The Copper-clad laminated circuit board using flouroplastic impregnated glass fabric containing inorganic filler as the dielectric.
Obtaining characteristics of fluoroplastic, it also has lower water absorbency than resins.


Satellite communication/Satellite broadcasting/Receiving LNB/Transmitter

Operating temperature range

-60°C to +220°C


CGA-500 Structure


●It is suitable for mass production use while maintaining high frequency characteristics of fluoroplastic substrate.
●It has 3.0 dielectric constant.

General dimensions table

General thickness (mm) Acceptable variation of thickness Dielectric constant Dissipation factor
1020×1220 510×1220
0.4 ±0.05 3 <0.0030
0.5 ±0.05
0.6 ±0.06
0.8 ±0.08
1.0 ±0.10
1.2 ±0.12
1.6 ±0.20

*The dielectric constant is assumed to be 3.00. However, the dielectric constant varies with varying thickness.
The tolerance of the dielectric constant is assumed to be ±0.10 for any one variety.

*As a standard we have used ½ oz. electrolytic copper foil on both sides. For other thicknesses of electrolytic copper foil, copper foil on one side, rolled copper foil, or in the case where other special measurements are necessary, please seek a special consultation from us directly.
