Our Capabilities

Built for High-Frequency Signal Integrity

Our high-speed PCB manufacturing uses premium low-Dk/Df materials and tight impedance tolerances to ensure clean, reliable signal transmission at data rates from 10Gbps to 112Gbps+.

📡

Signal Integrity Design

Expert stack-up design with controlled impedance for differential pairs (90Ω, 100Ω), single-ended lines (50Ω), and RF trace routing to minimize insertion loss and crosstalk.

📊

Impedance Control ±5%

Tight tolerance impedance control within ±5% across the panel. TDR testing available for critical high-speed channels to verify impedance consistency.

🏗️

Advanced Stack-up

Customized multi-layer stack-up designs with prepreg spreading control, ensuring consistent dielectric thickness and uniform cross-section for uniform impedance.

Low-Loss Materials

Megtron 6/7, Rogers 4000/3000, Isola I-Tera, and Panasonic Megtron materials for minimal signal attenuation at high frequencies.

🔬

Back-drilling & Stub Control

Laser/microvia back-drilling eliminates stubs on through-vias, maintaining signal integrity at high speeds. Available up to 32 layers.

🔍

TDR & Electrical Testing

Time-Domain Reflectometry (TDR) testing, S-parameter measurement, and 100% electrical testing to guarantee high-speed channel performance.
