F4BTMS430DK4.3 F4BPCB 2-layer 125mil 3.175mm Thick F4BTMS Series Substrate Circuit Board

Product Overview

The F4BTMS430 PCB is a high-reliability, 2-layer printed circuit board constructed using F4BTMS430 F4B substrate, a ceramic-filled PTFE (Polytetrafluoroethylene) laminate designed for aerospace, RF, microwave, and radar applications. With a thickness of 3.175mm (125 mil), this 125mil F4BTMS PCB offers exceptional thermal stability, low dielectric loss, and superior signal integrity in high-frequency environments.

Engineered to meet IPC-Class-2 standards, this DK4.3 PCB features a black solder mask, white silkscreen, and HASL (Hot Air Solder Leveling) surface finish, ensuring durability and reliable solderability. The low CTE (Coefficient of Thermal Expansion), high thermal conductivity (0.63 W/mK), and ultra-low moisture absorption (0.08%) make it ideal for harsh environments, including space, military radar, and satellite communication systems.

F4BTMS Introduction

Built upon the successful F4BTM series, the F4BTMS430 high frequency PCB represents a significant technological breakthrough in material formulation and manufacturing processes. The base material, F4BTMS430, is enriched with ceramics and reinforced with ultra-thin and ultra-fine glass fiber cloth. This novel composition enhances material performance, expands the range of dielectric constants, and positions the PCB as a superior alternative to similar foreign products.

The unique mixture of ultra-thin glass fiber cloth, polytetrafluoroethylene resin, and special nano-ceramics drastically minimizes the negative effects of glass fiber on electromagnetic wave propagation. This results in reduced dielectric loss, improved dimensional stability, decreased X/Y/Z anisotropy, and enhanced electrical strength and thermal conductivity. Moreover, the F4B PCB supplier’sF4BTMS430 PCB exhibits exceptional low thermal expansion coefficient and stable dielectric temperature characteristics, allowing it to excel in demanding applications.
