Founded in 2004 with a registered capital of RMB 30 million, Beijing Raysun Weiye Technology Co., Ltd. ("Raysun") specializes in the planning, implementation and servicing of complete production lines for electronic assembly, micro-assembly and wire harness manufacturing. We deliver integrated hardware-and-software solutions covering advanced equipment, processes, production and testing, while also developing our own advanced manufacturing equipment to solve customers' real production pain points.
Our 3,000 m² production base is located in Pinggu, Beijing, with branches and offices in Shanghai, Xi'an and Chongqing. Our sales and service network covers all of China and extends into Southeast Asia.
Our core business spans three electronic-assembly fields: cable & wire harness processing and testing, SMT surface-mount technology, and micro-assembly & packaging. Beyond distributing advanced imported production and inspection equipment, we persist in independent R&D and have successfully developed in-house products such as the intelligent cable marking system, digital cable routing system, on-the-fly UV laser wire marking system and high-precision cable network testers — several of which fill technical gaps in China. We hold numerous software copyrights, invention patents and utility model patents, along with Beijing New Technology & New Product certification and international CE certification. In 2025, our in-house products won an Excellence Award in the "Maker Beijing" competition.
Raysun obtained GJB 9001C and ISO 9001 quality management system certification and the National High-Tech Enterprise certificate in 2017; the intellectual property management system certification in 2021; the Zhongguancun High-Tech Enterprise certificate and Beijing "Specialized & Sophisticated" SME certificate in 2022; ISO 14001 environmental and ISO 45001 occupational health & safety certification in 2023; and the Beijing Intellectual Property Pilot Unit certificate and the "Raysun Weiye" trademark in 2024.
Guided by customer needs, driven by technological innovation and rooted in our people, Raysun upholds the philosophy of "Together Rising With Raysun" — providing integrated, diversified, refined and customized one-stop, turnkey services in complete electronic assembly solutions.
A complete range of wire harness processing and testing equipment — covering marking, cut-to-length, stripping, assembly (soldering, crimping), bundling, testing and accessories — meeting diverse process requirements.
A full portfolio of high-, mid- and entry-level SMT production and inspection equipment, including fully automated SMT lines, through-hole assembly & inspection lines, and fully automated conformal coating lines — configured to each customer's production needs.
Front-end advanced packaging builds interconnects and stacking on wafers with micron-level precision; back-end packaging and test assembles chips into qualified devices. Together they form a complete closed loop of advanced packaging.
