Energy PCBA Application: Powering the Future of Renewable Energy

Empowering Sustainable Energy Solutions with STHL

The new energy sector demands PCBs that can handle high voltages, wide temperature swings, and continuous operation. STHL’s energy PCBA solutions power this transition, with expertise in solar inverter PCBs, wind turbine control boards, and energy storage system (ESS) assemblies. Leveraging 20 years in power electronics, we focus on high-current design (supporting up to 500A), low-loss materials (Rogers substrates for efficiency), and rigorous HALT (Highly Accelerated Life Testing) to ensure longevity in outdoor environments. Our end-to-end process includes sourcing flame-retardant components, thermal simulation, and compliance with IEC 61010 for safety.
