What is The TFA Series Laminates?
PTFE ceramic composite dielectric substrate TFA series of products of the dielectric layer composition of PTFE resin and ceramic, do not use the glass fiber cloth dipping method to make prefabricated sheet, but the use of new technology to make prefabricated sheet, and then pressed by a special pressing process. The dielectric constant of this series is 2.94, 3.0, 6.15, 10.2. With the same level of dielectric constant excellent electrical properties, thermal properties, mechanical properties, is aerospace grade high frequency high reliability materials, can replace similar foreign products.
This series of substrate does not contain glass fiber cloth, using a large number of uniform special nano-ceramics and resin mixture, electromagnetic wave propagation without glass fiber effect, excellent frequency stability, dielectric loss of the same level of the lowest, the material X / Y / Z the lowest anisotropy, the material at the same time has the same as the copper foil low thermal expansion coefficient, stable dielectric temperature characteristics.
These laminates comes standard with RTF low roughness copper foil, which reduces conductor loss while providing excellent peel strength. TFA294 and TFA300 can be matched with buried 50Ω resistive copper foil to form resistive film sheets. The circuit board can be processed by standard PTFE sheet technology. The excellent mechanical and physical properties of the sheet make it suitable for multilayer, high multilayer and backplane processing; at the same time, it shows excellent processability in the processing of dense holes and fine lines.
