Our two self-owned factories in Shenzhen and Zhuhai, China, cover more than 5,000 square meters and are equipped with advanced SMT lines, automated inspection systems, and professional testing facilities. Supported by 500 skilled employees, Ring PCB handles prototyping, small-batch orders, and high-volume production with equal expertise.
Technical Challenges and Solutions
Manufacturing up to 48-layer PCBs requires advanced control of lamination pressure, dielectric thickness, and signal impedance. Ring PCB’s experienced engineering team ensures:
Perfect layer registration and consistent lamination quality.
Controlled impedance for high-speed and RF applications.
Excellent thermal management for power and industrial systems.
High reliability in harsh operating environments.
Comprehensive testing to guarantee performance and long-term stability.


Modern industrial control devices are becoming smaller yet more powerful. This trend pushes PCB manufacturers to offer:
Fine trace routing
Controlled impedance
Multi-layer stack-up optimization
Rigid-flex structures
Professional PCB manufacturing and assembly for industrial control ensures electrical performance without compromising mechanical strength.
