At Ring PCB, we specialize in multilayer PCB manufacturing and SMT assembly services for industries such as automotive, medical devices, telecommunications, industrial control, and consumer electronics. With 17 years of industry experience, we have become a trusted PCB manufacturer and EMS provider known for delivering high-quality, cost-effective, and fast-turnaround solutions.
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.
An HDI PCB (High-Density Interconnect Printed Circuit Board) is designed with finer traces, smaller vias, and higher wiring density to accommodate the miniaturization of modern electronic devices. These boards enable faster signal transmission, improved electrical performance, and lightweight designs.
Advanced Laser Drilling: Microvias as small as 0.1 mm for compact multilayer stacking.
Sequential Lamination Technology: Ensures precise alignment and reliable interconnects.
High Signal Integrity: Optimized impedance control and copper plating uniformity.
Custom Design Flexibility: Accepts customer PCB design files (Gerber) for tailored solutions.
Fast Turnaround: 3-day prototyping and 7-day mass production to accelerate your product launch.
| Parameter | Capability |
|---|---|
| Layer Count | 4–20 layers |
| Minimum Trace/Space | 3 mil / 3 mil |
| Minimum Laser Via | 0.1 mm |
| Copper Thickness | 0.5 oz – 3 oz |
| Material | FR4, High-Tg, Rogers, Polyimide |
| Surface Finish | ENIG, OSP, Immersion Silver, HASL |
| Testing | 100% E-test & AOI Inspection |
Multilayer printed circuit boards allow complex circuitry to fit into smaller footprints, offering enhanced performance for high-speed, high-frequency, and high-power applications. They are widely used in advanced electronic systems that demand stability, signal precision, and compact design.
17 Years of Expertise: Proven experience in multilayer PCB stack-up design and lamination.
Fully Integrated Factory: PCB fabrication, SMT assembly, and testing under one roof.
Strict Quality Control: Each board undergoes 100% E-testing, AOI inspection, and functional testing.
Flexible Order Options: From prototype to high-volume production, with guaranteed consistency.
Custom PCB Solutions: Clients can provide Gerber files, BOMs, and assembly drawings for personalized manufacturing.
Certified: UL, ISO9001, ISO14001, ISO13485, IATF16949
