Amid the rapid development of the new energy vehicle industry, the stability of automotive electronic systems directly determines vehicle safety and performance. As the core carrier, the reliability design of PCBs (printed circuit boards) has become a focus of industry attention. Dongguan Jinglin Communication Technology Co., Ltd. is deeply engaged in the electronics manufacturing field. Leveraging its core technological advantages in turnkey PCBA assembly, PCBA assembly, PCB assembly, and SMT manufacturing, it provides high-reliability automotive electronics PCB solutions to leading automakers such as Tesla and BYD, revealing the "security secrets" behind automotive electronics.
Automotive electronics PCBs differ fundamentally from consumer electronics and must withstand complex operating conditions such as high temperatures, vibration, and electromagnetic interference, placing stringent demands on their design and manufacturing. Jinglin Communication has established a comprehensive process control system for reliability design. Initially, they collaborated with automakers to conduct demand analysis and customize PCB layer structures and material selection for diverse application scenarios, such as motor controllers, in-vehicle radar, and battery management systems (BMS). For example, they used high-temperature FR-4 substrates and high-thermal-conductivity copper foil to enhance heat dissipation and aging resistance. In SMT manufacturing, they introduced high-precision placement machines and AOI optical inspection equipment to precisely place ultra-small 01005 components, ensuring a 99.99% solder joint pass rate and eliminating the risk of cold solder joints and desoldering.
As a company with turnkey PCBA assembly services, Jinglin Communication offers a one-stop solution from PCB design, component procurement, assembly, and testing, significantly shortening the R&D cycle for automakers. For example, the in-vehicle control system for a BYD new energy vehicle has been optimized, raising the PCB's vibration resistance to IPC-A-610 Class 3. This ensures signal transmission stability even in extreme temperature cycling tests from -40°C to 125°C. To meet the high integration requirements of Tesla's autonomous driving system, the company uses high-density interconnect (HDI) technology for PCBA assembly, enabling greater component integration within a limited space. Furthermore, the product undergoes three optical inspections and high- and low-temperature aging tests to ensure long-term product reliability.
In addition, Jinglin Communication has established a dedicated automotive electronics production line, strictly adhering to the IATF 16949 quality management system. Complete production data is retained for each batch of products, enabling full lifecycle traceability. Currently, the company's automotive electronics PCB solutions cover multiple areas, including powertrain, body electronics, and smart cockpits. In addition to Tesla and BYD, the company also serves numerous new energy vehicle component manufacturers, making it a reliable partner in the automotive electronics supply chain. In the future, Jinglin Communication will continue to invest in research and development, focusing on new technological trends such as 800V high-voltage platforms and silicon carbide (SiC) modules, optimizing PCB reliability design and SMT manufacturing processes, and providing safer and more efficient electronic manufacturing services for the new energy vehicle industry.
