Energy PCB Assembly Solutions
Why Energy Electronics Manufacturing Is Different
Energy electronic products often operate under high temperature, humidity, outdoor exposure, vibration, high current, and long service life requirements. Compared with consumer electronics, these systems typically demand higher reliability, stronger environmental resistance, and more stable long-term performance under continuous operation.
Applications such as energy storage systems, solar inverters, EV charging equipment, and industrial power electronics require significantly higher standards in soldering reliability, thermal management, testing coverage, manufacturing traceability, and supply chain stability. Small manufacturing inconsistencies may directly affect system safety, product lifespan, and operational stability.
As products scale from prototype to mass production, many manufacturers still face challenges related to process consistency, product reliability, engineering coordination, testing efficiency, and delivery stability.
Common PCBA Manufacturing Challenges

Energy Storage & Power Electronics PCB Assembly– FAQ
For high-power applications, materials such as high-Tg FR4, polyimide, or metal-core PCBs (MCPCB) are commonly used. These materials provide better thermal stability, insulation performance, and mechanical strength under high current and temperature conditions.
Power electronics PCBs usually require 2 oz to 10 oz copper thickness or higher, depending on current requirements. Thicker copper helps reduce resistance, heat generation, and voltage drop.
Thermal management is achieved through a combination of design strategies, including the use of thermal vias and copper pours to enhance heat dissipation, integration of heat sinks or metal substrates for improved thermal transfer, careful component spacing with optimized layout to reduce heat concentration, and the selection of materials with high thermal conductivity to ensure overall system stability and reliability.
Main challenges include soldering large copper areas, managing heat dissipation during the reflow process, preventing board warpage and delamination, and ensuring robust, reliable solder joints for power components.
A hybrid assembly approach is used, combining SMT (Surface Mount Technology) for control circuits with Through-Hole Technology (THT) for high-power components, enabling optimized performance and enhanced reliability.
We follow strict creepage and clearance standards, use insulation materials, and perform high-voltage testing to ensure safety and compliance with international standards.
Common surface finishes include ENIG (Electroless Nickel Immersion Gold), HASL (Hot Air Solder Leveling), and Immersion Silver, with the selection depending on factors such as thermal performance, solderability, and the operating environment.
We employ optimized reflow profiles, selective soldering for THT components, and high-quality solder materials, supported by advanced inspection methods such as AOI, X-ray, and SPI to ensure consistent quality and reliability.
Typical testing includes electrical testing for continuity and isolation, functional testing under load conditions, in-circuit testing (ICT), high-voltage (hipot) testing, and thermal cycling tests when required to ensure reliability and performance.
Yes, we provide full BMS PCBA support, including cell monitoring circuits, balancing circuits, communication modules such as CAN and UART, as well as safety and protection circuits.
We carefully control reflow temperature profiles, select heat-resistant components, and apply optimized PCB layout and thermal design to ensure stable performance and reliability.
