F4BTM High Frequency Laminates
F4BTM series high frequency laminates are made of glass fiber
cloth, nano-ceramic filling and polytetrafluoroethylene resin after
scientific preparation and strict process pressing.
This series of products is based on the F4BM dielectric layer, and
the materials are added with high-dielectric and low-loss nanoscale
ceramics, thus obtaining higher dielectric constant, better heat
resistance, lower coefficient of thermal expansion, higher
insulation resistance, better thermal conductivity, while
maintaining the characteristics of low loss.
