Copper-clad laminates

CHUKOH FLO™ copper clad laminates are products made by laminating fluoroplastic impregnated glass cloth or fluoroplastic film, and then heat-fusing electrolytic copper foil onto one or both sides. Our unique fluoroplastic impregnation technology allows us to provide substrates with precise thickness and dielectric constant, and we have a long and extensive track record in the development of communication technology.
