With the global automotive industry accelerating towards electrification and intelligence, new energy vehicles (NEVs) have become the core direction of industry development. The power battery system, motor control system, and electronic control system (three-electric systems) of NEVs have extremely stringent requirements for the reliability, safety, and high-temperature resistance of core circuit components. Our Automobile New Energy PCBA is specifically engineered for the unique operating environment of NEVs, integrating advanced high-voltage circuit design, automotive-grade high-reliability components, and strict manufacturing quality control. It delivers stable performance under extreme conditions such as high voltage, high temperature, and strong vibration, and is widely applied in key systems of NEVs. We provide global new energy vehicle manufacturers and parts suppliers with professional, customized PCBA solutions to empower the innovation and upgrading of new energy vehicle technology.

　　1. Professional High-Voltage Circuit Design: Adapt to NEV Core System Requirements. Our R&D team, composed of senior electronic engineers with rich experience in new energy vehicles, focuses on high-voltage safety, anti-interference, and thermal management in circuit design. For PCBA applied in power battery management systems (BMS), we optimize the battery cell monitoring, voltage sampling, and balancing circuit design to ensure accurate monitoring of battery state of charge (SOC) and state of health (SOH), and realize efficient battery balancing. For motor control unit (MCU) PCBA, we adopt high-performance power device driving circuits and precise current sampling technology to ensure stable and efficient operation of the motor. For vehicle control unit (VCU) PCBA, we design multi-channel signal acquisition and processing circuits to achieve coordinated control of the entire vehicle. Meanwhile, we carry out strict EMC (Electromagnetic Compatibility) design to avoid electromagnetic interference between various systems, and optimize thermal layout to solve the heat dissipation problem of high-power components, ensuring stable operation under high-temperature conditions (up to 150℃).

　　2. High-Grade Component Selection: Foundation of NEV Safety and Reliability. We adhere to the principle of selecting automotive-grade high-reliability components from well-known international suppliers (such as TI, Infineon, STMicroelectronics, and TDK) to ensure the safety and durability of PCBA. All components comply with AEC-Q100/101/200 automotive-grade standards and are specially selected for NEV high-voltage, high-temperature operating environments, including high-voltage capacitors, high-current connectors, and automotive-grade MCU chips. These components have passed rigorous tests such as high-temperature aging, thermal shock, vibration, and high-voltage insulation. All incoming components undergo strict inspection, including appearance inspection, electrical performance testing, high-voltage insulation testing, and authenticity verification, to eliminate unqualified components and lay a solid foundation for product reliability.

　　3. Advanced Manufacturing & Assembly Technology: Guarantee of High-Voltage Safety and Precision. Equipped with state-of-the-art SMT (Surface Mount Technology) production lines dedicated to new energy vehicles, including high-speed precision chip mounters (placement accuracy up to ±0.03mm), reflow ovens with multi-zone precise temperature control, and AOI (Automated Optical Inspection) equipment with high-voltage component detection capabilities. We implement strict high-voltage PCBA manufacturing processes, including high-precision solder paste printing, high-voltage component special placement, reflow soldering, and through-hole assembly. For key high-voltage PCBA, we adopt double-sided conformal coating technology (silicone or acrylic) to enhance corrosion resistance, moisture resistance, and insulation performance. We also support advanced packaging technologies such as high-power MOSFET and IGBT assembly. Each production process is monitored in real-time by professional technicians and intelligent equipment, with special inspection of high-voltage solder joints to avoid defects such as cold solder joints, short circuits, and missing components, ensuring high-voltage safety and assembly precision.
