Unwavering Initial Aspiration: A Road to Success from a Rented Room to the Science and Technology Innovation Board
In 2005, Zhou Maolin, fresh out of graduate school at Sun Yat-sen University, embarked on his entrepreneurial journey in a humble rented room, armed with his industrial automation experience accumulated at Midea Group. At that time, China’s electronics industry was experiencing explosive growth, but high-end testing equipment had long been monopolized by foreign giants, leaving domestic companies facing the dilemma of “not being able to afford it or use it properly.” “Could we develop testing equipment that is both affordable and easy to use?” This simple question became the initial aspiration behind the birth of Silingjie.
In the early stages of the business, the team focused on network communication technology services, accumulating technical expertise while keenly recognizing the urgent need for efficient testing solutions in the consumer electronics industry. In 2010, Silingjie made a crucial strategic transformation—abandoning its communication business and focusing on the automated testing track.
This decision stemmed from Zhou Maolin’s accurate assessment of market trends: “At that time, the types of signals that needed to be tested for a mobile phone expanded from 2G to 3G and 4G, and the number of testing points surged from dozens to hundreds. Traditional testing equipment simply couldn’t meet the demand.” The transformation was fraught with challenges. The team innovatively proposed a “controller + modular instrument” solution, breaking down the complex testing system into flexibly combinable functional modules. Customers could freely combine these modules according to their needs, quickly building testing solutions like “building blocks.” This breakthrough not only significantly reduced testing costs compared to imported equipment but also greatly improved testing efficiency. In 2017, leveraging this technological advantage, Silingjie entered Apple’s supply chain, becoming a core supplier for its PCB board testing, with products covering a full range of terminals including mobile phones, tablets, and smart wearables. “Apple’s certification process for suppliers is extremely rigorous, with each step, from technical parameters to production processes, undergoing multiple rounds of review,” recalled the R&D director of Silingjie. “Our team worked continuously in the lab for three months, ultimately achieving zero defects in the certification.” This dedication earned Silingjie the trust of a top international client and provided a valuable scenario for its technological iterations—the changing demands of Apple’s annual product iterations forced Silingjie to establish a “rapid response, continuous optimization” R&D system. On March 14, 2022, Silingjie successfully listed on the Science and Technology Innovation Board (STAR Market), becoming the first company from Panyu District, Guangzhou, to be listed on the STAR Market. At the listing ceremony, Zhou Maolin said emotionally, “From rented rooms to the capital market, we have always firmly believed that core technologies cannot be bought or begged for; we must forge them ourselves.” Technological Breakthrough: Modular Architecture Reconstructs the Industry Ecosystem Stepping into the laboratory of Silingjie’s new headquarters building, a PCB board testing device in operation immediately catches the eye: on a workbench of less than one square meter, the controller module, like a “brain,” precisely schedules eight functional modules, including digital sampling, RF testing, and audio analysis, simultaneously completing multi-dimensional signal detection of electricity, light, and sound. “This solution can replace traditional imported equipment costing millions of yuan, while significantly reducing costs,” explained the on-site engineer. This “one against many” magic stems from Silingjie’s unique modular technical architecture. The company has mastered 13 core technologies, forming an intellectual property system of 32 invention patents, 35 utility model patents, and 116 software copyrights. Its core controller module can flexibly adapt to dozens of functional modules, supporting customized needs in industries such as consumer electronics, semiconductors, and automotive electronics, truly realizing an integrated closed-loop service of “hardware + software.” At Meta’s virtual reality equipment testing line, Silingjie’s RF testing module is capturing signal fluctuations with micron-level precision; in BGI Genomics’ gene sequencer production workshop, high-precision signal processing modules ensure the accuracy of every test data point; in the field of new energy vehicle battery testing, multi-channel synchronous acquisition technology achieves millisecond-level response… “Our modular solutions are as open as ‘Lego,’ allowing customers to freely combine them according to their needs, and even participate in the joint development of functional modules,” said Silingjie’s marketing director. Behind this technological advantage is continuous and high-intensity R&D investment. The company’s R&D personnel consistently account for more than 50% of its workforce, and its annual R&D investment exceeds 20% of revenue, far exceeding the industry average. In 2023, the company’s core technological achievements were authoritatively appraised as reaching the advanced level in China, and it was featured twice in special interviews by CCTV, receiving high praise for its “small modules, big impact.” Ecosystem Empowerment: From Domestic Substitution to Global Competition and Cooperation On Silingjie’s client list, international giants such as Apple, Meta, and VIVO are listed alongside leading domestic companies such as BGI Genomics and Haige Communications, outlining its diversified layout of “international leaders + emerging fields.” “We not only want to replace imports, but also define industry standards,” Zhou Maolin announced at the opening ceremony of the new headquarters in 2025. The company will increase investment in building an AI testing laboratory to explore the deep integration of modular technology and artificial intelligence. This ambition stems from a profound understanding of industry trends. With the popularization of technologies such as 5G, IoT, and AI, industrial testing is evolving from single equipment to systematic solutions. Sillink’s modular architecture perfectly aligns with this trend—its Archon test system management software enables visualized orchestration of test processes, while its NYSATOOLKIT application software supports real-time traceability of test data, providing a “digital foundation” for intelligent manufacturing. In the semiconductor testing field, Sillink has collaborated with several leading companies on joint R&D, developing high-precision signal conditioning modules to meet the testing needs of advanced process chips; in the low-altitude economy sector, its RF testing solutions are helping drone companies overcome flight control bottlenecks; in the biomedical field, modular design significantly shortens the R&D cycle of medical equipment… “Our technology is like a ‘seed,’ taking root in different industries,” Sillink’s strategy director aptly put it. Panyu’s Fertile Ground: A Business Environment Nurturing Innovation “Sillink’s growth is inseparable from the fertile ground of Panyu,” Zhou Maolin has stated publicly on multiple occasions. From project initiation to the completion and commissioning of the new headquarters, the Panyu District Government provided comprehensive “nanny-style” services: significantly shortening the construction cycle through “phased construction permits,” enabling companies to “start construction immediately upon acquiring land” using a “parallel approval” mechanism, and addressing concerns such as talent settlement and children’s education through a “one-company-one-policy” approach. Panyu’s locational advantages also support Silingjie’s global expansion. As the geographical center of the Guangdong-Hong Kong-Macao Greater Bay Area, Guangzhou South Railway Station allows companies to reach core cities in the Greater Bay Area within one hour; the completion of major infrastructure projects such as the Shiziyang Channel further strengthens the radiation effect of the “one-hour industrial circle in the Greater Bay Area.” Under the guidance of Panyu’s “two axes and two belts” strategy, the Shiziyang Intelligent Manufacturing Innovation Park has attracted 75 high-end projects, forming industrial clusters such as intelligent connected vehicles and semiconductors, providing rich application scenarios for Silingjie’s technological iteration. “Here, companies can not only obtain policy dividends but also integrate into an innovative ecosystem,” Zhou Maolin remarked. The Panyu District’s ongoing “industry-academia-research-application” integration plan has helped Silingjie establish joint laboratories with universities such as South China University of Technology and Guangdong University of Technology, cultivating a group of compound talents who understand both technology and application scenarios. The Future is Here: Moving Towards a Global Industrial Inspection Giant Standing at the new starting point of its 20th anniversary, Silingjie has outlined a clear growth blueprint: on the one hand, it continues to deepen its presence in the consumer electronics field, consolidating its technological advantages through fourth-generation and fifth-generation modular products; on the other hand, it accelerates its expansion into emerging tracks such as semiconductors, low-altitude economy, and biotechnology. “Our goal is to become the ‘Intel’ of the industrial inspection field—not only providing products, but also defining industry standards,” Zhou Maolin revealed. The company is participating in the formulation of several national standards for modular inspection equipment and plans to establish R&D centers in Europe, America, and Southeast Asia to build a global service network. Two decades of hard work and progress have allowed Silingjie to leverage “small modules” to drive a large industry, and its dedication to cultivating its niche and breaking through barriers has exemplified the upgrading path of Chinese manufacturing. In this vibrant and opportunity-filled bay area, this hidden champion is setting sail with innovation as its sail, heading towards a broader horizon.
