Custom Power PCBA Board | High-Reliability Power Supply PCB Assembly
Power PCBA board is what keeps your product running. Whether it’s a compact consumer device or an industrial system, the Power PCBA board inside it handles the conversion, regulation, and distribution of power—safely, efficiently, and reliably, day after day.
We build custom Power PCBA board solutions for exactly that. From AC-DC power supplies to DC-DC converters, from low-power portable devices to high-power industrial systems, we deliver boards that handle the heat, meet safety standards, and perform consistently from prototype to mass production.
What We Build: Power PCBA for Every Application
- AC-DC power supply PCBA for mains-powered devices
- DC-DC power conversion PCBA for voltage regulation
- High-power industrial PCBA for heavy-duty systems
- Low-power power management PCBA for battery-operated devices
- Automotive-grade power PCBA for vehicle systems
- Medical safety-certified power PCBA for healthcare equipment
- High-power density PCBA for new energy and storage
What Makes Our Power PCBA Board Different
High Efficiency, Less Heat
Low-loss circuit design, high-performance semiconductors, optimized layout minimize energy loss and thermal issues.
Thermal Management That Actually Works
Heavy copper (2oz to 10oz), thermal via arrays, smart component placement for better heat dissipation.
Built to Meet Safety Standards
Proper creepage/clearance, reinforced insulation, and integrated protection circuits (overcurrent/voltage/heat/short-circuit).
Reliable Where It Matters
Industrial/automotive-grade components, robust PCB construction, and tight process control for harsh environments.
More Power in Less Space
High-integration layout for compact form factors without performance compromises.
How We Build Them: Power-Specific Quality Control
A defect in a power board is a safety risk—we don’t cut corners. Every board gets:
- 100% incoming inspection of power semiconductors/materials (full traceability)
- IPC-A-610 compliant SMT assembly (optimized for high-power components)
- AOI and X-Ray to catch hidden soldering defects
- ICT to verify all components and circuits
- Full functional test (input/output voltage, efficiency, load regulation, protection)
- High-voltage insulation/withstand testing for safety compliance
For high-reliability applications, we add:
- Burn-in aging test
- Thermal cycling
- Vibration testing
Where Our Power PCBA Boards Get Used
- Industrial Automation: Switching power supplies, servo drives, UPS, automation power control
- Automotive Electronics: On-board DC-DC converters, OBC control boards, BMS, auxiliary power
- Medical Equipment: IEC 60601-compliant power supplies (safety-certified)
- Consumer Electronics: Fast charging boards, appliance motor controls, portable device power
- New Energy & Storage: PV inverter boards, energy storage systems, EV charging pile assemblies
- Telecommunications: Base station/network equipment power boards
