Teflon woven glass fabric planar resistor copper-clad laminates F4BDZ294

1Introduction

F4BDZ294 is a kind of Teflon woven glass fabric planar resistor copper-clad laminates with the dielectric constant of 2.94. This kind of high frequency laminates is manufactured by Teflon woven glass fabricwith low dielectric constant and low dissipation factorwith the planar resistor copper foil. It features with excellent electrical and mechanical performance. Its high mechanical reliability and excellent electrical stability is suitable for the design of the complicated microwave circuit.
