1. HDI PCB Manufacturing: Precision and High-Density Performance

What Is HDI PCB?

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.

Key Advantages of Ring PCB HDI Manufacturing

• 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.
