Introduction

New Energy & Automotive PCB Assembly

New Energy Vehicles (NEVs)—including Battery Electric Vehicles (BEVs), Hybrid Electric Vehicles (HEVs), and Fuel Cell Vehicles (FCVs)—depend on advanced Printed Circuit Board (PCB) assemblies as the core of their electronic systems. These vehicles demand PCBs that deliver exceptional reliability, high-power handling, and superior thermal management to perform safely and efficiently under the most demanding conditions.

Critical Applications of PCBs in NEVs
  • Our PCB assemblies are engineered to meet the rigorous requirements of key NEV systems:
  • Battery Management Systems (BMS): Precisely monitor, balance, and protect battery cells by tracking voltage, current, and temperature.
  • Power Conversion Systems: Form the foundation of high-efficiency inverters, DC-DC converters, and onboard chargers (OBCs).
  • Motor Control Units (MCU): Enable real-time control of motor speed, torque, and direction.
  • Vehicle Control Units (VCU): Act as the central nervous system, managing communication between all vehicle subsystems.
  • ADAS & Infotainment: Power advanced driver-assistance systems, navigation, and the in-vehicle user experience.

    Key Characteristics of Our NEV PCBs
  • High-Power Capability: Designed to withstand the high voltages and currents found in battery packs, inverters, and traction systems.
  • Advanced Thermal Management: Utilizing thick copper substrates, Metal-Clad PCBs (MCPCBs), and strategic thermal vias to dissipate heat effectively.
  • Rugged Reliability: Built to endure extreme automotive environments, including vibration, moisture, thermal cycling, and long operational lifespans.
  • Full Automotive Compliance: Manufactured in IATF 16949 certified facilities and designed to meet stringent standards like ISO 26262 for functional safety and AEC-Q200 for component reliability.
