Electric Vehicle (EV) Electronics PCB Assembly
High-voltage BMS, OBC, motor controllers, and ADAS PCBAs for the electric vehicle industry. IATF 16949-aligned quality, AEC-Q qualified components, zero-defect manufacturing.
PCBA Manufacturing for Electric Vehicle (EV)
The electric vehicle industry is the fastest-growing segment in electronics manufacturing, driven by the global transition to zero-emission transportation. EV electronics are uniquely demanding: battery management systems (BMS) operate at high voltages with safety-critical functions, on-board chargers (OBC) must handle high-power conversion with extreme reliability, and ADAS systems require the highest levels of functional safety (ISO 26262).
Kingdta has developed specialized capabilities for EV electronics manufacturing, including high-voltage PCBA processes, conformal coating for moisture and vibration protection, and IATF 16949-aligned quality management. We source AEC-Q100/Q101 qualified components from authorized distributors to ensure the automotive-grade reliability that EV applications demand.
Our experience spans the full spectrum of EV electronics: from compact BMS cell monitoring boards to high-power OBC assemblies, from motor controller gate driver boards to ADAS sensor fusion PCBAs. We work with EV startups, Tier 1 suppliers, and established OEMs at all stages from prototype to production.
