Shenzhen Hejin Circuit Co.,Ltd.
Shenzhen Hejin Circuit Co., Ltd. is a high-tech enterprise based in Shenzhen, China, focused on the research, development, production, and export of high-precision printed circuit boards (PCBs) and related thermal management solutions. Established in August 2008, the company operates across a manufacturing footprint of approximately 5,000 square meters and staffs more than 360 employees. The organization emphasizes the design and fabrication of advanced PCB technologies, including high-thermal-conductivity aluminum PCBs, copper PCBs with thermoelectric separation, copper-aluminum PCBs, iron substrate PCBs, COB (chip-on-board) mirror PCBs, rigid-flex PCBs, and double and multi-layer FR4 PCBs, complemented by SMT assembly capabilities.
Shenzhen Hejin Circuit positions itself as a comprehensive supplier in the electronics manufacturing space, with particular strength in heat-dissipation-focused PCB solutions. The firm leverages thermoelectric separation techniques to address heat management challenges in high-power LED applications, targeting performance improvements in LED lighting products and related electronics where effective thermal control is critical. The company’s portfolio is tailored to meet a range of industrial needs, spanning LED lighting, high-power power supplies, automotive electronics, machinery controls, and telecommunications equipment where reliable circuit performance is essential.
Quality assurance and compliance are core pillars for the organization. All products reported by the company have undergone testing aligned with European Union standards, including SGS-ROHS and SGS-REACH audits, reflecting a strong commitment to environmental and safety requirements in its manufacturing processes. The company has established an ISO 9001:2000 Quality Management System certification, in addition to RoHS Environment Management System certification and UL certification, with UL’s file number E365537 indicating formal recognition of safety and reliability practices. This quality framework supports the company’s ability to meet stringent customer specifications and international market expectations.
The product development approach at Shenzhen Hejin Circuit emphasizes precision and thermal performance. By exploring high-precision aluminum PCBs and copper-based solutions that incorporate thermoelectric separation technology, the company aims to optimize heat dissipation for high-wattage LED systems, typically within the 100W to 1000W range. This focus addresses a key bottleneck in high-power lighting and electronics, where inadequate cooling can limit performance, reduce reliability, or shorten service life. Through continuous R&D efforts, the firm continues to refine material choices, structural configurations, and production processes to deliver stable, repeatable results across diverse production runs.
In terms of application, Shenzhen Hejin Circuit’s offerings are aligned with sectors that depend on robust electrical performance and thermal management. LED lighting remains a prominent market, but the company also targets related segments such as automotive electronics, industrial machinery, power electronics, and telecommunications where precise PCB capabilities and regulated thermal behavior contribute to overall system reliability. The integration of SMT assembly into the manufacturing workflow supports end-to-end production of assembled PCB solutions, enabling customers to source both bare PCBs and fully assembled modules from a single supplier when compatible with project requirements.
The company’s strategic positioning reflects a manufacturing-focused profile rather than a traditional freight forwarding operation. As a result, the core strengths lie in engineering expertise, process control, quality management, and compliance with international standards. For customers seeking to procure high-performance PCBs with rigorous reliability criteria, Shenzhen Hejin Circuit offers a combination of technical capability and certified quality assurance that supports global export activities, even as the organization remains primarily a PCB producer and supplier rather than a logistics service provider. While explicit logistics offerings such as warehousing, international freight, or customs services are not highlighted in the accessible materials, the company’s emphasis on regulatory compliance and certified production readiness indicates readiness to engage in cross-border supply chains where PCB components are part of broader electronics manufacturing workflows.
Overall, Shenzhen Hejin Circuit Co., Ltd. presents itself as a Shenzhen-based high-tech PCB manufacturer with a clear focus on heat-dissipation-enabled PCB solutions and a robust quality and compliance framework that supports international trade. The combination of advanced material capabilities, thermal management innovations, and a tested quality infrastructure positions the company to serve customers who require reliable, certified PCBs for high-performance electronics across global markets.
