RF-10 copper clad laminates are composites of ceramic filled PTFE and woven fiberglass. RF-10 has the advantage of high dielectric constant and low dissipation factor. Thin woven fiberglass reinforcement is used to offer both low dielectric loss and improved rigidity for ease of handling and improved dimensional stability for multilayer circuits.

RF-10 laminates are engineered to provide a cost effective substrate with industry acceptable delivery times. RF-10 responds to a need in RF applications for size reduction.
