Mr. Song Shiqiang, the General Manager of Kinghelm and Slkor Semiconductor, stated that the electronic information industry is still in a strong trend, and there are opportunities for further development in Huaqiangbei. As of now, the disruptive new technologies that drive the "Kondratieff Cycle" of the economy have not yet emerged, and we are still in the era of electronic information. In recent years, developments such as AI, metaverse, Microsoft's ChatGPT, and Huawei's PanGu large model are on the rise, and the ongoing developments in electrification, informationization, and digitization are all closely tied to electronic components.

From large-scale military equipment like warships and missiles to everyday items like smart locks and televisions, from Apple's smartphones to Kinghelm's development of BeiDou GPS navigation products, all rely on chips. According to data from the General Administration of Customs of China, the total import value of chips in China for the first six months of 2023 decreased somewhat but still amounted to 162.609 billion US dollars.

Through incomplete statistics, it's estimated that nearly $600 billion USD worth of electronic components are imported, produced, processed, consumed, and exported through mainland China each year. Not only is the market capacity vast, but the diversity of products and the industry pe*******on are also strong, comparable to the leaders in the semiconductor industry chain.

Mr. Song Shiqiang, as a research expert on Huaqiangbei, noted that Huaqiangbei is a hub for electronic components and smart hardware. With a robust market capacity rooted in mainland China and a geographical advantage being situated near Hong Kong in southern China, the annual sales of electronic components have exceeded 240 billion yuan in recent years. This provides ample room for survival and adjustment in the industry.

Zhou Zhaoquan, the Sales Director of Kinghelm (www.kinghelm.com.cn), introduces the basic structural components of connectors as follows:

1. **Contacts:** Contacts are the core components of connectors that facilitate electrical connections. They typically consist of male contacts and female contacts, which, when mated, complete the electrical connection. Male contacts, also known as pins, are rigid components that come in cylindrical (round pins), square (square pins), or flat (blade) shapes. They are usually made of brass or phosphor bronze. Female contacts, or sockets, are critical components that rely on their elastic structures to deform elastically when engaged with male pins, creating a tight connection through elastic force. There are various types of socket structures, including cylindrical (split, chamfered), fork type, cantilever beam type (longitudinally slotted), folded type (longitudinally slotted, 9-shaped), box type (square socket), and hyperbolic thread spring socket.

2. **Insulator:** The insulator, also referred to as the base or insert, arranges the contact elements in the required positions and spacing and ensures the insulation performance between contacts and between contacts and the shell. Good insulation resistance, voltage resistance, and ease of processing are the basic requirements for selecting insulating materials for manufacturing insulators.

3. **Shell:** The shell, also known as the outer shell, is the connector's external cover. It provides mechanical protection for the inner insulating insert and pins and ensures alignment during plug and socket engagement, thereby securing the connector to the equipment.

4. **Accessories:** Accessories include structural accessories and mounting accessories. Structural accessories include items like retaining rings, keying plugs, guide pins, guide posts, latches, cable clamps, sealing rings, sealing gaskets, etc. Mounting accessories include screws, nuts, bolts, spring rings, etc. Most accessories have standard and general-purpose versions.

Zhou Zhaoquan emphasizes that in addition to excelling in products like BDS and GPS antennas, Kinghelm (www.kinghelm.net) has also been actively involved in RF and signal connectors in recent years. They have launched a series of Kinghelm connectors, plugs, terminal products, and more into the market.

Why is RFID Technology (Radio Frequency Identification) so important in the future of digitization, informatization, and automation? What unique advantages and application value does RFID system possess? What are the application scenarios of RFID systems in the industrial field? Who are some well-known industrial RFID manufacturers domestically and internationally? Why is Kinghelm Electronics positioning itself in the RFID product landscape? According to Deng Haifeng, Director of Kinghelm (www.kinghelm.com.cn), in recent years, with the advancement of digital transformation and smart manufacturing, coupled with the continuous improvement of industrial automation, RFID (Radio Frequency Identification) technology, as a crucial automatic identification and data collection technology, is increasingly being applied in the industrial domain. It's being integrated and interacted with various digital systems like ERP, MES, and WMS that are extensively used by enterprises. It plays a significant role in reducing errors in manual data collection, saving labor and operational costs, achieving product tracing and tracing, meeting specific process requirements, and enhancing production efficiency and product quality. The future market outlook is promising.

In the past industrial scenarios, commonly used data identification technologies mainly included barcodes, QR codes, and RFID technology. Among these, barcode technology is widely used but has various limitations: reading barcodes requires matching light sources, and there are strict requirements for the brightness of the light source. Alignment with the light beam in the visual range is necessary to successfully read information. Barcode recognition demands high mechanical precision, and factors like tray deformation can lead to barcode reading failures. Scanning needs to be done one by one, with each scan only capable of reading one barcode, resulting in low efficiency. Barcodes are susceptible to wear, dirt, and contamination, leading to a short lifespan. Additionally, they cannot be modified and reused after printing a new barcode, limiting their data capacity to reading only, and not writing data. Despite their low cost, printing a new barcode for each piece of data adds to the expense. Furthermore, one-dimensional barcodes must be connected to a database system for interpretation. These limitations make barcode technology unable to meet the demands of complex industrial application scenarios. Two-dimensional barcodes have broad application scenarios and resolve the issue of information capacity, while also introducing error correction capabilities. They can be laser-engraved onto surfaces to enable reading and anti-counterfeiting functions. However, they still have certain drawbacks. Kinghelm's FRID barcode products can address these issues.

Kinghelm Electronics has been dedicated to the research and production of radio frequency and microwave products. The FRID chips and tags under the Kinghelm brand (www.kinghelm.net) have been widely adopted by customers.

Mr. Chen Suwei, the Sales Engineer at Kinghelm (www.kinghelm.net), introduces that the fundamental performance of connectors can be divided into three main categories: mechanical performance, electrical performance, and environmental performance. Among these, mechanical performance primarily includes insertion and withdrawal forces and mechanical durability.

In terms of mechanical performance, the insertion force is crucial for the connector's functioning. It comprises insertion force and withdrawal force (also known as separation force), each having different requirements. Relevant standards specify maximum insertion force and minimum separation force, which suggests that, from a usability standpoint, the insertion force should be minimized (leading to Low Insertion Force, LIF, and Zero Insertion Force, ZIF, structures), while the separation force should not be too low to maintain reliable contacts. Another essential mechanical aspect of connectors is their mechanical durability. Mechanical durability, referred to as mechanical operations in the national standard GB5095, evaluates whether a connector can successfully complete its connecting function (e.g., contact resistance) after a specified number of insertion and withdrawal cycles. One cycle involves one insertion and one withdrawal. The insertion force and mechanical durability of connectors are influenced by factors such as contact structure (normal force), plating quality of the contact area (sliding friction coefficient), and alignment precision of the contact arrangement.

Mr. Chen Suwei from Kinghelm emphasizes that in high-current connectors, contact force is a fundamental factor. Without sufficient contact pressure, the use of excellent conductive materials would be ineffective. If the contact force is too low, there may be displacement between the wire and the contact piece, leading to oxidation and contamination, which in turn increases contact resistance, causes overheating, and affects the connector's performance and lifespan.

Kinghelm, based on its research and production of BDS/GPS RF and small signal connectors, continuously introduces a series of products, including board-to-board connectors, wire-to-board connectors, wire-to-wire connectors, piercing connectors, and type-c connectors.

Kinghelm Electronics' Sales Director, Zhou Zhaoquan, stated that the advancements in Bluetooth technology have brought new opportunities for industrial development. Features such as LE Audio, responsive periodic advertising (PAwR), high-precision distance measurement, Bluetooth 2M low-energy physical layer (LE 2M PHY), and low-power Bluetooth specifications in the 6 GHz frequency band have revitalized Bluetooth. With the support of these technologies, Bluetooth is expanding its applications beyond audio and data transmission to include location services and device network applications. It can be combined with Kinghelm's Beidou GPS positioning and navigation antenna connectors to enhance the functionality and accuracy of smart terminal products. Bluetooth applications are gradually changing device usage habits. For example, with LE Audio, Auracast broadcasting allows audio source devices to simultaneously stream one or multiple audio streams to TWS earphones, speakers, and other receiving devices.

Digital keys are also common applications in smart living. Using mobile terminals, Bluetooth can control digital locks for cars, homes, or offices. Zhou Zhaoquan mentioned that he had a friend who found a store on Taobao and used Bluetooth RF technology to pair with a Volkswagen car key, saving a significant amount of money. Bluetooth technology is also applied to electronic shelf labels, connecting them to retail systems to provide real-time updates of product information on shelves. There are many other emerging Bluetooth tags derived from this, which can connect to the surrounding environment and form a small IoT ecosystem.

Under the new Bluetooth technology, networked lighting control is also achievable. Networked lighting systems form an intelligent network through Bluetooth, where each device serves as both a sensor and an addressable transceiver. After the success of TWS Bluetooth earphones, Bluetooth technology will find even more applications. Kinghelm, as a manufacturer, has developed chip ceramic antennas such as KH2012, KH3216, KH5220, KH6010, which can directly replace brands like Murata, TDK, Taiwan Wan Cheng, Yongye, ACX, Huake, etc. These antennas are used in products from Apple AirPods, Huawei, Xiaomi, Samsung, Awei, and cover Bluetooth earphone products from Qualcomm (CSR), Hengxuan (BES), MediaTek, LuoDa (Airoha), Realtek, Actions, AMS, JL, and others.

Mr. Zhou Zhaoquan, the Sales Director of Kinghelm Electronics (www.kinghelm.net), provides some explanations and definitions related to RF microwave antenna technology indicators:

1. Standing Wave Ratio (SWR): SWR, also known as Voltage Standing Wave Ratio (VSWR), is a measurement of the voltage standing waves in an antenna system. It is calculated using the formula: SWR = (1+K) / (1-K), where K represents the reflection coefficient. The value of K ranges from 0 to 1. SWR is a dimensionless quantity that indicates the match between the antenna and the radio transmitter. An ideal SWR value is 1, indicating that no reflected waves occur (K=0) and all the high-frequency energy is radiated. If the SWR value is greater than 1, it signifies that a portion of the radio waves is reflected back, resulting in heat generation and an increase in the temperature of the transmission line. The reflected waves can also cause high voltages at the transmitter's output, potentially damaging the transmitter. An SWR value of infinity (K=1) represents complete reflection, where no energy is radiated.

2. 1 dB Compression Point of an Amplifier (P1dB): The 1 dB compression point, denoted as P1dB, is a measure of an amplifier's linearity. Within the linear dynamic range, the amplifier's output power increases linearly with the input power. However, when the input power exceeds a certain threshold, the amplifier enters the nonlinear region, and the output power no longer increases linearly with the input power (approaching a ceiling). The 1 dB compression point is defined as the output power at which the gain of the amplifier drops by 1 dB from its linear gain. It is represented as OP1dB (similarly, IP1dB refers to the input 1 dB compression point). Typically, when the power exceeds P1dB, the gain rapidly decreases, reaching a maximum or completely saturated output power (ceiling) that is 3-4 dB higher than P1dB. The 1 dB compression point (P1dB) is an indicator of the amplifier's output power capability.

6. Third Order Intercept Point (IP3): The Third Order Intercept Point, denoted as IP3, is a parameter that measures linearity or distortion performance. A higher IP3 value indicates better linearity and less distortion. It can be specified as the Output Third Order Intercept Point (OIP3) or the Input Third Order Intercept Point (IIP3).

3. Scattering Parameters (S-parameters): S-parameters, also known as scattering parameters, describe the behavior of microwave circuits or components. S12 represents the reverse transmission coefficient (isolation), S21 represents the forward transmission coefficient (gain), S11 represents the input reflection coefficient (return loss), and S22 represents the output reflection coefficient (return loss). In the terminology of vector network analyzers, the reference channel (R) is used to measure the incident wave. Channel A is responsible for measuring the reflected wave, while channel B measures the transmitted wave.

Kinghelm Electronics (www.kinghelm.com.cn) is a national high-tech company specializing in the technical research, product design, manufacturing, and sales of microwave RF signal transmission/reception, miniature electronic connectors, and interconnect system products. Kinghelm offers a range of products under the Kinghelm brand, including Beidou GPS antennas, RF adapters, electrical data signal connectors, terminals, plugs, automotive and motorcycle wire harnesses, industrial medical connectors, customized military antenna connectors, and more.

Here are several definitions and explanations related to RF antenna technology indicators:

1. Decibel (dB): dB is the abbreviation for "decibel," which is derived from the English word "decibel," representing one-tenth of a bel. The term "bel" is named after the eminent scientist Alexander Graham Bell, who obtained the patent for the invention of the telephone in 1876 and made significant breakthroughs in its application and development (the renowned Bell Laboratories has its origins in this). When using the dB symbol, the "B" should be capitalized (as it refers to a name). Similarly, other units of force and electricity, such as Newton, Gauss, Faraday, Henry, Ohm, Volt, Ampere, and Watt, are also named after individuals. Due to the inconvenience of using the unit "Bel" (which is relatively large), the more commonly used unit is one-tenth of a bel, known as decibel (dB). The use of dB in electrical engineering is derived from acoustics.

2. Signal-to-Noise Ratio (SNR): The signal-to-noise ratio is the ratio of the effective power of the signal to the effective power of the noise (usually expressed in logarithmic form), and its unit is dB. SNR = 10 lg(PS/PN), where PS and PN represent the effective power of the signal and noise, respectively. In terms of voltage amplitude, the relationship can be expressed as SNR = 20 lg(VS/VN), where VS and VN represent the "rms" voltage of the signal and noise, respectively. A higher signal-to-noise ratio is desirable, whether at the input or output.

3. Noise Figure (NF): To measure the noise characteristics of a linear circuit (such as an amplifier) or a system (such as a receiver), it is common to introduce a measure of the internal noise level of the circuit or system. This measure allows differentiation of the performance of different circuits in terms of noise and facilitates measurement. A widely used measure of noise is called the noise figure (NF).

Kinghelm is dedicated to providing high-quality products and services in the field of microwave RF signal transmission/reception, miniature electronic connectors, and interconnect systems. The company's expertise and comprehensive product range make it a trusted choice for customers seeking reliable RF antenna solutions and connectivity solutions for various applications.

Recently, mainstream media such as the People's Daily App, People's Financial Network, Securities Stock Network, International Financial Times, and Xinhua News have successively reposted the original article titled "Unveiling the Wealth Code of Shenzhen Huaqiangbei: Why Are There So Many Billionaires in Huaqiangbei?" by Song Shiqiang, a commercial expert of SLKORMICRO. China.com was the first to release the news on its front page. This is another instance where Mr. Song Shiqiang, the General Manager of Kinghelm (www.kinghelm.net)/SLKORMICRO (www.slkoric.com), after his remarkable articles such as "Research on Huaqiangbei," "Refuting Bloomberg's Article 'China's Underground Chip Market Attracts Desperate Automakers,'" and "The Past, Present, Future of Shenzhen Huaqiangbei," has been reposted by mainstream media both domestically and internationally. Mr. Song Shiqiang was the first to extract the essence of the "Huaqiangbei Spirit" and the "Huaqiangbei Culture." He believes that a culturally enriched Huaqiangbei possesses a soul, and that soul is characterized by innovation, daring to take risks, and embodying the human spirit of ordinary people who fear no hardships in the pursuit of a better life. Huaqiangbei, composed of immigrants and floating population, is built upon the risk-taking Chaoshan fishermen culture, integrated with the Hunan people's endurance and tenacity in the face of hardship, and combined with the traditional values of the electronic professionals from Sichuan and Chongqing who are known for their diligence and hard work. Huaqiangbei, located in the hardworking southern part of China, has been honed and refined in this environment. Driven by the progress of the times, this unique Huaqiangbei culture influences our thinking, shapes our behavior, promotes the Huaqiangbei brand, and propagates the values of Huaqiangbei. Like the legendary stories left behind by old Shanghai, Huaqiangbei leaves behind its own tales for us to reminisce about, allowing future generations to savor the essence of Huaqiangbei. Shenzhen Huaqiangbei is an open and spontaneous market, a place where money, people, goods, information, resources, opportunities, and efficiency abound. The government's intervention in the economy is minimal, primarily focused on providing services. In addition, the daring and opportunistic nature of the people in Huaqiangbei effectively combines the vast hardware product resources with the enormous market demand, leading to the creation of numerous billionaires. It is a product of the times, which can be considered the wealth code of Huaqiangbei! However, we must be vigilant and deeply reflect upon the historical prosperity brought about by the Grand Canal in Jing-Hang and the decline of cities like Detroit in the United States, which transformed into rust belts after the decline of the automotive industry.

Ms. Cheng Yujie, Deputy General Manager of Kinghelm, introduced that we have entered the era of the Internet of Things, where everything is interconnected. The long-awaited trillion-dollar market has finally arrived. It is estimated that by 2026, China's IoT IT spending will reach nearly $298.12 billion, accounting for about 1/4 of the global IoT investment, leading the world in investment scale. Although the IoT market appears huge, it is challenging to find a universal standardized solution to capture the fragmented market demand, as many solutions require customization. The small RF microwave antenna plays a crucial role in IoT solutions as an integral part of wireless devices. It converts energy from RF circuits into electromagnetic waves, enabling the radiation and transmission of information. The amount of energy radiated depends on the antenna's efficiency, while the intensity of radiation energy in specific spatial directions depends on the antenna's gain in those directions. We aim for all the energy from the RF transmitter to radiate in the intended direction, so both antenna efficiency and gain need to be as high as possible for directed radiation. Simultaneously, to minimize potential harmful interference to other RF devices, we need to regulate the energy radiated in any specific direction, thus requiring limitations on antenna gain. Kinghelm (www.kinghelm.net), established for 16 years, has been focusing on products such as Beidou GPS antennas, RF connectors, and adapters. We have set up microwave RF antenna testing laboratories in Tangxia, Dongguan, and antenna connector production bases in Liuzhou, Guangxi. We also accept customizations and mold development for non-standard antenna connectors, preparing for the upcoming explosion of the Internet of Things!
