Copper-clad laminates

CGS-500A

  • Copper-clad laminates
  • high-frequency type
  • UL Standard
  • RoHS Directive

Overview

The Copper-clad laminated circuit board using flouroplastic impregnated glass fabric as the dielectric.
Obtaining characteristics of fluoroplastic, it also has stable permittivity in wide frequency band and a very small dielectric loss tangent in the high frequency band.

Main applications

Satellite communication/Satellite broadcasting/All mobile communication systems/ETC or AHS in ITS/Regional wireless communications networks (WLL)/ Ecteina/Artificial satellite-mounted device

Structure

Characteristics

• Compare to CGP, it is the circuit board with lower dielectric constant.
• It has 2.15 dielectric constant.

*CGS-500A has passed the UL certification.
*The tolerance of the dielectric constant is assumed to be ±0.05 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.
