2-Layer RT/duroid 6002 High-Frequency PCB – 30mil (0.8mm) with Immersion Silver Finish
Product Introduction
We present our 2-Layer RT/duroid 6002 PCB – a premium high-frequency circuit board engineered for demanding microwave and RF applications. Fabricated with Rogers RT/duroid 6002 ceramic-filled PTFE laminate and finished with Immersion Silver, this 0.8mm (30mil) board delivers ultra-low loss (Df 0.0012 @ 10 GHz), exceptional dielectric constant stability (Dk 2.94 ±0.04), and outstanding dimensional stability. The absence of solder mask and silkscreen, combined with the Immersion Silver finish, provides a pure, low-loss RF path ideal for phased array antennas, radar systems, and space-grade electronics.

Why RT/duroid 6002?
RT/duroid 6002 is a ceramic-filled PTFE composite engineered for complex microwave structures requiring a low dielectric constant and ultra-low loss. Unlike standard RF laminates, it offers a remarkably low thermal coefficient of Dk (12 ppm/°C), ensuring stable performance across wide temperature swings. With a decomposition temperature (Td) of 500°C and low out-gassing characteristics, it is ideally suited for space applications and other mission-critical environments.
Key Features of RT/duroid 6002
| Parameter | Value |
| Dielectric Constant (Dk) | 2.94 ±0.04 @ 10 GHz |
| Thermal Coefficient of Dk | 12 ppm/°C |
| Dissipation Factor (Df) | 0.0012 @ 10 GHz |
| Td (Decomposition Temp.) | 500°C (TGA) |
| Thermal Conductivity | 0.6 W/m/K |
| CTE – Z axis | 24 ppm/°C |
| Moisture Absorption | 0.02% (ultra-low) |
Benefits of This RT/duroid 6002 PCB
Ultra-Low Loss: Df of 0.0012 at 10 GHz minimizes insertion loss – ideal for long RF traces and high-sensitivity receivers.
Tight Dk Control: ±0.04 tolerance ensures predictable impedance and phase matching for phased array and beamforming networks.
Temperature Stable: Low thermal coefficient of Dk (12 ppm/°C) maintains consistent performance across operating temperature ranges.
Copper-Matched CTE: In-plane expansion coefficient matched to copper – excellent dimensional stability for temperature-sensitive applications.
Low Out-Gassing: Ideal for space applications, satellite communications, and vacuum environments.
Immersion Silver Finish: Provides a flat, solderable, low-loss surface with excellent conductivity and RF transparency. No solder mask or silkscreen eliminates dielectric interference on RF traces.
Multi-Layer Ready: Excellent mechanical and electrical properties support reliable multi-layer board constructions.
