2-Layer RF-10 PCB 0.3mm Thin Immersion Gold Finish for High-Frequency RF Applications

1.Introduction

RF-10 copper clad laminates are composites of ceramic-filled PTFE and woven fiberglass, engineered to deliver superior performance in high-frequency RF applications. These laminates excel in size reduction for RF circuits while maintaining low dielectric loss and excellent dimensional stability. The smooth, low-profile copper bonding ensures minimal insertion losses, especially critical at higher frequencies where skin effect losses dominate. RF-10 is a cost-effective substrate with industry-leading delivery times, making it a preferred choice for demanding RF and microwave designs.

2.Key Features

Dielectric Constant: 10.2 ± 0.3 at 10GHz, enabling compact circuit designs.
Low Dissipation Factor: 0.0025 at 10GHz for minimal signal loss.
Thermal Conductivity: 0.85 W/mk (unclad) for effective heat dissipation.
CTE Stability: Low expansion rates (x: 16 ppm/°C, y: 20 ppm/°C, z: 25 ppm/°C).
Moisture Resistance: 0.08% absorption for reliable performance in humid environments.
Flame Retardant: V-0 rating for enhanced safety.

3.Benefits
