Copper-clad laminates
CGA-500
- Copper-clad laminates
- High Frequency Type
- ROHS Directive
overview
This copper-clad laminate uses glass cloth impregnated with fluoroplastic containing special filler as the dielectric.While retaining the properties of fluoroplastic, it has extremely low water absorption compared to resin-based resins.
Applications
Satellite communication/Satellite broadcasting/Receiving LNB/Transmitter
structure
Features
●Suitable for mass production applications while maintaining the high frequency characteristics of fluoroplastic substrates.
●The dielectric constant is 3.0.

*The standard dielectric constant is 3.00, but the value varies depending on the thickness.
*The standard tolerance for dielectric constant is ±0.10 for each type.
*The standard copper foil is 1/2 oz. or 1 oz. electrolytic copper foil on both sides. If you require electrolytic copper foil of other thicknesses, single-sided copper foil, rolled copper foil, or special dimensions, please contact us separately.
