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 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.

As a key member of the company's human resources team, she has worked meticulously and effectively in talent acquisition, team building, and new employee training, allowing the sales team to focus on their work without worry. Kinghelm/Slkor March Honor Roll The March recognition event has concluded successfully. These achievements are a vivid reflection of Kinghelm and Slkor's development philosophy of "performance-oriented, team-based." Whether it's the front-line sales team or the support staff in the back, every part provides solid support for the company's growth. Now the April challenge has begun, and all teams are fully engaged in battle mode. Who will be the next "A-Team" champion? We'll find out at the end of the month. 【Introduction to Kinghelm and Slkor】 Kinghelm Electronics and Slkor Semiconductor, both headquartered in Shenzhen, are invested and operated by Mr. Song Shiqiang. For over a decade, they have advanced hand in hand, following a high-quality development path for domestic brands. Kinghelm's headquarters include an IDC center and a distribution warehouse; the lab in Tangxia, Dongguan is equipped with a fully anechoic chamber, network analyzers, and other instruments, capable of performing high-temperature, double-85, and other tests, as well as new product prototyping and debugging. The manufacturing base is located in Luzhai County, Guangxi, with multiple automated production lines, fully staffed and well-trained teams that have undergone years of professional training and integration, ensuring on-time, high-quality, large-volume deliveries. Slkor, with the philosophy "Slkor, Move the Heart with Chips," treats colleagues with care, develops new products, and serves global customers. It has R&D offices in Beijing and Suzhou, and recently launched new "Slkor" brand products such as Hall sensors, ADCs, BMS, sensors, high-speed optocouplers, and passive crystals. The two brother companies share a common vision and philosophy, providing global electronics manufacturers with products and complete technical supporting services from the "chip" to the "terminal."

Slkor's Sales Department I has two successful "dark horses" who switched roles: one is Peng Ke, who came from the warehouse and has occasional bursts of performance, and the other is Luo Yanping, the sales champion for March and April and the interviewee here. Both have achieved career breakthroughs through their own efforts as Slkor has grown rapidly. Luo Yanping moved from customer service to sales, and after a long period of accumulation, her performance took off in 2026. In a recent interview, she shared her sales experience and strategies, revealing the growth and perseverance of a sales professional. Luo Yanping, Slkor Sales Department I In Luo Yanping's view, "grinding it out" is the key to winning double championships; luck is just the icing on the cake. Her sales secrets are simple: deep professional knowledge, customer segmentation and focus, consistent follow-up, and proactive problem-solving. Her previous experience in customer service gave her a deep understanding of customer needs – short-term performance may rely on luck, but to maintain stable results over the long term, only persistent effort and continuous accumulation, winning customer trust with professionalism, are true strengths. General Manager Song Shiqiang (center) presents the champion trophy to Luo Yanping From first contact to closing a deal, Luo Yanping summarized five key steps: understanding real needs, matching professional solutions, addressing core concerns, timely follow-up to lock in the order, and after-sales maintenance for repeat purchases. She says the first step is very important – many salespeople rush to promote products while overlooking the customer's real pain points. She uses an A-B-C customer segmentation method to focus her energy on high-value clients, while saving time with standardized workflows to ensure every interaction creates real value for the customer. This helps maintain strong relationships with key clients while also covering more potential opportunities. Luo Yanping at her workstation in Slkor Sales Department I Sales in the semiconductor industry have high professional demands – stock shortages, delivery delays, and demanding customers – Luo Yanping has experienced all of these. Her approach: never over-promise or over-sell just to get an order. When problems arise, she honestly informs the customer, provides multiple alternative solutions, coordinates internal and external resources, and actively follows up throughout the process. She believes that facing problems without avoidance or blame, and actively looking for solutions, is the most basic quality of a salesperson. Being able to do this is the foundation for earning long-term customer trust. Slkor semiconductor product series Asked about how she has changed since entering the industry, Luo Yanping said that when she first started, she was afraid of rejection and easily discouraged. Now she is more stable, resilient, and can face rejection calmly, actively solving problems without overthinking. This mental maturity has been honed through real-world experience. The company's support has also given her confidence – stable product supply, brand backing, and team experience all help her do her job with greater assurance. General Manager Song Shiqiang often says, "Only by building a strong brand can we create a better platform for our salespeople, allowing them to focus on fighting on the front lines." General Manager Song Shiqiang (6th from left) with the Slkor Sales Department I team As a senior salesperson in the team, Luo Yanping has gradually taken on the responsibility of mentoring new hires: "Currently, I focus on three areas: process standards, product knowledge, and customer follow-up skills." Her advice for newcomers is fourfold: first, thoroughly learn the industry and product basics; second, keep a calm mindset and don't fear rejection; third, persist in proactive follow-up; and fourth, learn to segment customers and review your work daily. From customer service to sales champion, her growth path proves one thing: there is no shortcut in sales – steady and solid effort is the best shortcut. This also embodies the corporate culture of Kinghelm and Slkor: "Integrity, Diligence, Resilience, and Attention to Detail." Kinghelm and Slkor corporate culture

Author: Chen Qianhui, Slkor Data Entry Specialist With the spring breeze and the morning sun, all employees of Kinghelm and Slkor set off on a spring trip to Maluan Mountain on March 28. This trip was not only a team-building activity to get close to nature and relax, but also a vivid practice of living out the company culture and strengthening team spirit. Amid the mountains and waters, every employee deeply experienced the core values of "integrity, diligence, resilience, and attention to detail," and felt the warmth and mutual help among colleagues, like one big family. In the early morning, we gathered at the north gate of Maluan Mountain Park. Colleagues were chatting and laughing, with smiles of anticipation on their faces. We shared breakfast, talked about our expectations for the trip, and walked forward together. The mountain path was winding. Not long after we started, we saw a waterfall pouring down in front of us. From a distance, it cascaded with a thunderous roar, majestic and breathtaking. Standing before it, we felt relaxed and open-hearted. Everyone was deeply impressed by the magnificent beauty of nature. Maluan Mountain Waterfall Then we arrived at the former site of the Gengzi Uprising. Everyone took photos to mark the visit, sharing what we had seen and heard along the way. All employees lined up neatly in front of the Luo Ancestral Hall for a group photo. The camera captured not only our smiles but also the cohesion of the Kinghelm and Slkor team — a vivid portrayal of our corporate spirit: "One family, one heart, working together." Kinghelm & Slkor group photo at Maluan Mountain 2026 After that, we continued to the next spot. Along the way, we climbed over hills and crossed mountains. The weather wasn't very cooperative — a light rain began to fall, and mist spread through the forest, making us feel like we were in a fairyland. The stone paths became slippery, and the road ahead was hidden in the fog. Colleagues had to support each other as we moved forward. After several hours of trekking, we finally crossed Maluan Mountain, fully embodying the company's spirit of "perseverance and rising to challenges." On the way down, we encountered another waterfall. By then, the rain had gradually stopped. Seeing the waterfall again, my feelings were somewhat different — less of the initial shock, and more of a sense of relief after the storm, and even more, an unspoken understanding and mutual appreciation born from fighting side by side. This appreciation came from the mutual help among colleagues, the strength of the team, and the nourishment of our company culture. Kinghelm & Slkor Corporate Culture This hiking activity gave me a deeper understanding of our corporate culture. Hiking is like work — there will be steep slopes and storms, just as we encounter difficulties and challenges on the job. But as long as we hold onto our "integrity" — staying true to our principles and keeping our feet on the ground — our "diligence" — striving for excellence and constant improvement — our "resilience" — facing difficulties head-on and never giving up — and our "attention to detail" — being meticulous and precise — there is no challenge we cannot overcome, no peak we cannot reach. It is precisely because all employees consistently live out this corporate culture and belief that, under the leadership of General Manager Song Shiqiang, our company has been able to overcome one obstacle after another and grow stronger. In the future, we will bring the mutual support and resilient spirit from the hiking trail into every detail of our daily work. We will move forward side by side, with one heart, with greater enthusiasm and firmer belief, contributing to the company's development and heading together toward a bright future. General Manager Song Shiqiang (2nd from left) chatting and laughing with colleagues as they walk up the mountain

Shenzhen Slkor Micro Semiconductor Co., Ltd., with its technical backbone comprised of talents from Tsinghua University and Yonsei University in South Korea, leads the company's development with new materials, new processes, and new products. It possesses internationally advanced third-generation semiconductor silicon carbide (SiC) power device technology. Founder Mr. Song Shiqiang has always placed great emphasis on the development of new technologies and the reserve of new products. Slkor also focuses on the layout of intellectual property, which has become a barrier in the fiercely competitive market and a firewall for its brand. Following the grant of three utility model patents by the China National Intellectual Property Administration in March 2022—"A MOSFET Packaging Structure," "An IGBT Power Module Installation Structure," and "A Fixture for Transistor Forming and Processing"—another utility model patent, "A Heating Device for Thyristor Processing," was granted in April 2022. This further strengthens Slkor's intellectual property portfolio and demonstrates the continuous enhancement of the company's capabilities. Utility Model Patent Certificate for "A Heating Device for Thyristor Processing" Slkor's product range is increasingly diverse. Products for industrial applications include: silicon carbide (SiC) diodes, silicon carbide (SiC) MOSFETs, IGBTs, fifth-generation ultra-fast recovery power diodes, etc., meeting the demand for high-performance products in industries such as new energy vehicles, high-end equipment, communication and power equipment, solar photovoltaics, and medical devices. Products for civilian consumer applications include: power devices such as high, medium, and low-voltage MOSFETs, thyristors, bridge rectifiers, etc.; Schottky diodes, ESD protection diodes, TVS transient suppression diodes, general-purpose diodes and transistors; and series such as power management chips, Hall sensors, and high-speed optocouplers. These are widely used in smartphones, laptops, robots, smart homes, IoT and IoV (Internet of Vehicles), LED lighting, 3C digital products, and more. Precisely because Slkor's brand products are becoming increasingly diverse, protecting one's rights and interests requires using legal tools, and intellectual property is the first line of defense. Previously Granted Utility Model Patent Certificate for "A MOSFET Packaging Structure" This patent is also an achievement of advocating technological innovation and transformation, comprehensively enhancing the company's product technological content and practical value. It is a tangible manifestation of the remarkable results achieved by the R&D team led by Slkor's General Manager Mr. Song Shiqiang, consisting of members from Yonsei University and Tsinghua University, who overcame numerous challenges through repeated experimentation during the development process. Utility Model Patent Certificate for "An IGBT Power Module Installation Structure" Granted in March Through years of continuous accumulation and consolidation, Slkor has built a solid foundation, made steady progress, and achieved performance growth. The leadership of General Manager Mr. Song Shiqiang has played a crucial role. Mr. Song Shiqiang deeply understands that enterprise development is not just about people; to make a company stand firm at the forefront, its comprehensive strength must also keep pace. Utility model patents and other intellectual property rights are only the first step. Upgrades have also been made in product patents, corporate management systems, and digital management, gradually realizing the enterprise's digital transformation. Utility Model Patent Certificate for "A Fixture for Transistor Forming and Processing" Granted in March With strong technical support and intellectual property, Slkor is inevitably moving from quantitative to qualitative change in the near future. This brings Slkor closer to its goal of going public, and even surpassing it, showcasing Slkor Semiconductor's solid strength in the domestic semiconductor industry and contributing its share to the "China Chip" endeavor!
