04About
12 years building boards that work in the hardest conditions.
Shenpuneng Electronics (深圳市深普能电子有限公司) was established in 2014 in Shenzhen — a manufacturing city that needs no introduction among global electronics engineers. Over the past twelve years the company has built its reputation as a specialist contract PCBA manufacturer for sectors where board failure is not an option: automotive control systems, industrial automation, semiconductor test equipment, and energy storage management.
The factory operates from a 20,000 square metre campus purpose-designed for high-reliability PCBA. Production is organised around dedicated lines for automotive-grade assembly, standard industrial and commercial boards, and a specialist cell for semiconductor test fixtures and ATE loadboards. Each line maintains its own process controls, preventing cross-contamination between quality tiers. Monthly capacity across all lines exceeds 200,000 printed circuit board assemblies.
Shenpuneng's deepest differentiation is in the semiconductor test board segment. As China's domestic IC design industry has grown rapidly, the demand for custom burn-in and functional test boards has outpaced the capacity of traditional test equipment suppliers. Shenpuneng fills this gap with a dedicated engineering team that handles both PCB layout and assembly, delivering controlled-impedance test fixtures from Gerber files to tested boards in as little as ten working days — a lead time that matters enormously when IC development schedules are compressed.
The energy storage business unit, launched in 2023, focuses on battery management system PCBAs for the fast-growing ESS and EV sectors. The team has developed standardised BMS platform designs supporting 3S to 96S cell configurations, which can be customised to customer specifications while reducing engineering lead time. Customers include ESS integrators in Germany, battery pack manufacturers in South Korea, and EV charging infrastructure developers across Southeast Asia.
General Manager Zhou Haitao leads a team of engineers and production specialists who have spent their entire careers in Shenzhen's electronics manufacturing ecosystem. The company welcomes overseas buyers directly — no trading company layer — and General Manager Zhou is reachable via WhatsApp for technical qualification discussions.
