High Speed Circuit - High Speed PCB

In the era of 5G communication, automotive intelligence, and high-performance computing, high-speed PCB (High Speed Printed Circuit Board) has become the core carrier ensuring stable signal transmission in high-frequency systems. Unlike ordinary PCBs, high-speed PCB is specifically designed for signal edge rates<1ns or="" frequencies="">300MHz, solving key challenges such as crosstalk, reflection, and electromagnetic interference (EMI) in high-speed signal transmission through advanced materials, precision design, and sophisticated manufacturing processes.

Core Advantages of Our High Speed PCB

1. Low-Loss Material Solutions

We select high-performance substrates based on application scenarios to minimize signal attenuation:

Entry-Level High-Speed: Rogers RO4350B (Dk=3.48±0.05, Df=0.0031@10GHz) and Taconic RF-35, ideal for 5G FR1 (sub-6GHz) base stations and industrial control systems .

Premium High-Frequency: Rogers RT/duroid 5880 (Dk=2.20±0.02, Df=0.0009@10GHz) for millimeter-wave applications (26-100GHz) such as automotive radar and satellite communication .

Cost-Effective Hybrid Design: Combines high-speed FR4 (e.g., Taiyo TU-872SLK) with PTFE materials to balance performance and cost for data center servers .

Compared to standard FR4 (Dk=4.4, Df=0.02), our high-speed PCBs reduce signal loss by over 40% at 10GHz, ensuring stable transmission of 25Gbps+ signals .

2. Precision Impedance Control & Signal Integrity

Strict Impedance Tolerance: Achieves ±5% control for 50Ω single-ended and 85-100Ω differential impedances (USB/LVDS/HDMI), validated by TDR (Time-Domain Reflectometry) testing .

Advanced Stackup Design: Symmetrical "signal-ground-power-ground" structures minimize EMI. For example, 8-layer boards use 0.2mm core materials to reduce crosstalk by 40% .

High-Speed Routing Optimization: Adopts 45° angles instead of 90° corners, implements 3W rules (line spacing ≥3x line width), and uses back drilling to remove stub lengths<0.5mm, eliminating high-frequency resonance .

3. Advanced Manufacturing Capabilities

High-Precision Processing: Supports 2-40 layers with minimum line width/spacing of 3mil/3mil (0.075mm) and laser-drilled microvias down to 0.05mm, ensuring layer alignment accuracy ≤3mil .

Reliable Surface Treatments: Offers ENIG (Electroless Nickel Immersion Gold), Immersion Silver (optimal for >12GHz), and OSP options. ENIG provides 5-6μm nickel and 0.025-0.127μm gold layers for excellent solderability .

Stringent Quality Control: Complies with IPC-6018D (high-speed PCB standard) and5 and IATF 16949 (automotive grade), with 100% electrical testing and 3D X-Ray inspection, achieving a defect rate<50ppm .

Key Applications Across Industries

5G Communication: 5G macro/small cells (26-40GHz), fronthaul/backhaul modules, and Massive MIMO antennas, supporting 100Gbps+ data rates .

Automotive Electronics: 77/81GHz ADAS radar, in-vehicle Ethernet (1000BASE-T1), operating stably in -40℃~+125℃ environments .

Data Centers & AI: High-speed server backplanes (PCIe 5.0), GPU interconnects (HBM3), and 25G/100G optical modules .

Aerospace & Medical: Satellite Ka-band transceivers, MRI signal processing boards, and millimeter-wave imaging systems requiring ultra-low noise .
