High-speed PCB

At China 365PCB, we specialize in the design, fabrication, and assembly of High-Speed Printed Circuit Boards (PCBs) that are critical for next-generation digital and RF systems. Backed by our advanced PCB manufacturing services, we deliver high-precision boards with consistent quality and performance for demanding high-speed applications. Our manufacturing expertise ensures precise impedance control, minimized signal loss, and superior electromagnetic performance—delivering the foundation your high-speed designs demand for reliable, first-pass success.

Our Core Capabilities

Advanced Materials & Substrates365PCB works with industry-leading low-loss, low-Dk/Df laminates (including Rogers, Taconic, Isola, Panasonic Megtron 6/7, and Nelco) to perfectly meet your specific high-signal-speed, multi-gigabit performance, and rigorous thermal management requirements.

Precision Impedance Control & VerificationWe guarantee ultra-tight impedance tolerances (typically ±10%, down to ±5% upon request) for single-ended and differential pairs. This is achieved through strictly controlled dielectric thickness, ultra-precise copper trace geometry, and advanced simulation-backed stackup manufacturing processes.

High-Density Interconnect (HDI) IntegrationExpert engineering for complex layouts, utilizing laser microvias, stacked/blind/buried vias, and fine-line tracing (down to 2/2 mil mil line/space) to seamlessly support high-pin-count, fine-pitch BGAs (0.4mm pitch and below) and advanced chip-scale packages common in high-speed hardware design.

Comprehensive Signal & Power Integrity SupportOur proactive in-house DFM analysis targets high-speed bottlenecks upfront—minimizing EMI/crosstalk, optimizing return paths, managing trace skew, and ensuring robust power integrity. All processes are cross-optimized with our turnkey PCB assembly services to guarantee a seamless transition from prototyping to mass production workflow.

Key Technologies & Features

✦ Back Drilling (Controlled Depth) Precisely removes unwanted via stubs to completely eliminate signal reflections, crucial for maintaining signal integrity at 28Gbps, 56Gbps, and higher multi-gigabit rates.	✦ Any-Layer HDI & Via-in-Pad Provides ultimate routing flexibility, reducing layout space, minimizing parasitic inductance, and optimizing performance in extremely dense, space-constrained, high-frequency layouts.
✦ Stripline & Microstrip Configurations Advanced layer stack-up construction engineered specifically for controlled impedance transmission lines, maintaining uniform RF environments throughout the entire PCB substrate.	✦ Advanced Surface Finishes Full availability of high-tier surface plating options including ENIG, ENEPIG, Immersion Silver, Immersion Tin, and Hard Gold to perfectly suit different operating signal frequencies and assembly requirements.
