FSD1020T High-Frequency Laminate Custom PCB – 0.508mm RF Substrate with ENIG Finish for Microwave & UAV Applications

FSD1020T High-Frequency Laminate & Custom PCB Product Introduction

Product Overview

The FSD1020T is a high-performance RF microwave laminate based on a low-loss hydrocarbon resin and nano-ceramic composite system, manufactured by leading domestic technology in China. It serves as an ideal alternative to traditional PTFE-based substrates, offering exceptional dielectric properties and thermal reliability for high-frequency and high-speed circuit designs.

The core technological advantage of FSD1020T lies in its unique low-loss carbon-hydrogen nano-ceramic composite architecture. Compared to conventional PTFE materials, FSD1020T not only delivers outstanding high-frequency electrical performance but also provides superior mechanical workability and dimensional stability. The material complies with IPC-4103 standards, has achieved UL94 V-0 flame rating, and meets halogen-free and RoHS environmental requirements.

The FSD1020T exhibits stable and consistent dielectric constant along with extremely low dissipation factor at 10 GHz — a critical attribute for high-frequency signal transmission, as lower loss factor translates to reduced signal attenuation and superior transmission quality. The material also demonstrates excellent performance in millimeter-wave bands.

The high Tg (280°C) of FSD1020T ensures excellent heat resistance during lead-free soldering processes, while its low CTE values across all three axes provide outstanding dimensional stability and reliable plated through-hole (PTH) reliability. The material's superior CAF (Conductive Anodic Filament) resistance further enhances long-term reliability in high-voltage and high-humidity environments.

Key Technical Parameters

These outstanding insulation characteristics make FSD1020T particularly suitable for high-voltage and high-current RF power applications.
