the Huaqiang Lecture. Centering on the theme "The Path to Global Branding for Domestic Brands," he shared practical experience in globalizing Chinese semiconductor brands with fellow professionals in the electronic components industry. Drawing on Kinghelm and Slkor's recent explorations and achievements in overseas markets, he systematically deconstructed how domestic brands can break through from "being seen" to "being chosen," from building a digital marketing matrix to listing on international platforms. Song Yuanming, International Director of Kinghelm/Slkor Global Strategy: From "Passive Involution" to "Proactive Breakthrough" During his speech, Song Yuanming pointed out that the domestic electronic components market is facing intensified homogeneous competition, with price wars continuously squeezing profit margins, making going global an imperative choice. At the same time, the evaluation criteria of overseas customers are also changing: technical capability, delivery stability, and brand credibility are gaining more importance. Engineers and procurement personnel increasingly prefer to find suppliers through Google, Bing search, and industry platforms. "Whoever is seen first and appears more professional gets more inquiries and orders." Based on this insight, Kinghelm and Slkor have systematically built an overseas digital marketing matrix in recent years, gradually developing a global path of "search → inquiry → sampling → repeat purchase." Song Yuanming sharing SEO and GEO optimization Four Core Levers to Build an Overseas Marketing Closed Loop Song Yuanming summarized overseas marketing into four core stages, forming a complete closed loop from traffic to orders.

Kinghelm Electronics Company Development Milestones Slkor Semiconductor Company Development Milestones Kinghelm and Slkor’s Song Shiqiang are the first to systematically define and promote the 'Huaqiangbei Culture.' He is the first scholar to elevate the entrepreneurial model of Huaqiangbei’s spontaneous market into a theoretical framework. Song Shiqiang distilled the core values of 'daring, innovation, resilience, and pragmatism' into the essence of Huaqiangbei Culture and summarized the industrial upgrade path of 'imitation – improvement – innovation.' He proposed that 'a one-meter counter is an innovation unit,' representing a microcosm of entrepreneurial spirit. Small businesses are the vital capillaries of societal development, unlocking unprecedented value recognition and energizing Huaqiangbei’s innovative ecosystem. Song also identified the survival and development principles of Huaqiangbei as 'light assets, fast iteration, high conversion, and information-driven.' He innovatively introduced the concept of Huaqiangbei as the 'supply chain reservoir' for the electronics industry, explaining how it regulates production inventory, efficiently matches supply and demand, and buffers industrial ecosystem risks. This theory has become one of the foundational theoretical frameworks for understanding the rapid development of China’s post-reform electronics industry ecosystem. Kinghelm, founded by Song Shiqiang, specializes in the Beidou GPS navigation antenna field, contributing to the development of domestic navigation and positioning systems.
