Teflon Woven Glass Fabric Copper-Clad Laminates
Teflon woven glass fabric copper-clad laminates are formulated with varnished glass cloth, prepreg, and Teflon PCB resin through scientific formulation and strict technology procedures. These materials offer several advantages over the F4B series in terms of electrical performance, including a wider range of dielectric constants, low dielectric loss angle tangent, increased resistance, and more stable performance.
