F4BTM450 PCB 2-layer 3.2mm ThickHigh Frequency Circuit Laminate



The F4BTM series of high-frequency circuit laminates offers exceptional performance and reliability for a wide range of applications. These laminates are engineered using a combination of glass fiber cloth, nano-ceramic filling, and polytetrafluoroethylene resin, undergoing rigorous preparation and pressing processes. The F4BTM series is based on the F4BM dielectric layer and incorporates high-dielectric and low-loss nanoscale ceramics. This unique composition results in a higher dielectric constant, improved heat resistance, reduced coefficient of thermal expansion, enhanced insulation resistance, and superior thermal conductivity. These advancements are achieved while maintaining the low-loss characteristics of the material.


Features of F4BTM450

The F4BTM450 variant of the series exhibits outstanding specifications, making it an ideal choice for high-frequency applications. Here are the key features of the F4BTM450 PCB:


1)Dielectric Constant (Dk) of 4.5 at 10GHz:

The F4BTM450 offers a precisely controlled dielectric constant, ensuring reliable signal propagation and reduced signal loss at high frequencies.


2)Dissipation Factor of .002 at 10GHz:

With an impressively low dissipation factor, the F4BTM450 minimizes energy loss during signal transmission, resulting in improved signal integrity.


3)Coefficient of Thermal Expansion (CTE):

CTE x-axis: 10 ppm/°C

CTE y-axis: 12 ppm/°C

CTE z-axis: 51 ppm/°C

These CTE values indicate the excellent dimensional stability of the F4BTM450 across various temperatures, enabling reliable performance in demanding environments ranging from -55°C to 288°C.


4)Low Thermal Coefficient of Dk:

The F4BTM450 exhibits a low thermal coefficient of dielectric constant, with a range of -60 ppm/°C from -55°C to 150°C. This characteristic ensures consistent electrical performance under temperature variations.


5)Minimal Moisture Absorption:

With a moisture absorption rate of only 0.05%, the F4BTM450 maintains its electrical and mechanical properties even in humid conditions, making it suitable for diverse environments.
