Product Overview
We are a professional custom PCBA (Printed Circuit Board Assembly) factory dedicated to providing high-performance, high-reliability, and fully customized power solution motherboards for our clients. From consumer electronics to industrial equipment, our PCBA motherboards meet diverse power management needs, offering one-stop services from design to mass production.
Core Advantages
1. Fully Customized Design
Circuit design and optimization based on specific client requirements (input/output specifications, dimensions, interfaces, environmental adaptability, etc.).
Supports multiple topologies (e.g., switching mode, linear, UPS).
Provides schematic design, PCB layout, thermal management, and EMC optimization support.
2. High-Quality Components & Manufacturing
Industrial-grade or automotive-grade electronic components ensure stable operation in harsh environments.
Fully automated SMT lines and through-hole assembly ensure soldering precision and consistency.
Compliant with IPC-A-610 Class 2/3 standards, with AOI and X-ray inspection.
3. High-Efficiency Power Management Performance
Wide input voltage range (e.g., AC/DC 85V-265V or DC 12V-48V).
High conversion efficiency (up to 95%+), low power consumption, and low ripple noise.
Integrated OVP, OCP, SCP, and OTP protection features.
4. Flexible Production – From Prototype to Mass Volume
Supports prototype, pilot run, and large-scale production with short lead times.
Delivers PCBA semi-finished boards or full assembly (including enclosure, heat dissipation, and connectors).
