HDI & Multilayer PCB Manufacturing - 4-20 Layer Boards with 0.1mm Microvias and 3mil Trace/Space
With over 17 years of professional experience, Ring PCB stands as a leading PCB manufacturer in China, specializing in HDI PCB manufacturing, multilayer PCB fabrication, and full-turnkey PCBA assembly.
Operating two modern factories with a combined area of 5,000+ square meters in Shenzhen and Zhuhai, and staffed with over 500 skilled employees, Ring PCB delivers comprehensive printed circuit board manufacturing from prototype to mass production, meeting global industry standards such as ISO, UL, and RoHS.
We offer customized PCB and PCBA manufacturing for diverse industries, including telecommunications, automotive, medical devices, industrial automation, and consumer electronics.
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
