Product Overview
GT1350 high frequency circuit material is a product of special enforcement by glass fibre composed with PTFE, which can provide excellent electricity and mechanical stability. It is a kind of high dielectric constant circuit board material which can carry out a lot of information processing under UHF (GHz).It is an ideal material for RF and Microwave application areas. Dielectric constant is 3.5, dissipation factor is 0.0040, which can meet the performance of the design. Combined with glass fabric, the lamination surface is smooth that PTFE can use the standard PTFE printed circuit board to process the treatment technologies.
