Copper-clad laminates

CHUKOH FLO™ Copper-clad laminates are the products that have placed electrolytic copper foil onto one side or both side of laminated fluoroplastic impregnated glass fabric or laminated fluoroplastic film.
With our original fluoroplastic impregnated technology, we provide a circuit board which has accuracy in thickness and dielectric constant and have excellent results for developing the communication technology over years.
- Characteristics
•This product has excellent heat resistance.
•A stable dielectric constant is ensured in a wide frequency band range.
•An extremely low dielectric tangent is ensured in a high frequency
band range.- Explanation of product code
