Professional Custom PCB Manufacturing & Assembly Solutions Since 2008 | Ring PCB
Ring PCB is a professional manufacturer specializing in Multilayer PCB Manufacturing and Full Turnkey PCB Assembly services. With 17 years of experience in the printed circuit board industry, we focus on providing high-reliability, custom-built PCBs and PCBA solutions for industrial automation, power systems, robotics, and energy control equipment.
We are a manufacturing and assembly company — not a design house. Customers provide complete design files such as Gerber, BOM, and assembly drawings, and our experienced production team transforms them into finished, high-performance products. Every board we produce is manufactured under strict quality control and in full compliance with ISO9001, ISO14001, ISO13485, and IATF16949 certifications.
2.Key Features and Advantages
Custom Multilayer PCBs manufactured based on your drawings or technical specifications.
Layer capability up to 48 layers for complex and high-density industrial systems.
Full Turnkey PCB Assembly service including component sourcing, SMT, DIP, and testing.
Excellent heat dissipation, impedance control, and high-voltage reliability.
Strong resistance to environmental stress such as temperature variation and vibration.
Fast production cycle: 3-day prototype and 7-day batch manufacturing available.
Advanced equipment and production lines in our 5000㎡ self-owned factories in Shenzhen and Zhuhai.
Over 500 skilled employees ensuring precision, flexibility, and consistent delivery quality.
Exported to more than 50 countries with long-term global partnerships.
3.Technical Strength in Manufacturing
Industrial control applications require stable, high-current, and low-noise circuit operation. To meet these needs, Ring PCB uses advanced manufacturing technologies such as:
Laser Direct Imaging (LDI) for precise inner-layer patterning.
Vacuum lamination to ensure perfect layer bonding and dimensional stability.
CNC drilling and laser micro-vias for accurate interlayer connections.
Automated Optical Inspection (AOI) and X-ray testing for zero-defect assurance.
Controlled impedance design and copper thickness management for power stability.
Each multilayer PCB undergoes strict electrical testing, solderability inspection, and functional verification before shipment — ensuring reliable operation in industrial automation environments.
