Product AdvantagesMaterial Benefits

Features premium gold-plated connectors. PCB adopts high-frequency low-loss high-TG substrate with copper thickness up to 1oz. Gold-plated connector terminals deliver excellent conductivity. Reduces issues like wire breakage, speed throttling and lag caused by oxidation and rising impedance.

Design Benefits

Enhanced differential signal layout design. No CAF micro-short phenomenon. High-speed signal transmission avoids signal attenuation and interference from parasitic capacitance and inductance. Reinforced power circuit routing, miniaturized PCB design to lower mechanical interference, no hardware collision and simple installation.

Technical FAQ

✅ What is the cable quality? Does it have shielding?Yes, it comes with metal layer shielding, built with advanced EMI shielding conductive polymer flat cable. Each cable is fully covered by conductive polymer EMI shielding material to block incoming and outgoing electromagnetic radiation, minimize interference and performance degradation while lowering cable weight.

✅ Cable thickness, flexibility & bendability?Cable thickness is only 1.3mm. The flat ribbon cable is soft and flexible. Normal bending will not affect performance.

Important Purchase & Usage Warnings

1. Check connector orientation carefully: Reversed or misaligned insertion may burn your hardware. Hold the socket firmly when plugging in; excessive force may break socket pins. Do NOT bend or pull the cable within 2cm of soldering joints at both ends.
2. Signal driving capability varies among motherboards and hardware devices. Our lab test results do not guarantee identical performance on your equipment. Signal loss is inevitable with extension cables. If you require perfect signal integrity, please do not purchase.
3. Electronic hardware ages and oxidizes over time. Using an extension cable will further reduce stability. NOT compatible with equipment older than 4 years.
4. Sold exclusively for professional engineer lab testing. Not approved for other applications.
